Phenolic board density
exterior phenolic board to the Ministry of Public Security, ministry of civil building external insulation system of fire prevention regulations. Applicable to new kinds of multilayer, high-level building energy-saving construction and energy-saving reconstruction of existing homes. Curtain wall and curtain wall building energy efficiency. Not bibulous, 24 hours soak bibulous rate is not greater than 3%. Permeability is insulation layer, can extend the life of the wall. Good insulation, low thermal conductivity, 0. 02 - 0. 029, energy saving can reach 50% 65%. Can be used as a fire belt, exterior wall insulation decorative sheet, is characterized by high flame retardant,. Stability, corrosion resistance, to adapt to the external wall, is not easy to shrink, don't break. Light quality, non-toxic tasteless, green environmental protection. Meet the design requirements specifications, density and thickness. Phenolic plate is used for the curtain wall insulation construction methods commonly used external wall insulation mortar bonding method or in combination with nail glue. Bottom-up from the beginning of the support part, with polymer glue cracking mortar, paste phenolic board on the wall. Bonding area should be greater than 35%, the first layer is greater than 50%. Outer sheath heavier, per square meter and nailed four to six insulation.
phenolic plate thickness, density according to the requirements of design, generally in the north of the Yellow River area should not be less than 4 cm, 50 kg/m3 density, in cold area should also be more appropriate.
