Last updated: August 2026 dataWired cast and rolled glass combines the textured surface of the rolling process with an embedded wire mesh, historically the standard product for fire-rated glazing in industrial and institutional buildings. The wire mesh provides fragment cohesion during a fire event, allowing the glass to maintain integrity and limit flame spread for a rated period, though modern fire-rated glazing standards increasingly favor ceramic or borosilicate alternatives. Replacement and renovation markets in older commercial and industrial facilities remain the primary demand driver for this product.

Products intended for fire-rated assemblies in the US should carry listings from recognized testing laboratories (such as UL) confirming compliance with ASTM E163 or the applicable fire-test standard. The listing must match the specific wire pattern, thickness, and frame system specified in the building design, as fire ratings are assembly-specific.
Updated safety glazing standards (ANSI Z97.1, IBC) found that wired glass's impact resistance is insufficient for hazardous locations, and fire-rated tempered, laminated, and ceramic glazing products now offer both fire integrity and impact safety in a single product. Wired glass remains in use primarily for replacement in existing rated assemblies where the original specification must be maintained.
