Hollow brick, because it is relatively light, will not cause floor cracking. In fact, there are many other partition materials, including light steel keel gypsum board and steel wire mesh, which are relatively light and save space.
Generally speaking, brick walls should be built with 1/2 bricks during home decoration. If hollow bricks are used, the wall width 120 thickness includes painting. The main advantage is that the weight is light, which is 2/3 of that of the common 95 brick wall. It will not bring too much burden to the structure of the house itself, and the sound insulation effect is acceptable, because the holes in the hollow brick have sound insulation effect. Relatively speaking, consider the wall thickness of 95 bricks and hollow bricks.
