We use WeatherWeld® Vinyl Replacement Windows. Their high-technology welded sash construction delivers superior trouble-free performance, year after year. This state-of-the-art fusion-welding process creates a one-piece sash that's permanently sealed against the weather.

WeatherWeld® windows eliminate drafts and cold and hot spots that can occur with less thermally efficient windows. They also reduce outside noise entering your home making it more enjoyable and comfortable, too.

Window cleaning is easy with WeatherWeld® Vinyl Double Hung Windows. When you release the tilt-in latch the sash opens inward and sits firmly in place for safe, quick, easy cleaning of the outside glass and sash. After cleaning, you lift the sash, give a gentle push and the latch locks the sash securely in place. No ladders, no uncomfortable bending or stretching - just easy cleaning.

Multi-chambered frame and sash construction increases thermal performance - creates insulating air spaces which make your home more comfortable, your windows stronger and more secure. The 7/8" glazing of Weatherweld windows is nearly 25% thicker than most ordinary windows used in new homes. For even greater efficiency, WeatherWeld® Vinyl Windows are available in Double or Triple Comfort -E2® Low-E Glass and other high-performance glazing options.

Decreasing radius sash locks securely lock your windows and pulls the sash together, tightly meshing the weather-stripping to create a weather-tight seal.

Fusion-welding creates a superior window with permanently sealed sash corners. The welded corners stay square and true adding strength to the entire window for an extremely strong, smooth operating and durable window.
