Notes

Installation can be completed with eas by dipping profiles in silicone oil or saponification liquid.
Gasket should not be pulled and stretched during installation. The length of the strip must be about 1% longer than the profiles to avoid seal failure caused by strip shrinkage.
The gasket for the corner of windows and doors should be cut at 45°angles, and the edge should be kept well connected to prevent cracking when shrinkage occurs.
If there is breakage of the strip, don't set it at the corner. It is better to set it in a longitudinal direction during installation as it butts up to the breakages well and bonds more effectively.
