(AL/BUBBLE/AL) This is a new environmentally-friendly heat insulation material , which is soft, light and easy to install. It is made from aluminum foil an polyethylene by special machinery. It has no odor an toxicity; it not only overcomes the discomfort and environmental damage brought by glass fiber and epispastics materials, but can also resist ultraviolet radiation that can penetrate through sheet iron, concrete , wood and other common heat insulation materials. This new heat insulation material not only has good insulation, heat-reflection insulation and anti-radiation functions, but also has good moisture-barrier, heat-preservation and energy-saving functions in housing construction roof, wall, and floor). Function: Can be installed on roof, wall or floor, resist over 80% external heat from buildings, protect wall, resist thermal shock and sudden cold, etc. Characteristics: 1.Light, soft, dust free, fire, retardant, easy to install, 2.Heat reflection, heat insulation, sound insulation, anti-radiation, anti-vibration, and shielding, 3.Moisture, bond odor and to xicity, environmentally-friendly, 4.Larrier, sun-proof, waterproof, good sealing property, heat preservation, energy saving¡, 5.Summer:moisture barrier, sun-proof, heat insulation, saving energy consumed by cool air conditioning, 6.Winter:heat preservation, central heating saving, and remarkable energy-saving effect. Usage: 1.Roof, wall, floor, 2.Shells of air conditioner and water heater, 3.Protective coatings of water pipe and ventilating pipe. 40*1.5.
