At present, wooden windows and steel windows have gradually withdrawn from the historical stage, and plastic steel windows and aluminum alloy windows have begun to play a major role. So, which is better for plastic-steel windows and aluminum alloy windows? How to buy home windows? The following small series will introduce the advantages and disadvantages of plastic-steel windows and aluminum alloy windows in detail, to help you decide which plastic window and aluminum alloy window is good.
First, the difference between plastic steel window and aluminum alloy window
Plastic window
Advantages: not only beautiful and durable, but also the lowest thermal conductivity. It is far superior to wood windows, iron windows and aluminum alloy windows in terms of energy saving, and is the most effective sealing method. Ordinary plastic steel is moderately priced and economical. The high-grade plastic steel window has good heat preservation and is resistant to aging and is not easily deformed.
Disadvantages: Sealing, safety, anti-theft and ventilation quality are not satisfactory. The reason is that the plastic steel material lacks the high-quality hardware used in the matching, which causes the current high-grade profile to match the disharmonious state of the low-grade hardware, and the plastic (PVC) can not be degraded, and the discarded plastic steel window is difficult to handle, which is unfavorable to environmental protection. There are gaps that are easy to rust, sound insulation is slightly poor, ordinary plastic steel windows are easy to deform, high-grade such as imported is expensive, thousands of yuan per square meter.
2. Aluminum alloy window
Advantages: corrosion resistance, strong fire resistance, long service life (50-100 years), can be recycled and reused after scrapping, without any pollution. colorful. The inner and outer surfaces of aluminum can be of different colors and different patterns. High-grade broken bridge aluminum alloy can not only be insulated, but also cold. Light weight, high strength, long service life, good fire resistance and good lighting performance.
Disadvantages: the use of precious metal materials, high thermal conductivity, poor thermal insulation, thermal insulation performance, energy loss. Insulation is one of the basic requirements for material selection of windows.
Second, plastic steel window and aluminum alloy window contrast
PK Project 1: Which price is more affordable?
Result: Plastic steel windows are suitable for working class
From the price point of view, the plastic steel doors and windows are generally between 200 yuan and 300 yuan (per square meter), the double layer is more than 500 yuan, the aluminum alloy doors and windows are basically above 190 yuan, and the good quality is at four or five hundred yuan. Thousands of dollars. Due to different materials, the prices of the two are of course different. The price of plastic steel doors and windows is more affordable for the working class, while the aluminum alloy doors and windows are installed at home, and the price is better for middle- and high-income families.
PK Project 2: Which is better for insulation?
Result: Plastic steel doors and windows win
Referring to the thermal insulation performance, the aluminum alloy window is compared with the technical parameters of the material base. The main component of the plastic steel door and window except the steel core is PVC material. Under the same conditions, in terms of the heat resistance of the material, the PVC material is thousands of times more than the aluminum material. . As long as the steel doors and windows are regular products that meet the national standards, they will surely achieve the desired insulation effect.
The aluminum alloy is relatively poor, but in recent years there has been a broken bridge aluminum technology. The broken bridge color aluminum alloy doors and windows are made up of two different sections through energy-saving insulation strips. Its main function is to break the heat transfer channel and prevent it. Cold and heat conduction is rapid.
PK Project 3: Which is better for sound insulation?
Result: Plastic steel doors and windows win
The sound insulation effect of plastic-steel windows is relatively better than that of aluminum alloy windows. To achieve the same noise reduction requirements, the distance between the building with aluminum windows and the main road must be 40 to 50 meters, and the installation of plastic steel windows can reach about 20 meters.
Aluminum alloy doors and windows have also been innovated in recent years, and its sound insulation effect is also constantly improving, but relatively speaking, plastic steel windows are better.
PK Project 4: Which kind of wind pressure is safer?
The result: aluminum alloy doors and windows won
For high-rise tenants, wind resistance is a problem that must be considered when purchasing windows, because the higher the floor, the greater the wind. The elasticity and tensile strength of plastic steel are not as good as aluminum alloy, but the quality of steel doors and windows should be no problem. However, if the quality of plastic steel doors and windows is not good, the internal steel lining and hardware are not too hard, it will cause trouble to consumers. Therefore, it is recommended that high-rise households should use regular aluminum alloy doors and windows.
These two materials can be said to have their own characteristics in the market. Plastic steel profiles have won the favor of consumers because of their environmental protection, energy saving and corrosion resistance. Aluminum alloy profiles have always been good in stability and unique metal texture. Deeply sought after by users, which one is better, the key is to look at personal preferences. But no matter which product you choose, you must buy it from a regular manufacturer.
