Insulation materials insulation sandwich panels used mainly in fiberglass cotton, scaffold Caigangyanmian sandwich panel with good thermal insulation effect. For external wall insulation board, effectively prevent the wall of the "cold bridge" phenomenon, Caigangyanmian sandwich panels, to achieve a better insulation effect. R15 insulation around 100mm thick cotton thermal resistance can be equivalent to 1m thick brick wall. Sound insulation sound insulation is an important indicator to assess residential, Color + light steel system installed windows are made of hollow glass, sound insulation, sound insulation up to 40 decibels; the wall by a metal frame, thermal insulation material composed of gypsum board, Anyang Caigangyanmian sandwich, its sound insulation up to 60 decibels. Health sealing performance: rock wool sandwich panel polyurethane seal on both sides of the assembly line production process, Jincheng Caigangyanmian sandwich to take advantage of the excellent water resistance of polyurethane products overcome the shortcomings of wool easy-absorbent deliquescence, in physics performance effectively extending the life of the product. Beautiful performance: interface with European standards for the design, the appearance of rounded and smooth, flat plate surface appearance, tight joints, reliable strength, effectively prevent cold bridges.
