This is a brand new environmentally-friendly heat insulation material which is soft, light and easy to install. It is made from aluminum foil and polyethylene by special machinery. It has no odor and toxicity. The polyethylene bubble between the aluminum foil can be more than one layer and can be made with different colors and fire retardant. Besides, the diameter of the bubble can be ranged from 5-25mm and the thickness of it can be ranged 2-7mm. The outer layer also can be printed with different colors or laminated with polyethylene. It has three thermal conductivity methods that are as follows: radiation, conduction and convection. We get patent (patent No. 2009 2013 3016.6) on this new heat insulation material which not only overcomes the discomfort and environmental damage caused by glass fiber and foam material but also avoid damages caused by  ultraviolent radiation that can penetrate through sheet iron, concrete, wood and other common heat insulation material. The special lamination of polyethylene and aluminum foil which has good function on reflecting light and thermal makes the heat insulation not only has good functions on insulation, thermal reflection, heat protection, counter radiation but also has good functions on moisture proof and heat insulation and energy saving when used as building material (roof, wall and floor etc.)
