Steel windows & doors

The versatility of steel allows you to let your imagination run wild: free to create bold architectural designs. Similar to our wood windows, this material allows you to marry your unique taste with our various architectural styles.

Maison Janneau steel windows and doors are manufactured using thermal break technology to ensure the best insulation performances on the market.

RP Fineline Range

Our RP Fineline range is suitable for both architecturally complex new construction and timeless renovations – including replacement windows for properties with historic preservation requirements.
