Toughened Glass System by CRL - Strength, Safety & Style Without Compromise

At CRL, we specialise in a premium architectural glazing solution that will enhance natural light, performance and design integrity. Our most trusted innovation is by far our toughened glass system - a robust and refined choice for customers who want safety, strength and elegance in equal measure. 

Whether you’re designing a contemporary home extension, fitting in a commercial property or specifying specific structural glazing for a larger build, the CRL’s toughened glass systems provide clarity and confidence your project demands.

What is a toughened glass system?

A toughened glass system is an architectural glazing solution that uses specially treated safety glass, also known as tempered glass. This glass has been heat-treated to increase its strength, making it up to five times more durable than standard glass. 

At CRL, we use a toughened glass throughout our rooflight and bespoke glazing range that guarantees the highest levels of performance. Our toughened systems are designed to withstand impact, resist thermal stress and will break safely into blunt fragments if it is damaged - making them ideal for both residential and commercial use.
