Characteristics: 1) Odourless, non-toxic and environmentally-friendly 2) Light and easy to install 3) Moisture-proof, waterproof and good sealing property 4) Light reflection, heat insulation, sound insulation, anti-radiation, shockproof, heat preservation and energy saving. Usage: 1) Roof, wall and floor 2) Shell of air-condition, water heater, high temperature furnace 3) Protective coating of water pipe and ventilating pipe We combine aluminum foil which has the characteristic of heat and light reflection with bubble sheet made from LDPE. Applying to house construction area (roof, wall and floor), the product can keep over 80 percent of energy out of the building and protect the wall from the damage of great change of temperature. It can also greatly reduce the harm caused by ultraviolet ray penetrating iron, cob wall, wood wall and ordinary insulation materials, and provide functions of heat reflection, heat insulation, anti-radiation, heat preservation and energy saving.
