GR90 Sliding Door
A fiberglass sliding door at 90 mm depth — a large glazed opening that slides rather than swings, for balconies and terraces where floor space is tight.

Sliding
Glass package
Double or triple · up to 40 mm
Whole-window U-value
0.20 Calculated
Certified: third-party tested (NFRC, CSA)
Calculated: LBNL THERM / WINDOW
Project-specific: by size and glass
A slider keeps the whole leaf in plane, so it opens a wide view without sweeping into the room. The 90 mm fiberglass frame carries the glass weight while keeping the meeting stile slim and the running gear smooth.

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
Double or triple · up to 40 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.
