Bay Windows - Multi-Chamber Construction

Multi-Chamber Construction

Higher thermal protection and more strength resulting in a more durable window are possible with our multi-chamber construction.

Bay Windows - 4 1/2″ PVC Welded Frame

4 1/2″ PVC Welded Frame

The 4 1/2″ frame provides more strength and durability than the more common 3 1/4″ frame other window manufacturers would offer. This frame which is larger enables the thermal pane to be installed closer to the inside of the house allowing a higher thermal protection as well as a stronger window.

Bay Windows - Double-Glazed Low-E Argon Gas

Double-Glazed Low-E Argon Gas

For superior levels of energy saving and home comfort as well as UV rays protection, our double-glazed glass units are Energy Star® certified.

Bay Windows - Triple Weather Seals

Triple Weather Seals

Wrapping completely the window, our seal counts three continuous layers of co-extruded flexible PVC, providing the highest level of protection from air and water infiltration.
