AAC Concrete Panels
Application
AAC concrete panels are also called autoclaved lightweight concrete (ALC Panels). AAC concrete panels can be used as partition board, cladding panel, roof panel, fireproof plate and so on in concrete construction industry, steel structure industry and civil buildings. ALC partition board can be used as separating wall, indoor compartment wall, bathroom wall, etc. ALC partition board is suitable for hanging objects like, air conditioner, water heater, heating radiator, etc. Therefore, ALC partition board is widely used in hotels, schools, motels, office buildings, etc.
ALC cladding panel is widely used as the external wall of each type of buildings due to good heat preservation performance and heat insulation performance.
