Extremely well. Derchi’s thermal‑break aluminum frames prevent heat loss in winter, reduce heat gain in summer, and resist warping during freeze–thaw cycles. Paired with triple glazing, they deliver excellent insulation, low air leakage, strong wind resistance, and reliable year‑round durability — ideal for Ontario’s −25°C cold snaps, humidity swings, and high‑wind storms.

A robust manufacturer warranty: 10 years on the aluminum frame, 5 years on hardware, and 2 years on glass. Crucially, we act as the local face of that warranty. Client deal directly with us.

Every order is 100% custom-manufactured to exact architectural specifications and shipped directly to the project. This lean model eliminates local warehousing bloat, allowing us to pass massive savings onto the buyer.

Approximately 12 to 16 weeks. While this is an import timeline, it is highly competitive with custom domestic orders from legacy brands, making it perfectly aligned with standard new-build construction schedules.

To optimize shipping economics and deliver our disruptive price point, our minimum order value is $30,000. This naturally qualifies our ideal pipeline: full custom home builds and major architectural additions. 

We’re happy to share references from homeowners, contractors, and builders who’ve worked with us firsthand. If you’d like to see the quality up close, you’re always welcome to walk through one of our recent projects and get a feel for the fit, finish, and performance of our aluminum windows in a real home.

Our core lineup is fully CSA-certified, including casements, fixed, and tilt-and-turn windows. Our windows carry Energy Star certification, proving their efficiency in the Canadian climate.
