(2) the comprehensive performance improvement of housing. The use of precast concrete structure, can enhance the durability of residential. By using self insulation or internal heat preservation, the leakage and durability of external thermal insulation wall are solved, and the fire protection of exterior wall thermal insulation material is also provided.
