PVC windows:

1) adiabatic insulation: PVC plastic thermal conductivity of aluminum alloy is only 11,250, the 1400 steel. Plastic doors and windows of energy loss of housing (whether heating or refrigeration and air-conditioning), only steel window 26% of the energy dissipation, aluminum alloy windows 30% of the energy dissipation. 
2) noise: The use of extruded plastic doors and windows, double glass vacuum insulation effect is greater than 30 dB. 
3) anti-aging: In temperatures of minus 30 to 70 between zero, PVC windows and doors can withstand wind, rain, sun, dry and moist, its color, luster long as new. 
4) the erosion-resistant: PVC doors and windows with wood and aluminum higher than that of the compressive, tensile, anti-hit, crack, anti-expansion of the intensity and is superior to steel, wood and aluminum corrosion resistance, from the air , salt erosion. 
5) Closed: The multi-sealing plastic steel door and window design, and PVC-based smooth surface, not easy to adhesion of dust dirt, dust excellent effect. 
6) elegant appearance: PVC can match a variety of colors such as white, brown, blue, red, yellow, etc., consumers can select, and a large box, wide glass frame structure, it will help indoor lighting. If accompanied by decorative metal accessories, can not only beautify the indoor environment.
