Double-Hung Windows
Double-hung windows have two or more sashes that slide vertically. Double-hung windows allow for both sashes to slide in separate tracks, while the single-sliding option only allows for one sash to slide while the other remains fixed. An advantage to slider windows is their ability to adjust ventilation from being totally open (50% max) to reducing air flow to a small opening. The sashes of a double-hung window remain held in place through the use of counterweights, friction, or pretensioned springs. Variations on the sliding window are: double or single tracks, screens on the interior or exterior unit, and the possibility of a pivoting hinge on the sash.
