Product Features:

1. Easy installation: Lightweight and compact, weighing only 3.7 kilograms per square meter. It saves time and effort during transportation and installation and is not limited by seasonal weather and geographical conditions. This not only accelerates the project’s progress but also saves construction costs.

2. Waterproof and moisture-proof: The excellent self-structure and compact interlocking slot installation method of the panels prevent structural damage caused by rain, snow, and freeze-thaw cycles, and eliminate water seepage and mold formation.

3. Seismic resistance and crack prevention: With its lightweight and high strength, as well as excellent impact resistance, it not only reduces the self-weight burden of the building itself but also greatly reduces the impact of earthquakes on the structure.

4. Thermal insulation: Compared to traditional exterior wall insulation materials, the exterior wall has excellent cold resistance and thermal insulation performance, significantly reducing heating and cooling energy consumption.

5. Fireproof and flame retardant: Through special treatment, it has good fireproof and flame-retardant properties, ensuring safety.
