In recent years, the thermal insulation technology of aluminum alloy doors and windows has been very mature, and the thermal insulation performance is also very good, so now the mainstream market is dominated by aluminum alloy.
What is broken bridge insulation?
Before the ordinary doors and windows glass is single-sided, aluminum alloy frame is also integrated molding, metal and glass itself is easy to heat transfer. Now the heat insulation of broken bridge is to add a plastic strip between two aluminum alloy profiles. Because the heat transfer coefficient of plastic is very poor, the heat transfer is cut off, so it is called bridge breaking.
How to identify?
See the specification: the thickness, strength and spraying color of aluminum profiles used for high-quality aluminum alloy doors and windows should be more than 1.2 mm, the tensile strength should be 157 n / m2, the yield strength should be 108 n / m2, and the oxide film thickness should be 10 μ M.
See processing: poor quality aluminum alloy doors and windows, saw cutting instead of milling processing, not installed according to the requirements, poor sealing performance, the switch is not free, not only air and rain leakage and glass burst phenomenon, but also encounter strong wind and external force, easy to pull parts or glass scraping or falling.
Look at hardware: Although hardware is only a small part of the window, its role must not be underestimated. The hardware of high-grade window is made of metal, and its internal strength, appearance and usability directly affect the performance of the window.
