Viwinco S-Series single-hung and a twin single-hung unit.

Similar in look to our double-hung windows, our single-hungs differ by having a fixed top sash and an operable bottom sash. 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.
