How to prevent shower door from shattering

February 11, 2019

Over the past few years, several people have reported the spontaneous shattering of their shower screens. These reports have understandably panicked many people across the nation. With most of these instances occurring at night, it is a terrifying way to be awoken from a deep sleep! But why does this happen? Is there any way to avoid this? The first thing we need to look at is how this glass is manufactured.

How is safety glass made?

Safety glass, also known as tempered glass, is often used for shower screens. This glass is designed to shatter, to avoid having large jagged shards of dangerous broken glass. Due to this, serious injuries from shower doors shattering are very rare.

There is an incredibly detailed manufacturing process to achieve this. During the process, the glass is heated to around 620 °C (1,148 °F) and then rapidly cooled with high-pressure air drafts. This makes tempered glass up to 5 times stronger than glass that hasn’t gone through this process.

What makes safety glass shatter?

In very rare cases, foreign materials get trapped inside of the glass when it’s manufactured. This can cause the glass to shutter over time for no apparent reason. Unfortunately, there is no easy way to find evidence of this in your shower door.

Tiny chips or cracks can appear due to a bump or just general wear and tear. These may not cause the door to shatter immediately. Changes in temperature causes glass to expand and contract. These movements, or vibrations caused by noise, may lead to the door shattering.

What can I do to prevent my shower door from shattering?

Check your glass door every few months. Be sure to look at the edges of the screen for any minuscule chips or cracks. You should also make sure that all brackets and screws are correctly in place.

We have recently had our front door and windows replaced by Jack of Glass. They were great. The communication was amazing, we knew every step of the way what was happening and they left place spotless. Our new door and windows have completely changed the house. Very happy and would recommend to anyone.

Jack of glass have recently replaced all my windows efficiently and to a high standard. The price was also very reasonable. The customer service was outstanding along with the services they provide. Highly recommended.

Mr Bennett

I had to replace a small double glazed panel in a window. I though it would be difficult to get anybody interested as it was such a small job. However, Jack of Glass did the work. They visited the house to take the measurements, ordered the replacement glass and fitted it all very efficiently and at a reasonable cost. I will use them again.
