Glazing of balconies with an aluminum profile is an economy class option. We glaze the balcony on our own: three main options Glaze the balcony with an aluminum profile with our own hands

Balcony glazing aluminum profile today considered one of promising options finishes. Cold glazing is considered the most common, and if you do not plan to arrange on the balcony warm room, then such glazing will be as efficient and economical as possible.

What is attractive about such balcony glazing

This option is not able to fully protect against frost in winter, but in spring and summer the balcony turns into a comfortable veranda. The aluminum profile has advantages and disadvantages, let's talk about them in more detail. TO positive properties can be attributed:

  • price
  • light weight
  • Save space with sliding doors
  • long-term operation without repair
  • minimal care

The full cost of such structures allows you to glaze the balcony compartment at no extra cost, which primarily affected their popularity. The price of cold-type aluminum profiles is much lower than wooden or metal-plastic ones. Therefore, if not planned, then this choice is more preferable.

Aluminum itself is a light metal. Thanks to this, the frames are also lightweight, some types do not weigh more than 20 kilograms. They are convenient to transport, bring into the house and install on site without the need to mount additional partitions in the frame of the window structure.

Cold glazing of aluminum profile balconies in most cases involves the installation of sliding doors, the operation of which is more convenient. In addition, this type of opening is safer. After all, swing frames, if they are not fixed, can be damaged by a strong wind, while sliding structures used without additional fasteners.

The simple design of aluminum frames and resistance to corrosion makes them extremely resistant to various loads. There is nothing to break in them, and the double-glazed windows used can withstand any wind vibrations. They do not require careful maintenance. It is enough to wipe them with a soft cloth with soapy water. You can not worry about the safety and repair for at least 10-15 years.

Cons of aluminum frames for a balcony

What's wrong with aluminum frames? Their main disadvantage is their high thermal conductivity. Hence the definition - cold glazing. The aluminum profile has no additional thermal insulation (except for the fact that it is made using thermal break technology). Therefore, on a balcony or loggia, the temperature in winter will be almost the same as on the street.

Also, aluminum frames have low sound insulation. The low tightness of the structure allows everyone to enter the room more or less loud sounds. Only the overall background noise is reduced.

Aluminum Frames - Structural Design

Today, there are many design options for window and balcony structures. When ordering an individual option, you can make an application for spraying paint of any shade - for example, the facade of your house. Glasses can be chosen both ordinary and tinted, the price will be slightly different from the standard design.

A simple assembly process allows you to make glazing with an aluminum profile various forms and sizes, up to panoramic. But when using plastic structures it would be extremely difficult and expensive to do so.

What if you have a small balcony or loggia, and there are a lot of plans to use this room? The light weight of aluminum makes it possible to manufacture structures for them with a "removal". In this version, the frame, as it were, protrudes slightly beyond the level of the parapet, thereby increasing the usable area and allowing you to organize a large window sill on one or three sides.

Do-it-yourself installation of aluminum profile frames

For the installation of cold glazing on a conventional balcony structure or loggia, the following materials are needed:

  1. Window unit assembled. The design includes: frame, ebb, window sill, visor and sashes.
  2. Several sheets of galvanized steel.
  3. Fasteners: self-tapping screws, anchors, dowels, bolts and rivets.
  4. Mounting foam and silicone-based sealant.
  5. If necessary, rollers, additional profiles, latches and clips.

When ordering glazing, all elements must be supplied with the design, if something is missing, then you can buy it yourself.

The key to success in any endeavor is good preparation. In this case, you will have to dismantle the old balcony frame in advance. The level of complexity depends on the material of its manufacture. If you have a wooden structure, then it is not difficult to break it. Things are much more difficult if necessary to dismantle the iron balcony frame. You will have to cut it off with a grinder and knock out the fixing wedges from the walls. After that, it is necessary to remove all debris from the balcony and clean the parapet and walls before installing a new frame.

First, an "apron" is installed. Installation of this element is necessary if metal handrails are additionally installed on the parapet. In this case, an "apron" made of galvanized iron sheets will cover them. If there are no handrails, then the frame is mounted directly on a concrete or brick parapet. For ease of fastening, experts recommend first laying a wooden beam.

The visor is installed second. Although the structure made of aluminum profiles is not subject to decay, this element will prevent excess moisture from entering the frame, while protecting it from dirt and dust. It is attached with a slight slope towards the concrete slab located above the balcony.

Important! The length of the finished visor should correspond to the size of the balcony.

After mounting the visor, the frame is installed. To fix the aluminum structure, it is first necessary to install anchor plates on the parapet and on the upper horizontal plane, to which the frame will be attached. Installation is carried out with appropriate bolts, as a rule, they are sold together with plates. Some experts practice installation only on mounting foam. This is the wrong approach. The fastening must be rigid, and the foam will not be able to sufficiently give the structure the necessary rigidity and resistance to loads, as is the case with anchor bolts.

After fixing the frame, window sashes are hung. Here, the works are distributed depending on the type chosen: swing or sliding. In the first version, they are mounted on hinged structures, as a rule, already built into the frame, in the second version, skids are installed first, and then window blocks.

When everything is assembled, it is necessary to walk with mounting foam at all the points where the frame joins the wall, ceiling and parapet. Use a special nozzle to fill even small gaps, cold wind can penetrate through them and snow can get in in winter.

And the last step will be the adjustment of the frame fittings. At correct installation sashes (swing or sliding) should move smoothly, without effort. If there are slight deviations, it is necessary to adjust the hinges or guides. For this, special bolts are provided, allowing you to adjust the location of the fittings to required angle tilt. You need to unscrew them, fix the sash in place, tighten it and try how it will “walk”, and if necessary, repeat the procedure again.

Standard cold glazing designs are considered the budget version. They fulfill their intended purpose - they protect from wind and moisture, but are not able to withstand frost in winter. In such cases, it is recommended to use a profile with a thermal break.

Many people do not plan to use a balcony or loggia as an extra room. But at the same time they want to make staying on the loggia comfortable, to protect it from rain and snow. It is for these purposes that aluminum loggias have been developed, which are also called cold glazing.

After glazing the balcony, you can perform "light" insulation with a waterproofing layer. Thick penofol, with one-sided foil coating, will be quite enough for these purposes. After that, problems with blowing balconies disappear.

Advantages and disadvantages of aluminum glazing

As the name implies, such glazing of balconies is made with an aluminum profile. Such windows are new for our country, so you need to talk about the advantages of this system:

  • First of all, it must be said that such structures are sliding. That is, they do not swing open like ordinary windows, but travel along the window on guides - special skids. This achieves significant savings in space, which is not enough on the loggia.
  • Such glazing with an aluminum profile is much lighter than PVC, which is very important for balconies. In some cases, you can do without reinforcing the parapet.
  • Lightweight design allows for remote glazing balconies, which increases the total volume of the room.
  • Many manufacturers offer installation with a tinted profile, the richness of the palette of which will allow sliding windows to fit seamlessly into the existing facade design.
  • The resistance of aluminum to various aggressive influences and environments determines its durability in the open air.
  • Ordering a sliding frame that is not designed for thermal insulation will cost significantly less than a similar PVC window.

Preparation

The preparatory stage includes the following steps:

  • The first step is to remove the old frame. All manipulations should be carried out carefully so as not to damage the integrity of the parapet.
  • Then all remnants of fasteners and other debris are removed.
  • The cracks formed during the dismantling process should be carefully sealed with mortar.

After the opening is prepared, glazing can be installed.

Installation of aluminum structures

Before starting installation, you need to make some manipulations with the aluminum profile, which will make it easy to install the sliding structure:

  • It is necessary to remove the sliding structural elements from the frame. This will greatly facilitate installation.
  • It is necessary to remove the glazing from the fixed parts of the frame so as not to break it during installation.
  • Then mounting plates are attached to the frame with a step of no more than 70 cm.
  • The frame prepared in this way is installed in the window opening and fixed with wedges.
  • The frame is exposed along the planes, after which it is fastened through the mounting plates using dowels.

Advice! In the process of fastening, it is necessary to ensure that the frame "does not lead" and does not warp. In some cases, you will need to slightly loosen the mount in order to adjust the plane with the profile.

Installing and adjusting glazing

Having securely fixed the frame, the previously removed glazing is installed in the fixed parts. Then the sliding part of the structure is installed, the guides easily allow this to be done.

Now you need to adjust the sliding of the valves. This is done by special screws that control the smoothness of the slide. At this stage, fittings are also installed: handles, locks and more. optional equipment. After that, the sliding doors close and move on to the next step.

Window sill installation

The installation of this element is carried out in the following sequence:

  • It is necessary to adjust the window sill so that there is no gap between it and the frame. If necessary, the rear edge is trimmed.
  • Having adjusted, the window sill is removed, it is applied to the place of its installation polyurethane foam.
  • After that, it is installed in place, aligned and loaded so that there are no shifts.

Construction sealing

Having fully assembled and fixed the window unit, it is necessary to fill all the remaining slots and joints with mounting foam. Fill the gaps with foam to 3/4, leaving room for the expansion of the sealing material. Such an operation will increase the reliability of the structure, exclude blowing and moisture ingress into the balconies.

WITH inside all gaps between the frame and the walls are closed plastic platbands, giving the sliding structure completeness.

Advice! After installing the aluminum frame and filling all the cracks with foam, you need to let the structure “settle” until the mounting foam has completely hardened. After 24 hours, the sliding aluminum structure can be fully used.

The installation of aluminum sliding structures is quite justified for glazing if it is not planned to attach a loggia or balcony to the total living area of ​​the apartment. In this case, lightweight and cheaper aluminum profiles are the best choice. At the same time, the space of balconies is significantly saved due to the convenient opening of the window.

Balcony glazing is one of the most important activities in the process of apartment renovation. Firstly, it is necessary for the insulation of housing, because a significant part of the heat comes out through the balcony. Secondly, after installing windows there, you get additional space that can be used for certain residential or household needs. But, before starting work, you need to decide what material the glazing should be made of. And one of the popular options is aluminum windows to the balcony.

Installation aluminum windows on the balcony today is increasingly gaining popularity. And for those who are just thinking about this, we will give the pros and cons of such glazing. Let's start with what advantages aluminum windows have on the balcony.

  1. Availability. Often people prefer aluminum windows just because of the low cost. On average, the price for them is 1.5-2 times cheaper than for similar glazing with PVC windows.

  2. Light weight. Aluminum itself is a very light metal. Accordingly, all structures made from it, including window frames and shutters for the balcony. And because of this property window structures exert little pressure on the parapet. Therefore, aluminum windows are suitable for installation on balconies located in emergency houses. In addition, it is much easier to carry and install.
  3. High sound insulation. Due to the hermetic frame and tight closing of the sashes, aluminum glazing will protect your home from extraneous noise from the street.

  4. Attractive appearance and the possibility of painting aluminum windows in different colors.
  5. Ease of care– the outer surface of the aluminum glazing frames and sashes is covered with a water-repellent film. Due to this, the product is less prone to pollution from dust and precipitation. Therefore, caring for such frames is much easier than for wooden structures - you just need to wipe the inside and outside with a wet cloth once every few weeks.

  6. High strength and durability- aluminum windows, despite their relative lightness and cheapness, are very strong structures. Their service life is measured in three to four decades.

Important! For owners small apartments it makes sense to consider the option of glazing the balcony with aluminum windows with a perimeter exceeding that of the parapet. As a result, the usable area of ​​the balcony increases and can be used for location indoor plants in the warm season or as an additional refrigerator in winter.

Also, when thinking about purchasing aluminum windows for a balcony, you should be aware of their shortcomings. The main disadvantage of such structures is the insufficient degree of thermal insulation. A balcony with aluminum windows, as a rule, will be "cold" - in winter the temperature in it will exceed that on the street by no more than 5-6 ° C.

The design of a balcony or loggia in Provence style is becoming fashionable among our compatriots. They are attracted by low-key elegance, French simplicity, natural materials finishes and the presence of vintage elements. For a more detailed acquaintance with the issue, we recommend reading.

Another disadvantage is that aluminum frames and sashes are installed only on perfectly flat and pre-prepared surfaces. Therefore, before the installation process begins, the parapet will either have to be leveled with a cement mixture, or a wooden board should be placed under the structure and all the glazing elements should be installed on it.

Aluminum windows to the balcony - step by step installation instructions

Now that you know about all the features, advantages and disadvantages of aluminum windows to the balcony, let's look at how the installation takes place.

List of tools

But before starting work, any master needs to stock up on a set of tools. You can get acquainted with the list of what you need to install aluminum windows on a balcony from the table below.

Table. Installation of aluminum windows on the balcony - the necessary tools.

Important! It is desirable that the screwdriver has two batteries - while one is working, the other is charging. After they change places. Thus, the continuity of the workflow is achieved.

Dismantling old glazing - step by step instructions

Before proceeding with the installation of new aluminum windows on the balcony, it is necessary to get rid of the old glazing.

Step 1. The dismantling of the old glazing begins not with the breaking of window frames, but with preliminary measurements. Using a tape measure, the length, height and depth of the opening on the balcony are determined. Without these data, it is impossible to choose an aluminum glazing that is suitable in size.

Step 3 The building level is carried out along the upper part of the balcony opening - it is necessary to find out how even the concrete slab is, whether there are distortions there. Such defects are characteristic of old houses in disrepair, and this must be taken into account when installing aluminum windows on a balcony.

Building levels

Important! In the process of performing all measurements, it makes sense to record the results of the work. Craftsmen working in window and balcony glazing companies use standard forms for this purpose, as in the image below. You can also use a regular piece of paper for notes.

Step 4 Only after all measurements have been completed, you can begin to dismantle the old glazing. Work begins with the removal of the sashes from the hinges. If they (sashes) are in a satisfactory condition, then the process is done carefully, using a screwdriver. But more often, the sashes of the old balcony glazing are removed using scrap. Much faster, more efficient and safer, such work is done in pairs.

Step 5 The window sill and the ebb are tucked in and removed with a crowbar. If they hold on too tightly and tightly and simply cannot be dismantled, then the craftsmen resort to using a hammer and a chisel - the latter is driven in between the parapet and the window sill (or low tide) in several places. Then scrap is inserted into the gaps formed, the glazing part is hooked and removed from the fasteners.

Step 6 Then, with a conventional wood saw, cuts are made at several points on each side of the window frame. This operation greatly facilitates the subsequent process of dismantling the structure, making it possible to remove it in small parts.

Step 7 The sawn parts of the balcony glazing frame are removed from their place and removed to the rest of the construction debris. If necessary, resort to the use of scrap.

Step 8 After removing all parts of the old glazing, the opening on the balcony is protected from concrete fragments, individual small parts of the frame or from fasteners. Then small irregularities are cleaned. Whole construction garbage, obtained during the dismantling of the old glazing, is disposed of.

Important! Before installing aluminum windows, serious defects and unevenness of the window opening are eliminated with cement mortar.

Installation of aluminum windows on the balcony - step by step instructions

Now that the balcony opening is free of old and worn-out glazing, new aluminum windows are being installed. As in the previous section, information about this case is presented in the form of a step-by-step instruction.

Step 1. In this example, the alignment of the edge of the parapet is done by setting wooden planks. They are fixed on long self-tapping screws screwed into the concrete. In this case, the boards are aligned horizontally using the building level.

Step 2 Delivered aluminum window parts are unpacked, counted and checked for defects. Then from individual elements frames are assembled - while rubber gaskets are inserted between them, necessary to seal the joint. The parts are connected to each other with self-tapping screws.

Step 3 According to the same principles that were outlined in the previous operation, all other frames are assembled. As for the sashes, they are usually delivered ready-made - assembled and glazed.

Step 4 Anchor plates are installed on the upper part of the frame, with the help of which the structure will be connected to the ceiling on the balcony. Places for installation are not chosen by chance - from the edge of the frame to the anchor plate should be no more than 20 cm, and the interval between the elements should not be more than 40 cm.

Step 5 A window sill is installed on top of the board laid on the parapet. For starters, it aligns horizontally.

Step 6 Then the window sill is fixed on the board with self-tapping screws screwed into the part.

Step 7 By the same principle, the second window sill is laid and fixed. In this case, both parts should fit tightly with each other, and their edges should lie on the same line.

Step 8 A metal tide is laid on the outer side of the parapet over the newly installed window sill. It is fixed with small screws.

Step 9 Another low tide is laid nearby, while it not only joins with the previous one, but overlaps with it, as shown in the image below.

Step 10 From one of the edges of the balcony, the installation of the aluminum window frame begins. One of her constituent parts inserted into the opening and fixed there from the bottom up. Its vertical position is controlled by the building level.

Step 11 Part of the aluminum frame is attached to the parapet with self-tapping screws. They are inserted into the corresponding holes in the bottom part and twisted with a screwdriver.

Step 12 Another part of the frame is installed next to it. Then it joins with the glazing element installed in the previous operation. Fixation is carried out using self-tapping screws screwed into the side parts of both parts of the aluminum frame.

Step 13 Holes are drilled in the concrete slab on the ceiling of the balcony for attaching the anchor plates. Then dowels are inserted there and self-tapping screws are hammered. The latter fix these plates, and at the same time parts of the aluminum frame from the upper side of the opening.

Perforators

Step 14 Between the balcony ceiling and top edge the aluminum frame is started up and a visor is installed from the outside, which is necessary to protect the glass from pollution during rains and other precipitation. The visor is fastened with self-tapping screws, screwed through the holes in the anchor plates.

Step 15 The “visor-frame” and “frame-outflow” joints are treated with silicone sealant - not a single drop should penetrate through them into the balcony, even with the heaviest downpour.

Step 16 On special fasteners and guides of the aluminum frame, the shutters are installed - both rigidly fixed and movable. At the same time, it is checked whether the latter can walk freely and how well the windows on the balcony open and close.

Upon completion of all the above operations, the installation of aluminum windows on the balcony can be considered successfully completed. Now you can get all the benefits of modern and high-quality glazing.

IN Lately the balcony is increasingly becoming like one additional rest room. People place chairs and small tables there for talking over a cup of coffee on fresh air. Make it more comfortable and functional. Less and less often, the balcony began to resemble a pantry or a room for storing unnecessary things. In order for beauty to be not only internal, but also external, people began to resort to aluminum glazing. Indeed, in addition to the modern appearance, such a design has a large number of other benefits.

Installation of an aluminum balcony

In most cases, a balcony is a room that is not heated additionally. Installing additional battery sections there is a complex, costly and impractical business. Previously, we used to see with a wooden bottom or slate. The frames were also usually made of wood, and the sashes opened inwards. But this design, although inexpensive, had its drawbacks. Especially in winter, constant drafts appeared due to cracks in the tree, snow fell on the ledges located between the upper and lower parts. When it melted, water could get inside the room, and if frost hit, it could also spoil the material from which the structure was made. Therefore, people are increasingly resorting to more modern materials, which are not subject to such shortcomings as, for example, a tree. Most people leave the lower part of the structure opaque, and glaze the top with aluminum or PVC. Sometimes you can see fully glazed balconies. For these types, aluminum frames are used exclusively. Modern window sashes can be both sliding and outward opening. Both the first and the other option significantly save space indoors. Mounting a balcony made of aluminum, as well as from any other material, has its advantages and disadvantages.

pros Minuses
The most important advantage is its cost. It is an order of magnitude lower than when using, for example, plastic. Even with a small amount of money, you can transform your balcony. Poor thermal insulation properties. For regions with severe winters, this option is not suitable. But on the other hand, there is a technology of "warm aluminum", which does not have such problems.
A light weight. The design weighs quite a bit, which allows it to be easily installed in houses where it is forbidden to heavily weight the balcony. It will be impossible to use other materials for finishing the room. If this is neglected, then an irreversible chemical reaction. The metal will begin to correct.
Fire safety. Aluminum will not be able to ignite when hit, for example, by a cigarette butt from above.

By choosing this design, you can significantly save on inner space rooms. And the system of sliding windows will allow you to wash them with convenience and comfort.

If you want to isolate yourself from the outside world, noisy streets and enjoy the warmth and comfort of home, then this is what you need. After all, the construction of aluminum allows you to improve sound insulation. In addition, the material is resistant to atmospheric phenomena and temperature differences.

Do-it-yourself aluminum balcony installation

Of course, it is much easier to call a team of professionals who can quickly install aluminum balcony. After all, they already have their own scheme of work, technologies and certain skills. But with a certain skill, there will be no problems with self-assembly. To do this, you first need to carry out some preparatory procedures. After all, the outcome of all work will depend on them:

  • First of all, the old frames are removed. When dismantling, the force must be directed parallel to the frame, not perpendicular. Otherwise, there is a chance to break the design of the parapet.
  • After that, you need to get rid of the fasteners and the remnants of concrete that were not removed along with the old frame and remained on the parapet.
  • If the parapet is not even enough, then it can be further leveled with a solution in order to subsequently fix the aluminum structure on it. If this stage is present, then it is better to postpone the installation of the balcony until completely dry. concrete mix. Usually one day is enough.
  • In order for the window frame to be more securely fixed, it is necessary to install a wooden beam with a cross section of at least 50 millimeters. This will also create better thermal insulation between himself concrete structure and aluminum profile.

To make the installation process easier and more convenient, you need to carry out several preparatory steps:

  • All moving parts that are on the aluminum structure are removed. This action will facilitate further installation work.
  • Double-glazed windows are removed from the "deaf" areas of the frame. Thanks to this, they will not be damaged during installation work.
  • Using metal screws, special plates are attached along the window frame. Their step must be at least 700 millimeters.
  • The assembled structure is placed on the railing of the balcony.
  • You need to take a level for construction in order to align the frame in a horizontal position. From below the frame is fixed with self-tapping screws.
  • Vertical frames are mounted with wooden wedges. After that, holes are drilled in the walls and in the upper ceiling using a puncher. For fasteners, it is better to use anchors. Before attaching the structure to the upper part, a thin metal visor is screwed to it - galvanized or black metal with a protective coating.
  • Next, you need to construct an ebb at the lower fragment of the frame. Fixing to the aluminum profile occurs with the help of self-tapping screws for metal.
  • Using mounting foam, all slots and holes are blown out.
  • After that comes the turn of installing double-glazed windows in "deaf" zones.
  • The last is the return to the previous position of the moving fastener parts.

Such simple procedures will help to qualitatively install a balcony from an aluminum profile and significantly save the budget on calling specialists.

Do-it-yourself aluminum frames for a balcony

Aluminum frames last longer than wood or other materials. This is due to the fact that this metal does not corrode. The service life of an aluminum window frame can reach fifty years. Metal does not require any additional care. It is non-toxic, non-flammable and is considered an ideal option, as it is not flammable. The frames from it are strong, reliable and plastic, so you can install windows of any size and appearance. But good thermal conductivity is considered the main disadvantage of using aluminum for a window frame. But this shortcoming was quickly eliminated by design engineers.

At the moment there are two types of aluminum profiles on the market: cold and warm. The first is much cheaper than the second, and if you take into account the other distinctive features, then this is a great option for a window frame if the balcony will not be all year round act like another living room. Cold profile frames are quite thin, so it is easy to make sliding doors out of them, which will save the balcony area. The warm profile includes an additional heat-insulating insert structure made of polyamide. It is located in the center between the inner and outer half of the profile. In this case, the double frame with a double-glazed window becomes much thicker. Only one thing can scare a person - high price. But when the balcony will be used as a living space in winter, then the frames from a warm profile - perfect option. In addition, fashionable aluminum double-glazed windows can be designed in a modern and varied design, and can be opened in a variety of ways.

How to install aluminum frames on the balcony yourself

After the frames with the appropriate measurements have been purchased, the most important point- installation. Do-it-yourself installation saves a lot cash and thanks to detailed instructions, will not be difficult. The first step is to acquire devices that will be useful for further work:

  • hacksaw for metal;
  • roulette;
  • drill;
  • self-tapping screws;
  • screws;
  • screwdriver;
  • brush seal;
  • weatherproof silicone sealant;
  • mounting foam;
  • hex key.

For high-quality glazing, it is necessary to carry out actions in the following order:

  1. If the previous window frame is present, then disassemble it.
  2. We clean the dirt and parts of the skin from the parapet and slab.
  3. We assemble a new frame from the elements.
  4. We fix the assembled elements of the installation on the parapet using galvanized self-tapping bolts and mounting loops.
  5. After we take measurements of the length of the horizontal part of the opening, transfer the measurement values ​​to the guides and then cut them. After - the guides for the sashes are mounted.
  6. Using a file, we polish the sawn area.
  7. In the openings, we drill holes for self-tapping screws with an interval of 30 centimeters. We install guides on the screws. In order to avoid freezing of the frame, the distance from the outer edge of the frame to the guides must be no more than 5 centimeters.
  8. We install the brush seal along the line of the valves.
  9. We insert the sash first into the upper guide, and the part on which the rollers are located - into the bottom.
  10. We install a steel visor under the mounting loops.
  11. We attach it from the top concrete slab self-tapping screws.
  12. We draw on the ebb on a strip of steel and cut it out with roofing scissors.
  13. Installing a tide.
  14. Seal the joints with weatherproof silicone sealant.
  15. We blow out all visible cracks with mounting foam.
  16. Installing blind glazing.

With the help of such instructions, mounting the window frame will not cause difficulties.

How to install an aluminum loggia

It is better to use cold glazing for the loggia, in the case when the balcony does not turn into a separate room. Aluminum frames look dignified due to the fact that they are painted using a modern powder method. They are an order of magnitude stronger and lighter than plastic, which makes the installation process more convenient. In addition, a lot of light enters the room, as they practically do not darken the space. These designs do not require periodic intervention of professionals for preventive maintenance. Modern designs allow you to create a six-leaf window, each leaf of which can be opened separately. The pressure on the leaf bearings is minimal. This extends the service life. Due to the low weight of the frames, any loggia can easily withstand them.

Aluminum doors open and close silently and smoothly. For tight closure, the frame is fixed with a special lock, which is invisible from the outside. The strength of a thin frame is able to hold the glazing of the loggia up to two meters in height. Aluminum loggias are installed only when it is necessary to protect as much as possible from the wind or other adverse weather conditions. If desired, sliding and fixed doors can be combined. There are usually two or three guides on an aluminum profile. Each video moves in its own way. If desired, a mosquito net is installed on the loggia. A separate guide is provided for it.

For cold windows, single-chamber double-glazed windows are usually installed. In warm windows there is a thermal insert or a thermal bridge. But it is located in the middle of the profile, the thickness of which is not less than 12 centimeters. If desired, the aluminum structure can be combined with wood. Then the strength of the metal and the "breathing" properties of wood will help resist strong condensation. In addition, wood has excellent thermal insulation characteristics and is environmentally friendly. To install the aluminum structure on the loggia, first remove all movable opening elements for ease of use from the frame. In order not to spoil the glazing, it must be removed from blind areas. Next, mounting plates are fixed to the frame using self-tapping screws. Then assembled structure installed in the opening of the loggia. Then the frame is aligned with wedges in all planes. Mounting plates are attached to the walls and the top. Then it is checked how evenly the frame is installed, and the sashes return to their previous position. After that, the sealing process takes place.

Do-it-yourself balcony glazing with an aluminum profile

As mentioned earlier, there is nothing complicated in the process of glazing a balcony with an aluminum profile. Even if there are no relevant skills, then thanks to detailed instructions, it will not be difficult to carry out glazing. But sometimes a person wants to enjoy the views from the window without any restrictions. For this purpose, you can use the method frameless glazing. It is no less durable and reliable than with a frame. chief bearing element construction in this embodiment, an aluminum profile is considered, which is attached to the top plate.

The guide rail, also known as the lower profile, is fixed on the parapet post. The enclosing parts of the structure are tempered glass, their thickness should be 6-8 millimeters. The canvases move thanks to a special sliding mechanism, which is located at the top of the profile. If there are uneven or rounded areas on the balcony, then a roll is made there. The joints of the panels are closed with tape, which easily transmits light. The shutters open one after the other in turn. When choosing this type of glazing, special attention is paid to such indicators as reliability, durability and stability.

Do-it-yourself installation of an aluminum balcony video

Do not forget that when self-assembly aluminum balcony, you need to leave gaps for mounting foam, two or three centimeters under the windowsill. All manipulations should be carried out with the presence of a plumb line and level. The video shows good example how to properly mount an aluminum balcony with your own hands:

Have you heard about the cold glazing of the balcony? But many do not know about this technology. Clients often come to our office and are not even aware that this happens.

I really hope that many readers will draw useful information from it and be aware of all the nuances when ordering cold glazing. Knowledge is power! Read.

The term "cold glazing" should be understood as turnkey glazing of a balcony, where the installation process takes place without the use of a thermal insert, but thanks to aluminum profiles.

The presented type of glazing is perfect for non-residential rooms.

Cold glazing ensures that no noise from the street is heard in the apartment, and also protects the rooms from rain, snow and freezing.

Cold glazing can be done in the following ways:

  1. Glazing with aluminum structures without thermal breaks by sliding systems. This method is very convenient, because it allows you to save space on the balcony and you can open it by moving the profiles to the sides. In addition, this type of glazing is recognized as environmentally friendly, because it is made from materials that do not have a negative impact on human health, as well as pets. Systems based on aluminum profiles are lightweight and will last for many years. Before installation, preliminary measurements should be carried out. Then frame frames are made, into which steles from 5 millimeters thick are inserted. You can even build window sill to save space.
  2. Glazing with deaf or pivot windows. Can install mosquito net, because in the summer it is hot and there is no desire for flies and mosquitoes to fly into the apartment.

It should be noted that there is no heat-insulating air cushion in cold glazing, therefore total weight systems are smaller and the load on the bearing surfaces is the smallest.

Cold glazing is used only when the balcony serves only for storing things, because the temperature inside will be only 7 degrees higher than the street temperature.

Advantages of cold glazing

  • A small price for expenses and installation;
  • Significant space savings due to sliding doors;
  • The profile can be painted in any color;
  • All structures that are used during installation are fire resistant, durable and strong;
  • Cold glazing is universal and will suit all loggias and balconies;
  • Protects the apartment from noise, snow and dust from the street.
  • Cold glazing is the most common option, because this way you can glaze all balconies and loggias. Sliding frames are very and allow you to save the area of ​​​​the balcony. Frames can be installed on a metal parapet and on a concrete or brick base.

Aluminum glazing of balconies and loggias

Cold glazing is an economical option for protecting a balcony from dampness, wind, snow and street dust.

But an aluminum profile with single-layer glass does not guarantee high thermal protection. In severe cold on the balcony, the temperature will not exceed 0 ° C.

Cold glazing of balconies and loggias with an aluminum profile is the most budgetary option for protecting a balcony from dust, wind, rain and snow.

The company "Windows Forbis" offers to order window structures directly from the manufacturer, which allows customers to pleasantly save on the arrangement of premises, receiving impeccably done work, ready for long-term successful service.

The cold glazing method has its advantages and disadvantages. Among the shortcomings - the lack of sound insulation. Aluminum profile and one glass are not an effective barrier to noise.

Therefore, everything that happens on the street will be heard on the balcony. This point is important to consider if the windows of the apartment face a busy street. Also, cold glazing is not able to retain heat in the cold.

The balcony can only be fully used in summer. And in winter, it can serve as an additional refrigerator. When it's -20°C outside, it's near zero on the balcony.

Aluminum sliding glazing

In all other respects, the aluminum profile shows excellent results. It is extremely easy to use, extremely durable, non-flammable, does not deform and does not change color over time.

The narrow profile blocks out the least amount of light. The light weight of the aluminum structure allows you to install cold glazing on any balcony without prior reinforcement.

This option is suitable even for "Khrushchev", where balcony slabs very weak.

We use semi-coated Guardian glass of increased strength. Glass width 4 mm. Its transparency is higher than that of ordinary glass, it retains excess ultraviolet without reducing the brightness. sunlight and without changing its hue.

The balcony is filled with daylight and does not require additional lighting. This is especially important if you have a lot of indoor plants.

Ways to open windows

Aluminum glazing can be deaf, hinged or sliding. The most commonly used sliding design: it saves scarce balcony space. This design is very convenient to use and has a long service life.

Advantages of aluminum glazing of balconies and loggias

If you doubt the need for glazing balconies, just read the list of advantages that this solution has:

  • affordable installation price;
  • saving space and the appearance of additional space, ready for year-round use;
  • profile reliability and durability;
  • high-quality protection against dust, wind, rain and snow;
  • light weight;
  • resistance to deformation and corrosion;
  • preservation of color and surface smoothness;
  • aesthetic and modern look structures;
  • a wide variety of colors.

If you do not plan to use the balcony in winter period otherwise than just for storing things or products, then cold glazing with an aluminum profile will be an excellent solution to increase usable area housing.

Cold glazing with Provedal profile

Using the Provedal profile, only cold glazing is performed. This is explained by the high thermal conductivity of aluminum.

Aluminum frames do not retain heat well, and the small installation depth of the aluminum profile does not allow the installation of double-glazed windows. A glazing in one glass does not protect against heat loss.

As a result, Provedal is not suitable for residential glazing in cold climates.

Provedal aluminum glazing is optimal for rooms that are not insulated and are used seasonally. The choice of such structures is due to their low weight. Balconies and loggias have different strengths.

Some are not able to withstand the significant weight of plastic frames. Frames made of aluminum are much lighter, easier to install and do not require the preparation of a solid support.

If desired, the aluminum structure can be installed directly on metal fence balcony. This system is also used for summer premises: gazebos, verandas and terraces.

Catalog of Provedal profiles

All types of aluminum profiles can be divided into two types: hinged and sliding. For swing systems p400, for sliding systems - c640. We will discuss the differences between these profiles below.

Swing system Provedal p400

The P400 profile is designed to create hinged window systems.

The design scheme is standard. The sashes are attached to the frame with hinges and open into the room. The rotary handle fixes the closed shutters.

The Provedal p400 swing system is suitable for making windows and doors. And also for hinged partitions and stained-glass windows.

  • Single-chamber profile, 40 mm wide;

P400 profiles are resistant to many negative factors. They perfectly resist high and low temperatures from fifty degrees of frost to fifty degrees of heat, and sudden changes in temperature.

Profiles of this series are used to create glazing of balconies and loggias, doors, partitions in offices and some other structures.

The surface of profile systems is painted. High-quality paint protects aluminum from corrosion processes and makes the structure more attractive aesthetically.

The paint is used in a wide range of colors. It does not fade and retains a rich shade throughout the operation of the aluminum structure.

The p400 profile can be mounted in two ways: with the creation of blind and hinged sashes. The main advantages of this option are the possibility of combining blind and swing doors, the low cost and reliability of the fittings used.

Provedal P400 aluminum profile products are durable and reliable. Their soundproofing characteristics reach 27 dB. The design transfers loads without deformation, cracks and other defects do not appear in it.

The profile is resistant to oxidation and fire. The service life of the aluminum part of the glazing is eighty years or more. Since the window structure consists not only of a profile, its service life is less - about twenty years.

Window frames from the P400 profile are equipped with glasses with a thickness of three to six millimeters. Double-glazed windows are not used in such structures, since this makes no sense. The main heat loss occurs through the profile itself.

Window structures are equipped with seals. They are made from elastomers, the characteristics of which comply with the EPDM standard.

Sliding system Provedal c640

Sliding window structures are equipped with sashes that move sideways along the frame. The movement is provided by a special C640 profile and rollers that are hidden inside the frame.

Hidden location of moving parts allows you to protect them from moisture, dust and debris.

The absence of water prevents icing. Such rollers are very difficult to damage by accident. Thanks to this feature, the design serves for a long time under any weather conditions.

The Provedal c640 sliding system is suitable for glazing balconies, loggias, verandas, terraces and partitions.

  • Single-chamber profile, 60 mm wide;
  • Seals comply with EPDM standard, color black;
  • Sashes up to 1250 mm wide, up to 6 pcs;
  • Profile color is white. Coloring according to RAL is possible;
  • Glazing glass, up to 6 mm thick;
  • Fasteners stainless steel.

Straight profiles are connected using special elements. They are diverse in shape, which allows you to create window structures for balconies of both simple and complex shapes.

In addition to balconies and loggias, sliding aluminum structures are used for glazing terraces and verandas, creating office partitions.

C640 profiles are completed with five-millimeter glasses or double-glazed windows no thicker than sixteen millimeters.

Joints are sealed with special materials, including felt. Polymer elastic materials comply with EPDM standards. The sashes are sealed with brush elements.

The main advantage of the c640 profile is the possibility of using sliding structures and the associated space savings. Deaf and sliding doors can be combined, as well as create complex designs.

When mounting structures from the profile of the C640 series, they are equipped with three types of doors: deaf, sliding and hinged. The number of wings should not exceed six.

In this case, the dimensions of one sash can reach a length of one meter twenty-five centimeters. Weight of each square meter is twelve kilograms.

Most often, the C640 profile is used to create structures with sliding doors. Such a product is completed with no more than six elements that are shifted relative to each other.

Swing doors are used in cases where it is required to increase the level of thermal insulation and tightness. The increase is from ten percent to fifteen.

Sliding structures are the most popular for glazing balcony spaces. This is due to the great ease of use on balconies and loggias of small area or width.

To open the swing doors, you need to free up space in front of them. In conditions of a cramped balcony, this is not always possible. In particular, the person who opens the sash would have to deviate or squat.

Not everyone is able to perform such actions. If you install a design with sliding doors, the process will be simple and convenient. Blinds can be hung on the windows and they will not interfere with the shutters to open.

The only drawback is less tightness, but for an uninsulated balcony it is not essential.

We would like to inform you that when we say “Provedal profile” we mean an aluminum profile for cold glazing. At the moment, Spanish profile systems are not produced or supplied in Russia.

All companies selling “Provedal” in Russia sell cold glazing from profiles produced in Russia, Belarus or China. Such profiles do not differ in quality, and meet all standards and state standards.

Insulation of the loggia with cold glazing

In addition to spacious rooms, the new apartments have huge halls and corridors, storage rooms and dressing rooms. However, the Soviet past does not allow a single centimeter of usable area to be wasted.

And in most cases, a person decides to glaze and insulate an existing balcony or loggia.

Most new buildings are already being designed glazed balconies. Most often, glazing of loggias is done in a cold way, i.e. using a sliding aluminum profile or a wooden frame with one glass.

Cold glazing is very economical option, but not optimal in terms of thermal conductivity.

Therefore, there are always those who want to turn just a loggia into a comfortable additional room. Best result Insulation of a loggia with cold glazing is achieved by insulating all parts of the room: balcony frames, floors, walls and ceilings.

Window insulation

If cold air and moisture penetrate through the window frames into the room, additional insulation of the bindings is necessary. The best way is the processing of the entire perimeter of the inner and outer sides of the frame with a special sealant.

When installing balcony frames, polyurethane foam is often used. Over time, under the influence of aggressive natural factors it collapses, and as a result, cracks form.

Floor insulation

To insulate the floor of the loggia, mineral wool, extruded polystyrene foam, otherwise foam and polystyrene, are most often used.

Mineral wool has excellent heat and sound insulation, resistant to chemicals. However, in some EU countries different kinds mineral fibers are prohibited for use due to their unsafety for human health.

Styrofoam is also an excellent heat and sound insulating material. Non-toxic. However, it is easily destroyed when interacting with many chemicals, such as acetone.

The best option for warming both the floor and walls is penoplex. This material is very durable, has high moisture resistance and low thermal conductivity, and is environmentally friendly.

Between the lags, plates from the selected insulation are laid. The distance between the insulation and the walls must be repaired vapor barrier film or tape, which will help protect the floor from mold.

Wall and ceiling insulation

The walls and ceiling of the loggia are sheathed with 3-centimeter sheets of foam, foam or material with similar characteristics. With the help of dowels, a bar is attached to the walls and ceiling, which is set according to the level.

Facade glazing replacement

In addition to the glazing of buildings under construction, customers face the question of replacing facade glazing.

Many facades built back in Soviet times (starting from the 60s of the 20th century) are morally obsolete, and at most ceased to fulfill their functions as a result of wear and tear.

Therefore, there is a need to replace facade glazing - either part of it (replacing double-glazed windows with energy-saving ones), or dismantling the existing facade and glazing with a new facade system - Schuco or Russian.

Also, the need to replace facade glazing arises for a private customer - when it is necessary to replace cold glazing with warm glazing. This is a fairly common case; facade glazing is especially often replaced by people who have bought an apartment in an elite building in order to expand their living space.

Mostly in modern new buildings in Moscow and the Moscow region, the facades of buildings are glazed according to the principle of cold glazing, as a result of which the residents have the question of replacing cold glazing with warm glazing.

The technology in this case is as follows - our specialists dismantle the old facade glazing, install new pillars and crossbars, install sashes, install double-glazed windows with low-emission glass, and trim the junctions. Then a container for the removal of construction debris is ordered.

Understand the difference between cold and warm glazing

Cold glazing is designed for glazing non-residential premises, and warm glazing for living quarters.

Warm glazing in the profile itself has a thermal bridge to prevent heat loss (if we are talking about aluminum glazing - plastic glazing, or rather, a plastic profile, even a 3-chamber one is initially warm).

Warm glazing has a coefficient of reduced heat transfer resistance (Ropr (m2 °C / W) higher than cold glazing.

When facade glazing is replaced from cold to warm, Ropr increases to 0.54 m2 oC/W. For comparison, this figure for plastic windows is 0.54 m2 oC/W.

Now let's figure out when it is necessary to replace cold glazing with warm one. There are three types of glazing according to thermal insulation characteristics.

  • Warm;
  • Warm-cold;
  • Cold.

If you have warm glazing plastic system with double-glazed windows with energy-saving glass, or an aluminum system with a similar double-glazed window and a thermal bridge, then everything is fine with you!

A warm-cold glazing system, as a rule, is a facade system (consists of pillars and crossbars, a double-glazed window is installed from the outside and pressed from the outside with a clamping bar and a decorative cover), then it is not necessary to replace the facade glazing to seal it.

In this case, the installed glass / double-glazed windows are removed, thermal bridges are installed in the facade system, double-glazed windows are installed (if they pass in size) with energy-saving glasses. If necessary, the sealing rubber is changed.

Note that these types of work are performed by industrial climbers.

The cold glazing system is an aluminum window system consisting of an aluminum one-piece structure.

When replacing facade glazing made in this system, such a system is dismantled (if possible), and a new one is put in its place, warm system made of aluminum or plastic (PVC) depending on the wishes of the customer.

Replacement of cold glazing in a solid glass facade

But here's what to do if your facade is a single whole, starting from the first floor and ending with the last.

Such a facade is hinged, that is, it is not built into the opening, but is hung from the outside, and when one rack ends, the next one comes out of it due to the internal mortgage!

Many companies where you contact regarding the replacement of cold glazing will refuse to insulate such a facade, saying that it is technologically impossible.

And they will be right in their own way. The issue is that when there is a need to replace cold glazing, many companies do not have a technological solution for insulating a part of a cold facade with a warm one, but Deutsche Facade has such a solution!!!

To replace cold glazing, or rather to insulate part of a cold facade, we offer a number of solutions:

  • the racks from below and above are insulated with a heater, thermal bridges are inserted into the racks, ebbs are placed below and above your facade to prevent water from entering from neighbors. The appearance of the facade will not fundamentally change, despite the protrusion from the general facade by 2-3 cm (if you are told that after the insulation the facade will not change at all, then this is not true, or rather, if you put a second glazing thread);
  • another option is to insulate the racks due to the fact that they are removed from the inside into plastic boxes, plastic frames are inserted into the place of the glasses, into which warm double-glazed windows are already installed from the inside. In this option, the facade will be in one line, and the cold glazing will be replaced!

Another way to replace cold glazing with warm glazing is to install a second glazing string. With this option, the original glazing does not change, this type of work is cheaper than replacing facade glazing, since there is no work of climbers and work on the insulation of adjoining areas.

The disadvantage of installing a second glazing string is the reduction of space inside the room and not the best interior view. The opening elements of the second glazing circuit must be larger than the first circuit and be at the same level.

At the price of replacing facade glazing and replacing cold glazing with warm glazing, we are one of the best in the Moscow region. Our company replaces cold glazing with warm glazing without changing the appearance of the facade.

Cold glazing of a balcony - why is the design popular?

The desire of the owners of apartments with a balcony to ennoble the loggia, to protect it from prying eyes, rain and wind is completely natural. Now various options are being considered, but one of the most popular is the cold glazing of the balcony.

The choice of the type of glazing of the loggias

First you need to decide on the method that the best way suitable for glazing your balcony. There are two most famous methods - cold, which is considered the most budgetary, and "warm" - using double-glazed windows, additional wall and floor insulation. Which option to choose, you decide, given your own financial capabilities.

But be guided to take into account that the “cold” option is considered the most economical and simple to implement. We will now look at it. To implement this method, it is better to use aluminum, which is characterized by good appearance, ease of use, strength and low weight.

In addition, the use of aluminum aggregates makes it possible to say about the fire safety of a balcony or loggia, in contrast to the sequence of the second materials. And coupled with a small price, the aluminum profile is made good stuff for ennoblement of the loggia.

Advantages and disadvantages of cold glazing

Cold glazing has many advantages, which explains its popularity.
The price of aluminum frames is much lower than wood frames, and even more so than double-glazed windows. As a result, both the acquisition and installation will cost you a very small amount.

Light weight construction

For the most part, frames with sliding doors are left for this type of glazing, which makes it possible to more effectively use the free space on the balcony.

The design execution of the structure is up to you, thanks to which it is possible to choose any coating you like or color design, which will improve the appearance of the balcony. In addition, it is possible to choose any glass that is possible mirror, tinted, shockproof.

Aluminum is an environmentally friendly material that does not emit substances capable of harming the human body. Strength and Durability cannot but rejoice, because aluminum is not subject to corrosion, it can serve for decades - only PVC windows can be compared with them in terms of durability.

But we must not forget that every medal has two sides. Cold glazing of loggias and balconies has its own shortcomings. First of all, this is a low coefficient of thermal insulation, which is why the winter period on the balcony is cold enough.

At low temperatures icing of the iron shutters may appear, and in summer condensation may appear on the windows. In addition, such structures do not provide 100% sound insulation.

Cold glazing options

Frameless cold glazing is divided into a couple of types: aluminum, frameless and plastic. The last option is considered the most economical.

Along with this, the window can be sliding or hinged. If we are talking about sliding option, then in this case the frames will open to the sides, easily sliding on the rollers.

Such a design can significantly increase the required area of ​​\u200b\u200bthe loggia.

It is possible to apply and plastic profiles. Due to the design of this profile, a simple sliding on the rollers is ensured.

By the way, a sliding plastic system retains much more heat than aluminum, while maintaining a small weight along with this. The ease of installation is also pleasing: the frames are inserted into the prepared opening, and the slots are sealed with mounting foam.

There is also a frameless design that does not delay the penetration of sunlight due to the lack of overlap. If you decide to stop at this option, then it is better to buy tempered glass, which is characterized by resistance to impact.

The ease of installation is also pleasing - aluminum profiles are attached to the ceiling, parapet and shelf, and glass sashes are already attached to them.

It is also possible to do this panoramic glazing but this option is the most expensive.

Cold glazing with your own hands

It must be emphasized that the installation window profiles for cold glazing, a fairly simple job. But in order for the design to demonstrate all its own good sides, you need to follow the instructions exactly right.

How to make a cold balcony glazing with your own hands - a step by step diagram

Step 1: Preparing the balcony for work

First of all, go to assess the condition of the loggia, remove all extraneous structures and strengthen the parapet, if necessary. If iron railings are installed on your balcony, it is possible to leave them. The main thing is that the fence is as strong as possible and the top is without a slope.

Otherwise, the railing must be replaced.

In addition, all work related to outer side fences are made before glazing, and to decorative work on ennoblement proceed at the last moment.

Move 2: Measurements

Entrust work better for specialists from which you will order the profiles themselves. And all due to the fact that mathematical accuracy is needed here - the smallest inaccuracy, moreover, by one millimeter will lead to problems during installation.

During work, do not forget to worry about safety - buy a safety belt that can withstand up to 400 kg of weight. The optimal length of the cable is 2.5 meters.

At the end of how all the structural elements will be brought to you, assemble the frame and proceed to the upcoming work.

Step 3: Installing the window

We install the finished structure on the parapet and fix it with self-tapping screws and mounting loops to the plates. We start the visor under the mounting loops and fasten it to the plate with self-tapping screws.

Next, we make an ebb, which must be installed with outside. Along with this, the drain and the visor should be treated with silicone sealant, and the seams between the structure, the top plate and the balcony parapet are sealed with mounting foam.

At the last stage, it is necessary to install the glazing itself with a blind sash and mount the strips (glazing beads), which will ensure a high-quality fit of the glass to the window frame.
