What is A Double-Hung Window?

The double-hung window style has two sashes that operate vertically for ventilation from either the top or bottom of the window unit. Both sashes may tilt in for safe and easy cleaning from inside the home. Balancers counter the weight of the sashes to provide easy operation and to allow the sashes to remain open in any position.


What is a Single-Hung Window?

On single hung windows, the top sash is fixed in place and does not move. The bottom sash is operable. 3000 and 6000 series windows are single hung.
