How to Become
a Glazier.
Installs glass — storefronts, curtain walls, mirrors, custom windows. Precision, height, weight. Strong IUPAT presence.Here's the honest path — from zero to journeyman, with the numbers and warnings that nobody puts in the brochure.
The Path.
The union apprenticeship is the gold standard — earn while you learn, no debt, progressive wage increases. Here's the honest step-by-step for the IUPAT — Glass and Metal Workers branch path.
Apply to an IUPAT Glaziers apprenticeship — the Glass and Metal Workers branch of the Painters and Allied Trades union runs 3–4 year programs. Glaziers are one of the less-talked-about construction trades, which means less competition for apprenticeship slots.
Complete your OSHA 10 and scaffold certifications in the first year — glazing work frequently involves elevated work on commercial buildings. You'll be on swing stages and scaffolding regularly.
Learn both storefront and curtain wall systems — storefront is the most common work (commercial storefronts, interior glass partitions, shower enclosures). Curtain wall is the high-end specialty: the all-glass facades on office towers. They use different materials, different tools, and different rigging.
Get your lift operator certification — glazing crews use articulating boom lifts, scissor lifts, and vacuum-panel lifts. Being certified expands your usefulness on any commercial site.
Learn glazing sealant and waterproofing — properly installing and sealing curtain wall systems against water infiltration is a technical skill that distinguishes competent glaziers. Leaky glazing is an expensive problem.
Make journeyman — glaziers are routinely the least-discussed trade on a commercial site and consistently underestimated. A glazier who can read curtain wall shop drawings and manage a vacuum-panel installation crew is genuinely rare.
The Money.
What the Brochure Leaves Out.
Heavy lifting is a daily reality. Large insulated glass units routinely weigh 200+ lbs.
Cuts. Always. Even with gloves. Plan for it.
Heights — curtain wall installation often happens at significant heights.
