Data Sheets

Operating Assembly
Window sashes ride on carriages consisting of two sets of twin rollers mortised into the bottom of each moving sash. The sash 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 sash. 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 are 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.

Egress: Properly-sized units meet egress requirements using standard hardware configuration.

Lever Handle
Standard handles are solid brass.

Finishes: Satin Nickel (US15), Polished Brass (US3), Satin Anodized Aluminum (US28).

Optional Hardware
Keyed locks.

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

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

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.
