Can the whole wall of the high-rise building be made of grey insulation bricks?
As can be seen from the picture, the aerated concrete block should be 200MM thick. According to the regulations, it is possible because the building is a frame structure.
If the frame structure, it may be so. What is the length of the whole wall? If it is longer, it is necessary to make a constructional column; if the hole is larger, the edge of the hole needs to be made into a border or a constructional column; if the entrance is small, the edge of the hole is about 300mm and needs solid bricks to build better. South wall thickness can be about 190mm, plus plastering design value of 200mm. Personal comments for reference!
