FRP door&window profile

(5)Green environmental protection: According to the department concerned test, the high quality glass fiber reinforced plastic windows and doors molding conforms to national compulsory standard GBl8584-2001 "Interior decoration Finishing material Wooden Furniture Deleterious substance To limit" and GB6566-2001 "Building material Radionuclide Limits the quantity" each item of deleterious substance to limit the quantity the target, formaldehyde projects and so on release quantity and soluble lead, cadmium, chromium, mercury is the standard limits the quantity 1/6~1/600, meets A classification of finishing material requirements, and the green environmental protection building materials product promotion condition

(2)Heat preservation and heat insulation: The glass fiber reinforced plastic molding thermal conductivity is low, makes the window frame thermal resistance value is bigger than other material window frame: The glass fiber reinforced plastic window frame's thermal resistance value is 9.96mk/w, plastic steel window frame thermal resistance value is 5.93mk/w, the hot room partition bridge aluminum alloy window frame's thermal resistance value is 0.16mk/w. And the glass fiber reinforced plastic windows and doors molding is the hollow structure, has the air thermal insulation layer, the heat preservation effect is better. The high quality glass fiber reinforced plastic windows and doors heat preservation performance surpasses the national standards GB8484-87 heat preservation performance first-level target.
 
   
 (3)The size is stable, sound-insulated is excellent: Glass fiber reinforced plastic molding thermal deformation temperature is 200, even if it will be under the hot sun not to distort for long time: Its linear expansion coefficient with building and glass quite, in the difference change between cold and hot temperature environment, not easy to have slit between the building and the glass, may enhance the glass fiber reinforced plastic windows and doors' sealing property greatly. In addition, the glass fiber reinforced plastic resin and the glass fiber composite construction's oscillation damping is very high, may amount to 26~30 decibels to the sound impediment.
   
(4)Anti-corrosive, anti-aging: The glass fiber reinforced plastic windows and doors to the inorganic acid, the alkali, the salt, the majority of organic matters, the sea water and the moist environment have the good resistivity, also has the resistance function regarding the microorganism, therefore besides the dry area, it also suitable for the rainy, the moist area, the coastal area and the chemical place. But it corrodes to certain metal's electrochemistry actually helplessly. PVC plastic steel windows and doors can bear moistly, the salt mist, the acid rain, but under the ultraviolet ray function, its macro-molecule chain will be break, thus causes the material surface to tarnish, the color deterioration pulverization, and the mechanical property will decline. Under the regular service condition, the glass fiber reinforced plastic windows and doors life span may amount to for 30~50 years, the aluminum alloy windows and doors life time is about 20 years, PVC plastic steel windows and doors life time is 15 years
   

 (1)The light quality excels in: The glass fiber reinforced plastic molding's density is: 1.8~2.0g/cm3: ; Approximately is the aluminum alloy 2/3: Its longitudinal strength above 350 MPa, the bending strength is above 260MPa, approximately is aluminum alloy 2 times, plastic steel 4~5 times. The glass fiber reinforced plastic windows and doors made up the shortcoming which the plastic steel windows and doors intensity is low and easy to distort.
