Heat-Treated Glass Solutions

Heat Treated Glass

Product Description

Heat Treated Glass is glass that has been exposed to controlled heating and cooling processes to increase strength beyond that of annealed glass. There are two main types: Heat Strengthened Glass, which is roughly twice as strong as annealed glass but retains the same breakage behavior; and Fully Tempered Glass, which is about four times as strong and is classified as safety glass due to its fragmentation behavior. The heat treatment process does not change stiffness or deflection properties—it only increases strength and durability. Fully tempered glass breaks into many small pieces, and may pose hazards if located over populated zones; for those cases, laminated safety construction may be specified. Trulite’s safety glazing products are permanently marked to certify conformance to ANSI Z 97.1 and CPSC 16 CFR 1201.  

Applications

Heat Treated Glass is used across multiple markets where higher strength or safety properties are required:

Commercial & Office Buildings – Glazing in interior and exterior walls, vision lites, and larger glass spans
Retail & Storefronts – Glass panels in storefronts and façades where wind loads or thermal stress require stronger glass
Hospitality & Hotels – Transparent partitions, exterior glass walls, pool enclosures, and high-clear vision walls
Healthcare & Institutional – Waiting areas, corridor glazing, and transparent barriers where safety is needed
Education & Institutional – Atriums, libraries, lobbies, and glass walls subject to high foot traffic or thermal gradients
Residential & Multi-Family – Glass balcony walls, glass walls, and areas requiring safety glazing properties

Features

Heat Strengthened Option – Approximately twice the strength of annealed glass, useful for thermal stress resistance and moderate loads
Fully Tempered Option – Approximately four times the strength of annealed glass and qualifies as safety glazing
Permanent Identification Marking – Every safety glass unit is permanently marked to certify compliance with glazing standards
Same Rigidity & Deflection as Annealed Glass – Glass stiffness is unchanged; design deflection behavior remains consistent
Compatibility with Laminated Safety Systems – For zones requiring containment after breakage, heat treated glass may be laminated
Fabrication Friendly – Glass can be cut or processed before heat treatment to suit architectural systems

Performance

Strength Increase – Heat Strengthened glass is about twice as strong as annealed; Fully Tempered glass is about four times stronger
Safety Fragmentation – Fully Tempered glass breaks into small, less dangerous fragments, meeting safety glazing criteria
Thermal Stress Resistance – Heat treated glass tolerates higher temperature gradients and resists spontaneous breakage under thermal load
Structural Compatibility – Enhanced strength allows for larger spans or reduced thickness in some designs
System Integration – Works with storefront, curtain wall, railing, and entrance systems while maintaining required performance
Code Compliance Markings – Permanently marked for traceability and compliance with ANSI and CPSC safety glazing standards
