Glass

The unit does the work.

A window is only as good as the insulating unit inside it. Double, triple, and vacuum IGUs with Low-E and solar-control coatings, warm-edge spacers, and argon or krypton fill, matched to the frame and the climate.

GR85 glazing pocket section

Triple & vacuum IGUs

A hybrid pocket stacks an outer lite, an argon cavity, and a vacuum unit into a 42 mm frame — wall-level insulation without wall-level thickness.

Coatings & fill

Low-E and solar-control coatings tune the SHGC to the orientation; argon or krypton fill and warm-edge spacers keep the edge warm.

Laminated & acoustic

Laminated impact glass for the coastal A-Series, plus acoustic interlayers where the site is loud. Packages are project-specific.

Glazing options and exact U-values are governed by the assembly. See Performance for how values are labeled, and each product page for its glazing pocket.
