Thermal expansion and contraction matching of aluminum tooth composite reinforced insulation strip

The aluminum rack of the aluminum tooth composite reinforced insulation strip produced by Shandong Keltai New Material Technology Co., Ltd. makes the expansion coefficient of the insulation strip closer to that of the aluminum alloy profile, and expands and contracts synchronously under temperature difference, avoiding interface debonding, cracking or sealing failure.

Long term weather resistance improvement, reducing performance degradation caused by thermal expansion and contraction, and extending the service life of doors and windows.
