Enduring Style. Energy Smart Performance.

Fusion® windows are expertly crafted to provide year-round comfort, energy efficiency, and lasting value. Featuring fusion-welded sashes and mainframes, multi-chambered extrusions, composite-reinforced interlocking meeting rails, and insulating glass units, these windows deliver years of smooth operation and thermal protection.

You'll appreciate the quality craftsmanship and carefree maintenance. The premium vinyl mainframe and sashes won't rot, split, corrode, or pit like painted wood windows, and won't swell or warp from moisture exposure. Your windows will maintain their attractive appearance inside and out, year after year.

Reducing energy loss is often the number one reason for purchasing replacement windows. When you consider that windows are roughly 80% glass, upgrading with an insulated glass system significantly improves overall energy efficiency.

Our insulated glass packages combine Low-E (low-emissivity) glass, argon or krypton gas fills, and structural foam spacer systems to create a "warm" low-conductive edge that reduces heat loss. It's stronger and better at retaining insulating gas than conventional spacer systems.
