Why These Features Matter

Structural Integrity

Our cable support system ensures your window remains level and secure without sagging over time, protecting your home's structure.

Thermal Comfort

Insulated head and seat boards prevent cold transfer, keeping your new extended space comfortable year-round.

Design Flexibility

Choose from 30° or 45° bays, or 10°, 15°, 30°, or 45° bows to perfectly match your home's architectural style.

Comparison

Bay vs. Bow: What's the Difference?

Bay Windows

Typically 3 units with angled sides (30° or 45°). Creates a deeper projection and a more defined, angular architectural look.

Bow Windows

Usually 4-6 units joined at shallower angles (10° or 15°). Creates a gentle, sweeping curve for a softer, elegant appearance.

Common Ground

Both systems extend outward, add space, and can be configured with any combination of fixed and operable windows.

Customization

Color Options

Standard white is included, but we also offer a wide range of Gentek® and Kaycan® standard paint colours to match your home's exterior.

Common Questions

Frequently Asked Questions

Do bay/bow windows require extra support?

Yes. Because they project outward, they require proper support. We use a heavy-duty cable support system anchored to your home's framing to ensure stability and prevent sagging.

Can I replace a flat window with a bay window?

In most cases, yes. However, it may require structural modifications and a new roof skirt. Our experts can assess your specific situation during a consultation.

Are the flanker windows operable?

Typically, yes. Most homeowners choose to make the side (flanker) windows operable (casement or single-hung) for ventilation, while keeping the center large unit fixed for the view.
