Soundproofing of buildings is of great importance for human health and comfort. In particular, noise in the workplace not only affects the -working climate-, but also significantly limits the ability to concentrate and perceive. Soundproof doors manufactured by MGK-Group provide optimal protection at high noise levels.
They provide pleasant acoustics, reduce noise pollution, increase work efficiency and protect health. Thanks to the special design of the door leaf, certified insulation material and special seals, the doors provide optimal sound insulation values. When used as a multi-purpose door, a combination of fire and smoke protection, thermal insulation properties is additionally possible if required. Since ideal conditions do not exist in reality, 5 dB must be subtracted from the tested sound insulation value. To suit your individual noise sources, you can choose from a wide range of protection from 28dB to 45dB to suit any building situation. Spheres of use of soundproof doors: doors for hotels; doors for offices, meeting rooms; doors for recording studios.
Soundproof doors and fire doors are similar in execution. The color scheme and various textures of finishing materials used in the manufacture of soundproof and fire doors allow us to solve the most sophisticated design solutions. The standard leaf thickness is from 40 to 59 mm, and the dimensions of the door allow it to be built into a variety of openings.
We produce soundproof doors with the following types of coatings:
- Finishing film
If it is not possible to install a wooden threshold in soundproof doors, we can offer you automatic soundproof thresholds up to 48 db manufactured by "PLANET" built into the door leaf.
Since various boards are used in the manufacture of soundproof and fireproof doors, the doors can only be made smooth, with an overlaid infill and with a milled infill. Cloths can be both without a fold (a quarter) and a fold.

Soundproofing an apartment is the most important issue that every inhabitant of an apartment building probably thinks about. And if the soundproofing of walls and ceilings does not raise questions, since many articles have already been written about it, then today we will talk about how to make soundproofing doors with our own hands, and below we will give a video of this process.
is a very important issue that worries many homeowners. It is especially relevant for residents of Soviet-style high-rise buildings, because during the construction of these houses, little attention was paid to protecting apartments from extraneous noise. As a result, tiny landings, thin walls and plywood doors left absolutely no chance for a quiet life. There are several ways to change the situation and ensure a comfortable existence. The first is to replace the door with a metal-plastic one, consisting of several layers, one of which is a high-quality sound insulator of varying degrees of conductivity.
The following materials can be used inside modern entrance doors:
- Foamed polyurethane. It is a good sound insulator, it does not let extraneous noise into the room and is characterized by high resistance to fire. The material closely adheres to the door leaf from the inside and does not let in sounds.
- Styrofoam is characterized by a low specific gravity, it protects well from noise, but in case of fire it causes severe smoke.
Advice! Experts advise, if possible, to refuse to buy entrance doors with an internal foam sound insulator, since this material is characterized by a low level of fire safety.
- Mineral wool. Quite with good fire resistance, however, during operation, it absorbs moisture and sags under its weight.
- Corrugated cardboard. This is the cheapest option, however, its soundproofing characteristics leave much to be desired.
Modern models of metal-plastic entrance doors are additionally equipped with special sills and sealing contours, thanks to which the leaf fits snugly against the door frame without any gaps. Expensive models are sheathed from the inside with a layer of artificial leather, which is also a good sound insulator.
Types of soundproofing for entrance doors and methods for its implementation
If it is impossible to replace the doors with better ones, you can make the soundproofing of the old door leaf and door frame yourself. Perform it in several ways.
Arrangement of the vestibule
It's no secret that metal is a poor sound insulator, while the characteristics of wood in this regard are much higher. Therefore, our compatriots often install a double door. The first of them is external, in most cases it is made of reliable and durable metal and protects against the penetration of uninvited guests. The second - internal - is made of wood and is an excellent barrier to all sorts of noises and smells. An air gap is formed between the doors, which acts as a heater.
Each of you has probably seen more than once that a layer of sealant is glued around the entire perimeter of the door frame in new doors. If there are several such contour layers, they are able to provide truly high-quality sound insulation.
There are several types of soundproofing circuits on the modern market:
- silicone - mounted in a slot on the door frame or canvas using a plastic rib.
- Foam rubber contour. It has an adhesive base, thanks to which it is easy to perform independent soundproofing of the front door.
- The magnetic circuit provides a hermetic fit of the doors and, as a result, their good sound insulation.
Advice! Using a soundproof circuit is one of the most affordable and effective ways to soundproof an entrance door, which you can do yourself.
Do-it-yourself soundproofing with upholstery
Not so long ago, a very effective way of soundproofing the front door with the help of its outer finish with a thick layer of batting was especially popular in the vastness of our Motherland. Some craftsmen generally managed to upholster the door leaf with an old blanket, and cover it with leatherette on top. Even now, when asked about which sound insulation is better, they declare with confidence: the one that is made with their own hands and with the help of a thick wadded blanket!
Today, isolon and synthetic winterizer are used as a sound insulator for door upholstery. They are laid in several layers, and covered with leatherette or artificial leather on top - to give the canvas a beautiful appearance.
As alternative options for soundproofing entrance doors, one can consider mounting decorative panels on the canvas, installing rubber thresholds, sealing the gaps that form between the door frame and the walls with concrete mortar.
Interior doors are much thinner in texture than entrance doors, which is not surprising, because they are designed to carve up the space inside an apartment or house. However, this does not mean at all that the issue of sound insulation of such structures is not relevant. If we take a large family, one part of which dreams of a daytime sleep, and the second part dreams of watching a football match with all the ensuing circumstances, it becomes clear that good soundproofing of interior doors is indispensable. But before talking about its types and methods of implementation, let's consider the materials from which the door leaf is made today. So, as materials for doors installed inside the apartment, use:
- natural wood;
- Fiberboard (the most budget option);
- metal;
- plastic;
- mirror and glass plates.
The most popular doors are made of wood-fiber boards (DVP). Their canvas can be solid and hollow, with or without filler, with inserts of glass and other materials. The lowest degree of sound insulation is characterized by doors with glass inserts and hollow door leafs, which in general are a kind of resonators.
Speaking about what material is better for soundproofing interior doors, it should be noted a solid array of natural wood. But through plastic and glass doors, sounds and noises freely penetrate from one room to another.
Today on sale you can find high-quality soundproof doors, which are made according to the principle of a sandwich. If they are mounted in special boxes with automatic rubber thresholds, the sound absorption level can reach 26 dB. True, such a decision is not always justified, because the appearance of such structures is not particularly aesthetically attractive.
Independent soundproofing of interior doors
Professionals assure: if the door between separate rooms within the same apartment is installed correctly, the noise level can be reduced by at least 12 dB. If you also use the best materials for sound insulation, you can even more noticeably reduce the noise level.
Advice! Installing interior doors in accordance with technical standards reduces the noise level by 12 dB.
Stages of soundproofing interior doors
- Seal all the cracks between the wall and the door frame (for this you need to use a sealant).
- Sheathing of the door leaf on the side from which extraneous noise enters the room. The role of the filler in this case can be played by a synthetic winterizer, foam rubber, mineral wool, batting. Leatherette, artificial leather and other materials are used as sheathing. Often, door leafs are sheathed with special sound-absorbing plates, which are glued with mastic and covered with decorative material.
- Sticking a seal around the perimeter of the door leaf, for this you can take a regular profile hollow rubber cord.
Advice! The gap formed between the door leaf and the frame should not be more than 1 cm.
- Installation of a threshold that will prevent the penetration of noise through the gap under the door. Today in stores you can find sills made of a wide variety of materials with a sound-absorbing effect.
Tips for self-soundproofing doors in an apartment or house
If you want to install beautiful interior doors with glass inserts in the apartment, which, by the way, do not differ in special sound insulation, it is better to give preference to models with special soundproof double-glazed windows.
Given the demand for doors with high-quality sound insulation, today domestic manufacturers offer a whole range of solutions - these are panel doors made of solid wood.
Doors with a polymer seal or special folds, the use of cellular cardboard as a filler for voids in the door leaf, and for doors with a PVC frame - the use of a two- or three-chamber double-glazed window, which excludes the free penetration of sound into a closed room.
Reviews of soundproof doors in the Revado store
Simchenko Anton Fedorovich:
We have a big house, there are always many grandchildren. Children often make noise. And my wife and I want peace and quiet. We ordered soundproof interior doors from you. We did not even expect that our room would become really quiet. I also liked the design - calm and discreet, but at the same time original. I want to thank. Now if we order more doors, then only from you.
Kletchenko Inna:
I was looking for soundproof interior doors for my parents for almost a month. Dad rejected several options. And only yours he liked. He said he couldn't do better himself. I was even surprised when I heard such praise from his lips. Cover, locks, handles - we all liked everything. Delivery and installation was also very fast. I will soon do repairs myself, I will not even look anywhere else. I will definitely order from you again.
Interior doors are needed in order to delimit the space, but they must also prevent the penetration of excess noise. Rooms such as children's rooms, bedrooms, music rooms, workshops require doors with good sound insulation. In this article, you will learn how to choose soundproof doors, taking into account customer reviews.
Structural features of doors for sound insulation
Interior doors with increased sound insulation are made of fiberboard, plastic, metal or glass. made of wood and its analogues, and sliding - plastic or metal. But the latter have the lowest sound insulation properties. Models made using panel technology have poor sound insulation performance, when the frame is sheathed with MDF or chipboard panels, because. inside such a "sandwich" a resonating space is created. But old models were made in this way, modern panel doors have a cardboard partition made according to the honeycomb principle. They are more resilient than wood, so they transmit less sound.
Attention! Doors, which are subject to increased requirements for sound absorption, are made of solid wood.
Glass or mirror inserts also impair sound insulation. Experts advise making the glazing area up to 20%. Otherwise, it is necessary to make double, and preferably triple inserts.
Hardwood paneled doors reduce noise levels by up to 20 dB.
Advice! The more massive and heavier the door, the worse it transmits sound.
Good sound insulation is achieved when the distance between the door frame and the leaf is minimal. According to this principle, doors with a double porch are designed, along the edge of which there is a protruding groove with a polymer seal, which allows it to be pressed tightly against the frame without leaving gaps.
Many companies offer custom-made doors using special technology. Visually, they do not differ from conventional interior counterparts, but inside they consist of layers of sound insulator and chipboard glued together.
Good protection against noise is provided by plastic doors with a multi-chamber layer of double-glazed windows. The more cameras, the less sound gets into the room. Such doors are often installed in offices or public places, but they can also be installed in an apartment, choosing the right interior.
Attention! To further enhance the effect of sound insulation, purchase a special metal box, filled with concrete or foam from the inside, as a set for the doors. It provides a minimum gap with the door frame, less than 1 mm.
Fillers for noise insulation
When choosing doors, pay attention to soundproofing material. The most effective are the following:
- corrugated cardboard with a layer in the form of honeycombs is a cheap material, but after some time it loses its structure, forming gaps, due to which the sound insulation deteriorates;
- basalt mineral wool - does not burn, but gradually settles and then voids appear that let noise through;
- polystyrene - has good sound-absorbing properties, but is fire hazardous, while toxic gas is released that is dangerous to human life;
- polyurethane foam is a low-combustible material that tightly covers all voids, preventing sound from penetrating.
Additional methods of soundproofing
The presence of thresholds in the door provides additional heat and sound insulation, but it is inconvenient to step over them if there are elderly people or small children in the house. However, for this, “hidden” structures are installed:
- A flexible sill made of rubber reduces the gap between the floor and the door leaf, provides easy closing / opening of the door.
- - this is a sealant that is attached to the door leaf, when the door is opened it rises, and when it is closed it falls, leaving no gaps. In addition, such a system protects the room from drafts.
You can also "finish" the old doors. To do this, you just need to sheathe them with a layer of sound insulator, according to the following scheme:
- We close up all the cracks with sealants between the wall and the door frame.
- We glue the soundproofing material with a special mastic on both sides.
- We decorate the door with leatherette, hammering it with carnations along all sides.
- We close the gap between the frame and the door leaf, pasting it around the perimeter with a sealant.
- We set a flexible or "smart" threshold.
In conclusion, I would like to add that the installation of only soundproof doors will not completely eliminate extraneous noise. It is necessary to approach comprehensively: to insulate walls, ceilings, flooring, install plastic double-glazed windows.

Listen to articleAh, those loud stairwell neighbors and their barking dogs. That clanking elevator. And at home you want peace and quiet. What to do? Of course, the walls in the house can no longer be changed, and serious investments will be required to sheathe them. There is only one answer - to install an entrance door with good sound insulation. How to choose it - read the article.
When do you need a door with reinforced sound insulation?
Many residents of apartment buildings are familiar with the problem of lack of silence. But even if the house has good sound insulation, and only the loudest sounds are heard (trilling drills and beating neighbor's dishes on the floor), the front door can become a weak spot.
It is necessary to think about the front door with enhanced sound insulation if:
- you live next to a rattling elevator
- or on the ground floor, where crowds and mobs go every day from morning to night
- or you just got lucky with your neighbors in the stairwell, and they always happily inform you of their existence.
Another important point - you yourself do not want the neighbors to hear you. Maybe you love to sing in the hallway, but are not yet ready to reveal this talent to the world. In any case, a soundproof door will provide you with privacy and comfort.
What is soundproofing? Types of noise
What is “soundproofing” anyway? To answer this question, you need to delve a little into physics and understand how sound works.
Sound is elastic waves that propagate in a gaseous, liquid, solid medium. A sound wave hits the surface of an object, is partially reflected from it, and partially passes through.
Soundproofing, on the other hand, is the ability of a structure to attenuate sound passing through it, both outward and inward.
There is also the concept of sound absorption. This is the ability of a material to absorb sound vibrations and scatter them in its own internal structure without letting it through to the other side.
At the same time, you need to understand 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 a perforator, the movement of furniture, the clatter of feet. A door with good noise insulation can only weaken them, but not completely remove them.
Airborne noises are screams, loud laughter, barking dogs, crying children, music. Those sounds that propagate only through the air and do not come into contact with the surfaces of objects. A door with reinforced sound insulation will not let such noises into the apartment. GOST 31173-2016 regulates the ability of the door structure to reduce precisely airborne noise.
According to the degree of sound insulation, entrance steel doors are divided into 3 classes. The entrance steel door must have a sound insulation index 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 a door whose performance exceeds or exceeds the highest first class according to GOST.
What makes a door soundproof?
The front door is a complex structure in which each element performs its function. The sound insulation of a door depends on:
- door leaf thickness
- filling the door leaf and frame
- tightness of the gaps between the leaf and the door frame.
Door leaf thickness
The thickness of the door leaf must be at least 80 mm. Such an indicator will ensure not only the strength of the structure, but also allow you to fill the canvas with a multilayer filler for good sound insulation.
Filling the door leaf
Various porous materials are placed in the door leaf. However, the concept of "soundproofing material" does not exist. Only the door is soundproof.
When filling out, you must follow the principle of layering and diversity. For enhanced sound insulation, one thick layer of material is not enough, just as seven layers of corrugated cardboard are not enough.
It is important to combine fillers of different structure and thickness and the number of layers. For reliable sound insulation, we recommend choosing a door with at least four layers of high-quality fillers.
Why? The sound wave passes through the layers and attenuates in them. Each layer takes part of the sound onto itself, and gives part to the next layer.
Types of fillers
To insulate doors, various porous materials are used, which differ in density and thickness.
Rigid polyurethane foam (PPU)
Polyurethane foam (PPU) is a synthetic substance with a cellular structure from the group of gas-filled plastics. PPU consists of inert gas by more than 85%. It is solid materials that conduct sound well, and air and gas are the best sound insulators. Only 15% of the rigid substance remains in the composition of polyurethane foam, so it reduces noise.
We debunk the myths. There is an opinion that polyurethane foam is a short-lived material and can crumble, as it is compared with polyurethane foam. This is possible when exposed to ultraviolet rays. However, rigid polyurethane foam does not interact directly with sunlight, as it is located inside the web. So, it serves for a long time - at least 50 years.
Mineral board is a fibrous insulating material obtained from silicate melts of rocks and volcanic rocks.
It has high sound insulation and high density. It differs in properties from mineral wool. Mineral wool is a cheaper and less durable material. As a rule, it is not made of stone, but of glass and has a light yellow color. In fact, this is a glass wool familiar to everyone.
For enhanced sound insulation, choose a door filled with mineral slabs with a density of 70 kg / m3 or more.
Foam concrete - cellular concrete having a porous structure due to closed pores throughout the volume. The material is obtained as a result of hardening of a solution consisting of cement, sand, water and a foaming agent.
The Torex plant has a patented Reinforced thermal concrete technology. This is a combination of foam concrete with polyurethane foam and a reinforcing metal grating. This solution gives the door at the same time increased sound insulation and structural strength.
Izolon and foil penofol
Isolon - foamed polyethylene. It consists of the smallest cells (pores) of a closed type.
Foil penofol, unlike isolon, is covered with aluminum foil on one or both sides.
These materials have high rates of sound insulation and are moisture resistant. They are often used as "noiseless" when installing floor coverings.
Soundproofing material, which is used as an additional layer. It does not weigh down the structure and effectively reduces vibration noise.
“Automotive” materials
These materials are used for soundproofing cars. These are STP GB and car felt.
STP GB is an elastic vibration-absorbing material based on sealed mastic, covered with aluminum foil.
Automotive (acoustic) felt is a dense synthetic non-woven material with a porous-layered structure. 100% man-made, synthetic polyester fibres.
STP GB and car felt are effective modern materials that provide high noise insulation of the door, as well as absorb vibration noise. In entrance doors with good sound insulation, manufacturers use a combination of these fillers to achieve maximum sound insulation performance that exceeds GOST.
MDF panels
MDF panel is not only an elegant design solution, but also an additional layer of soundproofing material that prevents noise from entering the room.
The combination of these fillers and the multi-layer filling of the door is what provides the door with enhanced sound insulation.
Tightness of gaps between leaf and door frame
Tightness consists of two factors:
- the presence and quality of seals around the perimeter of the canvas
- correct installation of the door in the opening.
Seals
Seals are installed along the perimeter of the leaf and the box for a snug fit of the door. High-quality seals are rubber and magnetic. Magnetic seals combined with rubber seals provide greater tightness.
And now back to the myths and legends of the door world. There is a common opinion that you may encounter in online articles or stores, which is only important number seal contours.
This is not entirely true, and here's why. If you simply “stick” seven seals closely, you will not achieve the desired result. There must be space between the contours for effective soundproofing. The optimal number of seals in doors with enhanced sound insulation is from two to four circuits.
Another important factor. Choose a door from a manufacturer that orders seals made specifically for front doors. Some manufacturers install universal seals that are used in refrigerators, windows, and in general, anywhere.
