Behind every finished piece of tempered glass is precision engineering, controlled heat, and expert fabrication.
In this video, glass moves through the tempering ovenโheated to extreme temperatures until it becomes red hotโtransforming from an annealed substrate into high-performance safety glazing.
From drilling and notching to edgework and finishing, GGI delivers fully customized glass solutions fabricated to specification and built for performance.
During the tempering process, annealed glass is heated to approximately 1,100โ1,200ยฐF (593โ649ยฐC) and rapidly cooled. This thermal treatment increases strength and fundamentally changes how the glass performs under impact.
What makes tempered glass different?
โข Tempered glass is up to 4ร stronger than annealed glass
โข It breaks into small fragments unlike large shards resulting from annealed glass breakage
โข Designed to reduce injury risk in human-impact areas
โข Meets CPSC 16 CFR 1201 and ANSI Z97.1 requirements
โข Tested and certified by the Safety Glazing Certification Council (SGCC)
Under ASTM C1048, fully tempered glass must meet strict compression requirements, resulting in reliable performance under wind loads and thermal stress.
Where is safety glazing required?
Building codes mandate tempered glass in hazardous locations such as:
โข Doors and all-glass entrances
โข Sidelites and storefront systems
โข Curtain walls and windows near walking surfaces
โข Glass railings and guardrails
โข Interior partitions and office fronts
โข Shower enclosures
From 3/16" (5 mm) to 3/4" (19 mm) thick glass, GGI supports customers with complex fabricationโincluding holes, notches, edge profiles, and tempering to meet safety glazing code requirements for hazardous locations.
