Toughened Glass

Toughened Glass

High strength safety glass for many surprising functions

Romag’s toughened glass is a type of safety glass that is up to five times stronger than float glass. If broken, it  safely crumbles into smaller granular pieces instead of splintering into jagged dangerous shards as with annealed glass. This makes it ideal for windows, balustrades public shelters, digital screens, canopies or any other applications that would become dangerous in the event of breakage - particularly glass installed at height.

Processed on site at our County Durham factory using our state-of-the-art toughening plant, we manufacture toughened glass from as little as 4mm, and heat strengthened glass from 3mm, cut to size, with a range of finishing options. It can be incorporated into laminated glass, double/triple glazed units and a combination of these. Using the latest glass cutting technology, the glass can be machined in all shapes and drill configurations, from simple to highly complex with top quality edge finishes to specification.

We have over seven decades of experience toughening glass, and supply our product across the world. All our glass products have a high-quality finish with minimum distortion and bow. We also offer the option of a Heat Soak Test for added peace of mind.

Available in a range of stock, Romag toughened glass is fully tested and certified to BS EN 12150, BS EN 857 and BS EN 14179. We also offer coated glass technologies to specification. For more information, or a quotation on your next project, contact
