This sliding basement window by Wellcraft can be paired with many of our window well models for a fully IRC compliant egress system. It also helps your basement living area feel more open and comfortable by letting in outdoor air and natural light.

The high efficiency of this window is achieved with the use of ¾" double-glazed insulated Low-E glass. The maintenance-free, rugged vinyl frame is rust proof and doesn't need to be painted, making it easy to use on either a retrofit or new construction. The window's sash is also removable for cleaning and the included fiberglass half- screen is removable from inside the room.
