Interior doors, as follows from the name, are designed to separate the premises from each other, to distinguish between the space. However, in addition to aesthetics, they are obliged to provide sufficient sound insulation.

If the strangers from the street prevents you from focusing, it is possible to replace balcony door on a model with increased sound insulation.

Comfortable for man The volume of 30-50 dB is considered, large indicators annoy. The task of windows and doors is to maintain a comfortable noise level in the room, do not miss the loud sounds into the room.

Soundproofing doors is regulated by several regulatory documents: GOST 26602.3-99 "Window and door blocks. The method of determining sound insulation "; Snip II-12-77 "Noise Protection"; SNiP 2.08.01-89 "Residential buildings". So, B. residential rooms Apartments The noise level should be not more than 30 decibels (DB), and, for example, in the shopping halls of the stores and airport expectation halls - no more than 60 dB.

Classification of doors

Different types of doors provide unequal sound insulation. The worst of all the external noise is plastic. Sound and soundproofing properties of doors operating on the principle of rollers, which consist of a set of aluminum (less often wooden or plastic) rails.

Folding interior doors provide, perhaps, the smallest possible sound insulation.

The absorption of sound with shield doors depends largely on their design. Made by old technologies (frame from wooden Reques, sheathed sheet materials Like fiberboard or MDF) poorly absorb sounds, since they have a lot of voids. In some cases, the noise even enhances (the effect of the resonator).

Total sound insulation.Do not be installed in all rooms soundproofing doors. Choose those parts of the room where it is really necessary to protect yourself from noise: bedroom, children's room, office study, music studio ...

Modern technologies for the manufacture of shield doors suggest the filling of the internal volume of cardboard, laid like beeshta - we get the door with best sound insulation. Compared to the wood, the cardboard itself is less elastic and less prone to the transmission of sound.

If you are planning to use the door of the aluminum profile, then it should be remembered for its high sound conductivity. But it takes about 10-15% of the door area, so the contribution of the profile itself into the soundproof properties of the door is small. More importantly filling. If this is a single glass - the achievable sound insulation of the doors will be very low. Another thing is a glass package (located "sandwich" two, three or more glasses with air layers between them) or a sandwich panel, which consists of a foamed material (foam, expanded polystyrene, etc.), lined with plastic. Indicators of the single-chamber glass (from 2 glasses) and the sandwich panel are high enough, and a two-chamber (of 3 glasses) is almost perfect for most rooms in the house.

Soundproofing of the sliding doors are lower than those at least due to the gap, which is inevitably available between shifting canvases.

Good indicators have solid solid wood solid solid. After all, all other things being equal than the harder door, the better protection against noise it provides. However, in any case, sound insulation interior doors Light: The existing noise level is reduced by 10-20 dB.

Very effectively use doors with a double trim. Person S. outside It has protruding edges (folders, or "flood"), which are additionally pressed against the plane of the box, most often in combination with a polymer seal.

Two doors. Interior door with increased soundproof properties can be too expensive. Either in its appearance is embossing out of the overall interior design. In this case, the installation of two is recommended. standard doors With a small air gap between them. Air also acts as a sound insulation.

Protection against noise

If you need to equip home recording studio (which requires silence) or, on the contrary, you like to play on musical instruments And do not want to disturb the neighbors, you will have to pay attention to special doors. Look for labeling on SNIP II-12-77 "Noise Protection". He especially negotiates that specialized sound-insulation doors should absorb at least 26 dB (for example, from the outside, the noise level is 50 dB, and indoors? Not more than 24 dB).
Such doors outwardly do not differ from ordinary. The canvas finish can be any. Special properties are achieved due to internal devicereminiscent of puff pie. The canvas gluits from the fiberboard, chipboard or MDF with layers of mineral wool and sound-absorbing plastic. Number of layers in the door different manufacturers May vary. This technology reduces the noise level by 27-42 dB. In addition to the special design of the canvas, such doors are equipped with special boxes with thresholds.

Examples of interroom doors on a metal box.

There are two types of soundproof boxes: metal and chipboard. They are made in the form of a hollow profile, and to reduce the penetration of sound fill with concrete (for metal box) or mounting foam.

The smaller the gap between the web and the door box, the better. According to the rules, its value must be no more than 1 cm. So that the sounds do not penetrate the slots around the perimeter of the canvas, use the seal - rubber profile hollow cord similar to what is used for plastic windows. It also increases thermal insulation.

Take care that the canvas firmly lightened to platbands: any gap is loss in the soundproof properties of the door.

To reduce noise levels from under the door, clamors are installed. In addition to ordinary wooden, plastic and metal, there are special heat-soundproofing thresholds from combined materials supplemented with brush seal. The threshold is obliged to be in the door of the bathrooms, bathrooms (these are the requirements not only sound, but also waterproofing the room). In all other cases, if you do not want to stumble about it, you can restrict ourselves to installing the inconspicuous sealing to the lower end door.

Soundproofing with your own hands

You can "modify" and the usual door, having put it with one or two sides by the corresponding acoustic materials: Upholstery on a tissue basis, genuine or artificial leather, Dermantine, vinilies in combination with soft filler (batting, sintepon, foam rubber). To increase the fire resistance, the door is recommended to use mineral wool as packing. Improve sound absorption will help and simple covering the door with a wooden rail.

Do not forget about the possibility of installing two doors consistently after each other. The two most ordinary models will give a greater effect than one special soundproofing door.

Remember that only the installation of the appropriate door and the box will not solve the problem of sound insulation. A set of measures to isolation of the entire premises should be carried out: ceiling, walls, floor, windows.

Economy class, medium and premium. Doors of different price categories are characterized by protective characteristics, quality of materials used, "intelligent" abilities.

An ordinary interroom door can unobtrusively support the selected designer solution interior. Or can become the main styrene-forming element in the apartment.

Material, design, finish - these are the main factors affecting the cost of the interior door. What is the differences between models of different price categories?

Modern apartment is always full of sounds and noise, the reason for which can be a lively movement, transportation outside the window or loud music, work household appliances. The use of alone sound insulation and noise absorbing coatings for walls is insufficient, to reduce the level of discomfort, it will be necessary to install sound insulation doors. Select a suitable model is not as simple as in the case of selection of armored or insulated options. Evaluate the soundproofing characteristics of the doors is more difficult than measuring the thickness of the metal or insulation, so you have to count only on common sense and recommendations of specialists.

Requirements for the design of soundproofing doors

The most common misconception of sound insulation characteristics door canvas It concerns the thickness and density of the material, it is believed that the best sound insulation qualities have the most massive and heavy door canvas. This is only partly true, but the high density of the material is not the only condition for good noise absorption.

It is important that the doors of sound insulation interior corresponded to several additional criteria:

• The thickness of the canvas is at least 48-50 mm, the thinner canvas from pressed laminated cardboard, plastic or wood fibers do not possess the necessary sound insulation qualities to reduce noise to the sound comfort of 20-22 dB;
• In the design door box and the soundproofing of the doors should be provided with a fold or a double floor with an additional sound seal that prevents the propagation of the sound wave through the slots and joints in the door frame;
• The lower edge of the sound insulation interior doors is always equipped either guillotine or brush seal. The size of the slot between the floor and the lower edge of the door leaf can reach 10-15 mm, and it is quite difficult to achieve high sound insulation characteristics without a seal;
• Use additional sound insulation overlays on door canopies and loops. Metal is very well spent, so all metal fittings are shielded.

For your information! When choosing soundproofing doors, it is necessary to pay attention to the noise insulation coefficient, the noise absorption standard is 30-35 dB.

The larger in the design of the soundproofing doors, materials with high density and elasticity are used, the worse things are concluded with blocking noise and sounds. For example, the most massive, with the maximum thick door web, the entrance door from the metal has not the best sound insulation characteristics.

Even laying a mineral wool layer inside the framework allows to reduce sound wave pressure to a maximum of 10-12 dB, that is, twice. The reason for the low sound insulation characteristic lies in the fact that in the armored and steel doors there is a large number of Steel ribs and jumpers, which, with any mineral wool layer, will operate a kind of sound bridges that transmit noise inside the room.

Manufacturers go to a more radical step - for the manufacture of input soundproofing doors inner space The steel box was trimmed with a layer of foam polyethylene. As a result, it is possible to improve the parameters of sound insulation protection by 12-15 dB, and when used decorative lining From the MDF, 17-20 dB can be achieved, though, with an increase in door thickness by 3-4 cm.

One of the popular ways to make from ordinary doors soundproofing known for a long time. Ordinary steel door Or made of oak array enough to sew a dense cloth with a foam lining. In addition to improving thermal insulation, it is possible to reduce the noise threshold and achieve sound insulation characteristics at the dual door block level.

Door Box Installation Method

In a large degree, the soundproof properties of the door block with a box and cladding depend on the fastening method.

By radical way to improve the soundproofing indicators can be installed internal wooden doors Facing of a dense laminate with a filler of corrugated paper. You can use any interroom door with a high level of noise and sound insulation resistance.

In theory, you can even install aluminum or plastic door Conventional type, it is not important. The characteristics of the inner canvase are not particularly affecting the ability to resist noise and sound.

In order to double door He possessed high sound insulation characteristics, it is necessary to perform three conditions:

• The size of the air gap in the tambour between the doors should be at least two thickness of the outer door;
• Outdoor I. inner doors necessarily furnish with a sound insulation seal;
• The total door box must be installed using noise insulating materials.

Most of the manufacturers of inlets and interior doors are equipped with door boxes with a set of suspension and anchor mounts. This approach simplifies the installation of the door frame, but often impairs the soundproof characteristics of the door block.

In order for the noise insulating unit to fully resist the noise, a more modern scheme is used. First, the fastening of the wooden or MDF-box to the doorway is performed using silicone traffic jams and plastic dowels. Secondly, before giving the slots in the gap between the box and the wall, the thin strip from the foil isolon is placed, and the Lutka itself is additionally hung around the perimeter on rubber or silicone cord. As a result, any vibrations and shock noises are absorbed at the entrance in the doorway.

The device of sound insulation doors

One of the shortcomings inherent in all types sound-insulating doorsis an enlarged thickness of a wooden or cardboard canvas. Most standard models With increased sound insulation characteristics are made according to the scheme with a three-layer web, a photo.

To obtain high sound insulation characteristics, the door billet is made of three low-density wood-chip panels. The outer surface is facing MDF and covered with wear-resistant laminate with texture imitation valuable breeds Woods. Box make chestnut or mahogany.

For your information! This canvas is called "FDB", produced in Belarus and, according to the manufacturer's statements, is able to provide very high sound insulation characteristics in the air at the level of 37 dB.

The only drawback is the high price of sound insulation door blocks. The cost of one product is more than 600 EUR. High noise insulating characteristics are achieved due to light pulp fibers and air gaps. Truth, high level Soundproofing is achieved by a significant increase in mass, the weight of the door leaf with a thickness of 43 mm reaches 40 kg.

Budget models of sound insulation doors

Cheaper door blocks with increased sound insulation characteristics are manufactured according to the traditional scheme:

• The frame of the door leaf is made of a pine timber;
• Outdoor facing - from MDF panels with a thickness of 8 mm;
• Cellular filler with a curvilinear surface is installed inside the door.

The cells can be filled with polystyrene polystyrene granules, cellulose and mineral fibers. As a result, the insulatory cloth at a cost of about 100 EUR provides noise reduction at 22 dB.

Import analogs of Turkish and Polish production as a backfill use granules from silicate glass and gas-generating agent. Such door canvases, in addition to high sound insulation characteristics, have increased resistance to heat.

Information on the nature of the filler and noise insulation characteristics is necessarily added to the quality certificate on the product.

Doors with special sound insulation characteristics

As interior doors with increased level Insulation can be used by a conventional metal-plastic model with a double-glazed window. Despite the use of aluminum and plastic, materials with low noise insulating qualities, a canvas from two-chamber glass glass It is capable of ensuring noise reduction by 20 dB, and three-chamber by 22-25 dB.

The variant of the metal plastic interroom door block is very convenient for rooms with high sound and temperature load. It may be doornery on the balcony, on open terrace or access to the corridor.

For special occasions when noise level exceeds 50-60 dB, experts recommend ordering the manufacture of door leaf for doors individual project. The doors with high noise protection are performed with the laying of the three-four layers of the rolled soundproof. For example, it may be a noise insulating mat based on pressed silicon fiber. The level of noise insulation is 45 dB, resistance to the open flame front up to 20 minutes. The material does not fit and does not lose characteristics for 20 years of operation.

Conclusion

One of the most effective ways Ensure a high noise insulation characteristic is considered to install on the canvas of the door of the attached panel of foam materials. Thin, only 5 mm material is capable of improving the insulation of a conventional interior unit by 40%. Porous rubber is separated by a polychlorvinyl film with a tree texture, plastic or any other format as a result appearance The door block is practically not changed, and the resistance to noise is enhanced.

Sometimes it happens that next to the apartment is the elevator mine. In this case, the tenants face such a problem as noise from the elevator. It also applies to apartments located on the first floors at home, where big human traffic.

In this case the ideal option It will establish an entrance door with increased sound insulation characteristics. Typically, such doors are characterized by a more serious filling of the canvas and insulation of the box. As such materials can be used:

• mineral Wool Plate (compressed mineral wool);
• polyurethane foam (insecurity);
• mineral wool;
• combined filling (sharing of the above materials).

Also worth paying attention to the thickness of the door canvase and the exterior decoration. The more this indicator, the better. Additionally, protects against the penetration of noise into the room - the use of exterior decoration MDF panel, which can additionally extinguish sound oscillations.

One of the main functions of interroom doors is the protection of the room from the penetration of foreign noise or, on the contrary, the reduction of noise emanating from the room. Therefore, each door can be considered a certain extent soundproofing.

Types of soundproofing doors

door structures depend on the material from which they are made. The thicker and heavier the door canvas, the better it provides it. For example, light blades with voids inside have the smallest sound expire - up to 26 dBA, and wooden interior doors from a disheveled array provide sufficiently high noise insulation - within 32-34 dBA. Worst of all protected from foreign sound folding plastic doors.

If you need elevated anti-network properties, special soundproofing, which offers many manufacturers.

Such canvases are not different from the standard, but have inside the filling of noise insulating materials.
This uses extruded mineral wool, a multilayer chipboard with tubular cavities, a noise protection film and other soundproofing materials.

Where do special soundproof interior doors are required?

For apartments and private houses, as a rule, quite ordinary veneered interior doors made of wood with a seal contour on the box. You can buy such interior doors with a natural or artificial veneer in the online store of Porta Prima Factory. They satisfy sound insulation standards and do not miss the loud sounds into the room.

Interior doors with soundproofed elevated characteristics are usually installed in hotels, hospitals, educational institutions, recording studios and other organizations where a high level of acoustic sound insulation is required.

How to sound the door to the room?

The question of how to sound the interroom door, worries many. To increase the level of sound insulation may be required in cases where you play at home on musical instruments, love to listen to loud music or want to equip the house recording studio. Worse protect the room from outsided sounds than the deaf construction. Therefore, in the bedroom, children's and other rooms, where noise insulation is important, it is better to install doors without glazing. If you want to install a web with glazed and achieve good sound insulation, choose a model with a glass triplex.

For best protection from extraneous noishes door block It is worth complementing the seal and threshold. IN otherwise Through the slots around the perimeter of the canvas in the room will penetrate outsided sounds. Instead of the threshold, you can install a brush seal to the bottom end door.
It is important to remember that solving how to sound the door to the room, you must not forget about the noise insulation of the walls. It is especially necessary if the room is not thick capital walls, but lightweight interior partitions.

If necessary, securely protect against noise, you can improve the noise insulating characteristics of the door leaf with soundproofing materials for doors. The easiest, inexpensive and an effective way - Help the cloth from one or two sides by leather or genuine leather with a thick layer of wattin or synthet board.

And if it allows the thickness of the opening, then you can install a vestibule from two doors. Aerial layer It will extinguish sound waves and reduce the noise level.
