11 advantages of FRP doors and windows

FRP (FRP fiber reinforced plastic) profiles are made of glass fiber and its products as reinforcement materials, unsaturated polyester resin as basic materials, and the profiles are produced by pultrusion process, and then assembled into doors and windows. FRP doors and windows are another generation of new doors and windows after wood, steel, aluminum and plastic. Fiberglass doors and windows have the following excellent characteristics:

(I) light weight and high strength

fiberglass profiles have a density of about 1.7, which is 4 ~ 5 times lighter than steel, but a great strength. Its tensile strength is 350 ~ 450MPa, which is close to ordinary carbon steel, with a bending strength of 388mpa and a bending modulus of elasticity of 20900mpa. Therefore, steel lining is not required for reinforcement. "Fangyun" brand fiberglass windows have been tested, and their wind pressure resistance reaches 5.3kpa, It exceeds the level of Grade 8 in the international gb/t7106-2002 standard

(II) energy saving and thermal insulation

the thermal conductivity of FRP profile is 0.39w/m · K, which is only 1/100 ~ 1/1000 of metal. It is an excellent thermal insulation material. In addition, the FRP profile is an open web structure, and all seams are sealed with rubber strips and wool strips, so the heat insulation effect is remarkable. After testing, the heat transfer coefficient of glass fiber reinforced plastic casement window (single frame double glass window) k0=2.2w/(㎡ · K), which belongs to the level 8 in the national standard gb/t8484-2002; The heat transfer coefficient of glass fiber reinforced plastic casement window (single frame three glass window) k0=1.8w/(㎡ · K), which belongs to the level 9 in the national standard gb/t8484-2002; According to the provisions of relevant international specifications such as ISO for glass fiber reinforced plastic casement windows (single frame three glass windows, low radiation glass), the working conditions of the heat transfer coefficient and the change of the experimental machine must be within the range of room temperature from 10 ° C to 35 ° C, k0=1.3w/(㎡ · K), which belongs to the level 10 in the national standard gb/t8484-2002

(III) good sealing performance

in the assembly process of FRP doors and windows, the corner treatment adopts the adhesive and screw connection process, and all gaps are sealed with rubber strips and wool strips, plus the special profile structure, so the sealing performance is good. After being tested by the national construction engineering quality supervision and inspection center, Beijing construction hardware plumbing product quality supervision and inspection station, and Beijing Construction Engineering Quality Inspection Center, the air tightness has reached the national standard gb/t, becoming an important new material industry base in China, reaching the level of grade 5 in the 7107-2002 standard; The water tightness reaches the level 3 in the national standard gb/t7107-2002

(IV) health, green environmental protection and remarkable energy saving effect

the test results of FRP door and window profiles meet the index requirements of building main materials in GB6566-2001 radionuclide limits for building materials. The test results are 0.2, internal exposure index is 0.2, and external exposure index is 0.2

(V) good sound insulation effect

according to the inspection of the national construction engineering quality supervision and inspection center, the weighted sound insulation volume RW of "Fangyun" brand fiberglass double glass and three glass window air acoustic meter reaches 36dB and 39db respectively, and the sound insulation performance grade is level 4

(VI) corrosion resistance

FRP is an excellent corrosion-resistant material, which has good resistance to acid, alkali, salt and most organic substances, seawater and humidity, and also has resistance to the role of microorganisms. This characteristic is especially suitable for the treatment of coastal areas with rainy and humid conditions and the modernization of China through great reform, as well as places with corrosive media
