GR85 Casement Window
The 85 mm casement, detailed with an integrated pleated insect screen — Passivhaus-grade thermal depth in an outward-opening window that keeps insects out without a separate storm frame.

Certified: third-party tested (NFRC, CSA)
Calculated: LBNL THERM / WINDOW
Project-specific: by size and glass
The same deep 85 mm fiberglass frame as the dual-action window, in an outward casement with a factory-integrated pleated screen. It suits Passivhaus elevations where operable ventilation and insect protection both matter.

Certified values are published as NFRC and CSA testing completes. Calculated values come from LBNL THERM and WINDOW models of the specific assembly. Project-specific values depend on size and glass package.
Glass & glazing options
Triple or vacuum · up to 42 mm. Low-E and solar-control coatings, warm-edge spacers, argon or krypton fill, laminated and acoustic packages to suit the project.
Hardware
German tilt-turn hardware with concealed hinges and multi-point locking. Handle finishes in nine anodized and powder-coated options — see Finishes.
Sizes & configurations
Single and coupled multi-lite arrangements. Maximum sizes are governed by the weight of the glass package and, for the A-Series, the design wind load; see drawings for limits.
Drawings & details
Head, jamb, and sill sections, anchoring and interface details, and DXF profiles available on request while the drawing library is finalized.
Installation
Rough-opening tolerances, substrate requirements, and air-barrier interface guidance follow the F-Series installation manual. See Air Barrier Interface and Installation.
