Sound insulation of the door with your own hands: step by step instruction

Good entrance and interior doors - not only aesthetics and home comfort. This is the absence of drafts and silence. But often such characteristics can boast only good and expensive designs. On models of the lower price segment, options such as sound insulation may not exist. But you can always upgrade the design with your own hands.

Sound insulation of the door is a simple process that will help create a real cosiness in the house or apartment. Let's look at how to do it.

Materials

In an ideal situation when buying, you must immediately choose a good noise-proof model. But if you did not get a good door, then you have to do it yourself. To protect the fabric from noise, various soft, loose or hard materials are used. Often they serve as a heater. Soft soundproof materials eventually settle. This is not the best way to affect the protection from noise.

It can also affect the appearance of the canvas (if it is the upholstery). Loose sound-absorbing substances are not always suitable. If the soundproofing of the door is done by hand, then for this there are several materials available. Good for protection against noise polystyrene. He does not miss the sounds and cold. It can be supplied in the form of granules or a liquid mixture. Also allocate sintepon. It is rather soft, has high wear resistance. Its main advantage is a low price. But to get a good result it is necessary to paste the sintepon sufficiently thick layer. Another inexpensive option is foam rubber. It is suitable for work on the upholstery of the door leaf, and as an internal filler. Also, with foam rubber, joints can be sealed.

Isolon is a more modernized foam rubber analogue. It has a high density and improved characteristics, but its price is an order of magnitude higher. Wool is widely used for soundproofing. It is sufficiently soft and widely used in the work on the compaction of voids, crevices and joints. Over time, this material can shrink. Also, mineral wool accumulates moisture well, but it is reliably protected from the rotting and multiplication of various insects. For work on soundproofing, foam plastic is also suitable. Sheets are often used, but the product is also produced in the form of granules. This is a good and affordable soundproof material, but it differs in average performance.

Preparation for works

Modern entrance doors can be of two kinds - with the internal upholstery and without it. If the product costs less than 15 thousand rubles, then the lining is easily dismantled. Door leafs without any finish inside are much safer. But they miss any sounds. Sound insulation of the entrance door must begin with the work on the dismantling of the shell from the inside. On most structures it is fixed on screws. On the old doors it can be mounted on decorative nails, so it's very easy to get rid of.

Still it is possible to meet door leaves, задекорированные a skin or a leatherette. If necessary, this decorative upholstery can be changed or left unchanged. It does not affect the level of sound insulation.

Dismantling of plating

Before dismantling the door structure, unscrew the handle and remove the cover plate. It is also desirable to dismantle the larva of the lock. This is necessary if it is installed secretly, but you can not do this. If the door is equipped with a push handle or other automatic closing systems, it is better to block them. Sound insulation of the door usually begins with the removal of the old decorative coating. On most metal structures, under the upholstery layer, it is possible to see the transverse elements from the profile pipe, fixed by spot welding, and the crookedly beaten crossbeams made of wood. If these components are already rotten, and the metal rusted, then they can be safely removed, and the steel is carefully cleaned with a sandpaper or processed with a zinc converter. Some models from the inside are covered with a sheet of hardboard. We also extract it.

Laying soundproof material

In most door models, mineral wool or felt is used as a sound absorbing material . All this is attached directly to the hardboard. Along with the available materials, you can use special tools. These are seals that are used in car noise insulation.
As the first layer, so that the material is not subsequently decayed, the web insulation is glued to the roll insulation "Schumanet". One of its sides has a special polymer-bitumen coating. Then lay mineral wool or styrofoam. Then you can pick up any material up to 5 cm thick. This should be the third layer. In the end, an additional layer of "Schumanet" is attached. Naturally, this method is not true, but in this way you can achieve maximum protection from noise from the entrance or from the street.

How and what to attach materials to the canvas

Since the soundproofing of the metal door is carried out using special materials, the approach to installation will be special. Installation should be carried out only after a qualitative cleaning of the surface of the blade. For its degreasing, it is recommended to use alcohol, kerosene or acetone. Sound absorbing materials are best installed using specially designed adhesives. You should not save on them. Sound absorbing plates and sheets should be as flat as possible to the surface of the metal sheet. This is important, because only so the door can withstand the temperature changes in the off-season and drafts. When choosing an adhesive, pay attention to ensure that it has a service life of more than 10 years. So you will not re-paste all over again in a couple of years. Each next layer is recommended to be stacked only after the previous one has dried completely. "Schumann" has its own adhesive tape, but there is no need to feed the special hopes - the composition on this film is not very reliable. Therefore, it is not superfluous to miss its main substance. To Schumann better fit to the surface of the metal, it is recommended to pre-warm it with a hair dryer for 20 minutes.

Seam processing

This is an important point. Without quality joint processing, the sound insulation of the door will not be complete. At joints, in places where sheets are joined together, it is recommended to seal and damp these areas. Ideal for this special sealant. With it, you can quickly process the metal front door.

Processing locks

This point should be given special attention. If the lock has an open structure, it is worthwhile to build these areas with soundproof materials. Clearances are easily filled with mounting foam. Do not impose too much composition. It has the property of increasing. As a result, the lock can jam. Instead of a foam, mineral wool or silicone sealants are good.

Completion of work

Now the soundproofing of the entrance metal door is almost finished. It is also recommended to lay the heater under the dermatitis. The hardboard can be installed on self-tapping screws even if it is attached using nails. Now it remains only to purchase door seals and install them on the box and door leaf. Also, close all the slots in the door unit.

Interior

Sound insulation of the interior door will help create maximum comfort and comfort in an apartment or house. But this process is performed a little differently than in the case of input structures. Here it is necessary to try to seal the joints. The canvases of such structures are rarely subject to serious modifications. To protect yourself from noise, you need to purchase and install a threshold. It must be combined with the door leaf when closed. On the perimeter of the door frame, it is recommended to glue the seal. It should be selected based on the size of the gaps along the edges of the fabric. If the sealant is not enough, then there is another option - the paneling with special panels. It is best to purchase immediately interior doors with sound insulation, for example, from MDF. Over time, noise absorbing materials can deteriorate and wear out. They are recommended to be updated periodically. Especially important is the position of the canvas. When the door is used, there may be distortions, which cause gaps. This breaks the protection against the penetration of noise.

Summary

Of course, you can immediately get good doors with good sound insulation, but it's expensive and not always possible. But if you make a little effort, you can get the same level of noise protection for cheaper door blocks.
