Tilt / Turn Windows
Achieve design and ventilation flexibility with custom tilt-turn hardwood windows.
Operating with a single handle, tilt-turn windows provide two methods of operation — tilting inward, open from the top like a hopper window or turning and opening wide like a traditional in-swing casement window. Custom designed, concealed hardware delivers secure locking and is easy to use.

Data Sheets
Operator
Multi-latchpoint fully-concealed locking hardware controlled by single lever handle control. Horizontal and vertical perimeter locking points ensure weather-tight performance and security. In the turn mode, an adjustable friction stay holds window in any open position from 0° to 90°. In the tilt mode, the sash projects in at head approximately 10° to provide controlled ventilation without compromising security. Egress: Available as quick-release pin at sash connection.
Lever Handle
Operating hardware accepts any lever handle with 43mm attachment spacing and 7mm sq. spindle. A wide variety of styles and finishes are available from various manufacturers.
Optional Hardware
Custodial locks, sash restrictors, removable operating handle.

Glazing Configurations
All types and configurations are available to use in Duratherm windows and doors. From single monolithic to triple glazing, laminated, curved-in-place, electrochromatic switchable – virtually any type or configuration commercially available – and perhaps even some that are not.
Glazing Methods
Dry Glazing
Specially developed extruded silicone gasket sets the glass by compression. Our proprietary system is long-lived, has low maintenance, and stays water resistant.
Wet Glazing
Our special silicone wet glazing compound bonds to the glass for long-lived sealing. Plus our continuous extruded silicone weatherstrip runs around the frame perimeter, and the seal is not compromised by seasonal expansion and contractions of the sash and frame.
