When you purchase glass display cases you must identify whether the glass used in the case will fulfill your display needs or not. Irrespective of the type of your cabinet whether tall, small, cube or wall mounted, you must know the type of glass used for your safety as there are several types of glasses available in the market which are used in glass display cabinets in UK.
Types of glass
Annealed Glass
Annealed glass also known as plate or float glass is the type of glass used in windows. This glass if broken cracks into sharp shards which can be very dangerous. Most of the low-priced display cabinets have annealed glass on the front and sides.
How it is made?
The glass first goes through heating process and then it is cooled. The way this is created it contains no breaks or grains into sharp shards.
Tempered Glass
Tempered glass is produced just like the annealed glass; however, this glass is heated twice in order to harden it. It also realigns the molecules so if in case the glass breaks it separates into small multi-sided pieces which is way safer than sharp shards.
Laminated Safety Glass
Laminated safety glass holds together when broken due to polyvinyl butyral or ethylene-vinyl acetate film that is laminated between the layers of the glass. This glass is also used in automobile windows. The inner layer of the glass softens the blow and prevents it from shattering when broken.
Laminated glass can also be designed to resist bullets by applying multiple glass layers & inter-layer film. Usually these glasses are used to avoid visual distortion that is quite possible with tempered glass. However not all can afford to have these glasses as these are quite costly as well as take long to cut. Laminated safety glass can prove to be effective in preventing thieves when used in retail displays.
UV Blocking Glass
UV blocking glass blocks 99% of UV radiation. It has sharp filter cut off for almost no colour distortion in the visible light region and can be applied to borosilicate glass for heat resistant applications. These glasses are exceptionally durable and are cracking and abrasion resistant.
