Aluminum Windows VS PVC Windows: Which Is Better for Your Home?

In daily life, when we choose building windows, common products on the market are aluminum alloy windows and PVC windows.

Aluminum alloy has excellent corrosion resistance and oxidation resistance. After anodizing or powder spraying, it can not only improve the corrosion resistance of aluminum profiles, but also prevent deformation. They are not easy to rust and have a service life of 20-30 years longer than plastic windows. Although PVC windows have stable performance under normal conditions, they have poor resistance to high temperatures and mechanical shocks. Long-term exposure to humid environments will cause them to age, fade or crack, shortening their service life.

Thermal insulation performance will directly affect the indoor thermal insulation effect and energy consumption. The window frame of PVC windows is made of PVC material. Relying on the low thermal conductivity of PVC material, its heat resistance is even more than a thousand times that of aluminum. On the contrary, aluminum windows are prone to form a "thermal bridge effect", which leads to rapid heat conduction and affects thermal insulation performance. However, with the advancement of technology, through multi-cavity design and thermal insulation strips, high-end thermal insulation aluminum windows use multi-cavity structure + EPDM strip sealing, and the thermal insulation performance is close to or even exceeds that of plastic steel windows.

PVC window frames are made of plastic, which has low thermal conductivity and excellent performance. Aluminum alloy windows are usually more expensive than PVC windows. PVC windows are cheaper, but the rigidity of plastic materials is poor, and steel bars need to be added inside to increase hardness. The frames of aluminum alloy windows are made of extruded aluminum alloy, and in order to insulate, they need to go through various design processing, which leads to their high prices. Aluminum windows are expensive, but they are much more durable than PVC windows and have relatively low maintenance costs. We should choose the windows that best suit our homes according to our needs and economic strength.
