Vent Windows

When you close one of these windows, you'll notice how the sash pulls tightly into the frame and against multiple synthetic ultra-compression weather strips. The tight seal prevents air and moisture from getting in and provides you with a much higher level of home security, making them an excellent choice for bathroom and basement window replacement. Each operating sash comes standard with a commercial-grade, multi-point lock system, providing additional security and closure for less visible window placements in your home, such as basement windows and bathroom windows. Not interested in vinyl windows?  Window Nation's vent windows are also available in wood. All windows are constructed using stainless steel dyes and manufactured with 100% uPVC virgin vinyl that is fully fusion-welded using state-of-the-art four-point welding equipment. Box and I-beam construction provide superior strength and rigidity while increasing the insulating performance. High-strength automotive-grade glazing beads actually tighten as the wind and elements blow against them.
