1. Grade Shang of difference: domestic of aluminum broken hot window and steel window is respectively for Yu different building of consumption groups, statistics information displayed, steel window applies Yu General lower residential, often this grade of products of consumers on the products of quality requirements not is high, and high performance broken hot aluminum window is applies Yu various height, and various grade building, and quality, and life performance are suffered have live high standards test.
2. The difference in performance: energy saving effect of the two similar but due to material differences, plastic Windows use after a period of time are susceptible to deformation, sealing properties than high performance aluminum Windows.
3. The difference in life expectancy: due to the material's strength and modulus and abrasion resistance vary greatly, makes high-performance aluminum window service life than the life of plastic Windows.
4. The difference in price: by and large, high performance aluminum window price is usually higher than the price of plastic Windows. But long term, high performance aluminum window price is high, but long life; and plastic-steel Windows, although prices are cheaper, but life is short. Therefore, for the price.
