Company Profile

Cossins Windows has been family-run in Calgary since 1978. Now in our third generation, we manufacture vinyl, wood, and aluminum-clad windows in our local shop.

We build custom wood and clad window systems with clear hemlock interiors and custom exterior colors. We also carry entry doors, French doors, and skylights.

As a manufacturer-direct supplier, we manage lead times and quality, hosting an active northeast showroom for design consultation and warranty support.
