Steel aluminum heat insulation board compounded by two sides anti-aging nanometer aluminum film and color galvanized steel compounded by heigh-tech. The product has reflective insulation, ageing resistance, anti-corrosion, acid and alkali resistance of metal roofing materials.
Steel aluminum heat insulation board the outer aluminum foil layer, reflects the sunlight and infrared heat the matal plate surface , the infrared wavelength range 0.76-1.05 mm reflectivity of 75% to 100%, its high thermal effciency. Steel aluminum heat insulation board is two sides anti-aging aluminum film+nanometercompiex+center layer 55% color galvanized steel; Aging coefficient of thermal conducticity of nanometer membrane is 0.18%W/m.k, nanometer complex coefficient of thermal of thermal conductivity of 0.19W/m.k, In low temperature holding steel heat shield will not feel cold, steel aluminum heat insulation board using on building insulation performance is good.
