What Counts as Safety Glass (And What Doesn’t)
Safety glass is a code term, not a security term. It means glass that either breaks into small, mostly harmless cubes (tempered) or holds together in one piece when broken (laminated). Both meet ANSI Z97.1 and the federal CPSC 16 CFR 1201 Cat II standards required in hazardous locations like doors, shower enclosures, and full-height sidelights.
Safety glass does a great job keeping people from getting cut. It does very little to keep a determined person out. Breaking tempered glass still opens the hole. Stopping a break-in is a different job, and it requires different glass.
Tempered vs Laminated: Which Business Glass You Actually Need
Tempered glass is about 4 times stronger than regular annealed glass under impact, and it shatters into small pebbles instead of jagged shards. It’s what’s in most commercial business glass installations today. When it breaks, it breaks completely. Laminated glass is two panes with a plastic interlayer (PVB or SGP) sandwiched between them. When it breaks, the interlayer holds the pieces together, which is what keeps a windshield in one piece after a rock hits it.
For security, laminated wins. Tempered gives up the moment a rock, bat, or screwdriver makes contact. Laminated takes 30 to 90 seconds of sustained effort to get through, which in a smash-and-grab world is enough to end the attempt.
Security Glass Options Ranked by Break-In Resistance
- Standard tempered (¼ inch): meets safety code, breaks in one hit. Appropriate for low-risk interiors.
- Laminated safety glass (¼ inch): holds together when broken, forces 30 to 60 seconds of continued hitting to create an opening.
- Laminated security (3/8 to 1/2 inch PVB): resists prying and bat strikes, common upgrade for jewelry, cannabis, and pawn businesses.
- SGP-interlayer laminated: SentryGlas ionoplast interlayer, 5 times stiffer than PVB, rated against sustained attacks.
- Security film (4 to 14 mil): retrofit option applied to existing tempered, turns a single-pane window into a lamination-style barrier in 1 day.
- Polycarbonate hybrid (Bandit glazing): UL 972 burglary-resistant rated, used for high-risk storefronts.
Where South Texas Building Codes Require Safety Glass
- Entry and exit doors, glass panels within 24 inches of a door
- Shower and tub enclosures, any glazing within 60 inches of a floor drain
- Glazing adjacent to stairways, landings, and ramps
- Storefront windows lower than 18 inches above finished floor
- Railings and guard panels
When Standard Tempered Is Enough (And When It Isn’t)
For most low-risk business glass (interior partitions, conference room walls, back-of-house doors), standard tempered safety glass is the right call. It meets code, it’s cost-effective, and the risk of break-in is low. Our AGRS-certified glass team has been making this same call for Victoria businesses for 60 years, and the answer is usually tempered unless the address has a specific risk profile.
Upgrade to laminated or security-rated glass anywhere you have cash, inventory, pharmacy stock, or controlled products visible from the street. Also upgrade for storefronts on corner lots, alley-facing doors, and any entry that’s been hit before. Insurance underwriters track these patterns, and one prior claim often makes laminated a requirement at renewal.

What's the difference between tempered and laminated glass?
Does safety glass stop a break-in?
Tempered won’t it gives up on first impact. Laminated forces 30 to 90 seconds of sustained effort to get through, which is usually enough to end a smash-and-grab.
