1. The difference in grade:

Aluminum alloy thermal windows and UPVC windows are suitable for different building consumer groups. Statistics show that UPVC windows are suitable for general low-rise residential buildings. Consumers of this grade of products are often concerned about the product. The quality requirements are not very high, and high-performance thermal insulation aluminum alloy windows are suitable for buildings of various heights and grades, and the quality and life performance can withstand the test of high standards.

2. The difference in performance:

The energy-saving effects of the two are similar; but due to the difference in material, UPVC windows are prone to deformation after a period of use, and the sealing performance is not as good as high-performance aluminum alloy windows.

3. Difference in service life:

Due to the large difference in material strength, elastic modulus and wear resistance, the service life of high-performance aluminum alloy windows is often longer than that of UPVC window.

4. The price difference:

Generally speaking, the price of high-performance aluminum alloy windows is usually higher than that of UPVC window. However, in the long run, although the price of high-performance aluminum alloy windows is high, they have a long service life; while UPVC window are cheaper but have a short service life. Therefore, the overall price ratio is comparable.

In summary, high-performance aluminum alloy windows have more competitive advantages.
