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.

Tilt/Turn Windows Data Sheet

Hardware
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.

Insect Screens
All glazing is per project specifications. Duratherm can accommodate most configurations and make-ups from 1/8" single glazed to a maximum of 1 3/4" security glass. Clear glass opening: Unit height minus 7 3/4", unit width minus 6 3/4".

Weather-Stripping
Double continuous extruded silicone flap gasket set in rebate around the perimeter of the sash. Engaging the multilatchpoint espagnolettes compresses the weather-strip to ensure a tight seal.

Wood Species & Finishes

Duratherm sources all materials by project — from only providers we know and trust. Many of our woods are from Forest Stewardship Council® (FSC- C108949) certified sources. We obtain others from sustainably harvested plantations. Fourteen domestic and exotic wood species offer a wide range of colors, grains, and textures.

Please contact us for information about finishing options (including paint, Sikkens, clear laquer, stain, bleach stain, oil, etc.) and to discuss the use of a species not in our standard offering. We consider availability, durability, machining, and gluing characteristics to determine the feasibility of your choices.

Glazing

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.
