It is a technological film with high-purity aluminum and ALGC combined to increase tensile and tear strength. It helps to save energy from heating and cooling through 95% high reflectance and 5% low emissivity. The high-strength aluminum membrane that breathes can serve as a moisture-permeable waterproofing agent to discharge internal moisture to the outside and prevent external moisture from entering the inside. In addition, Blockprime has achieved the highest grade of A1 in the test environment, which is based on the domestic non-combustible standard test and the European fire resistance test EN 13501-1. The A1 grade means an eco-friendly construction finish that does not spread flames and does not emit toxic gases in case of fire.
