How to achieve silence in an apartment: improving the sound insulation of a door with your own hands. Choosing a soundproofing interior door for home and office Additional methods of sound insulation

Sound insulation of buildings has great importance for human health and comfort. Especially noise in the workplace not only affects the -working climate- but also significantly limits the ability to concentrate and perceive. At high level noise, soundproofing doors produced by MGK-Group provide optimal protection.

They provide pleasant acoustics, reduce noise pollution, increase work efficiency and protect health. Thanks to the special design door leaf, certified insulating material and special door seals provide optimal sound insulation values. When used as a multi-purpose door, if necessary, a combination of fire and smoke protection and thermal insulation properties is also possible. Because in reality ideal conditions does not happen, 5 dB should be subtracted from the tested sound insulation value. To individually match the characteristics of noise sources, you can choose from a wide range of protection from 28 dB to 45 dB for any construction situation. Areas 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 design. Color range and various textures finishing materials used in the manufacture of soundproof and fireproof doors, allow us to solve the most sophisticated design solutions. Standard thickness the blades range from 40 to 59 mm, and the dimensions of the door allow it to be built into a wide variety of openings.

We produce soundproof doors with the following types coatings:

Finishing film

If you can't deliver wooden threshold in soundproof doors, we can offer you automatic soundproofing thresholds up to 48 db produced by "PLANET", built into the door leaf.

Since in the manufacture of soundproofing and fireproof doors it is used various slabs, doors can only be made smooth, with an overlay panel and with a milled panel. Canvases can be either without a rebate (quarters) or with a rebate.

Interior doors are needed to delimit space, but they should also prevent the penetration of excess noise. Rooms such as a nursery, bedroom, 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. they are made of wood and its analogues, and sliding ones are made of plastic or metal. But the latter have the lowest sound insulation properties. Models made using panel technology, when the frame is covered with MDF or chipboard panels, have poor sound insulation properties, because A resonating space is created inside such a “sandwich”. But in this way old models were made, modern ones panel doors have a cardboard partition made according to the honeycomb principle. They are more elastic than wood, so they transmit less sound.

Attention! Doors that are subject to increased sound absorption requirements are made from solid wood.

Glass or mirror inserts also impair sound insulation. Experts advise making the glazing area up to 20%. Otherwise, you need to make double, or better yet, triple inserts.
Paneled wooden doors from hard rocks 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 door frame and the sash will be minimal. Doors with a double rebate are designed using this principle, along the edge of which there is a protruding groove with polymer seal, allowing you to press tightly to the box without leaving gaps.

Many companies offer to make custom doors using special technology. Visually, they do not differ from ordinary interior analogues, but inside they consist of layers of sound insulation and chipboard glued together.

Provides good noise protection plastic doors with a multi-chamber layer of glass. The greater the number of cameras, the less sound penetrates the room. Such doors are often installed in offices or in public places, but they can also be installed in an apartment by choosing the right interior.

Attention! To further enhance the sound insulation effect, purchase a special metal frame for the doors, filled with concrete or concrete from the inside. polyurethane foam. It provides a minimum gap with the door frame, less than 1 mm.

Fillers for sound insulation

When choosing doors, pay attention to soundproofing material. The most effective are the following:

corrugated cardboard with a honeycomb-shaped layer is a cheap material, but after some time it loses its structure, forming cracks, which causes sound insulation to deteriorate;
basalt mineral wool– does not burn, but gradually settles and then voids appear that allow noise to pass through;

polystyrene foam - has good sound-absorbing properties, but is fire hazardous, and produces toxic gas that is dangerous to human life;
foamed polyurethane is a low-flammable material that tightly covers all voids, preventing the penetration of sound.

Additional methods of sound insulation

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 purpose “hidden” structures are installed:

A flexible threshold made of rubber reduces the gap between the floor and the door leaf and ensures easy closing/opening of the door.
- this is a seal that is attached to the door leaf; when the door is opened, it rises, and when closed, it lowers, leaving no gaps. In addition, such a system protects the room from drafts.

You can also “modify” old doors. To do this, you just need to sheathe them with a layer of sound insulation, according to the following scheme:

We seal all the cracks with sealants between the wall and the door frame.
Glue with special mastic soundproofing material, at both sides.
We decorate the door with leatherette, hammering it with nails 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 installing only soundproof doors will not completely eliminate extraneous noise. You need to take a comprehensive approach: insulate walls, ceilings, flooring, install plastic double-glazed windows.

By installing a new metal entrance door into an apartment, each owner strives to turn his home into an impregnable fortress not only against robbers and thieves, but also noise from the entrance and landing through the doorway. Manufacturers of doors, first of all, strive to insulate them, ignoring the fact that not all types of filler can soundproof an apartment well. In this regard, noise insulation of the input is often required. metal door.

Let us immediately note that many consumers, installing expensive doors from famous manufacturers(Russian, Belarusian and Polish companies) mistakenly believe that the noise problem is solved automatically.

In practice, even footsteps can be heard in the apartment. landing. And it’s not a matter of poor sound insulation of the door - it meets the standards and blocks 30-40 dB of noise. Everything is in the nuances of installation and the condition of the landing:

while sealing the technological gap between the frame and the wall with polyurethane foam ( cement mortar) sound bridges were left: the wedges (linings) were not removed or the sealing seam was allowed to rupture in the area of the mounting fittings;
during installation door block iron rods were used as linings for the box, subsequently simply cut with a grinder;
when sealing the slopes, they did not place mineral wool between the wall and the extension - they left an air space;
mistakes were made during installation of the seal: different tension of the elastic around the perimeter of the door leads to different pressing forces of the door leaf to the frame in different places;
remained hidden cracks walls near the doorway;
the eccentric responsible for the clamping force is not adjusted - the seal practically does not compress;
the seal is damaged;
the entrance is echoey, there are no materials that absorb sounds - leather or leatherette door trim or wood lining.

For economy class doors, the quality of sound insulation is additionally affected by:

thickness of the metal sheet on the door leaf;
thickness of the door block in general and the leaf in particular;
type and thickness of the filler between the sheets of door leaf;
presence of thermal break ( in simple words: whether or not the insulation was installed inside the door frame - not to be confused with the canvas).

Attention: experience shows that doors of expensive segments (Premium, Elite, VIP class, such as Torex) have a problem with good sound conductivity, usually in the sealing rubber.

Therefore, before starting large-scale work on soundproofing the door, you should check the operation of this element of the door structure. You can use two methods:

apply chalk to the seal and open and close the door several times - uneven chalk residues on the surface indicate poor sound insulation in the area where the door panel adheres to the frame;
insert a sheet of paper alternately into the door slot on each side of the leaf and move it in different sides. If different forces are required to manipulate the paper, the problem is in the compactor.

Ways to improve the sound insulation of your front door

Treatment of the disease is impossible without a diagnosis. So in our case - to improve sound insulation front door, without knowing the reasons, is expensive and labor-intensive. Therefore, we will indicate ways to improve the level of noise insulation by block:

1. Door frame. Here are several places where you can improve protection against various noises and, therefore, several ways to do this:

replace the seal;
install rubber seals along two contours - metal doors allow this;
install threshold slats with nylon brushes;
insulate the slope, which allows you to dampen sound waves penetrating into the apartment through wedges, microcracks in the wall or breaks in the seam made of polyurethane foam when sealing the technological gap;
insulate the frame from the inside of the door: stick it decorative overlays from MDF, wood, plastic, etc.

2. Door leaf. It is not advisable to carry out any work to improve the sound insulation of the door leaf at the doors of the expensive segment. With significant financial costs, this indicator can be improved by only 5-10%. Another thing is inexpensive doors, where the level of sound wave attenuation can be increased to 70%. Here you can do the soundproofing of a metal entrance door with your own hands by:

laying noise-insulating filler inside the door leaf - if the inner sheet of the leaf is removable;
replacing the metal sheet of the door leaf on the apartment side with a sheet of MDF, PVC, wood, etc. — the resonance effect disappears;
upholstery outside doors made of leatherette, leatherette or natural leather, under which a soundproofing substrate made of one type of material or a combination of several is placed;
performing similar work inside the apartment;
installation of second doors;
vestibule extensions.

Types of soundproofing materials for entrance doors

Knowing the reasons why noise enters an apartment, as well as methods to combat it, there is little left to do: find out how to soundproof the front door in an apartment with your own hands. First you need to purchase materials.

When replacing the seal or pasting it on the second contour of the door frame, it is necessary to purchase a sealing rubber band with a length exceeding the perimeter to be pasted by at least 20 cm. In one piece. The material may be different:

rubber;
plastopolymers (TPE);
artificial rubber;
silicone;
foam rubber

Each material has its own strengths and weak sides. You can learn more about them in the work: “”, subsection 4.2.

For doors, experts recommend using rubber or artificial rubber seals. Silicone is much more expensive, but consumer properties and service life is almost the same as the materials noted above. Foam rubber quite quickly loses its shape (deforms) in places of increased compression.

Can be used as a filler various materials. When making a choice, you need to consider the following points:

the material must be environmentally friendly;
have high levels of heat and sound protection;
do not absorb moisture;
have a service life commensurate with the service life of the doors;
to be in the middle price sector - to be affordable to the mass consumer.

Mineral wool made from rocks(basalt wool), polystyrene foam, penoplex, foamed polyurethane, foam propylene and corrugated cardboard for budget option doors.

Mineral wool from rocks. This is one of the rare building materials, which has practically no drawbacks, except for one thing - when wet by 2%, thermal conductivity increases by 10%, which is not a problem for metal entrance doors in apartments and houses. Among the advantages it should be noted:

affordable price;
environmental friendliness;
high levels of noise and heat protection;
resistance to high temperatures and open fire;
resistance to aggressive chemicals;
long service life.

Attention: other types of mineral wool: it is advisable not to use slag wool and glass wool due to large quantity disadvantages: they absorb water, have low sound absorption and high thermal conductivity, and settle over time, forming voids. In addition, slag wool, when in contact with water, releases acids that corrode the metal.

Styrofoam. The filler has:

low thermal conductivity with high absorption of sound waves;
long service life without loss of consumer properties;
affordable price.

In addition, it is frost-resistant and non-hygroscopic. Safe for people - does not emit harmful substances.

Among the disadvantages:

instant flammability upon contact with fire;
release of toxic substances into space during combustion.

Foamed polyurethane. The industry produces two types of insulation from this material: elastic and rigid. To fill the doors you need to purchase hard option. He:

lightweight and durable;
not afraid of water;
durable;
good insulation;
effectively absorbs noise;
environmentally friendly

Among the disadvantages, it is necessary to note the higher price compared to basalt wool and polystyrene foam and good flammability with the release of toxic combustion products.

Penoplex. The material has:

low thermal conductivity - about 0.030 W/m;
high level of noise absorption - 45%;
resistance to moisture - in 28 days it gets wet by only 0.5%;
long service life - 50 years.

It can be used in a wide temperature range from –50 o C to +75 o C.

The negative aspects of the material include:

quite high price;
ability to quickly ignite;
susceptible to attacks by mice and rats - they eat with pleasure.

Foampropylene. One of the best synthetic fillers, which has:

light weight;
high technology;
resistance to chemical reagents;
excellent hydro, heat and sound insulation properties;
service life is about 70 years;
no shrinkage.

The disadvantages include the same flammability, but it ignites only at +120 o C.

Corrugated cardboard. The cheapest filler with average sound insulation and low weight. Another advantage is the low price. Among the disadvantages is destruction under the influence of moisture.

Now let's look at how to improve the sound insulation of the front door when upholstering it. In this case, you can use mineral wool, isolon, synthetic winterizer, vibroplast, Splen, Bimast.

Izolon. Modern material, obtained by foaming polyethylene with propane. Possesses:

excellent heat and sound protection characteristics;
low water absorption - less than 1%;
high manufacturability - easy to cut and simple to install;
increased elasticity and flexibility;
environmentally friendly - does not emit toxic substances and does not cause allergic reactions;
light weight;
long service life - about 100 years.

Among the disadvantages, we note only the high cost.

Sintepon. In terms of price/quality ratio, this is the best acoustic material of all those offered on the building materials market. In addition, it does not support open combustion.

Vibroplast. The material came to the construction industry from the automotive industry, where it has been used for a long time. It is a self-adhesive composite made of aluminum foil and polymers. Easily laid on complex terrain without heating.

The advantages include moisture resistance, flexibility, elasticity and the ability to dampen vibration noise. The only disadvantage is the high price.

Splen. Another material that came into construction from the world of motors. It has excellent sound-absorbing characteristics with average thermal conductivity. Due to the small thickness (4 mm), when upholstering doors, you can create a sandwich of several materials.

This approach increases heat and noise protection (in Lately The combination of splen+sintepon is very popular, in which sound absorption reaches 50-60 dB).

Bimast. Modern vibration-absorbing material based on bitumen. It is used only in the form of a sandwich, where it acts as a spacer between metal sheet door leaf and soundproofing material. Like Spleen, it is increasingly used for soundproofing metal doors.

The material has several serious disadvantages:

begins to melt and flow down at temperatures above 30 o C;
Applicable only to metal surfaces;
complex application technology;
the metal surface must be perfectly cleaned of grease;
attached while hot - you need a hair dryer.

Instructions for soundproofing a door yourself

Everyone has it technological process Construction has its own order of work. And it always starts with materials and tools.

Materials and tools

Before soundproofing the front door, you need to buy materials and assemble necessary tools. Materials you will need:

filler;
soundproofing substrate;
upholstery;
decorative nails;
seal;
self-tapping screws;
glue;
polyurethane foam.

The toolkit should include:

hammer;
electric drill with a set of drills;
stapler;
a screwdriver or several Phillips and slotted screwdrivers;
scissors;
hair dryer for construction work;
knife with removable blades.

The given list of tools and materials is always detailed for a specific method of sound insulation.

Seal installation

In most cases, replacing the seal solves the problem of a noisy apartment. The step-by-step work algorithm is as follows:

a sealant is purchased. It should be slightly longer than the perimeter of the doors, the width should not extend beyond the rebate of the door frame, and the thickness should be 2-3 mm greater than the gap between the door leaf and the frame.

This indicator is the most important - it determines the protection of the apartment from the penetration of noise and cold, as well as the easy closing of doors. The material will be thinner - the room will be noisy, thicker - the door will be difficult to close. In order not to guess, but to immediately buy the necessary sealant, you need to do a little trick: wrapped plastic film Press the plasticine into the fold of the door. Add 3 mm to the resulting thickness of compressed plasticine - dimensions sealing gum received.

the entire perimeter is degreased with alcohol, white spirit, acetone or special solutions;
the corner from which work will begin is coated with universal glue;
the tip of the seal is cut at an angle of 45 o, the protective film is removed from it by about 40-50 cm, after which the elastic is glued to the corner;
gradually removing protective film, the elastic band is glued around the perimeter of the box, laying it quietly, without pulling;
the end of the seal is also cut at an angle of 45 o and glued to the beginning of the elastic band;
Using your hands or a special roller, the seal is rolled along the entire length to the box material.

Replacing the filler

You can increase the sound insulation of your front door by replacing the filler with more efficient material(this method is only possible with collapsible doors). For this:

the door leaf is removed from the hinges and laid inside up;
the handle and lock linings are removed;
the inner sheet of the canvas is dismantled;
the existing filler is removed;
new filler is installed. If it is self-adhesive (isolon, polyethylene foam), there is no need to carry out additional operations. If there is no glue on the material, then the outer sheet is degreased and then lubricated special glue(“Moment”, “Superglue”, etc.);

Attention: the glue is applied in small strips. For mineral wool such an operation is not provided.

filler joints are foamed with mounting foam or clogged with mineral wool;
the edges of the removed panel along the entire contour are lubricated with any type of sealant;
the door leaf is returned to its place;
the removed fittings are installed;
the door is hung on hinges.

Door trim

Most effective option soundproofing of doors - their upholstery, regardless of whether it is made inside or outside the apartment. Several problems are solved here:

the apartment is protected from noise on the landing;
the doorway is insulated;
is improving appearance door leaf.

Many owners call specialists to carry out upholstery work. But even beginners can do such work on their own. Enough desire and patience. Here are instructions for door trim.

Remove decorative nails that secured old upholstery to the door leaf. Remove the fittings.
Remove the upholstery.
Remove old insulation, as well as hardboard or fiberboard if they are under the upholstery.
Wipe the surface of the door leaf with acetone or alcohol - degrease.
Glue vibration-proof material (which material to choose, see above).
Using adhesive sealant, stick on bitumen material foam rubber, padding polyester or other lightweight sound insulator.
Trim off excess material.

Attention: mineral wool is attached with a fishing net to a door laid horizontally.

Upholstery is being carried out.

In the minds of the average person, upholstery is associated with leatherette, artificial or natural leather. In fact, upholstery can also be done with various panels.

To install the panels you need:

install the sheathing along the edge of the door leaf using self-tapping screws (you must drill a hole in the slats for them in advance);
cut holes in the panel for peepholes, locks and handles;
attach the panel to the sheathing with liquid nails;
treat the joints of the plank and panel with silicone sealant;
decorate the sheathing at the end of the doors with special strips;
install fittings.

Soundproofing a wooden entrance door

There are two ways to protect yourself from various types of noise when using wooden entrance doors:

stick the seal on the door frame;
upholster the door with leatherette (genuine leather) or leatherette.

The technology for gluing the sealing gum is discussed above. We will consider leatherette (leather) upholstery below.

The door is removed from its hinges and placed on the floor or table.
The handles, peephole and lock linings are removed.
Along the entire perimeter of the door, strips of leatherette (leather) 15 cm wide, wrong side up, are nailed in 10 cm increments.
Leatherette is cut with an overlap of 5 cm around the entire perimeter.
Foam rubber or padding polyester is attached to the door with a stapler. Holes are cut in the material at the locations of the eye, handles and lock.
Batting is attached on top of the foam rubber - it extends the service life of the insulator.
At the top of the door, in the middle, leatherette (leatherette) is attached with a nail. The same operation is performed from below.
In increments of 10 cm, the decorative canvas is nailed to the door along the entire perimeter.
The batting is cut into strips, rolled into rolls, after which the previously nailed strips are attached to the door with decorative nails.
The peephole, lock linings and handle are returned to their place.
If desired, you can nail a decorative cord in the form of a beautiful pattern.

Conclusion

Having considered how to improve the sound insulation of the front door, we can draw brief conclusions:

Improved sound insulation requires doors not only in new buildings, but also in residential premises;
You can increase the level of noise protection in several ways: seal the vestibule with a sealant; replace the filler inside the door leaf; upholster the door with soundproofing material;
the work does not require special training;
simultaneously with increased sound insulation, the functions of the doors to protect the room from the cold are improved.

Video on the topic

1. Increase the weight of the door

The door must be massive. Massive is 30–40 kg/m2. Suitable either steel doors, or wooden, made of solid wood, you can use chipboard, OSB or MDF.

2. Eliminate cracks

The door frame must be sealed along the contour of the rebate. A threshold is required: stationary or (drops down when the door is closed):

It is best to use a D-shaped rubber gasket for sealing. Remember, the greater the tightness, the higher the sound insulation of the door.

3. We arrange the vestibule

If you need to achieve high sound insulation, you can use two doors, i.e. arrange entrance group in the form of a vestibule. The greater the distance between the doors, the higher the sound insulation. Sound-absorbing materials must be placed on internal surfaces.

4. Remove keyholes

They transmit sound well and should be avoided if possible.

5. Reducing the gaps

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

Example of an interior door with sound insulation:

A speaker is installed in the room and a noise signal is turned on with a volume of 90 dB at a distance of a meter from the source. The soundproofing of the door was achieved by the difference in the noise level inside the room and outside when the door is closed.

According to the test results, we received sound insulation R w ≈38 dB (with additional panels and platbands it will be even quieter)!

Given the demand for doors with high-quality sound insulation, today domestic producers offer a whole range of solutions - these are paneled doors made of solid natural wood.

Doors with a polymer seal or special folds, the use of cellular cardboard as a filler for the voids of the door leaf, and for doors with a PVC frame - the use of two- or three-chamber double-glazed windows, 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 a lot of grandchildren. Children often make noise. But my wife and I want peace and quiet. We ordered soundproof interior doors from you. We didn’t even expect that our room would really become 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, it will only be from you.

Kletchenko Inna:
I have been looking for soundproof interior doors for my parents for almost a month. Dad rejected several options. And he only liked yours. He said that he couldn’t have done it better himself. I was even surprised when I heard such praise from his lips. Covering, locks, handles - we all liked everything. With delivery and installation, everything also happened very quickly. I will soon be doing my own repairs, I won’t even bother looking anywhere else. I will definitely order from you again.
