Bespoke Secondary Glazing for Bay Windows

Does your bay window feel like the coldest part of your home? Bay windows are a stunning architectural feature, but their large surface area and multiple glass panels make them a primary source of heat loss and noise infiltration. Because of their complex angles, traditional replacement glazing can be incredibly expensive and often ruins the original aesthetic of the property.

At EcoShield, we specialize in bespoke secondary glazing designed specifically for the unique geometry of bay windows. We provide a discreet, high-performance barrier that keeps the heat in and the noise out, without changing the look of your home from the outside.

Solving the “Cold Bay” Problem

Most bay windows—especially in Victorian and 1930s homes—suffer from significant draughts. Because the window “projects” out from the main wall of the house, it is exposed to the elements on three (or five) sides.

• Eliminate Draughts: Our custom-fitted aluminum frames create an airtight seal, stopping the “chill” that often pools around bay window seating areas.

• Superior Thermal Insulation: By creating a managed air cavity between your original window and our secondary unit, we reduce heat loss by up to 65%.

• Preserve Your View: Our slimline profiles are designed to align perfectly with your existing mullions and transoms. You get all the comfort of modern glazing while keeping the classic “curb appeal” of your original windows.

Noise Reduction for Busy Streets

If your bay window faces a road, it acts like a giant acoustic “catcher’s mitt,” bringing traffic noise directly into your living room.

Our bay window secondary glazing uses acoustic laminate glass and a precision-engineered air gap to dampen vibrations. This setup is significantly more effective at soundproofing than standard double glazing, reducing external noise by up to 80%.

Custom Solutions for Every Shape

No two bay windows are exactly the same. We offer tailored designs for:

• Canted Bay Windows: Typical 3-sided bays with angled side units.

• Square Bay Windows: Common in modern and 1930s builds.

• Sash Bay Windows: We ensure our secondary units slide perfectly in line with your original sashes for full ventilation.
