What is the material of the frame? Board, gypsum board Brick wall Or what is the steel keel?
The general frame structure, the wall thickness is not large. Please confirm your wall thickness.
If you want to do the partition wall, at least the thickness of the sound insulation at least 100 or more, you want to improve the sound insulation, then increase the thickness. Therefore, the thickness of the original wall if it is about 200, the remaining space its use value is too low.
In this case, the wall can only use light steel keel gypsum board, filled with sound insulation cotton process. This is the smallest thickness of the process. Total thickness of 100.
Gypsum board wall, the standard process practice in place, is no problem, you said the cracks, to the time, most of the material is not up to standard, the process is not standardized.
Sound insulation from the best sort down: hollow brick wall, gypsum board noise wall, wood wall (no such process).
From the stability of the wall, the long row is also the case.
It is best not to use gypsum board, because the cracks are sooner or later, the sound insulation is not good, unless you buy absolutely first-class materials and construction with absolutely first-class technology, is actually impossible
It is recommended to use hollow brick to do the wall, more reliable, practical, that is, the wall is a bit of a waste of space, if you have to hang on the wall and the like, but also consider a little ordinary red brick, hollow brick wall hanging things unreliable
A wall that separates the interior of the building. Do not load the wall, the general requirements of light, thin, with good sound insulation performance. There are different requirements for the walls of different functional rooms, such as the wall of the kitchen should have fire resistance; bathroom partition wall should have moisture resistance
