Building energy-saving materials are materials used to reduce the energy consumption of buildings, including: plastic steel energy-saving windows with hollow coated glass, UV protection, outdoor noise isolation, and indoor heat in winter; external wall insulation system materials, used Reduce energy consumption in buildings and eliminate heat island effect; indoor wall tile veneer environmental protection materials are used to avoid pollution and reduce indoor cooling and heating energy loss. Buildings using these materials can achieve the effect of “warm winter and cool summer”, which is both energy-saving and comfortable.

Building energy-saving materials are roughly divided into two parts: wall insulation materials and energy-saving door and window materials.

There are many kinds of wall insulation materials, according to the fire rating, Class A is non-combustible materials, mostly inorganic insulation materials, such as vitrified micro-bead insulation mortar, rock wool board, glass wool board and so on. B1 grade is a flame retardant material, mostly organic materials, and a relatively large amount of flame retardant, such as polystyrene board, extruded board, phenolic board, polyurethane board, etc., is added. B2 grade is a flame retardant material, also known as flame retardant material, mostly organic insulation material, adding appropriate amount of flame retardant.

If the insulation effect is divided, the extruded board, polyurethane and phenolic board have the best heat preservation effect, and the polystyrene board and rock wool board are better, and the vitrified microbead insulation mortar is inferior.
