FRP doors and windows are the default fifth generation doors and windows products in the world. It not only has the firmness of aluminum alloy, but also has the thermal insulation and corrosion resistance of plastic steel doors and windows. In addition to these two characteristics, it also has the characteristics of colorful, beautiful and fashionable. When the sun shines on FRP doors and windows, it can have expansion effect, while FRP doors and windows will not shrink in cold winter, It will also strengthen its own functions. Let's learn about the ten advantages of FRP doors and windows!

1. Light weight and high strength

The FRP wondow and door profile is hollow, with a relative density of about 1.8. Its tensile strength is close to that of ordinary carbon steel, and its bending strength and bending elasticity are also very good. Therefore, it does not need to be reinforced with steel lining, which also saves the manufacturing cost.

2. Good sealing performance, energy saving and thermal insulation

During the assembly of FRP doors and windows, all gaps are sealed with rubber strips and wool strips, so the sealing performance is good. At the same time, the thermal conductivity of FRP profile is low, only 1 / 1000 ~ 1 / 100 of metal. In addition, its special hollow profile structure has good thermal insulation.

3. Corrosion resistance and aging resistance

FRP doors and windows have good resistance to inorganic acid, alkali, salt, most organic matter, seawater and humid environment, and also have resistance to microorganisms. Therefore, in addition to being suitable for dry areas, they are also suitable for rainy and humid areas, coastal areas and chemical sites. Although aluminum alloy doors and windows have good atmospheric corrosion resistance, they are powerless to the electrochemical corrosion of some metals. PVC plastic steel doors and windows are resistant to moisture, salt fog and acid rain, but under the action of ultraviolet light, its macromolecular chain will break, resulting in the loss of luster, discoloration and pulverization of the material surface and the decline of mechanical properties. Under normal service conditions, the service life of FRP doors and windows can reach 30 ~ 50 years, the average service life of aluminum alloy doors and windows is 20 years, and the average service life of PVC plastic steel doors and windows is around 15 years.

4. Good weather resistance

FRP is a thermosetting plastic. After resin crosslinking, it forms a three-dimensional network molecular structure and becomes insoluble and melt. It will not melt even when heated. The thermal deformation temperature of FRP profile is above 200 ℃, with good high temperature resistance. The low temperature resistance is better.

5. Good insulation

FRP is a good insulating material. It is not affected by electromagnetic wave, does not reflect radio wave, has good microwave permeability, and can withstand high voltage without damage. Therefore, FRP doors and windows have special uses for field temporary buildings and buildings with communication system.

6. Good shock absorption performance

The elastic modulus of FRP profile is 20900. The doors and windows made of it have high damping frequency. The combination of resin and fiber interface in FRP has the ability of shock absorption and earthquake resistance, and avoids the early damage caused by resonance of structural members in the working state.

7. Rich color

FRP profiles have high hardness and can be coated with various coatings to make doors and windows of various colors, so as to adapt to the facade effects of buildings of different styles and grades.

8. Good sound insulation effect

According to the inspection of the national construction engineering quality supervision and inspection center, the weighted sound insulation RW of "WAYTONG" brand FRP double glass and three glass window air acoustic meter reaches 36 dB and 39 DB respectively, and the sound insulation performance grade is grade 4.

9. Corrosion resistance

FRP is an excellent corrosion-resistant material. It has good resistance to acid, alkali, salt and most organic matter, seawater and humidity, and also has resistance to the action of microorganisms. This characteristic is especially suitable for use in rainy, humid and coastal areas, as well as places with corrosive media.

10. Good dimensional stability

The linear expansion coefficient of FRP profile is 7.3 × 10-6 / ℃, lower than steel and aluminum alloy [1], 1 / 15 of plastic. Therefore, the dimensional stability of FRP doors and windows is good, and the change of temperature will not affect the normal switching function of doors and windows.
