Aluminum alloy doors and windows have been sought after by consumers in recent years, and plastic steel doors and windows in the past has also been a leader in the field of doors and windows. Who will be the winner in this competition? Let's take you to have a look.
1. From the perspective of thermal insulation performance, thermal insulation performance is a very important standard for doors and windows, and the most direct role of doors and windows is to shelter the house from the wind and rain. In terms of this performance, the thermal insulation of aluminum alloy doors and windows is slightly longer than that of plastic steel materials.
2. From the perspective of fire resistance, the fire resistance of flame-retardant PVC plastic doors and windows is better than that of combustible wood doors and windows, but it is poor compared with non combustible aluminum alloy doors and windows. In addition, plastic doors and windows will emit toxic gases when burning, so some European countries stipulate that public buildings should not use PVC doors and windows. Compared with this, the melting point of aluminum alloy is very high, even if it reaches the melting point, the combustion will not release toxic gas, and the thermal conductivity of doors and windows is very slow in case of fire.
3. The appearance of the beautiful is also a very competitive measure, very decorative color is very important to the effect of architectural art, plastic steel doors and windows as building windows, can only be white. The heat resistance and weather resistance of colored PVC profiles are greatly reduced, so they can only be used indoors. Relatively speaking, aluminum alloy doors and windows have a wide range of surface colors, including white, green and other colors, wood grain, granite and other surface colors. Even the most common color is close to the color of silver jewelry, which looks very beautiful and atmospheric.
4. Of course, if you look at the price, the cost performance of aluminum alloy doors and windows is higher than that of plastic steel doors and windows. Although the price of aluminum alloy doors and windows is 1.5 times of that of plastic steel doors and windows, that is, the price of plastic steel doors and windows is 33% cheaper than that of aluminum doors and windows. However, the comprehensive properties of aluminum alloy doors and windows, such as high strength, high performance, excellent corrosion resistance (spray paint), decorative effect and long service life, are far better than those of plastic steel doors and windows.
