ProVia Endure Series Vinyl Windows

The Endure is ProVia's flagship vinyl window and our most recommended window for Northern Virginia installations. It addresses every shortcoming of standard vinyl windows: SunShield vinyl stays cool in direct sun (standard vinyl can warp), FineLine welding creates virtually invisible corner seams, and the 1" ComforTech DLA-UV glass unit delivers significantly better energy performance than dual-pane alternatives.

The frame uses graphite-infused foam and INNERGY fiberglass-reinforced thermal inserts to break thermal bridging through the frame itself - an area most window companies ignore. The result is a window that performs closer to premium fiberglass or wood in energy testing, at a vinyl price point. Available in the same style range as the Aspect, with additional interior wood grain laminate options.
