Glass guide: glass for shower enclosures
Share this blog:
Shower door manufacturers need to ensure they use safe, sturdy materials. Find out how we can help.
In the UK and elsewhere, shower doors are usually made out of acrylic or glass. In our opinion, glass is the better option. It's stronger and looks new for longer.
But not any old glass will do. Manufacturers use
toughened glass (also known as "tempered glass") to ensure the shower door is robust and breaks safely. This type of safety glass can be frosted or
sandblasted for extra privacy.
Why use toughened glass?
Toughened glass is around four times stronger than standard annealed glass. This makes it a safe choice for an intimate environment like the bathroom.
It's also a type of safety glass. This means that, as well as being strong, it breaks more safely than other types of glass. It takes a lot of impact to shatter a toughened glass shower door – and if it does break, it shatters into relatively harmless smithereens rather than large, sharp shards.
This is all thanks to the manufacturing process, where the glass is heated and then rapidly cooled. This excites the molecules in such a way that the glass breaks in this unique – and safer – fashion.
How thick are shower doors?
Glass doors can be anywhere between 6 mm and 12 mm. They're often on the market in 8 mm, 10 mm and 12 mm thicknesses. You'll sometimes find off-the-shelf glass that's 5 mm thick.
The thicker the glass, the sturdier it is and the more noise it blocks out. Thinner glass is the more affordable option for manufacturers and customers. It tends to be used in smaller bathrooms.
What safety regulations apply to shower doors?
Whatever the thickness of the shower door, the panels need to be tested and certified with BS EN 12150. It should have a CE marking to show compliance with EU safety standards.
These regulations cover impact resistance and performance and demonstrate your commitment to safety to your customers.
Can toughened glass spontaneously break?
Very occasionally, toughened glass spontaneously breaks. This is mostly due to nickel sulfide inclusions. These are a rare but inevitable byproduct of the manufacturing process.
For peace of mind, you can ask your supplier to
heat soak test your sheets of toughened glass. This will greatly reduce but not eliminate the chance of spontaneous breakage from nickel sulfide inclusions.
