Members of one family in one way or another are faced with the problem of soundproofing of premises.
There are many recommendations on how to isolate windows that protect against outdoor noise, but inside you should install interior doors with noise insulation.
This is especially true in such premises as a bedroom or an office - that is, where silence is needed.
And some too "noisy" rooms, on the contrary, it is necessary to protect from other premises( this includes a cinema hall or a children's room).
The main feature of the proposed designs is the sheathing with special panels, which provide excellent noise-damping characteristics.

Features of doors with sound insulation
Interior doors with sound insulation can be made of materials such as fiberboard, plastic, metal and glass( and even a mirror), as well as wood.
The most popular variants are from wood and fiberboard, and from plastic and metal, sliding structures are most often made.

At the same time, plastic products and "shutters" made of aluminum rails are considered to be the most inappropriate options for providing soundproofing characteristics.
Also, the models made using shield technology( when the wooden frame is covered with sheets of fiberboard or MDF) are considered to be an unsuccessful design, since resonant voids are formed in them.
Significantly deteriorate sound insulation performance and glass inserts.
A from the wood massif are made interior doors with increased noise insulation.
Foil structures made of hardwood can reduce the noise level in the room by 20 dB on average.
Ready-made interior doors with good sound insulation are made according to the principle of "sandwich" and can have the following structural features:
- the panel structure must be supplemented with an internal filler made of cardboard sheets placed inside by the principle of honeycombs;
- if the project provides for glass, then it should not be single, but double or triple( a special glass unit is installed);
- good sound insulation protection will be achieved only if the gap between the box and the door leaf is minimal.
By the way, the noise reduction performance of the door structure will be higher the weight of it - more.
In addition, it should be borne in mind that the sliding interior doors with noise insulation will always yield to this characteristic swinging.
How to do it yourself?
Having installed interior doors with noise isolation, you can reduce the noise level in the room by 12-26 dB.
The same indicators can be achieved if the standard interior is equipped with appropriate materials.

These works can be performed by you yourself.
So, how to make the noise insulation of the interior door:
- between the wall and the door frame the cracks are carefully sealed with the help of a sealant;
- is used for casing on the side of noise penetration;
- filler can be batting, foam rubber, mineral wool, sintepon or else prefabricated soundproof panels glued to the base with special mastic;
- for decoration will suit dermantin, artificial leather and so on;
- on the perimeter of the door glued sealant or hollow profile rubber cord - so that the clearance between the door frames and the sheet does not exceed 1 mm;
- to reduce noise from under the door is installed special sound-absorbing sill.
A little differently, the noise insulation of interior doors with their own hands, if they have a sliding structure.
Here it is important to understand what type of sliding structures are being discussed.
The best sound insulating performance can be achieved if the doors move inside the wall( disappear in it).
The same options that move along the wall, it is difficult to soundproof, because they must be structurally large gaps that ensure free movement.

In the case of sliding products, soundproofing measures are as follows:
- , between the door and the wall, the gap should be reduced using a special plinth;
- between the ceiling and the door also reduces the gap due to special carriages;
- crevices between the canvas and the wall are minimized by special brush seals adhering to the platbands and the lath hiding the track.
Where to buy and how much is it?
Buy interior doors with noise insulation can be in specialized companies that produce just such sandwich designs.
In this case, as a rule, we are talking about monolithic modern products, more suitable for industrial style or high-tech design.
The cost of such designs starts from 200-240 dollars, and much depends on the level of sound absorption, and on the external design of the product.
On average, the price of interior doors with sound insulation is about 300 dollars. For this amount you will get an elegant piece of solid wood.
If your budget requires saving, you can install standard interior doors, the cost of which varies between 50-110 dollars, and then independently carry out their noise isolation.
