All our toughened safety glass is fully compliant with BS EN 12150, ensuring it meets strict British and European standards for strength, durability, and safety. Toughened glass, also known as tempered glass, is a type of safety glass that has been specially heat-treated to increase its strength compared to standard glass. During the toughening process, the glass is heated to a high temperature and then rapidly cooled, creating internal stresses that make it significantly more resistant to impact and thermal stress. If broken, it shatters into small, blunt fragments rather than sharp shards, reducing the risk of injury. Products such as 4mm toughened glass are particularly popular for both residential and commercial applications due to their balance of strength and versatility. This type of glass is commonly used in areas where safety is a priority, including doors, side panels, low-level glazing, shower screens, partitions, and furniture. Its enhanced durability makes it ideal for environments exposed to frequent use or potential impact, while still maintaining a sleek and modern appearance.
