"cold block" foam shading screen

During heat transfer process including thermal; convection and radiation in three ways. The general screens have solved thermal insulation of convection and radiation two problems. This product has used a further development of PE foam insulation layer(K=0.03kcal/mh). The material is non-toxic, weather-proof and environmental friendly. This is like from a single-screen into a thick screen in order to solve the problem of heat conduction and reaching a super energy saving effect. Warranty: five years
