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.
