Tilt-Turn Windows


Tilt-turn windows have been extremely popular in Europe for over 50 years and are gaining popularity throughout North America and the rest of the world. The Kolbe Teutonic® Series offers a tilt-turn window suitable for commercial construction. The specialized hardware system allows the sash to tilt in at the top, which provides ventilation while maintaining a secure environment. The sash can also turn, or swing into the room, which provides more extensive ventilation and a wide opening for emergency escape. If desired, the tilt-turn can be manufactured as a tilt-only hopper unit, allowing ventilation only from the top, or as a turn-only unit, allowing ventilation from the side like an inswing casement.

This tilt-turn corner section has a North American frame.

Hardware & Screens

Various types of hardware are available for tilt-turns. The first is a standard handle, which allows the sash to be turned or tilted in and opened. The hardware wraps completely around the sash, providing multiple locking points between the sash and frame.

The second is a keyed lock handle which can completely lock all operation, allow tilt-only operation, or allow operation only when the key is inserted. A key must be used to place the unit into the turn position.

Optional sill-mounted hardware has the handle on the bottom instead of the side. It features a longer lever arm and an integrated positive control that operates the window without using force.
