Luoyang Yu Industrial Co., Ltd. to you about polyurethane insulation board: polyurethane insulation board advantages: effective thermal insulation due to the thermal conductivity of the blowing agent used in the polyurethane is much lower than that of air (good thermal insulation properties) external wall insulation board, so rigid polyurethane foam spacer Thermal performance is superior to those materials containing only air, such as: mineral wool, fiberglass and polystyrene. Moreover, its unique closed cell and high resistance to gas diffusion makes these have superior long-term insulation properties, its thermal insulation properties of sustainable 20 - 50 years or more; excellent corrosion resistance of polyurethane foam closed pore structure and surface material used, it has superior resistance to air and water gas properties, and it can be made at the time of forming the mosaic cement foam insulation board connection structure, easy to assemble later. Luoyang Dayu Industrial Co., polyurethane insulation board tells you: it does not require additional insulation moisture phenolic insulation board, save a lot of trouble laying insulation. These properties are other insulation materials can not simultaneously possess; wide, lightweight, thin wall due to the rigid polyurethane foam also acts as a structural material, making the overall structure is light weight, span, the advantages of high load. Compared with other insulation materials, polyurethane foam has the best thermal insulation. Rock wool insulation boards, large Yu Industrial (certified), Shanxi insulation board provided by Luoyang, Henan Industrial Co., Luoyang, Henan Industrial Co., Ltd. (www.lydayushiye.com/) is Luoyang, interior paint leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Industry leaders in the Great Yu with the staff warmly welcome all inquiries negotiations to create large Yu Industrial better future.
