Tempered Glass in Safety Windows breaks into small polygons

Tempered glass, often called safety glass, is mostly used where required by code or for a specific safety purpose. The tempering process adds cost to the glazing process. When shattered, tempered glass breaks into very small pieces, unlike regular annealed glass that breaks into long slivers and sharpened shards.

The tempering process is achieved by a series of heating and cooling cycles so that the grain of glass is reoriented from length to width. As the name would imply, tempered glass is also much stronger than annealed glass so it’s often used with larger windows where stronger glass is required.

Tempered Glass Uses

Typically, Building Codes require tempered glass next to doors, in doors, over bathtubs, and where glass is close to the floor. Tempered glass looks no different than regular annealed glass but the tempering process makes it two to three times as strong (structurally speaking).

Unless clients specifically ask for tempered glass, we use regular annealed double strength glass where tempered is not required. We always use, include, and estimate for tempered glass with our bids if we know it’s required or needed. Building Professions, when requesting a quote, please specify which windows will require tempering.
