The classic colonial window style. Both top and bottom sash open vertically for controllable ventilation and tilt inward for easy cleaning of the exterior panes from right inside your home. No more squeegees and ladder climbing. Also available in single hung style, where only the bottom sash operates. This option reduces cost without significantly changing the appearance of the window.
The double hung Ottawa windows offer functional benefits for areas such as walkways where outward opening windows would be an impediment. This functionality comes with absolutely no compromise on style or esthetic appeal!
