Tempered safety glass is used in hazardous locations that could be impacted such as in doors and within 24″ of a door. It is also required in sidelites and transoms. This glass can is an excellent choice for exterior or windows or areas where additional security is required.
Order custom tempered glass cut to size from Liberty Shielding for doors, windows, tabletops, shelves, partitions, commercial glazing, and other architectural applications requiring increased strength and safety.
Tempered glass—also called toughened glass or tempered safety glass—undergoes a controlled heat-treatment process that increases its strength compared with ordinary annealed glass.
If broken, tempered glass is designed to fracture into relatively small pieces rather than the large, sharp shards typically produced by annealed glass. This makes it an appropriate safety-glazing material for many locations where building codes require impact-resistant safety glass.
Our tempered glass meets applicable impact-safety requirements of ANSI Z97.1 and CPSC 16 CFR Part 1201.

Tempered glass is heat-treated safety glass manufactured by heating annealed glass to a high temperature and then rapidly cooling its surfaces.
This process creates compressive stresses at the surfaces of the glass and tensile stresses within the interior.
The result is glass that is substantially stronger than comparable ordinary annealed glass and has different breakage characteristics.
When annealed glass breaks, it can form large, sharp pieces.
When fully tempered glass breaks, it is designed to fracture into many relatively small pieces, reducing the risk of severe cutting injuries.
This is why tempered glass is commonly specified as safety glazing in doors, shower enclosures, certain windows, and other hazardous locations.
One of the most common questions when buying replacement glass is whether to choose tempered or regular annealed glass.
| Feature | Tempered Glass | Annealed Glass |
|---|---|---|
| Strength | Approx. 4–5× stronger | Standard |
| Heat Treatment | Yes | No |
| Breakage | Small fragments | Larger, sharper pieces |
| Safety Glazing | Appropriate tested products can qualify | Generally no |
| Cut After Tempering | No | Yes |
| Common Uses | Doors, showers, furniture, commercial glazing | General glazing where safety glass isn't required |
For applications where safety glazing is required, ordinary annealed glass should not be substituted for an appropriate tempered or laminated safety-glass product.

Custom-cut tempered glass can be used for:
Glass installed in or around doors is one of the most common applications for tempered safety glass.
Because doors and adjacent glazing can be subject to accidental human impact, building codes frequently require safety glazing in these locations.
Tempered glass provides the combination of visibility, increased strength, and safety breakage characteristics needed for many door applications.
Applications include:
Always verify the applicable code and glass requirements for your specific opening.
Tempered glass is commonly used in windows located in areas where impact safety is required or additional glass strength is desired.
Examples can include qualifying:
Not every window requires tempered glass. Requirements depend on the window's dimensions, location, surrounding conditions, and applicable building code.
Tempered safety glass is widely used in shower doors and enclosures because these applications require safety glazing capable of reducing the hazards associated with accidental breakage.
Custom tempered glass may be appropriate for compatible:
Shower applications often require specific glass thicknesses, edgework, holes, notches, or hardware preparations.
All fabrication must be completed before the glass is tempered.
Custom-cut tempered glass is also an excellent choice for furniture applications because of its increased strength and clean appearance.
Common applications include:
Appropriate thickness and edge treatment should be selected according to the size, support conditions, and intended use of the glass.
Commercial buildings frequently use tempered glass in locations subject to pedestrian traffic or accidental impact.
Applications include:
Tempered and laminated glass are both commonly used as safety glazing, but they behave very differently when broken.
Tempered glass is heat treated for increased strength. When broken, it fractures into relatively small pieces and generally falls out of the opening.
Laminated glass consists of multiple glass layers bonded to an interlayer. If the glass breaks, the interlayer helps hold the broken pieces together.
This makes laminated glass particularly useful where post-breakage glass retention, security, or additional acoustic performance is desired.
Neither product is universally better—the correct choice depends on the application.
Tempered glass provides substantially greater resistance to impact than comparable annealed glass and can meet recognized impact-safety glazing standards such as ANSI Z97.1 and CPSC 16 CFR Part 1201.
However, the term “impact resistant” can also refer to hurricane and windborne-debris glazing, which requires different testing and often uses specialized laminated glass assemblies.
Standard tempered safety glass should therefore not be assumed to provide hurricane, forced-entry, ballistic, or security-glazing performance unless the specific product and assembly have been tested for those requirements.
Our tempered safety glass is manufactured to meet applicable impact-resistance requirements of:
ANSI Z97.1 establishes specifications and test methods for safety glazing materials used in buildings.
CPSC 16 CFR Part 1201 establishes federal safety requirements for architectural glazing materials used in certain hazardous locations.
The appropriate glazing type and category should always be selected according to the requirements of the specific installation.
All cutting and fabrication must be completed before the glass undergoes the tempering process.
Once tempered, the internal stresses that give the glass its strength prevent conventional cutting, drilling, or modification.
Attempting to cut or drill fully tempered glass will typically cause the entire panel to break.
For this reason, verify all dimensions and required fabrication before placing your order.
Because tempered glass cannot be resized after manufacturing, accurate dimensions are extremely important.
When ordering replacement glass:
Do not automatically order glass to the exact dimensions of the surrounding opening. Many glazing systems require clearance around the glass.
If replacing an existing panel, measuring the original glass is generally preferable when possible.

Yes. Fully tempered glass is generally approximately four to five times stronger than comparable annealed glass, although actual performance depends on thickness, dimensions, edge condition, loading, and other factors.
Tempered glass manufactured and tested to the applicable safety-glazing standards can qualify as safety glazing.
Our tempered safety glass meets applicable requirements of ANSI Z97.1 and CPSC 16 CFR Part 1201.
Instead of producing the large, sharp shards associated with ordinary annealed glass, tempered glass is designed to fracture into many relatively small pieces.
Tempered glass must be cut before tempering. Once the tempering process is complete, the panel cannot normally be cut, drilled, or resized without breaking.
Tempered safety glass is commonly used for shower doors and enclosures. The specific thickness, dimensions, fabrication, and hardware requirements depend on the shower system.
Yes. Tempered glass is commonly used for tabletops, desks, shelves, and other furniture applications because of its increased strength and safety characteristics.
No. Standard tempered safety glass should not automatically be considered hurricane-resistant glazing. Hurricane glazing requires specific testing for windborne debris and cyclic pressure and commonly uses specialized laminated assemblies.
No. Standard tempered glass does not provide the protection of tested bullet resistant glazing. Ballistic applications require purpose-built bullet resistant glass designed for a specified threat level.
