Characteristics, advantages and disadvantages of FRP windows

Glass fiber reinforced plastic window is a new type of door and window. The design of FRP windows is beautiful and fashionable, which is loved by more and more owners. But many people still don't know much about FRP windows. What are its characteristics, advantages and disadvantages? Today, Bian Xiao will answer your questions one by one.

Light weight and high strength

The density of FRP profile is about 1.7, which is 4 ~ 5 times lighter than steel, but it is very strong. Its tensile strength is 350 ~ 450 MPa, which is close to that of ordinary carbon steel. Its flexural strength is 388MPa and its flexural elastic modulus is 20900MPa, so it is unnecessary to use steel lining for reinforcement.

Energy saving and heat preservation

The thermal conductivity of FRP profile is 0.39W/mk, which is only1100 ~11000 of metal. It is an excellent thermal insulation material. In addition, the glass fiber reinforced plastic profiles are hollow structures, and all gaps are sealed with rubber strip and the top, so the heat insulation effect is remarkable.

Good sealing performance

In the assembly process of FRP doors and windows, the corners are glued and screwed, and all gaps are sealed with rubber strips and tops. The special profile structure makes the sealing performance good.

Corrosion resistance and aging resistance

Glass fiber reinforced plastic (FRP) is an excellent corrosion-resistant material, which has good resistance to acid, alkali, salt and most organic substances, seawater and humidity, and is also resistant to the action of microorganisms. This feature is especially suitable for rainy, humid and coastal areas, as well as places with corrosive media.

The price is slightly more expensive.

Glass fiber reinforced plastic window is not easy to protect during installation. The biggest disadvantage of FRP window is that it is hard and brittle, and it is difficult to repair it if it is damaged by collision during installation. The assembly technology of FRP window is immature, the production cost is high and the price is slightly expensive.
