At present, the expanded vitrified microsphere thermal insulation system has been widely used in Sichuan due to its excellent fire prevention advantages and other characteristics. Cracks in the expanded vitrified microsphere insulation system can be divided into internal insulation wall cracks and external insulation wall cracks.
Cracks in the thermal insulation of expanded vitrified microbeads
Cracks in the thermal insulation of expanded vitrified microbeads are a common phenomenon. Because the cracks in the internal insulation wall are always exposed to the residents' view, there are relatively many complaints. Cracks in internal insulation walls mainly occur at board seams, around windows, at window corners, and at the junction of insulation boards and non-insulation walls.
Cracks in expanded vitrified microbead external insulation
Cracks in expanded vitrified microbead external insulation mainly occur in board seams, around windows, window corners, parapets, and between insulation and non-insulation walls. combination. From the shape of the cracks, they can be divided into surface network cracks, longer longitudinal, transverse or oblique cracks, local bulging cracks, etc.
