What materials should be used for building energy saving? Why?
Rock wool is a selection of basalt or diabase as the main raw material, made by melting high temperature inorganic artificial fiber. Rock wool products have good thermal insulation, heat insulation, sound absorption, heat resistance, non combustion, and good chemical stability. Rock wool used for exterior walls of buildings. There are three forms of insulation: internal heat insulation, central sandwich insulation and external insulation.
Energy saving materials are widely used in building energy saving materials development and promotion in China. They have significant social, economic and environmental benefits, with great potential. At present, China's common energy-saving insulation materials are mainly rock wool, glass wool, polystyrene foam, cement, polystyrene board, silicate composite insulation mortar.
Glass wool is second kinds of products of mineral wool, with silica sand, limestone, fluorite and other minerals as the main raw material, by melting method and centrifugal method, using flame or high energy gas blowing process, the molten glass liquid made of inorganic fiber. Glass wool products have good thermal insulation, heat insulation, sound absorption, non burning, corrosion resistance and other properties. They are widely used in building, piping, storage tanks, boilers, aircraft, ships and other parts of the insulation, heat insulation and sound absorption.
