The system uses XPS polystyrene extruded board (hereinafter referred to as extruded board) as the exterior wall insulation material of the building. When the building main body and the external wall masonry work are completed, the XPS special interface agent is applied on the bottom layer mortar. The stretched XPS extruded polystyrene board is bonded to the wall with a bonding mortar as required, and anchored with a plastic expansion screw.
Then, the polymer cement mortar is applied on the surface of the extruded board, wherein the alkali-resistant plasticized glass fiber mesh cloth is pressed to strengthen the protective layer of the crack-resistant mortar, and finally the decorative surface layer of the putty and the paint (for example, the decorative surface layer is a tile, Instead, use galvanized steel mesh and special tile adhesives and grouts.
Compared with the EPS system, the XPS extruded polystyrene board thin plastering exterior wall insulation system has the characteristics of higher strength, better thermal insulation performance and stronger gas impermeability. This system is a kind of relatively high-grade insulation subsystem. It has been widely used in construction projects with high insulation requirements such as cold areas, high-end buildings and cold storage projects.
