THERMAL INSULATING CONSTRUCTION MATERIAL EQUIPPED WITH HEAT REFLECTION FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide thermal insulating construction materials excellent in weight reduction and insulating suitable for roofing, enabling an optional color to color in them and abounding in versatility with high productivity at a low cost. SOLUTION: A reflective coated film 2 with at least one layer containing 2-70 wt.% of pigment having more than 30% of solar heat reflection factor (RE/NIR) in the wavelength area of 800-2100 nm is applied to one side of a metal substrate having more than 20% of solar heat reflection factor (RE) in the wavelength area of 350-2100 nm such as plated steel plate, aluminum plate, stainless steel plate or the like. A thermal insulating material 7 (for example, thin resin foam) is stuck on the rear side of the substrate 3.
