Environmental thermal insulation materials, made of aluminizer and polyethylene through special mechanical processing, are soft, portable, tasteless, nontoxic and easy to install. The polyethylene layer can be set with multi-layer of polyethylene bubbles whose selectable diameters range from 8mm to 25mm and selectable height between 3mm and 5mm. Various colors or fire-proof materials can be added to bubble materials. The outer protective agent layer can be coated with paints or compounded with polyethylene of various colors. There are three ways of heat conduction: Radiation, conduction and convection. In these ways, our products not only solve the hazard of the environment and the uncomfortableness of the body brought by original glass fibers and foam materials but also prevent the ultraviolet rays from penetrating iron sheets, concretes, woods and normal thermal insulation materials into the room. The combination of the reflection of aluminized materials, heat property and polyethylene materials not only endow our products with excellent insulation, heat reflection, thermal insulation and counter-radiation, but also enable our products to enjoy wide application in building houses (such as the roof, wall and floor) with good moisture resistance, thermal protection and energy saving. Function: Our products can be installed on the roof, wall or floor, with the effect in protecting buildings by insulating over 80% of heat, protecting walls and withstanding temperature shock or drop.
