Gentek’s advanced technology

We prefer Gentek windows because of their advanced all-silicone foam formula, and a unique dual seal design. Gentek fusion-welded corners on PVC vinyl frames provide superior strength and a water- and air-tight seal that no other window can beat. Gentek PVC vinyl windows also meet or exceed the requirements of leading North American industry standards.

Gentek’s lifetime warranty

Gentek offers a lifetime warranty on sealed insulating glass to the original purchaser (please see warranty certificate for details). A leading Canadian manufacturer of home renovation products, Gentek stands behind every window in its North American Windows Collection with one of the best warranties in the industry. The warranty covers:

  • Vinyl frame
  • Sealed glass components
  • All the moving hardware parts
