Fortress Windows & Doors Ltd began in the 1960’s when Neil Manning of North Battleford opened the doors of a new company called Alumi Glass, specializing the manufacture of aluminum sliding windows.  These “new-style” windows addressed the issues of re-painting and repairing rot in old wood windows.

But aluminum windows had a downside:  they were cold.  The metal frames attracted frost and were not well-suited for winters on the Canadian Prairies.  Enter the PVC window.  PVC (polyvinyl chloride), one of the most widely used plastics in the world, proved to be ideal for windows: strong, warm, maintenance-free, durable, and affordable.  In 1985, Alumi Glass became North Battleford’s first, ON manufacturer of the revolutionary window product.

No maintenance! Frames are prefinished with Ektacron vinyl wrap which eliminates painting. The steel insulated door panels have a white Polytex coating (not primer) which needs no further paint.

  • Superior strength frames.
  • High R-value polyurethane foam insulation.
  • An enormous selection of panels and glass inserts for a look that suits your home.
