What is BS EN 12150 glass?

BS EN 12150 glass is a type of safety glass that meets the requirements outlined in the European Standard norm EN 12150. It is designed to minimize the risk of injury when it breaks by shattering into small, less harmful pieces. This glass is commonly used in various applications where safety is a concern, such as glass doors, windows, and partitions.

Composition and Manufacturing Process

BS EN 12150 glass is made using a specific composition and manufacturing process to ensure its safety properties. It is typically produced by heating ordinary float glass to a high temperature and then rapidly cooling it, a process known as thermal tempering. This creates a balanced internal stress distribution within the glass, resulting in its improved strength and safety characteristics.

Strength and Safety Benefits

One of the main benefits of BS EN 12150 glass is its increased strength compared to regular annealed glass. The tempering process makes it up to five times stronger, allowing it to withstand higher impacts and pressures without breaking. When BS EN 12150 glass does break, it fractures into small blunt-edged pieces rather than sharp shards, reducing the risk of serious injuries. Additionally, this glass has a higher resistance to thermal stress, making it suitable for use in areas with fluctuating temperatures.


BS EN 12150 glass is widely used in both residential and commercial settings. In homes, it is often found in shower enclosures, tabletops, glass balustrades, and shelves. In commercial buildings, it is commonly used as shopfronts, office partitions, and display cases. Its safety properties also make it an ideal choice for public spaces, such as shopping malls, airports, and hospitals, where there is a higher risk of accidents.
