Bay Windows - Multi-Chamber Construction

Multi-Chamber Construction

Our multi-chamber construction allows for superior thermal protection and also provides greater overall strength to the window resulting in a more efficient and more durable window.

Bay Windows - 4 1/2″ PVC Welded Frame

4 1/2″ PVC Welded Frame

Our 4 1/2″ frame is stronger and more durable than the standard 3 1/4″ frame available from most other window manufacturers. Our larger frame allows us to put the thermal pane closer to the inside of the house resulting in better thermal protection and a stronger window.

Bay Windows - Double-Glazed Low-E Argon Gas

Double-Glazed Low-E Argon Gas

We use Energy Star® certified, double-glazed glass units that provide the highest levels of energy efficiency, home comfort, and also protect against UV rays.

Bay Windows - Triple Weather Seals

Triple Weather Seals

Our window seal is made up of three continuous layers that wrap seamlessly around the entire window. The co-extruded flexible PVC seals offer the highest degree of protection from air and water infiltration.

Bay Windows - Tremco® EnerEDGE® Warm-Edge Spacer

Tremco® EnerEDGE® Warm-Edge Spacer

Tremco® EnerEDGE® Warm-edge spacer system is highly durable and possesses a lower thermal conductivity value. This results in superior thermal performance when compared to the traditional, standard aluminum spacer bar.

Bay Windows - High Gloss Finish

High Gloss Finish

We use the highest grade PVC powder and fabrication techniques which result in a high gloss PVC finish. As a result, our windows are easier to clean, more durable, and won’t fade or yellow over time.

Bay Windows - Foam Insulated Post for Bay Window

Foam Insulated Post for Bay Window

We insulate our posts with foam to give you optimal energy efficiency. This, combined with our advanced, superior structural construction is what makes our windows Energy Star® High Efficiency rated.

Bay Windows - Exterior Bay Window Angle Mullion

Exterior Bay Window Angle Mullion

Our angled mullion allows you to get all the benefits of a beautiful bay window and ensures you get Verdun's pattened single structural frame. Our windows are never screwed together. We engineer one, solid structural frame to give you better protection and more light for your windows.

Bay Windows - Smooth Edge, “One-Click”, Easy-to-Remove Screen

Smooth Edge, “One-Click”, Easy-to-Remove Screen

Our “One Click” screens are the easiest screens to operate in the industry. With their durable, yet elegant, aluminum finish, these screens won’t warp or break down over time like some of the competition.
