Modern apartment is always full of sounds and noises, which can be caused by busy traffic, traffic outside the window or loud music, work household appliances... The use of soundproofing and noise-absorbing wall coverings alone is not enough; to reduce the level of discomfort, it will be necessary to install soundproof doors. Choosing the right model is not as easy as choosing armored or insulated options. It is more difficult to assess the sound insulation characteristics of doors than to measure the thickness of metal or insulation, so you have to rely only on common sense and the recommendations of specialists.

Requirements for the construction of a soundproof door

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

It is important that soundproof interior doors meet several additional criteria:

• The thickness of the sheet is not less than 48-50 mm, thinner sheets of pressed laminated cardboard, plastic or wood fibers do not have the necessary soundproofing qualities to reduce noise to a level of sound comfort of 20-22 dB;
• In the design of the door frame and the sound-proof door leaf, rebates or double bolsters with an additional sound seal must be provided to prevent the propagation of a sound wave through the cracks and joints in the door frame;
• The lower edge of the soundproof interior doors always equipped with either a guillotine or brush seal... The size of the gap between the floor and the lower edge of the door leaf can reach 10-15 mm, and without a seal it is quite difficult to achieve high sound insulation characteristics;
• Use of additional soundproofing strips for door awnings and hinges. Metal conducts sound very well, so all metal fittings must be shielded.

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

The more materials with high density and elasticity are used in the construction of soundproof doors, the worse things are with blocking noises and sounds. For example, the most massive entrance door made of metal with the thickest door leaf has not the best soundproof characteristics.

Even laying a layer of mineral wool inside the frame allows you to reduce the pressure of the sound wave by a maximum of 10-12 dB, that is, two times. The reason for the low sound insulation performance is that armored and steel doors have a large number of steel ribs and lintels, which, with any layer of mineral wool, will work as a kind of sound bridges, passing noise into the room.

Manufacturers are taking a more radical step - for the manufacture of soundproof entrance doors inner space the steel box was sheathed with a layer of foamed polyethylene. As a result, it is possible to improve the parameters of soundproofing protection by 12-15 dB, and when using a decorative cover made of MDF, it is possible to achieve 17-20 dB, however, with an increase in the thickness of the doors by 3-4 cm.

One of the popular ways to make soundproof doors out of ordinary doors has been known for a long time. The usual steel door or made of solid oak, it is enough to sheathe it with a dense fabric 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 level of a double door block.

Door frame installation method

To a large extent, the soundproofing properties of a door block with a frame and cladding depend on the method of fastening.

It is possible to radically improve the sound insulation performance by installing an internal wooden door with a cladding made of dense laminate with corrugated paper filler. You can use any interior door with a high level of noise and sound insulation resistance.

In theory, you can even install aluminum or plastic door of the usual type, this is not the point. The characteristics of the inner sheet do not particularly affect the ability to withstand noise and sound.

To double door possessed high soundproofing characteristics, three conditions must be met:

• The size of the air gap in the vestibule between the doors must be at least two thicknesses of the outer door;
• Outdoor and inner door without fail equipped with a soundproof seal;
• The common door frame must be installed using soundproofing materials.

Most manufacturers of entrance and interior doors complete door frames with a set of suspensions and anchors. This approach simplifies the installation of the door frame, but often degrades the sound insulation characteristics of the door unit.

In order for the soundproofing unit to fully resist noise, a more modern circuit is used. Firstly, the fastening of a wooden or MDF box to the doorway is carried out using silicone plugs and plastic dowels. Secondly, before foaming the slots, a thin strip of foil isolon is placed in the gap between the box and the wall, and the strip itself is additionally hung around the perimeter on a rubber or silicone cord. As a result, any vibration and impact noise is absorbed at the entrance to the doorway.

Installation of soundproof doors

One of the disadvantages inherent in all types soundproof doors, is the increased thickness of the wood or cardboard sheet. Most of the standard models with increased soundproofing characteristics are made according to the scheme with a three-layer cloth, photo.

The door blank is made from three panels of low density particle board to obtain high sound insulation characteristics. The outer surface is veneered with MDF and covered with a durable textured laminate valuable breeds wood. The box is made from chestnut or mahogany.

For your information! Such a canvas is called "FDB", produced in Belarus and, according to the manufacturer, is capable of providing very high sound insulation characteristics in the air at the level of 37 dB.

The only drawback is the high price of soundproof door blocks. The cost of one product is over 600 EUR. High noise insulation characteristics are achieved due to light cellulose fibers and an air gap. Truth, high level sound insulation is achieved by a significant increase in weight, the weight of the door leaf with a thickness of 43 mm reaches 40 kg.

Budget models of soundproof doors

Cheaper door blocks with improved soundproofing characteristics are made according to the traditional scheme:

• The frame of the door leaf is made of pine timber;
• External cladding - 8 mm thick MDF panels;
• A honeycomb filler with a curved surface is installed inside the doors.

The honeycomb can be filled with expanded polystyrene granules, cellulose and mineral fibers. As a result, the noise-insulating sheet at a cost of about 100 EUR provides a noise reduction of 22 dB.

Imported analogs of Turkish and Polish production use granules from silicate glass and a blowing agent. Such door leaves, in addition to high sound insulation characteristics, have increased resistance to heat.

Information about the nature of the filler and noise insulation characteristics must be included in the quality certificate for the product.

Doors with special soundproofing characteristics

As interior doors with increased level insulation, you can use a conventional metal-plastic model with a glass unit. Despite the use of aluminum and plastic, materials with low sound-insulating qualities, a canvas made of double-glazed window is capable of reducing noise by 20 dB, and a three-chamber one by 22-25 dB.

The option of a metal-plastic interior door block is very convenient for rooms with a high sound and temperature load. It could be doorway on the balcony, on open terrace or exit to the corridor.

For special cases, when the noise level exceeds 50-60 dB, experts recommend ordering the manufacture of a door leaf for doors according to individual project... Doors with high noise protection are made with the installation of three to four layers of a roll-on sound absorber. For example, it can be a compressed silicon fiber soundproofing mat. Sound insulation level is 45 dB, resistance to open flame front up to 20 minutes. The material does not cake and does not lose its characteristics over 20 years of operation.

Conclusion

One of the most effective ways the installation of a hinged panel made of foam materials on the door leaf is considered to provide a high noise insulation characteristic. A thin material of only 5 mm can improve the insulation of a conventional interior block by 40%. Porous rubber is finished with PVC film with the texture of wood, plastic or any other format, as a result appearance the door block remains virtually unchanged, and the noise resistance is enhanced.

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. Because of thin walls and the absence of insulating layers, you can sit on the couch at home and listen to what is shown on the TV from your neighbors. Few people may like such comfortable conditions, and the only correct solution would be sound insulation. As you know, any sound travels 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 it comes 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 windows 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 structure of the door leaf is 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 doors 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 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 soundproofing material is also influenced by the characteristics of the insulation. There are products that, with prolonged use, shrink, which means that after 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 for reinforcement will be additional installation of a pair 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 an old door, making it look attractive. Typically, the sheathing is attached to wood surfaces using 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. Simple wooden door with vinyl cladding disassembled quite simply and without special equipment. When to change the trim for metal products, then the procedure may 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 the appearance and 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 soundproof 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 stuff a sound-proof 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, you can most 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 against 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. Mats can be a good insulation option. 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 is much easier to perform if the canvas is removed. You need to remove not only handles and locks, you will 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 sound insulator along the entire inner part. 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 the event of damage to the face, it is necessary to 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 to prevent the dermontin from tearing. 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-performed 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 an abundance 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. main feature of such structures lies in the fact that on both sides they have decorative cladding, 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, a sliding mechanism is 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 separate layer is made of sound-insulating and sound-absorbing material, so that the finished fabric 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 and plastic foil. To be sure of the quality of sound insulation of interior doors, it is worth ordering the product from the manufacturer or from a trusted supplier.

How do soundproof doors differ from conventional models?

Along with the fact that the market offers a large selection of conventional interior designs, it is quite difficult to determine which ones are soundproofed. 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 at 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 you can immediately see a quality item 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 offered 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, 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 to isolate 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?

Soundproofing 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 soundproof doors in an apartment if the windows and walls do not have such properties. If you nevertheless decide to protect yourself from noise, then this should be done 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 provides it with a tight fit;
• Izolon 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 supplement 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;
• Establishment 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

Also, such simple devices will help to increase the effect of noise isolation:

• 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 with inside the box is poured with concrete. 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. 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 insulating capacity has been introduced. It characterizes only one design.

It is measured in decibels and is 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:

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

Noise isolation levels

Noise is a rather unpleasant sound to hear. It irritates the nervous system and 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 sheathed 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.
