The reason why the broken bridge aluminum doors and windows are called broken bridges is that they are disconnected by the black insulation strip in the middle. If there is no insulation strip, then the broken bridge aluminum doors and windows are also ordinary aluminum alloy doors and windows, so It is conceivable how much the thermal insulation strip plays in the broken bridge aluminum doors and windows, so the thermal insulation strip has become the heart of the broken bridge aluminum profile. What kind of material is the insulation strip? Baotai insulation strip editor will introduce to you.
The thermal insulation strip is an important structural part of the strip-type thermal insulation aluminum profile, and it is the only external structure that connects the inner and outer cavity aluminum alloy profiles. Therefore, the thermal insulation strip is not only a functional part, but also a structural part. Therefore, do not use inferior thermal insulation strips. The quality of the thermal insulation strips will seriously affect the safety of the entire window. If the quality of the thermal insulation strips cannot be guaranteed, the investment in other materials will be meaningless.
The special material for heat insulation strip has good anti-aging, anti-ultraviolet performance, long service life and superior chemical corrosion resistance. The thermal expansion coefficient is close to that of the aluminum profile, which ensures that the thermal insulation strip and the aluminum profile are closely combined in the case of a large temperature difference. The heat distortion temperature is high, which can meet the follow-up treatment of the profile surface.
