Building energy efficiency is a rigid polyurethane foam is one important application areas. Many countries in the world energy consumption in housing construction are clearly defined. This provides for the rigid application of energy conservation in buildings. Now, some countries, the foam in the construction aspects of the total consumption has been ranked first. Such as the United States, rigid construction in 1996, accounting for the amount of foam 49% of total consumption, household, commercial refrigerators and other equipment accounted for only 23.5%. Rigid polyurethane foam is the roof, ceiling, wall panels, flooring and other parts of the ideal material for energy-saving insulation. Especially when the thermal insulation performance requirements of the higher requirements of the thinner layer of thermal insulation in order to increase the usable area of the building, processing, construction, and maintenance requirements under the more convenient, in particular, significant advantages of polyurethane. 


 At present, high-tech companies such as vibration benefit in the development and application of strong polyurethane foam exterior insulation and bulk insulation technology for engineering practice. Zhen Li solvent-free polyurethane rigid foam insulation exterior coating technology developed by Beijing Zhen Li high external wall insulation is one set of technologies. The technology uses the site to the main spray polyurethane foam insulation, to take ZL Adhesive Polystyrene insulation and supplementary insulation slurry leveling, decorative layer can be used for decoration such as paint or tile. 


 Shenzhen Construction Bureau plastic foam insulation materials plant belongs to the industry. The main production extruded polystyrene insulation boards (XPS), is the China Plastics Processing Association and the Environmental Protection Agency set out the existing "white pollution" of the alternative products have industrial restructuring, promoting industrial upgrading, the maximum out of 2010 foam industry significance of ozone-depleting substances. Energy-saving products in the new insulation extruded insulation board and new composite panel research and development, production and sales in one of the professional company that has successfully developed a variety of new extruded insulation board composite plates, and has been successfully applied to the building wall body and roof, cold storage, refrigerated trucks, communications, furniture, mobile homes, HVAC, cleaning and other industries and products, and customers alike. 


 The company's insulation board (XSP) named Paul Green board is through a special process of sheet metal forming a continuous extrusion foaming, the surface of the dura mater smooth, and the internal structure of the completely closed-cell foam, honeycomb structure, the formation of polar excellent insulation, low thermal conductivity, high compressive strength, non-absorbent, breathable and strong, corrosion-resistant, not degradation, EPS and other characteristics and strength than other materials, insulation, air infiltration, water resistant with large improved; in the flooded conditions, can still maintain its integrity and the compressive strength insulating properties, is the roof construction, roof, wall, underground, cold storage, the new highway construction and other projects inexpensive materials.
