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.
