Performance analysis of plastic steel doors and windows

1. Strong processability. In the molten state, plastic has relatively high fluidity, so a precise cross-sectional structure can be formed through the mold, and divided cavities can be formed to improve the thermal insulation, sound insulation, and drainage functions of the window, and to avoid the use of reinforced steel. rust.

2. Energy saving. Plastic doors and windows have superior technical characteristics than other doors and windows in terms of energy saving and improving indoor thermal environment. According to tests by the Institute of Physics of the Institute of Construction, the heat transfer coefficient of single glass steel and aluminum windows is 64W/M2K; the heat transfer coefficient of single glass plastic steel windows is about 47W/M2K; the heat transfer coefficient of ordinary double-glazed steel and aluminum windows It is about 3.7W/M2K; while the heat transfer coefficient of double-glass plastic steel windows is about 2.5W/M2K. Doors and windows account for 30% of the building's outer envelope area and dissipate 49% of the heat. It can be seen that plastic steel windows have very good energy-saving benefits.

3. Good sound insulation. The sound insulation performance of steel and aluminum windows is about 19 decibels, and the sound insulation performance of plastic steel windows can reach more than 30 decibels. In an increasingly noisy urban environment, the use of plastic steel windows can make the indoor environment more comfortable.

4. Good appearance. It can adapt to domestic decorative effect requirements, and the human body feels more comfortable than metal. Due to the above outstanding advantages, plastic steel doors and windows are being widely used in our country and have become a new trend in the construction field.
