Q-Lon Weatherseal Gasket

Weatherseal performance matters in windows, that's why all of our PVC products are supplied with Q-Lon pre-inserted into all sections. Q-Lon – known as the “rolled in gasket”, has excellent compression recovery of 99% and a lifetime guarantee. Made with a unique combination of materials and with technical performance unparalleled by any other material used in weatherseals, the Q-Lon gasket offers the highest standard of sealing function – even under extreme conditions. Continuous research and development, as well as strict material inspection and quality inspections, have made Q-Lon one of the best established sealing systems in the industry today.

Specifically designed to meet the different demands of PVC windows, Schlegel’s Q-Lon foam weatherseal maintains consistently high standards of energy efficiency, often exceeding any long-term window performance guarantees.
