Fixed Window — Slim Frame

A non-opening lite in the shallowest frame in the collection, so less aluminum shows around the glass.

Best for: Smaller fixed openings, transoms and window runs where the detail calls for the thinnest sightline.

Hover the drawing to see how it opens.

Overview

The 86 Series carries a shallower frame than the 100, which is what you want when the detail calls for the thinnest visible aluminum and the opening is modest. It shares the same impact glazing and finish range as the rest of the collection, so a slim-frame fixed unit sits beside a 100 Series slider without a visual break in the elevation.

  • The frame should read as a line, not a border
  • The opening is modest or sits above a door
