Single Hung Windows
Single-hung windows offer all the features and benefits of double hung windows, with one difference: only the bottom sash opens by sliding upward. The ventilation opening can be adjusted from a small area to one-half of the window area.
Double Hung Windows
Double-hung windows are often used on a second floor and both sashes tilt in for easy cleaning from the inside of the house. It also allows the bottom of the window to be raised letting the cooler air inside and the top sash to be lowered letting the warmer air out.
Fixed or Picture Windows
Often selected for decoration or in combination with other windows, fixed windows don’t open or vent. A circular or hexagonal window can be strategically placed to enhance a view or the exterior architecture of your home. Or, in a window wall, a fixed window can be flanked by venting units and topped with smaller fixed units, called transoms.
