First of all, what are uPVC windows & doors?

uPVC windows&doors are made of polyvinyl chloride (UPVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc. way to make door and window frame fan.

Aluminum alloy doors and windows are doors and windows made of aluminum alloys. When many people choose doors and windows, they do not know whether to use uPVC windows&doors? Or aluminum alloy doors and windows? If you don't know the difference between the two, then this article will tell you the difference between the two.

The first is strength and weight: the strength of aluminum alloy is three times that of uPVC Profiles, and the wind resistance is two levels higher than that of plastic steel. The aluminum alloy window frame of the same volume is only one third of the weight of the plastic steel window.

The second point is weather resistance and corrosion resistance: aluminum alloy has good weather resistance and plastic steel, which can be maintained for more than 10 years without discoloration, and its comprehensive corrosion resistance is also better than that of plastic steel.

The third point is deformation: the linear expansion coefficient of uPVC Profiles is 3 times that of aluminum alloys, so its thermal expansion and contraction deformation are large.

The fourth point is safety and environmental protection: aluminum alloy has high temperature resistance, good non-combustibility, is a good conductor, can prevent lightning and anti-static, can be recycled, and is beneficial to environmental protection. Static electricity, slow degradation, unfavorable recycling, slow combustion will release toxic gas, which has an impact on environmental protection.

The fifth point is decoration: aluminum alloy is rich in color and strong in decoration, which can meet the individual needs of different quality real estate and commercial buildings. Aluminum alloy has high strength, good rigidity, light weight, good fire resistance, weather resistance, Corrosion resistance, environmental protection, good thermal insulation effect, high cost performance.

The above 5 points are the difference between aluminum alloy doors and windows and uPVC windows&doors. Seeing this, I believe you have a general understanding of the two.
