What are Double-Hung Windows?

Traditional, stylish and functional. Double-hung windows consist of two operable sashes that move up and down. They are connected to counterweights housed in the frame that assist with operation. A lock and keeper are located on the meeting rail of the unit where both sashes meet, to secure the window in a locked position when the lock is engaged. Double-hung windows are one of the most versatile styles in our product offerings and look great as the only style or as a complement to other styles.

Our S-Series, Cambridge and OceanView double-hung windows come standard with Viwinco patented Tilt-n-Lock technology for single-handed operation and the cleanest sight lines in the industry. The Tilt-n-Lock does away with traditional tilt latches in favor of an easy to use one-handed system. The Tilt-n-Lock provides unobstructed views by housing the tilt latches and reinforcement inside the meeting rail. At the 0-degree position the sash is securely locked and the tilt latches are housed in the jambs for added security. At the 150-degree position, the hidden tilt latches are engaged but the sashes are unlocked allowing the sashes to be lifted. At the 180-degree position, the hidden tilt latches are disengaged from the jambs allowing the windows to be tilted inward for easy maintenance.
