The most outstanding advantage of thermal insulation bridge broken aluminum alloy doors and windows is good thermal insulation. It is a new type of energy-saving profile developed on the basis of traditional aluminum alloy profiles under the premise of energy conservation and environmental protection. It is also the preferred product of high-grade building doors and windows. The aluminum alloy profile is divided into two parts by nylon heat insulation strip. Block the heat conduction of aluminum profile. Similarly, the quality of reinforced nylon spacer directly affects the service life of bridge broken aluminum alloy window.
Heat insulation broken bridge aluminum alloy doors and windows to see which aspect can know the quality is not good
1、 Materials: the quality of aluminum profiles is mainly reflected in the thickness, strength and oxide film of aluminum profiles. There are also relevant national standards for aluminum profiles. For example: the wall thickness is more than 1.2mm, and the tensile strength per square millimeter is not less than 157 Newton. The thickness of the oxide film should not be less than 10 microns to 108 Newtons per square millimeter. If not up to the above standards, it is poor quality aluminum alloy doors and windows, can not be used.
2、 See processing: high quality aluminum alloy doors and windows, fine processing, detail processing in place, good integrity, stable structure, good operability. However, poor quality aluminum alloy doors and windows are poorly manufactured. They are not installed in accordance with the requirements due to poor sealing performance and improper opening and closing. In addition, they not only leak air and rain, but also have strong wind and external force, which makes it easy to blow off or bump the push-pull parts or glass, and damage and hurt people.
3、 Look at the price: in general, high-quality aluminum alloy doors and windows, due to high production costs, the price is about 30% higher than that of inferior aluminum alloy doors and windows. Some aluminum alloy doors and windows with wall thickness of only 0.6-0.8 mm aluminum profiles have tensile strength and yield strength much lower than the relevant national standards, so they are not safe to use.
In addition, the best choice of regular aluminum alloy doors and windows manufacturers products, whether aluminum profiles or door and window hardware accessories should choose reliable brands. For aluminum alloy doors and windows, the quality of hardware accessories is very important. It also affects the price of windows to a large extent. For example, the quality difference between imported hardware and domestic hardware is very big.
