Good thermal insulation performance
The thermal insulation performance of the steel-plastic sliding window is very good, because the thermal conductivity of UPVC, the main material of the steel-plastic sliding window, is very low, and its thermal conductivity is 1/357 of that of steel and 1/250 of that of aluminum. The advantage of low thermal conductivity is that in summer, it is difficult for high-temperature gas to be conducted in, and the heating in the house in winter is not easy to evaporate.
