Now, wooden windows and steel windows have gradually withdrawn from the stage of history, plastic steel windows and aluminum alloy windows began to play the first important role. So, plastic steel window and aluminum alloy window which is good? How to choose home window? The following small series will specifically introduce the advantages and disadvantages of plastic steel window and aluminum alloy window, to help you choose, which is good plastic steel window or aluminum alloy window.
1、 Difference between plastic steel window and aluminum alloy window
1. Plastic steel window
Benefits: not only beautiful and practical, but also the lowest thermal conductivity. In terms of energy saving, it is far better than wood windows, iron windows and aluminum alloy windows, which is the most useful sealing method. The price of general plastic steel is moderate, economical and practical. High grade plastic steel window has good heat preservation, aging resistance and the surface is not easy to deform.
Disadvantages: sealing, safety, security and ventilation quality are not all good. The reason is that the plastic steel materials lack of high-quality hardware, which leads to the disharmony of low-grade hardware of high-grade profiles, and the plastic (PVC) can not be degraded, and the lost plastic steel windows are difficult to deal with, so it is environmentally friendly. There are spaces easy to rust, poor sound insulation, general plastic steel windows easy to deform, high-end, such as imported prices are expensive, thousands of yuan per square meter.
2. Aluminum alloy window
Benefits: corrosion resistance, strong fire resistance, long service life (50-100 years), can be recovered and reused at a high price without any pollution. The color is rich. The inner surface of aluminum can be different colors and stripes. High grade bridge breaking aluminum alloy can not only heat insulation, but also cold insulation. It has the advantages of light material, high strength, long service life, good fire prevention function and daylighting function.
Disadvantages: precious metal materials, high thermal conductivity, poor thermal insulation and heat insulation function, large energy consumption. Thermal insulation is one of the fundamental requirements for the selection of window materials.
