This Northview Vinyl Ranch Window is constructed of energy-efficient polyvinylchloride (PVC) which will not warp, peel, or corrode and will provide years of trouble-free operation and performance. This versatile window can be installed as an awning, hopper, or left and right swing window, and its fusion-welded frame and sash corners add strength and help to prevent against air and water leakage. The manual operated inswing window features concealed, friction adjustable hinges and diecast metal sash locks that, combined with the unique double-contact weather strip, create a weathertight, secure window you can enjoy for years to come. The 3/4-inch perimeter nail flange makes for easy installations, or you can order the window with the nail flange removed for remodeling applications.
