FRP doors and windows are the fifth generation doors and windows products by default in the world. They not only have the firmness of aluminum alloy, but also have the thermal insulation and corrosion resistance of plastic steel doors and windows. The advantages of FRP doors and windows are light weight and high strength; The second is good sealing performance, energy saving and heat preservation. The biggest disadvantage of FRP doors and windows is that they are hard and brittle, and it is difficult to repair the damage caused by collision during installation. FRP doors and windows also have different deviations according to different prices of quality and function.
We often see all kinds of doors and windows in our life, from tempered glass doors and windows commonly used in commercial buildings to aluminium windows for residential use. Let's learn about FRP doors and windows.
1. How about FRP doors and windows
what are FRP doors and windows:
FRP doors and windows are the fifth generation doors and windows products by default in the world. They not only have the firmness of aluminum alloy, but also have 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 glass fiber reinforced plastic doors and windows, it can produce expansion effect, while in cold winter, FRP doors and windows will not shrink, but also strengthen their own functions, which is very anti-aging. Most FRP doors and windows have the same length of life as buildings. Due to their unique materials and structures, they have certain excellent characteristics and are widely loved by consumers.
Excellent features of FRP doors and windows:
one of the most important features of FRP doors and windows is light weight and high strength. Its density is very small, but its strength is very large. The tensile strength can even be comparable to that of carbon steel. Even if the domestic FRP has been tested, the wind pressure resistance can reach 5.3kpa, which is far ahead in international standards. Secondly, we have to notice that glass fiber reinforced plastic doors and windows are still typical representatives of energy saving and heat preservation. Its thermal conductivity is only 1% to 1‰ of metal, so it is an excellent thermal insulation material. As a representative of the empty structure, FRP doors and windows are sealed with adhesive strips and wool tops, and the heat insulation effect is amazing.
FRP doors and windows price:
FRP doors and windows also have different deviations according to different prices of quality and function. Generally speaking, domestic double-layer tempered glass soundproof FRP doors and windows are more expensive, even domestic mozi and other brands, the price is about 1700 yuan. Second, for the FRP doors and windows dedicated to the sun room of the villa, the price is relatively favorable. Generally, a suitable FRP window can be purchased under 500 yuan, this is due to the narrow area of the Sunshine Room. In addition, the price of glass doors and windows is generally below 1000 yuan, and this moderate price also meets the actual needs of many people.
II. Objective evaluation of FRP doors and windows
advantages of FRP doors and windows:
one is light weight and high strength.
Fiberglass section is empty and the relative density is 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 manufacturing costs.
The second is good sealing performance, energy saving and heat preservation.
During the assembly process of FRP doors and windows, all gaps are sealed by rubber strip and wool tops, so the sealing performance is good. At the same time, the thermal conductivity of fiberglass section is low, only 1/1000~1/100 of metal, and its special hollow profile structure has good thermal insulation.
Disadvantages of FRP doors and windows
first of all, the production process of FRP door & window profile is not perfect, the production efficiency is low, the rejection rate is high, and the technical workers in the industry are scarce. The produced profiles need a lot of repair work before they are used to group Windows, which also brings hidden dangers to doors and windows.
Secondly, glass fiber reinforced plastic doors and windows are not mature, the process of group Windows is complicated, the production efficiency is low, and skilled technicians are needed to do the windows well;
third, glass fiber reinforced plastic doors and windows are not easy to protect during installation. The biggest disadvantage of glass fiber reinforced plastic doors and windows is that they are hard and brittle. If the installation is caused by collision, it is difficult to repair them.
Fourth, each manufacturer regards FRP doors and windows as a gimmick. Under the condition of imperfect production technology, they sell the technology to other manufacturers. The other party applies this imperfect technology to production, there are many problems in the doors and windows made, causing customers to have a bad impression on FRP doors and windows.
