Laminated Glass vs Tempered Glass: The Core Difference (Containment vs Shatter)

While both laminated glass and tempered glass are classified as safety glass, they are engineered to solve different safety challenges. The most important distinction between them lies in how the glass behaves after impact.

• Laminated glass is designed for containment. Even when cracked or broken, the interlayer holds the glass fragments together, maintaining a barrier that continues to provide protection.
• Tempered glass is designed for safe breakage. It offers high initial strength, but when it fails, it shatters completely into small, blunt pieces, eliminating sharp edges but losing structural integrity.

Understanding this difference is key when selecting the right glass for security, safety, and performance requirements.

✅  Choosing the right glass type depends on your specific project needs. If you need maximum security and soundproofing, laminated glass is the better option; if you want cost-effective safety glass with high impact resistance, tempered glass is often the preferred choice. 

Can Laminated and Tempered Glass Be Combined?

Yes. In some applications, glass can be both tempered and laminated, combining the strength of tempered glass with the containment and safety benefits of laminated glass.

This type of glass assembly is often used in high-performance architectural glazing, where impact resistance, post-break safety, and durability are all required. The exact configuration depends on factors such as glass thickness, interlayer type, framing system, and project-specific requirements.

Tempered laminated glass is commonly specified for commercial buildings, overhead glazing, and areas where enhanced safety and code compliance are critical.

Safety Standards and Code Considerations

When selecting safety glass, it’s essential to consider applicable building codes and industry standards. Both laminated and tempered glass must meet specific safety requirements depending on the application and location.

Common safety glazing references include:

• ANSI Z97.1 – Safety glazing materials used in buildings
• CPSC 16 CFR 1201 – Consumer product safety standard for architectural glazing
• ASTM C1172 – Standard specification for laminated architectural flat glass

Always verify local building codes and project specifications to ensure the selected glass type meets all safety and compliance requirements.

Frequently Asked Questions 

What is safer: laminated or tempered glass?

Both laminated and tempered glass are classified as safety glass, but “safer” depends on the type of risk involved.

Laminated glass provides better protection against forced entry and post-break hazards because it holds together when shattered. Tempered glass, while very strong, is designed to break into small, blunt pieces that reduce injury risk, making it ideal for interior and high-traffic areas.

Can laminated and tempered glass be used together?

Yes. Many projects use both types of glass depending on the application. For example, laminated glass may be specified for exterior windows to enhance security and sound control, while tempered glass is often used for interior doors, partitions, or shower enclosures where impact resistance is the priority.

In some cases, tempered laminated glass is used to combine both strength and post-break containment in a single assembly.

Which glass type is better for soundproofing?

Laminated glass is better for sound reduction because the plastic interlayer helps absorb sound vibrations. This makes it especially effective for buildings near busy streets, airports, or other high-noise environments.

Is laminated glass more expensive than tempered glass?

Generally, yes. Laminated glass tends to be more expensive due to its layered construction and the additional materials involved. Tempered glass is typically more cost-effective, though pricing can vary based on thickness, size, and project specifications.

Where should I use tempered glass?

Tempered glass is commonly used in applications where safety glass is required, but enhanced security is not the primary concern. Typical uses include shower doors, interior glass partitions, tabletops, shelves, and side or rear vehicle windows.

Does laminated glass block UV rays?

Yes. Laminated glass can block up to 99% of harmful UV radiation, helping protect interiors, furnishings, and finishes from fading and sun damage.
