Single-Hung Windows
Single-hung windows are similar in look and functionality to double-hung windows. With single-hungs, however, the top sash is fixed to the frame and is non-operable. The bottom sash lifts vertically and is connected to counterbalances in the frame channel to assist with operation. With Viwinco single-hungs, both the top and bottom sashes are actual equal-sized sashes, resulting in even sight lines. Not only are they economical, they are also easily serviceable and allow for simple installation.
Our S-Series, Cambridge and OceanView single-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. Though the top sash is fixed, it can be removed from the frame using two brackets if needed to aid in installation.
