Phenolic Foam products for the closed pores of rigid insulation material, flame resistance has central air conditioning installation, fire burn, the surface was carbonized phenomenon only, it does not melt drip, not broken, the same type, no significant contraction of central air conditioning , do not emit toxic gases; central air-conditioning manufacturers with low water absorption, excellent water moisture barrier; low thermal conductivity; the construction is simple, the product of a hard material. Easy to cut, install, such as the use of the outer layer of aluminum foil folder tendons strengthen armor, can no external metal hard protective shell, the overall cost savings investment. Department of Housing has initially identified nearly 40 cities as "second five" energy-saving public buildings in major cities of central air conditioning production, requires each city to complete the transformation of the building area of ??not less than four million square meters in the next two years. According to the China Energy Conservation Association of Energy Service Accounting IPCC, currently the existing building area of ??430 million square meters, of which more than half the area of ??public buildings, energy compliance rate of less than 10%.
