The main types of interior walls

In addition to careful attention to the external walls, especially to come up and towards the inside. All interior walls are basically divided in two ways. The first sign: the implementation of its functions - bearing and curtain, mezhkvartirnye and interior. It is based on the purpose of walls depends on their requirements. The second sign: construction - frame walls and billboards. In framing the walls of the bearing wall is a skeleton. It consists of frames, studs (lower, upper), cross-bars and struts. To stand not caved in the side, use a square timber. All the elements as a carrier operating in panelboard designs. The wall in this design is a frame consisting of uprights, which are connected the lower and upper zones. Sheathing prevents sag resistant. On the bearing and curtain walls is to say the following. Stability of the structure provide load-bearing walls. They distribute all the vertical and horizontal loads. In contrast to the load-bearing walls, curtain bear only its own weight, thus not affecting the stability of the structure. Interior and mezhkvartirnye wall separating the interior of each other. Their main function - protection against noise, heat insulation, and fire safety. Sound insulation properties of the interior walls. Mass walling affect the propagation of sound waves. Therefore, the lack of wooden structures is their low weight, and hence poor sound insulation. In particular, the unit weight of concrete - 2300 kg per cubic meter. And the tree - only 400. Because of this wooden wall will be five times thicker than concrete. And it is natural to be unwise. A soundproof concrete walls is 49db. And wooden 30dB. That clearly does not meet the necessary protection from the noise. Soundproofing interior walls must be at least 40 dB. But the plain wooden wall it can not provide. But if it is divided into two parts, the sound insulation will increase. They are even more enhanced if the cavity between the two parts to fill fibrous material. Very well suited gypsum boards (thickness from 9 to 18mm). Do not want the wall was thick, it will worsen its performance. Strong influence on the level of sound insulation of interior walls have adjacent structures.
