What Are Bow Windows?

Bow windows are a multi-unit assembly of 4–6 lites set at equal angles to form a gentle, outward curve. This creates a wider viewing arc, increased natural light, and an elegant architectural feature that enhances both interior space and exterior curb appeal.

Engineered for GTA weather, our bow systems use reinforced mullions, insulated head/seatboards, and high-performance compression seals to maintain structural strength and ENERGY STAR® efficiency. Configure fixed centres with operable casements for ventilation, tailor projection depth, add interior seat finishes, and choose grille patterns to match your home’s style.
