Buy broken bridge aluminum doors and windows because it has sound insulation, heat preservation and sealing effect, so how to choose broken bridge aluminum doors and windows, look at the following points
Selection of window frame
Generally, aluminum alloy is selected as the profile of bridge broken aluminum alloy doors and windows. If the selected profile wall is thin, the sound is easy to penetrate. However, some regular brand bridge breaking aluminum alloy door and window profiles have thicker wall thickness than ordinary aluminum alloy windows, so the sound is not easy to penetrate and the sound insulation effect is better.
Sealing strip selection is most important
High quality sealing strip can play an important role in waterproof, sealing and energy saving, with sound insulation, dust prevention, antifreeze and heat preservation. It must have a strong tensile strength, good elasticity, but also need better temperature resistance and aging resistance. It has been used in engineering to replace rubber strip. It is polyurethane foam sealing strip, commonly known as coated sealing strip. This kind of material not only has the function of aging resistance, but also environmental protection. It is an upgraded high-grade sealant strip. When the door and window sealing strip aging and other problems, it is recommended to replace even.
Selection of glass
At present, the glass used in the market mainly includes insulating glass, laminated glass and vacuum glass. Vacuum glass uses the principle that vacuum can not transmit sound, and can reduce noise by 30-40 dB after installation. The energy transmission of insulating glass is completed by glass and its internal air, and toughened glass has higher safety performance.
Principle of thermal window
Due to the influence of indoor and outdoor temperature difference and humidity, dewing or condensation is easy to occur in winter and summer seasons with large temperature difference, resulting in energy saving loss. In order to solve this energy consumption problem, the broken bridge window will be produced, because the window and glass can be divided into two layers, and the air layer in the middle can play a good role in energy saving.
Sealing around the frame
After installation, the aluminum alloy doors and windows of bridge break must be sealed with glass glue. The sealing around seems simple, but we still need to find a professional master!
