Fiberglass doors and windows are known as the international wood, steel, aluminum, plastic after the fifth generation of doors and windows products, it is both solid aluminum, steel doors and windows of the insulation, corrosion, and its own unique features: colorful , Beautiful, stylish, no expansion in the sun, no shrink in the winter cold, no metal to strengthen, anti-aging, with the building with the life (about 50 years).
Glass fiber reinforced glass fiber reinforced material, is the early 20th century, the development of a new composite materials, it has a light, high strength, corrosion, insulation, insulation, noise and many other advantages.
Glass fiber reinforced plastic doors and windows are made of alkali glass fiber roving and its fabric as a reinforcing material, the use of unsaturated resin as a matrix material, through a special process to these two materials composite, and add other mineral filler, and then heat curing, All kinds of different sections of the fasting profile processing.
Fiberglass doors and windows of the main features are:
Anti-aging, high strength. Fiberglass profiles of the fasting abdominal cavity without steel as a lining, do not need any single material to enhance the auxiliary, relying entirely on its own structure support. As the glass fiber and its fabric as a reinforcing material, after the resin bonded without wool exposed, the mechanical pultrusion heat curing molding, so bending, bending, anti-deformation.
Corrosion resistance, long life FRP is a high quality composite material. It is acid, alkali, salt, oil and other corrosive media have a special anti-corrosion function, will not rust. Ordinary PVC life of 15 years, and glass fiber life of 50 years, and the basic life of the building, so the use of glass fiber reinforced plastic doors and windows can reduce the trouble of replacing windows and doors, save money.
FRP doors and windows with the following excellent features:
(A) light high strength
FRP profile density of 1.7 or so, it is 4 to 5 times lighter than steel, and the strength is very large, the tensile strength of 350 ~ 450MPa, and ordinary carbon steel close to the bending strength of 388MPa, bending elastic modulus of 20900MPa, Reinforced with steel lined, "Beijing Shengfeng Sunshine" brand glass steel windows by the detection, wind pressure performance of 5.3Kpa, more than the international standard GB / T7106-2002 level 8.
(B) energy-saving insulation
FRP section thermal conductivity of 0.39W / m · k, only the metal 1/100 ~ 1/1000, is an excellent thermal insulation material. In addition, fiberglass profiles for the fasting structure, and all the gaps are rubber strips, tops sealed, so the insulation effect is significant. (GB / T8484-2002 standard 8 level; FRP flat window (single frame three glass), glass fiber reinforced plastic window window (single frame double glass window) heat transfer coefficient K0 = 2.2W / (m2K) Window) heat transfer coefficient K0 = 1.8W / (m2 · K), is GB GB / T8484-2002 standard 9 level; glass fiber flat window (single frame three glass windows, low radiation glass) heat transfer coefficient K0 = 1.3 W / (m2 · K), is GB GB / T8484-2002 standard 10 level.
(C) good sealing performance
Glass fiber reinforced plastic doors and windows in the assembly process, the corner of the use of adhesive plus screw process, while all the gaps are used rubber strips and tops, coupled with a special profile structure, so good sealing performance. By the National Building Engineering Quality Supervision and Inspection Center, Beijing Building Hardware Plumbing Product Quality Supervision and Inspection Station, Beijing Construction Engineering Quality Inspection Center were detected, including air tightness GB / T7107-2002 standard to meet the five levels; watertight performance GB GB / T7107-2002 standard level 3.
(D) health, green, energy-saving effect is remarkable
Glass fiber reinforced plastic doors and windows profiles by the test results in line with GB6566-2001 "building materials radionuclide limit" in the main requirements of the main building materials, test results 0.2, the internal exposure index 0.2, external exposure index 0.2.
(5) sound insulation effect is good
By the National Construction Quality Supervision and Inspection Center, "Beijing Shengfeng Sunshine" brand glass glass double glass and three glass window air sound volume volume RW were 36 dB and 39dB, sound insulation performance level of 4.
(6) corrosion resistance
FRP is an excellent corrosion-resistant material, the acid, alkali, salt and most of the organic matter, seawater and moisture have a better resistance to the role of micro-organisms have resistance. It is particularly suitable for use in rainy, humid and coastal areas, as well as corrosive media.
(7) good dimensional stability
FRP profile linear expansion coefficient of 7.3 × 10-6 / ℃, lower than steel and aluminum alloy , is plastic 1/15. Therefore, glass and steel doors and windows size and stability, temperature changes will not affect the normal switching function of doors and windows.
(Eight) good weather resistance
FRP is thermosetting plastic, resin cross-linking after the formation of three-dimensional network of molecular structure, into insoluble non-melt, even if the heat will not melt. FRP profile heat distortion temperature above 200 ℃, high temperature performance. And better resistance to low temperature performance.
(9) good insulation performance
FRP is a good insulating material, it is not affected by electromagnetic waves, does not reflect the radio waves, through microwave, and can withstand high voltage without damage. As a result, FRP doors and windows have special uses for buildings of temporary buildings and communication systems.
(Ten) shock absorption performance
FRP section elastic modulus of 20900, made with its doors and windows have a high shock absorption frequency, FRP resin and fiber interface with a shock-absorbing and seismic capacity, to avoid the structural parts of the resonance in the working state caused by the early damage.
(Eleven) rich colors
Fiberglass profiles high hardness, can paint a variety of coatings, made of various colors of the doors and windows to adapt to different styles and grades of the building facade effect.
