Basement Windows


Basement Windows feature a single hinged sash that utilize a latch to open inwards. They are ideally used for lower levels of the home that are equal with ground level. Their superior weather-stripping helps fend against external conditions that you would typically prefer to keep outside your home.


Alpha basement windows will swing in for full ventilation and cleaning or tilt in slightly for a little fresh air. The units eliminate the need for cleaning traditional fixed lites from the exterior. The units also use high-tech compression seals for weather tightness and low sound transmission.
