Slim frames. Big views. Built for winter.
Thermally broken aluminum windows with the clean, narrow lines of modern architecture and the insulation Canadian homes need.
The strength of aluminum. Without the cold.
Ordinary aluminum carries cold straight through the frame. A thermobreak window has an insulating barrier built into the middle of the frame, so the outside and inside are separated. You get warm frames, less condensation and the slim, strong profile only aluminum can give.
- No temperature transfer through the frameThe insulating break stops frost and cold spots on the inside.
- Bigger glass, thinner framesAluminum spans large openings without bulky frames or extra dividers.
- Won’t rot or warpPowder-coated aluminum stays straight and true, unlike wood or vinyl.

The right window for every opening.
Mix and match styles in one frame, and add grilles, screens and your choice of hardware.
