Glassfiber Reinforced Plastic (hereinafter as GRP) is one kind of new energy efficient building material. It is hollow in double sides and furnished with plates, chooses glassfiber as main material, treated by the technologies of light reaction and polishing. Besides common functions of high strength and wonderful lighting performance, GRP possesses some special features. Firstly it is energy-saving and environmental-friendly; meanwhile, GRP is one kind of heat-resistant material, and is also insulated against noise. Owing to all these advantages, in western countries, it is widely applied to construction line, such as door & window industrial line, factory building, gymnasium, shopping center. And also used as lighting band, partition panel and acoustic baffle, etc. In view of its energy-saving function, GRP can be used to replace traditional building and lighting materials (sandwich panels etc.) to cut down on building energy consumption. As a result, GRP enjoys a promising market. GRP is one kind of special-constructed panel, which is made from glassfiber, URP and other additives, solidified by special UV-light. The features are as follows. Heat-insulating property. The K (heat transfer coefficient) is small as 2.0W/m2K. According to the test report issued by National Center for Quality Supervision & Test of Building Engineering (No.: BETC-QC1-2009-304R, refer to GB/T8484-2008), the result shows GRP of thickness of 50mm, K is 2.0W/m2K.Fire resistance: class B. According to the test repot issued by National Center for Quality Supervision & Test of Fire Equipment (No.: Zb200921913), refer to GB8624-2006, the result achieves class B.Smooth surface, up to 85% in light transmittance. According to the test report issued by National Center for Quality Supervision & Test of Building Engineering (No.:BETC-QC1-2009-305G), refer to GB/T2680-1994, GRP of thickness of 50mm, the transmittance is up to 85%. In sunny days, the illumination indoors can reach to 1000 lux. Refer to DIN 5035, the illumination in public place just needs 500 lux, and 200 lux is enough in workshop. Though it is high in transmittance, light pollution is not existed.Sound isolation: 28dB. According to the test report issued by National Center for Quality Supervision & Test of Building Engineering (No.:BETC-QC1-2009-304S), refer to GB/T50121-2005, GRP of thickness of 50mm, sound isolation is 28dB.Wonderful mechanical performance, which is shown in high elasticity and impact resistance. According to the test report issued by National Center for Quality Supervision & Test of Building Engineering (No.:BETC-QC1-2009-305DA), refer to GB/T9962-1999, result shows the vertical flexural strength is 131MPa, the lateral one is 124MPa, and the bending strength is more than 80MPa.Long service life: at least 30years. GRP enjoys good performance in light and UV light resistance, and passed long-time exposure experiment.High safety- hard to broken. Those doors, windows, curtain walls, partition panels, etc. used commonly in public areas, industrial plants and warehouses presently can be replaced to avoid maintenance in winter.Light in weight: GRP of thickness of 50mm, it is 6.8Kg/m2 in weight.It is of no pollution, and has good performance in erosion resistance (oxidation, acid, alkali, salt, oil and grease resistance). If destructive fire happens, GRP will be burned to be water, co2, co and dust, exclusive of nitride, sulfide, halogen or heavy metal. The product of combustion is low in toxicity, even lower than the one of pine, the result of smoke toxicity test is class ZA3.Due to the particular layer, which is of lighting and non-transparent, GRP can separate outside sight to ensure confidentiality in some special fields, such as military affairs, technology, etc.
