Soundproof doors for interior openings differ from standard entrance doors in many ways. Here and finishing, and the general complete set, and internal filling. Of course, their price becomes higher from this, but the level of comfort they create increases. With their help, it is possible to comfortably retire, relax calmly, and, or work in silence, if the environment is full of extraneous sounds. Good doors of this type will become a reliable anti-noise barrier and they are popular not only among residents of apartment buildings, but also among owners of large suburban real estate.

The product in question will easily become an indispensable element not only for living quarters, but also for any large office. The level of noise reduction will also depend on the design properties and its quality. The basic parts of this design are the box and the sash itself. The first is traditionally performed in a U-shape, which is then installed in the opening. Sheds and a counterpart for a lock or latch are attached to the box. The sash is not some simple single-layer sheet, but has a multi-stage structure. In particular, it includes:
The models under consideration can be hinged, i.e. when the sash opens outward from the room, or can be sliding, i.e. when the canvas moves along the wall. In the latter case, instead of canopies, it is necessary to install special rails, rollers are mounted on the sash, thanks to which the door moves. Some samples may include additional design elements, such as glass inserts.

For soundproofing in construction, special standards are provided, which are enshrined in the State Standard No. 26602.3 of 1999, Building Regulations 2-12 of 1977 and 2.08.01 of 1989. According to the indicators given in these documents, the noise level in a residential area should not exceed 30 decibels. Accordingly, it is possible to achieve this level qualitatively by soundproofing doors. Most modern models for interior openings, in principle, allow this bar to be reached, but only if their canvas has special structural properties, since various materials can be used, some of which are barely able to fulfill the established conditions. The average door option from the budget segment will only protect against sounds with a power of 18-27 decibels, which corresponds to the noise level during a quiet conversation of several people. However, one must also take into account the airborne sound insulation index (Rw), which increases the overall figure by 2-5 units. From this it is clear that if a non-standard noise situation is created, then a simple door will not be able to suppress the sound in any way.
Interior door leafs can be made from a variety of materials: glass, plastic or wood. The most popular options are solid wood or materials that imitate it. It is easiest to divide such models into two categories: hollow and full-bodied. In the latter, there are no voids in the structure. They can be made from solid wood, which will significantly increase the cost of the product (especially if you choose valuable species as wood, for example, oak). If the type of wood is not very valuable, for example, pine, then several plates from it are simply glued together, forming a solid shield without voids, which is sheathed with MDF on top.
IMPORTANT! To improve the soundproofing qualities of hollow doors, you just need to fill their internal cavities. Usually this filler is foam or mineral wool. It is also possible to use expanded polystyrene, special honeycomb cardboard, and other foamed substances.This amplification operation can even be done independently, using a synthetic winterizer from an old down jacket or any other soft insulation for this.
Qualitative characteristics in the field of sound insulation will depend on three main parameters:
IMPORTANT! In addition to the above factors, the fittings themselves and their quality will play a special role. If the hinges turn out to be rather weak, then the web may be skewed, which will form gaps that can transmit noise from the outside. And if the door handle has a large backlash (which does not guarantee tight clamping of the sash), then again a gap will appear and proper sound insulation cannot be observed.
The correct name for the door structures in question is “acoustic”. They are designed to minimize the amount of extraneous noise entering the locked room, as well as out of it. Their interior versions have a number of distinctive features:
It should be noted that in addition to the above features, the competent installation of the entire structure into the openings will also play an important role, which will also affect the creation of the desired acoustic climate in the room. At the same time, it is possible to increase the level of noise insulation by covering windows and walls with protective materials (this applies to rooms with a large area).
It is believed that the installation of acoustic doors is best left to professionals.To get the job done right the first time. If self-assembly is planned, then the main thing is not to make fatal mistakes. To do this, follow a few simple recommendations:
IMPORTANT! When installing fittings in the form of a latch or handle with a latch, it is necessary to properly make the inlet for the tongue. When it enters, no backlashes are allowed, the sash closes only gently, does not require the application of excessive muscular effort, despite the fact that the web is pressed to the right degree.

For interior doors in an office, apartment or private house, their visual appeal is essential. Finishing the sash is simply obliged to harmoniously combine with the overall interior. The most important quality is also durability, unpretentious care, and the overall strength of the element, which will not allow even small scratches to form on it.
When choosing soundproof interior doors, you should pay attention to the following factors:
This heavy solid canvas has a melamine surface and is characterized by increased sound insulation. The pine shell and durable MDF cladding make the door strong and extremely durable.

Behind a high-quality soundproof door, it is possible to freely listen to loud music, rehearse the performance of a musical group or joyfully cheer for your football team, without risking disturbing the peace of a loved one sleeping in the next room. However, it is worth remembering that the possibilities of soundproofing interior doors are somewhat limited for quite objective reasons, and if it is not possible to make complete insulation by installing professional acoustic doors, then you can try to negotiate with the “noise source”, for example, by sending him to take a walk outside.
