Name : Heat insulation sheet . AL/ Woven Cloth / Bubble/ Woven Cloth / AL Material Structure AL/ Woven Cloth / Bubble/ Woven Cloth / AL This is a new environmentally-friendly heat insulation material,which is soft light and easy to install,lt is made from aluminum foil and polyethylene by special machinery,lt has no odor and toxicity;lt not only overcomes the discomfort and environmental damage brought by glass fiber and epispastic materials,but canalso resist ultraviolet radiation that can penetrate through sheet iron,concrete,wood and other common heat insulation materals.This new heat insulation material not oniy hasgood 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 rloor,resist over 80% external heat from buildings,protect wall,resist thermal shock and sudden,etc. Characteristics: 1.No odor and toxicity ,environmentally-friendly; 2.Light,soft,dust free,fire retardant,easy to install; 3.Heat reflection,heat insulation,sound insulation,anti-radiation,anti-vibration,and shieding; 4.Moisture barrier,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.
