Modern Canadian alpine residence with floor-to-ceiling Compel windows opening onto a deck overlooking a mountain lake.

European craft.
Canadian climate.

Premium windows and doors for architects, builders, and homeowners who care how a building closes.

— 01   Philosophy

We work with European ateliers rooted in traditional trades — joiners, glaziers, millworkers — to deliver windows and doors that meet Canadian climate standards without compromising the craftsmanship of the old world. Every specification begins with the architect's intent.

Two systems, one standard.

The Gemini family — each line engineered for a different performance envelope, both finished with the same European craftsmanship.
