Interior doors are installed to separate space in an apartment or house to certain zones, but also perform another important function - isolate the room from foreign sounds. Noise is one of the problems for a person hindering a comfortable life. And such premises in the apartment, like a children's room, a bedroom, a working office, require absolute silence inside.
Soundproofing of interior doors will allow maximum comfort. But manufacturers produce ready-made models that have increased noise insulating characteristics. Consider their main species, and also deal with the question of the right choice.
Noise and regulations
Sound insulation is indicated in detail in regulatory documents. So, it is GOST 26602.3-99, SNIP II-12-77, SNiP 2.08.01-89. Based on the numbers in these documents, the noise level in the residential premises should be no more than 30 dB. The noise applies through the walls, but if the doors soundly insulated, then the apartment will become much quieter.
Most modern interior doors meet the requirements specified in the regulatory documents. The only thing that should be considered when choosing is the design features of the canvas. Different models of doors are equipped with different soundproof systems. For their manufacture, various materials that have a certain level of noise absorption can also be applied.
Features of noise insulating doors
The ordinary door is capable of protecting from external noise to 30 dB. However, if there is a need to enhance the soundproofing of the room, you need to purchase and install a special door. Externally, the "quiet" canvases are practically no different from the standard, and otherwise they are completely different. Inside such doors, noise absorbing materials are laid.
In the production of interior doors with sound insulation, apply:
- array of wood;
- Warm plate;
- plastic, PVC panels;
- metal (more often aluminum);
- double glass.
From natural wood, most often produce ordinary swing doors inside which noise insulating material can be laid. Sliding blocks are made of plastic or metal, but they have the weakest characteristics of sound insulation. Also low indicators for noise protection are characterized by panel models made according to old technologies when the frame is trimmed with chipboard or MDF. Inside such cloths there is a space that resonates when exposed to sound waves.

From the array of wood
For the manufacture of noise insulating doors, natural wood is most often used, and this is one of the classic solutions. The design of such a canvas is predominantly swing type. Only those wood breeds that have a sound insulation level up to 32 dB are used. Such indicators are characteristic of coniferous rocks, as well as cherry, oak, ash.
On the characteristics of the door directly affects the thickness of the lumber and the type of filler, which is located inside the canvas.
Doors of a panel type
Characteristics of shield doors are significantly higher than other varieties. But they are not securely protected from extraneous noises. Soundproofing abilities depend on the structural features of the canvas. The main role is played internal filling, the presence or absence of a seal, as well as accessories.
In the shield doors as a filler applies cardboard in the form of bee cells. This solution allows you to qualitatively improve the soundproofing level of the unit. This is due to the fact that the elasticity of the cardboard is less than that of the wood. The sound from cardboard is distributed and reflected noticeably weaker.
The soundproofing level in such interroom doors is quite high. It is possible to improve the properties using an additional wooden frame around the perimeter of the canvas, a special thoroughtle, thickened platbands. These elements allow you to completely eliminate the noise that fall into the room through the doorway.
An excellent solution to additionally sound the canvas, there will also be a rubber seal.
Folding structures
Among the range of interior doors with noise insulation can be found and folding aluminum models. The degree of protection against noise they have low. Product data most often have a roller blind design. So the doors harmonica are made.
Aluminum is too weak for serious sound insulation. Metal is very well spent any sounds and door blocks from it are little suitable for creating comfort in an apartment or house. But the folding door is capable of providing silence if it is made of wood.
Despite the available price, the folding wooden door will provide a greater level of silence than aluminum analog.
Doors with glass
The glass door leaf itself is not able to provide a decent level of protection against noise. But there are models from sandwich panels with plastic facing. A good solution will be the door with a glass - enough double glass package for comfortable stay indoors.

Good sound insulation features have wooden doors with glass inserts - they benefit even in deaf products from the massif. However, the glass thickness should be at least 7 mm.
Noise-insulating materials
Internal filling of doors from the wood array, MDF and PVC has certain features. The degree of sound insulation of such canvases will be directly dependent on the type of filler, which was used in the manufacture of structures.
In most models, high sound insulation are achieved using the following acoustic materials:
- Corrugated cardboard is one of the budget materials with a weak degree of noise absorption, with time losing its properties.
- Mineral wool - fire-resistant filler, providing a good level of sound insulation of the door leaf. However, such material often gives shrinkage and dissipates.
- Foam plates - they have high sound and heat-insulating characteristics, are not deformed over time, but fire hazardous.
- Foamed polyurethane is perhaps the best, but also an expensive option. The filler sounds well the door canvas well, has a high resistance to fire.
Additional accessories for sound insulation
To the level of insulation from the noise of interroom doors and the box was even higher, manufacturers use various technological accessories. These are flexible seals and smart thresholds. Consider in more detail the last option.
The "smart" threshold is made of rubber. The task of this element is to reduce the gap between the floor and the door web, while ensuring easy closing and opening. This threshold not only increases comfort when operating, but also significantly improves sound insulation, becomes an obstacle for drafts.
The smart threshold is attached to the bottom of the canvas. When the door opens, it rises. When closed, the threshold is lowered, and then the lumen between the floor and the door does not remain.

Tips for choosing and other recommendations
In modern interiors there is a need for the same modern door canvases. But glass solutions, although they have a stylish design, the sound insulation level is the lowest. Good "extinguish" the sounds are capable only natural solid wood - an array. If financial capabilities allow, it is better to choose this option, if not, it takes exactly something wooden, then stop your choice on MDF models.

Choosing a door block with filling, it is necessary to clarify the material that was laid inside. Mineral wool for sound insulation is rarely used. A good alternative - basalt stove (it is often inside the entrance doors). This stove has excellent sound-absorbing characteristics.
The hollow blades made of conifers will lose even plastic - the air inside will perfectly spend sound. In this case, it is recommended to open the canvas and make sound insulation with your own hands.
Successful options
The ideal option today is the doors from sandwich panels. The finish is better to choose PVC. The thickness of such a noise insulating door can vary from 18 to 45 mm. On sale there are both deaf, smooth, glossy doors and more aesthetic with stained-in inserts and other decorative elements.
It is also recommended to pay attention to the door coupe. For sound insulation, they are much better than swinging canvas. There is no gap between the opening and the door block at the top, so below. But when choosing, you should give preference to expensive models, since budget solutions often become the source of noise during their operation.
Products from natural materials are always well coped with their tasks. Doors made of wood massif, at least from expensive oak or cheap pine, are distinguished by high sound insulation. The effect of noise absorption is achieved by both the properties of wood and the thickness of the canvas. Such doors will also impress their massiveness and spectacular appearance.
