Coziness and comfort in the house can be ensured only with good sound insulation. Today there is a huge selection of materials, thanks to which you can get the necessary silence. It is worth noting that if soundproofing is done in an apartment, then it is necessary to use only an integrated approach.

@ Dver'_s_shumkoi

Soundproofing problems are especially familiar to apartment owners. Due to the thin walls and the lack of insulating layers, you can sit on the couch at home and listen to what is shown on the TV from your neighbors. Such comfortable conditions few people may like it, and the only correct solution would be sound insulation. As you know, any sound passes well through the air, and if there is, at least small space it will be impossible to achieve the result of sound insulation.

If everything is more or less clear with the decoration of walls, ceilings and floors, then few people thought about the interior door and its level of sound insulation. The thing is that in modern apartments, the construction does not provide for sills that create a soundproof barrier. It is under the interior door that any noise and sound can pass. Today this problem can be solved using a special retractable sill. Some manufacturers install these mechanisms to obtain maximum effect... If there is no addition on the canvas, then it is better to take care of this in advance and install or purchase another design.

The walls, ceiling and floor are insulated, but the sound from the next room enters the room. It would seem where to come from, but as it turns out, no less noise comes through the windows and doors into the house than from the neighbors. With installation metal-plastic window you can solve one problem and reduce the noise level. The remaining interior door also affects the level of sound absorption. The proposed material will tell you how to perform high-quality and effective noise protection of an interior door.

@ Dver'_s_shumkoi

It should be understood that the design door leaf one of the most important components of insulation. Common door options include plastic, wood or chipboard and MDF panels. There are hollow and honeycomb products, depending on the design of the canvas, it is selected and the best option noise insulation. An important point, it is impossible to make soundproofing of the door with glass elements. As you know, glass transmits sounds well, so it is better to replace the door leaf with another one with better insulation performance. By filling the door structure with noise-insulating material, you can most effectively protect the room from noise.

Choice of materials

When soundproofing an interior door structure is planned, the choice of insulating material is quite difficult. The thing is that today there is a huge selection of materials that meet the requirements and parameters. First of all, when selecting insulating materials, you need to pay attention to products that are applicable for interior designs... The most commonly used insulators for doors are slabs:

• foam rubber;
• padding polyester;
• mineral wool;
• isolona;
• polystole;
• foam.

The choice of sound insulation material is also influenced by the characteristics of the insulation. There are products that, with prolonged use, shrink, which means that in a few years the door leaf will have to be changed. If you use more expensive materials, then despite the high cost, their service life will be an order of magnitude higher. All types of noise insulation are applicable for internal use in the door structure.

@ Dver'_s_shumkoi

With a solid door leaf, an automotive vibration filter and splenie should be used as an insulating material. The foil material will provide the required level of sound protection. As for Splena, it is used in the form of a sound-absorbing layer, as well as thermal insulation.

Despite the small thickness of the product, the rubberized base can contain vibrations and absorb sounds. The adhesive base will help to fix well insulation material without letting it peel off. Due to its characteristics, it is this insulating filler that is used to de-noise a car.

Advice! Do not use for soundproofing interroom door products insulation materials such as polyurethane and corrugated board. As for polyurethane, it is quite difficult to apply it and the structure becomes unrepairable. If you use corrugated cardboard, then after a short period of time it will have to be changed.

Preparatory work

Before proceeding with the noise insulation of interior structures, it is initially worth preparing everything. It should be understood that adding soundproofing material to the door leaf structure will increase the total weight. The hinges must be reinforced to support the weight. The optimal solution gain will additional installation pairs of curtains. Thanks to this reinforcement option, the door leaf will not sag or warp the entire structure.

@ Dver'_s_shumkoi

When soundproofing an interior door, the opening itself is also important. If the wall and frame are not insulated, then the result of sound insulation should not be expected. As a rule, the doorway is foamed, thereby providing an optimal sound-absorbing effect.

It is important to understand that if you install a soundproof door, then its characteristics will not be enough to protect the entire home. Only comprehensive sound insulation will help protect the room from sounds coming from other rooms.

To work on soundproofing the door leaf, you will definitely need various tools and it is necessary that they always remain at hand. It should be understood that it is much easier to deal with doors when they are removed from their hinges.

Dismantling the casing

Mostly people trim the front door various materials, due to which the indicator of heat and sound insulation increases. Sometimes cladding is needed to hide old door, giving it an attractive look. As a rule, the sheathing is attached to wood surfaces with small decorative nails. With metal structures, everything is a little more complicated, plywood is glued to the panel, and after that the finish is applied.

@ Dver'_s_shumkoi

Depending on the cladding material, the level of dismantling complexity is also determined. A simple vinyl-clad wooden door can be easily disassembled without any special equipment. When it is necessary to change the trim on metal products, the procedure can be delayed. It is easier to disassemble the panel if it lies horizontally.

First, the doors are removed from the hinges and placed on a flat surface. Accessories, locks and other structural elements are also removed. After carrying out work with sound insulation, they are installed in their original place, while appearance and the characteristics of the material are completely different.

Self-insulation of interior doors

Despite the fact that soundproofing is a rather complicated process, all types of work can be carried out independently with everything you need at hand. Modern soundproofing materials allow you to choose exactly what is needed in accordance with the technical parameters and cost of the material. For doors, you can use slabs, mats, vibration-absorbing pads, etc.

@ Dver'_s_shumkoi

To carry out sound insulation, a number of works must be carried out:

1. Remove the door leaf, and glue the seal around the entire perimeter of the frame.
2. If on front side there are mechanical cracks, they must be sealed with a sealant.
3. If the design of the canvas is collapsible, then in the middle you need to fill a soundproof filler.
4. The outer part of the structure can be additionally pasted over with plastic panels.
5. Install an automatic nut in the lower part, which will keep sounds passing from below.

With an integrated approach, it is possible to effectively protect the structure from the passage of noise and sounds. If the surfaces of the walls, ceiling and floor are not insulated, then no matter how high-quality the doors are, such sound insulation will not give a result.

Stages of soundproofing interior doors

If the door in the apartment is installed according to all parameters and the manufacturer's recommendations, the structure is capable of absorbing up to twelve dB of sound. In the case when an additional level of noise isolation is used, the sound waves are absorbed more efficiently. There is a certain order of actions:

• Seams and cracks should be completely sealed using a sealant.
• The door is processed from the side of the penetration of sounds.
• Modern soundproofing boards allow easy installation. The plate is glued with mastic directly to the canvas, and a decorative material is installed on top of it.
• A seal is glued around the perimeter of the door frame. The thickness of the gap along the entire perimeter should not be more than 0.5 centimeters.
• Installation of a nut to minimize the passage of sound waves at the bottom of the structure.

Today there are many product options that guarantee effective protection from various noises, while the main thing is to choose the right material.

Sound insulation of a door with disassembly of the leaf

Some doors can be disassembled, which greatly simplifies the noise reduction procedure. For such structures, it is important that the material inserted in the middle is not only fixed, but also provides the required level of insulation. A good option insulation mats can serve. Due to the relatively small thickness of the product, it provides a sufficient level of protection against airborne sound. It is also worth noting that this insulator contributes to the heat saving of the door leaf.

@ Dver'_s_shumkoi

Dismantling the door begins with the dismantling of the hardware. It should be noted that this procedure much easier to do if the canvas is removed. You need to remove not only handles and locks, you also have to dismantle cladding panel... The ease of the procedure depends on the material used. If the canvas is sewn up with fiberboard, then it is necessary to dismantle it from the end part. Using a flat screwdriver or knife, the sheathing layer is lifted. Since carnations are mainly used in such structures, they all need to be pulled out and the canvas will peel off from the frame.

Recently, they often use interior products made by veneering. A veneer under a tree or other texture is glued to the frame. In order to disassemble the product and not prematurely destroy the lining, you can try to warm up the edges with an iron and a cloth. The veneer will begin to flake off, and gradually warming up the canvas, there is a possibility of complete removal without damage.

If the door is hollow, then it is difficult to install a suitable noise isolator along the entire interior. As material will fit fiber backing board or soundproofing mat. When laying the material, it is necessary that it does not protrude beyond the edges of the housing. It is also important that the insulation is of sufficient length and width so that it can be distributed throughout the entire space of the box. When the insulation is completely laid, you can sew up the structure with a facing sheet.

Of course, it is not always possible to neatly dismantle the panel or install it back. In case of damage to the face, you must try to correct the defect. A small crack should be covered with quick-drying glue, and after drying, polished to a perfectly smooth surface. If the problem cannot be solved in a simple way, then as an option, you can try to buy a special adhesive film that is glued to the surface, creating an absolute smoothness.

Soundproofing around the outer perimeter

The outer part of the door can be upholstered with dermontin, leather or vinyl. Of course, the upholstery material itself has a certain soundproofing effect, but it is insignificant. It is better to use a lining made of noise-insulating material, in which case it will be possible to achieve the expected result. The thickness of the insulation is not needed too thick, 3-5 millimeters are enough.

@ Dver'_s_shumkoi

Insulation is applied to the canvas over the entire plane. It is necessary that the material does not protrude beyond the edges, but at the same time is level with the frame. The insulation can be fixed with glue or construction stapler... It is better to start nailing the material from the top of the door. Thus, the formation of irregularities and mesentery can be minimized. When the canvas is completely sewn up, the next step will be the installation of the decorative part. The upholstery can be done with decorative nails with wide heads so that the dermontin does not tear. You can pull a thin cable or a thick nylon thread to improve fixation between the nails being driven in. You can make the door trim yourself, but it is better to resort to help. To enhance the soundproofing effect, doors can be sewn on both sides.

Soundproof door fittings

For maximum soundproofing of the door leaf, it is necessary that not only the door leaf is sewn up with insulation, but also the appropriate fittings must be used. The lock mechanism, handles and hinges must be securely fixed in the door leaf. If necessary, you can additionally treat the fittings with a sealant. Speaking of insulation, it is also important to cover the door frame with insulation. Worth knowing! Insulation can be tubular or embossed, and it must completely cover possible cracks and seams.

@ Dver'_s_shumkoi

If you want the structure to last as long as possible and at the same time be effective for sound insulation, it is recommended to use high quality building materials. With a well-done work, the service life of the door leaf can reach 50 years. Depending on the level of noise protection, the appropriate material is also selected. You should not take sound insulation, which is many times higher than the level of need, since such materials will be an order of magnitude higher, and the result will remain the same as the cheaper options.

Classification of soundproof doors

At the moment, there is a lot of soundproof doors on the market, and in order to understand everything, it is necessary to consider each class separately:

1. Swing. Such designs provide for the opening and closing of the opening from one side or the other, it all depends on the design features of the apartment and personal preferences. Swing structures- these are ordinary ones, which consist of one canvas. The main feature of such structures is that they have decorative cladding on both sides, which can complement the interior design and become its complement.
2. Sliding products are quite difficult to install and their soundproofing qualities are insignificant. Due to the fact that the canvas consists of two parts, it is quite difficult to make effective sound protection. In most cases sliding mechanism needed as a decorative element.
3. Folding interior doors... As for such structures, for effective noise protection, it is necessary that each sash has additional insulation at the joints. Considering the fact that the products of this type often has glass in the design, then there is no need to talk about its effectiveness.

Each class of products is unique and individual in its own way. Depending on your needs, you can choose one or another version of the product. To ensure maximum sound insulation, it is better to use a model with a swing mechanism. Despite their simplicity of design, they are considered the best as soundproof models.

@ Dver'_s_shumkoi

Additional methods of soundproofing

Some interior doors have standard sound insulation, which was installed at the manufacturing stage. Sometimes standard isolation is not enough and you have to make your own adjustments. To ensure the optimal level of sound insulation of the interior door, you need to glue the door frame with a sealant. The width of the seam between the canvas and the box should not exceed two millimeters. Also, pads made of thick paper or plastic can be used as an insulating layer. Naturally, one should not expect too much efficiency, however, in conjunction with the sound insulation of the door leaf itself, you can get a good result.

@ Dver'_s_shumkoi

As additional sound insulation, you can use blackout curtains located directly above the opening. This option was used by our grandmothers, but it is actually effective. If, after trying a lot of options, you did not manage to achieve the expected effect, you should completely change the door model to a new one with good sound insulation.

Soundproofed interior doors

When there is a need for maximum protection of the interior door leaf from extraneous noise, only effective sound insulation will resolve the issue. Currently, there are many options for insulation from various sounds that can be used when modernizing a door leaf. Thanks to modern production technologies, doors can be made with maximum sound insulation, but without compromising the strength of the structure.

In the production of soundproofing, doors are used multilayer technology, due to which is achieved maximum efficiency without loss of strength. Each individual layer is made of sound-insulating and sound-absorbing material, so that the finished canvas is protected.

The main types of materials for sound insulation are: chipboard, MDF and fiberboard. Thanks to the fibrous structure, the expected result is achieved. For additional effect it is covered with veneer foil and plastic. To be sure of the quality of sound insulation of interior doors, you should order the product from the manufacturer or from a trusted supplier.

How do soundproof doors differ from conventional models?

Along with what the market offers big choice conventional interior structures, it is quite difficult to determine which of them have sound insulation. If the purchase of a canvas is envisaged in the market, then the seller, for his own benefit, may sell you a completely wrong product that you need. In order not to get into an unpleasant situation, it is important to look at such nuances:

• When buying a structure, you need to check the quality certificate and other documents;
• If the canvas is from the manufacturer, then it has a protective film with the company logo and characteristics;
• Do not buy doors without first checking;
• Availability of high-quality fittings;
• One of the indicators of quality is the cost and the embossed logo of the manufacturer.

Having dealt with all the subtleties, you can choose the perfect canvas for an apartment, which will have a sufficient level of sound protection.

How to choose a door with good sound insulation?

Today, the variety of interior door designs is so great that it is quite difficult to choose one thing. It is especially difficult if you come to a building materials store, then without knowing some points it will be problematic to choose the required canvas.

When choosing interior door products, first of all, you need to look at models with good sound insulation. As a rule, such products have in their construction a fibrous material that provides required degree protection. It should be understood that canvases with glass inserts they poorly isolate sounds, so it is better to give preference to solid structures.

When you choose interior designs, you need to look not only at the canvas, but also the door frame. It is important that the width of the seams between two products does not exceed two millimeters, in otherwise the soundproofing will be very poor.

To purchase a high-quality product, you should contact special centers where original products are presented; in this case, you can exclude the purchase of low-quality goods. If the decision to purchase is made, then you should definitely inquire about the composition of the canvas and accessories. If there is documentation, then it is worth comparing the data in the documents and designs.

Today, products are often sold via the Internet. You can buy a high-quality door for a room if you cooperate with a trusted supplier or if the online store works directly from the manufacturer. When choosing a product on the Internet, it is important to initially require documentation, if everything is in order, you can make a payment.

A visual assessment of the door leaf is also important, since a quality item is immediately visible or not. The front part of the canvas should not contain defects, the corners should not be knocked down and all the accessories in their place. High-quality fittings can be noticed not only visually, but also by touch. On such grounds, you can determine the quality of the proposed product.

What are the fillers to provide sound insulation?

Today, doors can protect not only from penetration into the middle of intruders, but also cold air and different types noise. If for the reliability of the structure you need to look at the specifics of the product, then for sound insulation, special attention should be paid to soundproofing materials.

If the doors have a hollow structure, then mineral wool or basalt wool, mats and self-adhesive materials can be used as insulating material. Also, the level of permeability of noise can be reduced by the upholstery of the door leaf. The combination of several types of filler will help insulate the canvas as much as possible, so that with such doors it is not only comfortable, but also quiet.

Coming home after working day, we want to relax and enjoy the silence. But this is not always possible: sometimes the noise from the street or from neighboring apartments is very intrusive. To protect yourself from intrusive sounds and ensure a comfortable stay at home, you need to soundproof your home. Soundproof doors will help with this.

Why do you need sound insulation in an apartment?

Sound insulation is the reduction of the amount of noise that enters the home. It is achieved by sealing walls, windows, ceilings and doors. The noise level is specified in decibels. This characteristic established by state standards and measured with a special device.

It is impractical to install in an apartment soundproof doors if windows and walls do not have these properties. If you still decide to protect yourself from noise, then you need to do this from all sides.

Soundproofing your home can help you relax, relieve stress, and protect your nervous system from negative influences... Such doors are especially relevant for children's rooms. They will provide your little ones with a calm and comfortable rest.

In addition to smoothing out noise, soundproof doors perform a number of related functions:

• Anti-corrosion. The insulating filler prevents the development of mold in the sashes of interior doors.
• Durability. Since "quiet" doors require additional reinforcement, this strengthens their structure. Makes it heavier and more resilient.
• Keeping warm. Most noise-suppressing materials have thermal insulation properties... They eliminate drafts, restrain the penetration of cold into the apartment.

Thus, by purchasing soundproof doors, you get a few more pleasant bonuses.

Types and materials

Conventional doors are capable of withstanding noise levels up to 30 dB. But if there is a need to improve the soundproofing properties of a door block, soundproofed doors come to the rescue.

Externally, soundproofed models are similar to standard ones, but inside them there are layers of soundproofing material. This could be:

• Sintepon- rather soft fiber, characterized by high durability. For good sound insulation, it is arranged in several layers;
• Polystyrene has good soundproofing properties. Release form: granules, sheets or liquid;
• Mineral wool- fire-resistant material, but capable of absorbing moisture and shrinking over time;

• Foam rubber- the cheapest raw material, most often used for the door leaf;
• Splen or acoustic foam. The sound wave, penetrating into it, is lost and does not find a way out. It is glued to the surface with a sticky layer, which ensures a tight fit;
• Izolon it is also a derivative of foam rubber, but significantly benefits against its background;

• Styrofoam protects well against noise, but has low fire-resistant qualities. Not the most suitable option;
• Foamed polyurethane- good soundproofing sheet. Has a high resistance to fire;
• Vibration filter- multilayer material, which includes bitumen and aluminum foil. Provides tightness, as due to its elasticity it adheres tightly to the surface. This increases its soundproofing ability.

In addition to ready-made soundproofed doors, there are types of soundproofing with which you can independently complement your usual entrance accessories:

• Lay the above-mentioned insulating fillers inside the canvas;
• Install additional panels that are attached to the main canvas. It can be fiberboard, MDF, laminate, lining, leatherette;
• Installation of the second door. At the same time, not only the additional canvas, but also the air space between the doors will help to reduce the level of noise entering the apartment.

Additional soundproofing methods

Such simple devices will also help to increase the effect of sound insulation:

• Automatic threshold: A magnetic strip is installed in the floor. When the door is closed, it connects to the metal strip in the door itself, which ensures an airtight closure.
• Door frame. If it is made of metal, then the box is filled with concrete from the inside. If made of chipboard, it is used polyurethane foam... The goal is to reduce the gaps between the opening and the frame. According to the standards, their size is allowed up to 1 cm.
• Sealant located around the perimeter of the doorway. It also achieves hermetic closing of doors. Of the most used are:

• rubber bands or pipes;
• foam rubber (soft yellow tape);
• isolone ( white, in terms of density higher than foam rubber);
• silicone contour;
• magnetic (provides the greatest tightness).

Almost all seals are equipped with an adhesive base, thanks to which they are fixed to the door. The exception is silicone, which is attached with a plastic rib. The seal is the lightest and most effective option to enhance the soundproofing of doors.

Standards

First of all, soundproof apartment doors are designed to inhibit the passage of sound from the street to the apartment.

There are the following types of noise:

• Airy: is born in the atmosphere and through sound waves passes through an obstacle;
• Impact: formed as a result of any manipulation (rearrangement of furniture, jumping). It is measured with a "top" machine.

State standards insulation standards have been established for both noise categories.

It is worth mentioning the classes of houses, since each category has its own norms:

• Class A: superior comfort;
• Class B: comfort of existence;
• Class B: Acceptable Conditions.

The suppression of airborne noise is carried out not only by doors, entrance and interior, but also by surfaces of other structures. A special term for sound insulation has been introduced. It characterizes only one design.

Measured in decibels and determined by the insulation index:

• class A room - 54 dB;
• class B room - 52 dB;
• class B room - 50 dB.

The impact noise index of an apartment and interior door is equal to:

• class A room - 55 dB;
• class B room - 58 dB;
• class B room - 60 dB.

Noise isolation levels

Noise is a rather unpleasant sound. It irritates the nervous system, is able to unbalance. A person reacts calmly to sounds in the range of 25-60 dB. When exposed to high sound waves of 90 dB for a sufficiently long time, nervous disorders in the form of insomnia and neuroses can develop. At a sound of 100 dB, a person can become deaf.

To protect yourself from strangers negative impacts, choose doors with good sound insulation for your home. They are of the first level and advanced.

The first class includes doors that are able to protect against a noise flow of 32 dB. In comparison, the sound wave of a conversation is 45 dB. Reinforced structures withstand noise levels of 40 dB or more. It all depends on the material of construction.

Doors made using sandwich technology have good soundproofing properties, that is, they have several layers of sound-absorbing material. Plus, on the outside, such products are lined in the form of MDF or leatherette panels.

How to choose the right one?

First, decide what you need to isolate. If we are talking about a door for a house, then here, perhaps, option will do its independent soundproofing. The thing is that, according to the standards, the door structure must withstand 26 dB. Thus, if outside the noise level is 60 dB, then 34 dB penetrates into the room. And a sound wave from 25 to 50 dB is considered comfortable for a person. Therefore, for such sound insulation, it will be enough to independently lay insulating material or reinforce the door trim, install a seal or a sealed threshold.

If we are talking about a specialized room (recording studio), then it is better to purchase a ready-made model. To date, manufacturers offer enough wide choose inter-apartment doors to resist noise. Outside, they are like ordinary door constructions, can be finished with chipboard, MDF or laminate. But the inside must necessarily contain several layers of insulating filler.

Good reviews about sound insulation properties are received wooden doors from oak or pine. Fire protection models also help to reduce the penetration of sound. Their heat insulator is able to suppress sound up to 45 dB.

Separately, it is worth talking about room doors... It is not necessary to install all soundproofing interior doors in the apartment. It is enough to choose several rooms where it is really necessary. This could be a bedroom or a children's room.

Interior doors, as the name suggests, are designed to separate rooms from each other, to delimit space. However, in addition to aesthetics, they must provide sufficient soundproofing.

If ambient noise from the street interferes with your concentration, you may need to replace balcony door for a model with increased sound insulation.

Comfortable for humans the volume is considered to be 30-50 dB, large indicators are annoying. The task of windows and doors is to maintain a comfortable noise level in the room, not to let loud sounds enter the room.

Soundproofing of doors is regulated by several regulatory documents: GOST 26602.3-99 “Window and door blocks. Method for determining sound insulation "; SNiP II-12-77 "Protection against noise"; SNiP 2.08.01-89 "Residential buildings". So, in living rooms In apartments, the noise level should be no more than 30 decibels (dB), and, for example, in sales areas of shops and airport waiting rooms - no more than 60 dB.

Classification of doors

Different types of doors provide different sound insulation. Plastic ones are the worst at dampening external noise. Low and soundproofing properties of doors operating on the principle of roller shutters, which consist of a set of aluminum (less often wooden or plastic) slats.

Folding interior doors provide perhaps the least sound insulation possible.

The absorption of sound by panel doors largely depends on their design. Made according to old technologies (frame made of wooden slats sheathed sheet materials similar fiberboard or MDF) poorly absorb sounds, since they have many voids. In some cases, the noise is even amplified (resonator effect).

Total soundproofing. Not required to be installed in all rooms soundproof doors... Choose exactly those parts of the room where you really need to protect yourself from noise: a bedroom, a children's room, a study, a music studio ...

Modern technologies for the manufacture of panel doors involve filling the internal volume with cardboard, laid like a honeycomb - we get doors with better sound insulation... Compared to wood, cardboard itself is less resilient and less prone to sound transmission.

If you plan to use doors from an aluminum profile, then you should remember about its high sound conductivity. But it takes about 10-15% of the door area, so the contribution of the profile itself to the sound-insulating properties of the door is small. Filling is more important. If it is a single glass, the achieved sound insulation of the doors will be very low. Another thing is a double-glazed window (two, three or more glasses with air spaces between them located as a "sandwich") or a sandwich panel, which consists of a foam material (polystyrene, expanded polystyrene, etc.), lined with plastic. The indicators of a single-chamber double-glazed unit (of 2 glasses) and a sandwich panel are quite high, and of a two-chamber unit (of 3 glasses) are almost ideal for most rooms in the house.

Sound insulation of sliding doors is lower than swing doors, if only because of the gap that inevitably exists between the sliding doors.

Solid hardwoods have good performance. After all, other things being equal, the heavier the door, the better protection from the noise it provides. However, in any case, the sound insulation of interior doors is low: the existing noise level is reduced by 10-20 dB.

The use of double rebated doors is very effective. The canvas on the outside has protruding edges (folds, or "overlap"), which are additionally pressed against the plane of the box, most often in combination with a polymer seal.

Two doors. An interior door with improved soundproofing properties can be too expensive. Or, in its appearance, it can stand out from the general interior design. In this case, it is recommended to install two standard doors with a small air gap between them. Air also acts as a sound insulator.

Noise protection

If you need to equip a recording studio at home (which requires silence) or, conversely, you like to play on musical instruments and do not want to disturb the neighbors, you will have to pay attention to the special doors. Look for the marking according to SNiP II-12-77 "Protection against noise". He specifically stipulates that specialized soundproof doors must absorb at least 26 dB (for example, on the outside, the noise level is 50 dB, and inside the room - no more than 24 dB).
Such doors are no different from ordinary ones outwardly. The finishing of the canvas can be any. Special properties are achieved by internal device that resembles a layer cake. The canvas is glued from fiberboard, chipboard or MDF with layers of mineral wool and sound-absorbing plastic. Number of layers in doors different manufacturers may vary. This technology can reduce the noise level by 27-42 dB. In addition to the special design of the door leaf, such doors are equipped with special frames with thresholds.

On the picture:

Examples of interior doors on a metal frame.

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, they are filled with concrete (for metal box) or polyurethane foam.

The smaller the gap between the blade and door frame, all the better. According to the rules, its value should be no more than 1 cm. To prevent sounds from penetrating through the cracks along the perimeter of the canvas, use a seal - a rubber profile hollow cord, similar to that used for plastic windows... It also increases thermal insulation.

Make sure that the leaf fits snugly to the platbands: any gap is a loss in the sound-insulating properties of the door.

To reduce the noise level from under the door, a sill is installed. In addition to the usual wooden, plastic and metal, there are special heat and sound insulating thresholds made of combined materials, supplemented by a brush seal. The threshold must be at the doors of toilets, bathrooms (these are requirements not only for sound, but also for waterproofing the room). In all other cases, if you do not want to stumble over it, you can limit yourself to installing an inconspicuous brush seal in the bottom end of the door.

DIY soundproofing

You can also "modify" an ordinary door, sheathing it on one or two sides with appropriate acoustic materials: upholstery on a fabric basis, natural or artificial leather, dermantine, vinyl leather in combination with a soft filler (batting, synthetic winterizer, foam rubber). To increase the fire resistance of the door, it is recommended to use mineral wool as a filling. Simple paneling of the door with a wooden lath will help to improve sound absorption.

Do not forget about the possibility of installing two doors sequentially one after the other. The two most common models will give more effect than one special soundproof door.

Remember that installing the correct door and frame alone will not solve the soundproofing problem. A set of measures should be taken to isolate the entire room: ceiling, walls, floor, windows.
