In order to arrange the sound insulation of the ceiling in the dwelling, you can fix a variety of materials on the ceiling — polystyrene, flax pcquet, cork coatings, basalt cotton wool. The latter option is most often used. At the same time, cotton wool is placed in a profile frame and fucked from below with drywall.
Preparation of the surface of the ceiling
First of all, that — the sound insulation of the ceiling turned out to be of high quality, it is necessary to properly prepare a black ceiling. To do this, it is cleaned of dust, as well as thoroughly sealed with putty all the seams between the plates and the cracks. If you neglect this step, all subsequent work on isolation of the ceiling from shock and air noise may not be very effective.
Installation of the frame
Along the perimeter of the walls, at a distance of 15 cm from the surface of the ceiling, a marking line is carried out, strictly withstanding horizontal. At the same time, it is worth using the building level. Next, focusing on marking, the initial profile is attached. At the same time, they use dowels (step 40 cm). Then mark the main guides. The step between them should be 125 cm (1/2 of the width of the drywall sheet). The suspensions are preliminarily mounted on the lines. It should be used at the same time vibration output fasteners. This will reduce the level of shock noise. Next, the supporting guides are attached. The first bar will need to be installed at a distance from the wall in about a centimeter. This is necessary in order to prevent deformation of the surface of the gypsocraton in the future. During installation, it is best to use anti -vibration dowels. If there are no such at hand, you will have to be content with ordinary. After the supporting profiles are mounted, a new marking is applied and transverse trims are installed. The step between these elements is taken 60 cm.
Installation of cotton wool and drywall
All cells in the resulting frame structure are further laid by mineral wool slabs, the density of which should be at least 40. Then the structure is sheathed with drywall sheets so that there is a small distance between them. Next, the resulting seams are covered with putty and proceed to finish.
Work on the sound insulation of the ceiling ceiling is enough labor -intensive and technically complicated. Therefore, many owners of apartments still turn to specialists who, among other things, have materials more suitable for this purpose and fasteners.
