The windows bring light and vitality to the living room, and in the cold winter months, the windows have become the insulation barrier of the living room. Its sealing performance has become an important index for people to choose windows. People used to choose windows and may pay more attention to it. The opening performance, in fact, to understand its insulation performance, window materials, glass, hardware, etc. are essential elements.
The heat-insulated bridge aluminum alloy window is an improved type introduced on the basis of the old aluminum alloy window in order to improve the insulation performance of the door and window. The aluminum alloy profile is divided into inner and outer parts by the reinforced nylon spacer to block the heat conduction of the aluminum. The material and quality of the reinforced nylon spacers directly affect the durability of the insulated aluminum alloy window.
The outstanding advantages of heat-insulated bridge aluminum alloy doors and windows are high strength, good thermal insulation, good rigidity, good fire resistance, large lighting area, good atmospheric corrosion resistance, high comprehensive performance, long service life and good decorative effect. High-grade broken bridge profiles aluminum alloy doors and windows, is the first choice for high-end building windows.
Look at the materials: aluminum profiles used for high-quality aluminum alloy doors and windows, thickness, strength and oxide film, etc., should comply with the relevant national standards, the wall thickness should be above 1.2 mm, the tensile strength reaches 157 Newtons per square meter, yielding The strength should be 108 Newtons per square millimeter and the thickness of the oxide film should be 10 microns. If the above standards are not met, it is inferior aluminum alloy doors and windows, which cannot be used.
Look at processing: high-quality aluminum alloy doors and windows, fine processing, installation, stress, good sealing performance, switch freely. Inferior aluminum alloy doors and windows, blindly selected aluminum profiles and specifications, processing rough and shoddy, sawing instead of milling, not installed according to requirements, poor sealing performance, switch is not free, not only leaking wind and rain and glass burst phenomenon, but also encountered When it comes to strong winds and external forces, it is easy to scrape or knock down the push-pull parts or the glass, causing damage to people.
Look at the price: Under normal circumstances, high-quality aluminum alloy doors and windows due to high production costs, the price is about 30% higher than the inferior aluminum alloy doors and windows. Some aluminum alloy doors and windows made of aluminum profiles with a wall thickness of only 0.6-0.8 mm have a tensile strength and yield strength that are much lower than the national standards and are not safe to use.
In addition, it is best to use the products of regular aluminum alloy doors and windows manufacturers, products that are not processed according to the standard are not easy to reach the standard.
