【Abstract】 A new type of thermal insulation material has been developed. It can be used to cover sun-light greenhouse at night instead of straw-curtain. This is a kind of compound material. Its heat insulation and preservation effect is better than straw-curtain’s. It has characteristics of light weight,waterproof,toughness, saving effort, and so on. The price is appropriate.
