Simonton Bay & Bow Windows create architectural drama and interior charm by combining three or more windows at angled planes to project outward from your exterior wall. These window configurations allow natural light to flood your space, broaden sightlines, and add a cozy nook or built-in bench that enhances the room’s function and appeal. Whether you prefer bold statements or a soft curve, bay and bow windows make your home feel larger from both inside and out.

Though often grouped together, bay and bow windows have distinct geometry and styling:

• Bay windows typically use three windows (often in 30° or 45° angles) to create a dramatic outward effect.

• Bow windows use more windows (3-5 lites) at gentler, 10° angles to form a graceful curved arc.

You can configure each “lite” in the bay or bow with styles like double hung, casement, or picture windows depending on your preferences and ventilation needs.

Simonton’s bay & bow windows combine strength and insulation to perform beautifully year after year.

For example, in the 6500 Bay & Bow line, features include:

• Insulated wood mullions and heavy steel rods for structural strength and resistance to condensation.

• A rabbeted corner assembly to maintain squareness and reduce stress over time.

• Integrated water management: a weeped sill pan, recessed mullions, and sloped interior dams help channel water away from the window.

• Seatboard insulation to reduce thermal loss through the extended portion.

• Optional factory-assembled plywood roofs (for bay windows) and decorative knee braces.

In the 5500 Bay & Bow line, you’ll find similar high performance:

• Insulated wood mullions with high-tensile steel rods

• Rabbeted corners

• Weep systems and molded trim to manage moisture

• Beam support and optional roof assemblies to maintain integrity and aesthetic presentation

In the Premium Bay & Bow line, you also get the wood-look appearance merged with vinyl durability, plus all the construction and water mitigation features.

In the Madeira Bay & Bow, they employ fusion-welded vinyl frames, thick insulation in seatboards, decorative options like knee braces, optional veneer or stainable head and seat boards, and strong cable supports.

Because these windows project outward, they allow light to reach farther into your rooms, creating an expansive, airy feel. They also give you more usable interior space — often transformed into reading nooks, window seats, or soft benches.

On the exterior, they add depth, character, and distinctive architectural interest, boosting curb appeal in dramatic fashion.
