What Is Multi-Cavity Broken Bridge Aluminum Doors and Windows


Aluminum alloy multi-cavity seal is an improved version based on the old aluminium windows in order to improve the thermal insulation performance of doors and windows. Through enhanced nylon barrier, aluminum alloy profiles are divided into internal and external parts to block the heat conduction of aluminum. If there are more cavity and wider cross section of the profile, the corresponding thermal insulation performance is also good.

As shown in the following figure, multi-cavity aluminum alloy profiles are extruded to make profiles with the same requirements; Multi-cavity profiles are designed to improve the structure of doors and windows and the performance of heat preservation, heat insulation and sound insulation.

The multi-cavity sealing strip is more flexible and elastic than the ordinary single-layer sealing strip, so the air tightness is higher. Generally, it is a EPDM adhesive strip. You take a plastic steel window, or the adhesive tape on the 300-yuan Pu aluminum window is compared with the high-end door and window rubber strip, and the feel is completely different. This is more understandable depending on the real thing.

On the basis of aluminium windows, the multi-cavity heat insulation profile has been improved and introduced. Generally speaking, it is by adding a layer of heat insulation material from the middle to prevent external heat from being transferred to the inside. It can not only achieve thermal insulation performance, but also have various functions such as waterproof, frost prevention, etc., which greatly improves the thermal insulation performance of doors and windows and reduces building energy consumption.
