Types of Safety Glass Used in Commercial Buildings
Safety glass plays a central role in modern commercial construction. From storefronts to large public buildings, the right glass selection improves durability, protects occupants, and meets strict building requirements.
Peter Kapiloff explains the most common types of commercial safety glass, how they differ, and where each is typically used.
What Is Commercial Safety Glass?
Commercial safety glass is engineered to perform under stress. It is designed to reduce breakage hazards, improve strength, and support building performance in high-traffic or high-risk areas.
You’ll find safety glass in storefronts, entrances, interior partitions, exterior facades, and specialty commercial applications. Each glass type serves a specific purpose depending on location, use, and code requirements.
Tempered (Toughened) Glass
Tempered glass is one of the most widely used safety glass options in commercial buildings. It is heat-treated to increase strength and improve how it breaks.
When failure occurs, tempered glass crumbles into small, blunt pieces rather than sharp shards.
Common uses include:
- Storefront glazing
- Commercial doors and sidelites
- Interior glass walls and partitions
Because of its strength and predictable break pattern, tempered glass is a standard choice for safety glass for storefronts.
Laminated Glass
Laminated glass consists of two or more glass layers bonded with a durable interlayer. If breakage occurs, the glass remains in place rather than falling apart.
This makes laminated glass ideal for areas where retention and added protection are priorities.
Typical applications:
- Storefront systems
- Entryways
- Overhead glazing
- Security-focused commercial spaces
When comparing tempered vs laminated glass, laminated glass offers added retention and sound control, while tempered glass provides higher surface strength.
Heat-Strengthened Glass
Heat-strengthened glass is treated similarly to tempered glass but at lower temperatures. This results in increased strength compared to standard glass, though it does not meet safety-glass break standards on its own.
Common uses include:
- Curtain wall glazing systems
- Exterior building facades
- Spandrel and vision glass combinations
Security and Impact-Resistant Glass
Security glass is designed to withstand repeated impact and resist forced entry. These systems often combine laminated glass with specialized framing and anchoring methods.
They are commonly used in facilities that require additional protection while maintaining transparency.
Typical applications:
- Financial institutions
- Educational facilities
- Government and municipal buildings
- High-visibility retail storefronts
Peter Kapiloff notes that these systems balance appearance with performance, making them practical for demanding commercial environments.
Fire-Rated Glass
Fire-rated glass plays a critical role in life-safety design. It helps limit fire spread while maintaining visibility and light flow.
There are two main categories:
- Fire-protective glass, which limits flame spread
- Fire-resistive glass, which also reduces heat transfer
Common uses include:
- Stairwells
- Corridors
- Interior doors and partitions
Proper installation and certification are essential to meet code requirements.
Wired Glass
Wired glass includes a metal mesh embedded within the glass. It was historically used for fire protection but is now limited in modern commercial construction.
Newer alternatives offer improved clarity and performance, making wired glass far less common in current projects.
Insulated Glass Units (IGUs)
Insulated glass units combine multiple panes to improve thermal and acoustic performance. Safety glass types are often integrated into IGUs for added strength and efficiency.
Common uses include:
- Storefronts
- Window walls
- Exterior glazing systems
IGUs help control temperature, reduce noise, and support energy-efficient building design.
Choosing the Right Safety Glass
Selecting the right commercial safety glass depends on several factors:
- Building use and occupancy
- Location and exposure
- Performance goals
- Applicable codes
Working with an experienced commercial glass installer ensures the correct system is chosen and installed properly.
Final Thoughts
Commercial safety glass is not a one-size-fits-all solution. Each glass type serves a specific role, from storefront visibility to structural performance and fire protection.
With decades of experience in commercial glazing, Kapiloff’s Glass continues to guide architects, builders, and property owners toward glass solutions that meet both functional and design goals.
