Broken Bridge insulated aluminum alloy doors and windows are increasingly favored by the market for their outstanding advantages such as high strength, strong thermal insulation, large lighting area, good corrosion resistance, long service life and good decorative effect, high-quality Broken Bridge aluminum alloy doors and windows have gradually become the first choice for high-end building doors and windows. Because of this, there are more and more doors and windows posing as broken bridge aluminum on the market. Therefore, correctly distinguish
broken bridge aluminum doors and windows and non
broken bridge aluminum doors and windows it seems necessary.
"Bridge" in broken bridge insulation aluminum refers to "cold and hot Bridge" in the sense of material science, while the word "broken" indicates action, that is, "breaking cold and hot Bridge". Because aluminum alloy is a metal, the heat conduction is relatively fast, so when there is a lot of difference between indoor and outdoor temperatures, aluminum alloy can become a "bridge" that transfers heat. Such materials are made into doors and windows, its thermal insulation performance is not good. However, the broken bridge insulation aluminum disconnects the aluminum alloy from the middle. It uses the insulation strip to connect the disconnected aluminum alloy as a whole, so the heat cannot easily pass through the whole material, and the heat insulation performance of the material becomes better, this is the origin of the name "Broken Bridge aluminum.
Broken Bridge insulated aluminum doors and windows have many advantages due to their natural advantages.
1. Good thermal insulation. The combination of heat insulation profile and inner and outer frame is adopted, and the frame is sealed by EPDM strip, which is tightly closed, with excellent air tightness, water tightness and excellent heat preservation performance. The Casement adopts hollow glass structure, the window really shows the functions of sound insulation, heat insulation and heat preservation. The heat transfer coefficient K is generally below 1.8-2.5w/2K, and the energy saving effect is remarkable.
2. Waterproof function. The structural drainage system is designed based on the principle of pressure balance, and a drainage outlet is added to ensure smooth drainage and good water tightness.
3. Noise protection sound insulation. Its structure has been carefully designed, the joints are tight, and the air sound insulation can reach 30-40db, which can ensure that residents within 50 meters on both sides of the expressway are not disturbed by noise, even if it is adjacent to downtown, it can ensure the tranquility and warmth of the room.
4. Against wind and sand. Wind pressure resistance. Inner frame straight material adopts hollow design, strong wind pressure deformation resistance and good off register resistance. It can be used in high-rise buildings and residential buildings, with large lighting area and better air tightness than any aluminum and plastic windows. It can ensure that there is no dust on the indoor windowsill and floor in areas with large wind and sand, and is suitable for designing large-area window types.
5. High strength unchanged type.
Broken bridge aluminum doors and windows the tensile strength, shear strength and thermal deformation resistance of the body are high, and the profile is not easy to be eroded by acid and alkali, not easy to turn yellow and fade, strong and durable.
6. A variety of colors and strong decoration. It can meet the different colors of the interior and exterior surfaces of doors and windows, meet the customer's preference for color effect and the aesthetic needs of color gamut space, and meet the personalized design requirements of architects.
7. Green building materials.
Broken bridge aluminum doors and windows not only does it not produce harmful substances in the production process, but all materials can be recycled and recycled, which is an environmental protection product of green building materials.
8. There are many opening forms, which are comfortable and durable. It has flat type, upper suspension type, push-pull type, etc., and is suitable for public buildings, residential quarters, municipal and other public projects.
