The ultra-thin insulation board is made of inorganic fiber core material with high resistance gas composite thin films by vacuum packaging technology. The core material is the choice of inorganic insulation material made of plate, high strength, good flatness and stability. The products derived from the most advanced refrigerator insulation to avoid air convection heat transfer, thermal conductivity of a significant reduction can be achieved 0.006W / (MK) is the world's most advanced and effective thermal insulation materials. The promotion and application of the technology in the field of building wall insulation, will be the development of building energy efficiency play an important role.
