Is it possible to make sound insulation of the ceiling? For this purpose, will serve a suspended acoustical ceiling. It performs several functions, it reduces the energy of the reflected sound absorbs noise and improves room acoustics. And as the sound-absorbing material used slabs of thin mineral fibers. It is important that they are porous.
Ceilings lined with foil absorb sound worse than their options with painted or fabric surface sheets, which have lots of microscopic pores. The space between the suspended ceiling and floor slab should also be filled with insulator without it, the design will transmit the noise from the apartment upstairs.
Suspended ceilings can be made of drywall sheets (GCR). They are usually not structural (load-bearing) elements of the building, and is designed primarily for problem solving of decorative finish and acoustic insulation of the premises. But thanks to the ceiling increases the fire resistance of load-bearing structures and ceilings.
Installation of ceilings must start during the period of finishing work when finished “wet” processes that can significantly improve the humidity in the room.
Fig. 1. Fragment of the ceiling of plasterboard (on a metal frame in a single level):
1—the attachment of the ceiling, 2 load— bearing profiles of a suspended pogaca; 3 – guide profiles of the suspended ceiling; 4 wall; 5—ceiling; 6—wall profiles;
a— distance (1000 mm) between the points of attachment of the suspension (1) to the ceiling; in— the distance (500 mm) between the support profiles; s— distance (1200 mm) between the main profiles; d is the distance (1200 mm) between the wall axis and the extreme main profile. The frame is mounted based on wall profile
In the General case the installation is performed in the following sequence:
applied to the wall mark the design position of the suspended ceiling frame,
mark the ceiling (basic ceiling) the location of the main fastening profiles or bars and fixing brackets;
