Glassfab Tempering Services

What Glassfab Tempering Services does

Glassfab Tempering Services, Inc. is a privately held, California-based architectural glass fabricator founded in 2006 in Tracy, California, that has grown from an eight-person shop into a 300-plus employee operator of four manufacturing facilities across Tracy, CA (three sites totaling a 36-acre, 210,000-square-foot campus) and Sparks, NV. The company fabricates heat-treated (tempered and heat-strengthened), laminated (PVB and SentryGlas/SGP), insulating, decorative (ceramic frit, silk-screen, spandrel, Dip-Tech digital printing), and photovoltaic (Solarfab BIPV) architectural glass, and operates the largest Dip-Tech ERA oversized digital printer in its category. Its proprietary and licensed equipment stack includes LiteSentry Osprey on-line optical distortion inspection, waterjet/CNC cutting, and heat-soak ovens certified to BS EN 14179-1:2016, with safety glazing certified to ANSI Z97.1 and CPSC 16CFR1201.

Glassfab sells on a custom-quotation basis through a direct, sales-led motion, with architectural sales representatives serving as technical resources on codes, specifications, and product selection. The customer base is split across three primary segments—custom shower door companies, independent glass shops, and architectural glazing contractors—with named projects spanning commercial real estate (Santana Row, 505 Brannan, Bay Meadows), aviation (SFO), government (Dublin Courthouse, Emeryville Station), education (UCI, UC Merced, Mission College), healthcare (OroHealth), hospitality (Topgolf), and corporate tenants (Splunk). The company also operates a separate e-commerce hardware store (glassfabhardware.com) for shower door systems in Geneva, Vienna, and Pinnacle series. Revenue mechanics are project-based with multi-year contracts typical of commercial glazing supply; pricing is not publicly disclosed. Glassfab holds a dense stack of supplier certifications (Vitro Certified Fabricator, Guardian Select SunGuard, Pilkington, Kuraray/SentryGlas, Dip-Tech, LiteSentry) and industry certifications (IGCC/IGMA, SGCC, USGBC partner, NGA member). In 2022-2023 the company completed a documented leadership succession, installing Rob Gardner-Black as President, Patrick Tuttle as COO, and John Graham as Mountain West President, following the retirement of founding partner Mike Goldfarb.
