Laminated vs Tempered: The Safety Glass Decision, Simplified.

Tempered glass is heat-treated to be 4-5 times stronger than regular glass and shatters into small, relatively harmless pieces when broken. Laminated glass consists of two glass layers bonded to a tough plastic interlayer — when it breaks, the glass stays attached to the interlayer instead of falling apart. Tempered is better for shower doors and table tops. Laminated is better for security, noise reduction, and overhead applications.

Building codes in DC, Maryland, and Virginia require safety glass (tempered or laminated) in hazardous locations including doors, sidelights within 24 inches of doors, glass near floors, shower and tub enclosures, and railings. Some locations specifically require laminated glass, such as overhead glazing and certain storefront applications. We verify the exact code requirement for your project during our free on-site assessment.

In most applications, yes — laminated glass meets or exceeds the safety performance of tempered glass. However, laminated glass is thicker, heavier, and more expensive. For applications like shower doors where the glass must break into safe pieces for cleaning and replacement purposes, tempered is the standard and practical choice. We recommend the right type based on your specific needs and budget.
