Cheap option soundproof interroom door. Noise insulation of input and interior doors. Materials, solid insulation methods. Remove the keyaches

Multi-storey buildings, where there is simultaneously live or works, not one hundred people, especially needs to install the door with elevated, good noise insulation. And then a few such doors. Thanks to them, the negative impact of noise will be neutralized, and everyone can feel comfortable.

Input and interior wooden soundproofing doors Ostium is very wide.

The most popular places of their installation:

Why it is worth choosing interroom doors with good noise insulation "Ostium"

• Own mounting service. The ability to buy sound insulation doors with installation.

For good productivity and vigorous well-being, a person must be saturated and sometimes rest in silence. And if a large noisy family lives in the house, there are little children, or a novice musician honors his skills, then sometimes it becomes simply impossible to focus and get together with thoughts.

Places where without heightened sound insulation just do not do - this is:

• Bedroom and children's;
• Study;
• Recording studio;
• Creative workshop;
• Hotel room or hotel room.

To solve the problem of superfluous noise, you need to take care of the sound insulation of the rooms, and to start correctly pick up the doors interroom. If they have a sufficient degree of sound insulation, it will help to get closer to the desired level of silence.

One of the options to solve the issue can be noise insulation of interroom doors with their own hands, but it is much easier to initially buy a high-quality product that does not require any alterations.

It is quite logical that the soundproofing of interior doors depends on the quality and thickness of the canvas. Therefore, it is best to deal with the task of noise insulation, the product will cope with a solid or glued massif of the tree, ideally of solid rocks. Because the material itself is expensive, and not available to everyone, other types of interior doors, made of fiberboard, glass, metal, or plastic, received great distribution.

Types of doors and their characteristics

Knowing what noise insulation has each material, interior doors to choose becomes much easier.

Regardless of the material from which the canvas is made, it is important to consider the seal of the door frame throughout the perimeter. Any gaps will contribute to the penetration of sounds inside the room, and vice versa.

Sliding structures

Sliding doors are considered very convenient in terms of ergonomics. They are made of metal or plastic. However, the sound insulation of the adjustable designs of a priori is considered minimal, because there is a small gap between the sash even in the closed position, and the metal, moreover, itself is a good conductor for any sounds.

Selecting the sliding construction for the house, you need to pay attention to the type of opening. There are 2 options: in the first - the sash when opening slide along the wall, and in the second - they hide in a niche inside it. In the latter case, sound insulation is better because it is not forced extra gaps between the wall and sash.

To reduce the level of penetration of sounds when installing sliding interroom doors, you must fill out all possible lumeges in the opening. First of all, the gap between the sash and the wall is used for this plinth. To close the clearance between the ceiling and the doorpace, the carriage is used.

You can also install a sliding design, for the manufacture of which the sandwich panels were used. It has a high level of sound insulation, and can hold up to 50 dB. However, such structures are very heavy and cost a considerable amount of money, so they are more suitable for installation in offices, and not in homes.

Additional measures for sound insulation

To achieve the maximum effect, you can specifically acquire ready-made interior doors with noise insulation made on the principle of sandwich. However, it is not always such a product to fit into the interior of the house. Therefore, it is worth taking care of the strengthening of the already existing design. It is known that due to the correct installation, it is possible to achieve a reduction in noise level by 12 dB.

Consider effective means for increased noise insulation doors:

1. First of all, it is necessary to use a sealant for embelling the slots, and the canvas itself is to sew a special coating from the penetration of noise. To isolate the door with your own hands, you can use sound-absorbing plates, sticking them to the surface with mastic.
2. Installation of doors with a double trim. In such a design, the folds are tightly adjacent to the box, and the rubberized seal is laid throughout the perimeter.
3. Installation of an additional door leaf. In this case, airspace is formed, capable of eliminating excess noise. Such sound insulation doors are rather rare for residential buildings, since in terms of convenience and aesthetics are not entirely attractive. But this is a completely reasonable solution if one room is designed to work at which silence is required and concentration, or vice versa, noises published in the process will interfere with households.
4. To achieve the maximum effect of noise insulation, in addition to gaining the door and the opening should take care of the additional covering of walls and overlaps.

Knowing how to make noise insulation with your own hands, you can solve several tasks at once: save money, not paying for the labor of employees, as well as achieve the desired silence and peace.

Any decorative inserts made of glass, plastic or mirrors reduce the soundproof properties of interroom doors. Choosing a product with a glass insert, you must give preference to a double or triple glass. The greatest sound resistance has a deaf canvas.

Sealing a threshold as another way to achieve silence

To the question of sound insulation of the interior door is to approach comprehensively. After all, even the welfare canvas will not be able to protect against excess noise, if there is a large slot under it.

It was for this reason that there were high thresholds in all homes - they can absorb unnecessary sounds. However, it is inconvenient when there are small children or elderly in the house. Therefore, some manufacturers offer a smart threshold system. It is mounted in the lower part of the door leaf, and when the door is closed, the threshold falls out of the groove, tightly closing the gap. Such a system is able to absorb most of the noise coming from other rooms. When opening, the mechanism works, thanks to which the threshold is hiding in the canvas again.

Interior doors with good sound insulation are the best way without excess costs to provide in the house desired silence after a hard working day. Especially ways to strengthen the sound insulation properties set, starting by buying a special door, and ending with the installation of the appropriate fittings. The main thing is what you need to remember, trying to achieve complete noise insulation that it is necessary to approach the question comprehensively, and, if possible, make extra ceiling and walls.

Reduce the level of noise penetrating the room from the street and from the next room, you can use sound insulation. Increasingly, not only inlets, but also interior doors with noise insulation are installed in apartments and private houses. Soundproofing will help get rid of extraneous noise, which will have a positive effect at the level of residents of the residents at home. It is not necessary to change each door in the apartment on sound insulation, already available designs can be simply upgraded.

The sound absorbing interroom door can have a different design, such structures may differ from each other by opening and manufacturing material, the same applies to the dimensions. Features - the presence of seals both inside and around the perimeter of the entire product, which ensures its good fit to the box.

Despite the external similarity with the familiar structures, the internal filling of the noise absorbing structures has its own characteristics. Door sound insulation can be performed using:

1. corrugated cardboard canvas - the most budget material, losing its properties in the first years of use;
2. minvati - creates a non-combustible plane, but during operation due to the voids formed, it cannot fully determine the noise;
3. a foam plate - along with high sound insulation indicators, has its own minuses, for example, is a rapidly flammable material, which is dangerous to the release of toxic gases;
4. polyurethane foamed - holds noise and outsiders, while meets all the requirements of fire safety.

The level of absorption of sound insulating doors is 27-40 dB, which is determined by the quality and amount of filler. So, a thin and lightweight design is not able to get rid of external noise, so it is worth putting a door with more reliable protection.

Additional ways of sound insulation

As effective ways to improve sound insulation can be applied:

• glass insert;
• stagnation on the door frame of the sealing tape;
• installation of two-layer glass doors with air gap;
• the use of special brushes holding noise.

Interior door structures with a high degree of noise insulation are presented in a large range and can perform a number of additional functions. For example, thresholds in the doorways will help not only reduce the level of external noise, but also to maintain heat indoors. But they can interfere with unhindered movement around the apartment. In this case, the alternative option will be "hidden systems". You can achieve a decrease in the noise level, using:

1. Rubber threshing, which will allow closing the slot under the web, while the opening-closing process will become much easier.
2. The system of "smart threshold" completely isolates the slot under high-quality doors when they are closed, but in the case of opening, the mechanism is activated, which makes the layer of the sealing layer lift to the desired height. Thanks to such a design, drafts will be excluded in the room.

If you wish, you can make good sound insulation and on the old doors, following the scheme below:

• The door box should be sealed with the wall, it will take a sealant for mailing holes.
• Soundproofing sheet process with a special mixture from two sides.
• A dermatin navigated to small carnations is used as a decorative trim of sound insulation doors.
• To close the gap between the web and the box passes the seal.
• Installation of a flexible either "smart" threshold.

Features of designs for interroom doors

The basis of noise insulating door structures is taken by plastic, metal, glass and Fiberboard stoves. Wood and similar materials are suitable for swing doors, and plastic and metal - for sliding products. With the help of the latest models it is impossible to fully protect the room from penetrating sounds.

A similar quality is offered doors to an apartment with a frame with a casing of MDF and chipboard. This manufacturing technology is characterized to a greater extent for the structures of the old sample, now the models are equipped with a cardboard insert with filling in the form of honeycomb, which due to its elasticity hold out a foreign noise.

A high degree of sound insulation do the doors made from a natural tree.

Decorative inserts made of glass and mirrors reduce the soundproofing level, so the optimal glazing is considered up to 20% of the total area of \u200b\u200bthe canvas. To improve protection indicators, it is better to establish a double or triple design. Solid wood species can reduce the penetration of noise about 20 dB. Even if there are no noise-absorbing materials in the design, wooden doors will be considered sound insulation.

The achievement of complete sound insulation is possible in the case of a minimum interval from the box to the canvas. As an example, structures can serve as a double floor with a protruding groove and a layer of polymer seal.

Pros and cons

Holding sounds is not the only purpose of noise insulating products, they are endowed by a number of related functions:

1. Prevent corrosion of structures. Due to the insulating filling, the interior doors are protected from reproduction of mold and other pathogens of microorganisms.
2. Strengthen design.
3. Thermal insulation of the room. Almost all sound insulation fillers retain heat, closing cold bridges and preventing the formation of drafts.

Installing such a door will solve several tasks at the same time.

How to choose

When choosing doors, it is important to pay attention to the following characteristics:

• material;
• structure of the door leaf;
• facing elements;
• the thickness of the design.

The best material for the manufacture of silent interior doors is a tree. So, the wooden array of interroom door leaf is able to drown out the external sounds of 10-15 dB. When using panels with the inner cavity, the opposite effect is possible - the resonance of sounds will begin, which will lead to an increase in the penetration of noise into the room.

To solve this problem, it is advisable to apply special fillers. The noise insulation of plastic or metal structures increases in a similar way, the purpose of which does not involve the provision of silence.

As an additional protective agent, you can apply a metal foil with a soft lining. Such a sandwich reflects the waves of sound and does not give them penetrating inside.

If the installation of metal doors is a prerequisite, then noise insulation is performed not only by the internal filler, but also by external facing for the aesthetic product type. It is also attractive to finish from a tree of any variety - an array, MDF, lining. Often the masters perform an artificial leather upholstery, which will look good on the background of the interior and will reduce the noise level.

Features of choice by the method of opening

The level of protection against noise depends on the type of door design. The plastic door is considered the very bad soundproofing structure. Do not cope with this task of door-shutters with aluminum (wooden, plastic) rails. It is also not necessary to rely on the sliding, the harmonica is not able to absorb the sound.

How to make it yourself

It is possible to make high-quality noise insulation of the interior door yourself, for this it is trimmed with acoustic materials stuffed with a filler so that there are no cracks and gaps. All work is simply carried out, you only need to follow the proposed instructions:

1. Material for upholstery. You can use natural skin, dermatin, vinyl and other similar means. Special plates with adhesive layer are well suited, which makes it easy to stick them on the canvas.
2. Filler: batting, sintepon, foam rubber. For the purpose of fire safety, experts recommend using mineral wool, which absorbs outsiders and does not support burning.
3. All slots in the box and walls are flooded with sealant.
4. The upholstery with a soft noise absorbing gasket is nailed for one or both parts of the canvas.
5. Sticking the sealer. The material should not get into the gap, it serves to close it. From the canvas to the sealing tape, the minimum distance should be maintained - no more than 10 mm.
6. Installation of the neck or seal to the bottom of the doors.

Thus, the soundproofing of interior doors will help with their own hands to get rid of outsided sounds in the room. However, the doors will not be able to provide complete silence, for this it will be necessary to additionally work with walls, ceiling, floor and windows.

Oh, these loud neighbors on the stairwell and their barking dogs. This clanging elevator. And at home you want silence and tranquility. What to do? Of course, the walls in the house are no longer changed, and serious investments will be needed to be seen. The answer is one - install the entrance door with good sound insulation. How to choose it - read in the article.

When do you need a door with enhanced sound insulation?

Many residents of apartment buildings are familiar with the problem of lack of silence. But even if the house is good sound insulation, and only the loudest sounds (trills drills and beating the neighbor's dishes about the floor), the entrance door can be a vulnerable place.

We must think about the entrance door with enhanced insulation, if:

• you live near the crashing elevator
• or on the first floor, where every day there are crowds and orava to night
• or you just lucky with neighbors along the staircase, and they always joyfully notify you about their existence.

Another important point - you yourself do not want the neighbors to hear you. Maybe you like to hum in the hallway, but not yet ready to open this talent to the world. In any case, the door with noise isolation will provide you with confidentiality and comfort.

What is sound insulation? Types of noise

And what is generally "sound insulation"? To answer this question, you need to plunge into physics and understand how the sound works.

Sound is elastic waves that apply to a gaseous, liquid, solid medium. The sound wave hits the surface of the subject, partially reflected from it, and partially passes through.

Soundproofing is the ability of the structure to loosen the sound passing through it as outward and inside.

There is also a concept of sound absorption. This is the ability of the material to absorb sound oscillations and dispel them in their own internal structure, without passing on the other side.

At the same time, it should be understood that the door will not protect against all types of noise. Noises are divided into 2 types: shock and air.

Impact noises are the favorite sounds of the perforator, the movement of the furniture, the football of the legs. The door with good noise insulation can only weaken them, but not to remove completely.

Air noises are screams, loud laughter, barking dogs, crying children, music. Those sounds that apply only by air and do not come into contact with surfaces of objects. Such noises the door with reinforced sound insulation will not miss the apartment. GOST 31173-2016 regulates the ability of the door design to reduce the air noise.

According to the degree of sound insulation, the input steel doors are divided into 3 classes. The inlet steel door should have an indicator for sound insulation of at least 20 decibels. The highest class of sound insulation implies the performance of the indicator at the level of 26-31 decibels. Choose the door, the indicators of which are superior to the highest first class according to GOSE or surpasses it.

What does the door sound insulation?

The entrance door is a complex design in which each element performs its function. Soundproofing doors depends on:

• the thickness of the canvas doors
• filling the canvas and door box
• the tightness of the gaps between the canvas and the door box.

The thickness of the door canvas

The thickness of the door leaf should be at least 80 mm. This indicator will ensure not only the strength of the structure, but also will make it fill in the web with a multi-layer filler for good sound insulation.

Filling the door canvase

Various porous materials are placed in the door canvas. However, the concepts of "soundproofing material" does not exist. Soundproofing only the door.

When filling, it is necessary to observe the principle of multi-layered and diversity. For reinforced noise insulation, there is not enough single thick layer of material, as not enough and seven layers of corrugated cardboard.

It is important to combine different structures and thickness of fillers and the number of layers. For reliable sound insulation, we recommend choosing a door with a minimum of four layers of high-quality fillers.

Why? The sound wave passes through the layers and fades them. Each layer takes part of the sound on itself, and the part gives the following layer.

Types of fillers

For insulation doors, various porous materials are used, which differ in density and thickness.

Hard foamed polyurethane (PPU)

Polyurethane foam (PPU) is a synthetic substance of a cellular structure from a group of gas-filled plastics. PPU consists of inert gas for more than 85%. It is solid materials that are well carried out, and the air hea is the best sound insulators. In the composition of the polyurentan, only 15% of the hard matter remains, so it reduces the noise.

Refuture myths. It is believed that the PPU is a short-lived material and can crumble because it is compared with the mounting foam. This is possible when exposed to ultraviolet rays. However, rigid foamed polyurethane does not interact directly with sunlight, as it is inside the canvas. So, serves a long time - at least 50 years.

Mineral plate is a fibrous insulating material obtained from silicate melts of mountain and volcanic rocks.

High sound insulation and high density. Differs on properties from mineral wool. Mineral wool - cheaper and less durable material. As a rule, it is not made of stone rocks, but from glass and has a light yellow color. In fact, it is familiar to all glass gamble.

For reinforced noise insulation, choose the door filled with a mineral plate with a density of 70 kg / m3.

Foam concrete - cellular concrete having a porous structure due to closed pores throughout the volume. The material is obtained by hardening the solution consisting of cement, sand, water and a foaming agent.

The Torex plant has a patented refrigerated technology technology. This is a combination of foam concrete with polyurethane foam and reinforcing metal grille. This solution gives the door at the same time an increase in sound insulation and strength of the structure.

Isolon and foil foam

Isolon - foamed polyethylene. It consists of the smallest cells (pores) of a closed type.

Fungalized foam, in contrast to the isolon, is covered with aluminum foil from one or both sides.

These materials have high sound insulation indicators and are moisture-resistant. And often applies as "oshszyumki" when installing floor coatings.

Noise insulation material, which is used as an additional layer. Does not take the design and effectively reduces the vibrations.

"Automotive" materials

These materials are used for car sound insulation. This is STP GB and car felt.

STP GB is an elastic vibration-absorbing material based on hermetic mastic coated with aluminum foil.

Automotive (acoustic) felt - dense synthetic nonwoven material with a porous layered structure. 100% consists of artificial, synthetic polyester fibers.

STP GB and automotive felt are effective modern materials that provide high noise insulation of the door, and also absorb the vibrations. In the entrance doors with good noise insulation, manufacturers use the combination of these fillers to achieve maximum sound insulation indicators exceeding the GOST indicators.

MDF panels

The MDF panel is not only an elegant design solution, but also an additional layer of soundproofing material that prevents the penetration of noise into the room.

The combination of these fillers and the multi-layer filling of the door is that it provides the doors reinforced sound insulation.

The tightness of the gaps between the canvas and the door box

Tightness folds from two factors:

• the presence and quality of the seals around the perimeter of the canvas
• proper installation door in the opening.

Seals

Seals are installed around the perimeter of the canvas and box for dense door fit. Quality seals are rubber and magnetic. Magnetic seals in combination with rubber gives greater tightness.

And now again to the myths and the legends of the door world. There is a common opinion with which you may encounter online articles or stores, which is important only quantity Seal contours.

This is not quite so and that's why. If you just "roll out" close seals, the desired result is not achieved. Between the contours should be space for efficient sound insulation. The optimal number of seals in the doors with enhanced sound insulation is from two to four contours.

Another important factor. Choose the door from the manufacturer who orders seals made specifically for entrance doors. Some manufacturers establish universal seals used in refrigerators, windows and in general, anywhere.

1. Increase the mass of the door

The door must be massive. Massive is 30-40 kg / m 2. Suitable either steel doors, or wooden, composed of an array of wood, you can use chipboard, OSB or MDF.

2. Eliminate the slit

The door frame must be sealing along the contour of the gun. The threshold is required: stationary or (falling out when the door is closed):

For compaction, it is best to use a D-shaped rubber gasket. Remember than more tightness, the higher the sound insulation of the door.

3. We draw tambour

If you need to achieve high sound insulation, you can use two doors, i.e. Establish an entrance group in the form of a tambour. The larger the distance between the do the above sound insulation. Sound-absorbing materials should be placed on the inner surfaces.

4. Remove the lock wells

They skip the sound well and, if possible, avoid them.

5. Reduce clearances

The gaps between the door frame and the opening wall should not be very large (no more than 10-20 mm).

Example of interior door with sound insulation:

The room has a column and the noise signal is turned on with a 90 dB volume at a meter from the source. The soundproofing of the door was obtained by the difference in the noise level inside the room and outside with the door closed.

According to the test results, R W ≈38 dB soundproofed (with swearings and platbands will be even quieter)!
