Commercial vs Residential Glazing: What Changes and What Doesn't

Glass is glass, until you spec it. Commercial and residential glazing draw from the same product families, insulated units, tempered, and laminated glass, but the requirements pull in different directions.

Commercial priorities

Commercial glazing lives by structural and code requirements: wind loads on curtain walls, safety glazing at entrances, spandrel and oversize units, and tight coordination with framing systems. Sizes run large, which is why our 11.5 ft x 8.2 ft maximum unit size matters to commercial buyers.

Residential priorities

Residential glazing is an energy and comfort story: triple glazing, Low-E coatings, argon fill, and warm-edge spacers that keep homes warmer, quieter, and condensation-free. Volume consistency matters most to the window manufacturers who buy IGUs by the truckload.
