Broken bridge aluminum doors and windows it is the third generation of building doors and windows following aluminum alloy doors and windows and plastic steel doors and windows, because it has many irreplaceable advantages of common doors and windows and is favored by the majority of owners. Because it meets the development needs of energy conservation and environmental protection in the Times, it has won the favor of the vast number of engineers. In the end broken bridge aluminum doors and windows what are the advantages: We also asked insiders, he said: "Bridge-cutoff aluminum alloy doors and windows is the most advanced door and window at present, following aluminum clad wood, stainless steel, plastic steel, and the fifth generation of new heat insulation energy-saving doors and windows after ordinary color aluminum alloy doors and windows, broken bridge aluminum doors and windows it has the following advantages:
1, broken bridge aluminum doors and windows good heat preservation and insulation: the inner and outer frames of the heat insulation profile are combined with softness. The Frame adopts a rubber strip and a double wool tops three-seal form. It is tightly closed, with excellent air tightness, excellent water tightness and excellent heat preservation performance; casement the hollow glass structure is adopted to make the windows really show sound insulation, heat insulation, heat preservation and excellent functions, greatly saving the cost of mining and refrigeration, and the heat transfer coefficient K value has been tested 2.23? Below 2.94w/2K, the energy saving effect is remarkable, and the energy saving cost of several years is enough to make up for the previous investment.
2, broken bridge aluminum doors and windows waterproof function: use the principle of pressure balance to design a structural drainage system, slide down design Bevel ladder type, set drainage outlet, smooth drainage, good water tightness.
3, broken bridge aluminum doors and windows noise protection sound insulation: The structure is carefully designed, the joints are tight, and the test results show that the air sound insulation reaches 30-40db, which can ensure that residents within 50 meters on both sides of the expressway are not disturbed by noise, adjacent to the downtown can also ensure the quiet and warm interior.
4, broken bridge aluminum doors and windows anti-condensation and Frost: The Broken Bridge aluminum profile can realize the three-way sealing structure of doors and windows, reasonably separate the water vapor chamber, successfully realize the equal pressure balance of air and water, and significantly improve the water tightness and air tightness of doors and windows, achieve the effect of clear and bright windows.
5, broken bridge aluminum doors and windows anti-theft and anti-loosening devices: equipped with unique multi-point hardware locks to ensure the stability and safety of windows in use.
6. Broken Bridge aluminum high strength unchanged type, maintenance-free: broken bridge aluminum doors and windows the tensile strength, shear strength and thermal deformation resistance of the body are high, strong and durable. The Broken Bridge aluminum profile is not easy to be eroded by acid and alkali, is not easy to turn yellow and fade, and almost does not need maintenance. Broken bridge aluminum doors and windows it is being adopted by more and more high-grade buildings and becomes a real green energy-saving door and window.
