Lift & Slide Doors

Quality construction, thermal integrity and ease of use are standard characteristics of our lift and slide doors. Our hardwood frames create strength and durability. Our custom hardware is engineered to provide almost effortless movement — even in the heaviest constructions — by lifting the door onto its carriage and rolling or sliding the panels to open. The hardware also allows for positive stopping at all intermediate openings. Custom built to any size your designs call for, these doors instantly become a signature in the homes and buildings where they are used.

Lift/Slide Doors Data Sheet

Hardware

Operating Assembly
Door panels ride on carriages consisting of two sets of twin rollers mortised into the bottom of each moving panel. The door is raised onto its carriage by rotating the operating lever handle 180°. Lifting gear connected to a tie rod transmits motion to the carriage, lifting door. Based on G-U 933 or FFI Lift/Roll operating hardware.

Finishes: Internal carriage assembly (drive bars, wheel hub, shafts, rivets), lock kit, link rods, and connectors in zinc chromate coated steel or 304 stainless steel.

Lock face and edge stile cover are clear anodized (EV-1) or dark bronze anodized (EV-5) aluminum.
External guides and tracks are clear anodized (EV-1) or dark bronze anodized (EV-5) aluminum).

Escutcheons / Lever Handles
Escutcheons and lever handles are available in a variety of styles and configurations from various manufacturers. Configurations include levers inside and outside; lever inside, finger pull outside; thumb turn lock inside, profile cylinder outside; profile cylinder inside and outside.

Finishes: A variety of finishes are available from various manufacturers.

Optional Hardware
Screen doors, bronze tracks, aluminum thresholds, removable handles.

Glazing

All glazing is per project specifications. Duratherm can accommodate most configurations and make-ups from 1/8" single glazed to a maximum of 1" security glass.
Clear glass opening: Unit height minus 14 1/8". For clear glass width, contact factory.

Weather-Stripping

Doubled, continuous extruded silicone flap gasket set in rebate around the perimeter of the door leaf. Rotating the multi-latchpoint lever handle lowers the door and 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 lacquer, 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, low maintenance and 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.
