Basement hopper windows are designed to upgrade the basic windows provided during home construction. Our superior quality basement hopper windows are far more energy efficient than normal basement windows, and provide much greater security. Our hopper windows are less susceptible to damage and breakage than awning designs. Unlike the light-grade slider windows usually supplied, our hopper windows provide full ventilation without direct drafts or annoying wind gusts. And because they tilt in, they do not protrude onto walkways.
