The glass of course has to be toughened and is usually 6 mm thick although 10 mm glass can be used if a particularly large piece of glass is required. Before the glass is toughened it has to be cut to the exact size and any holes that are required have to be cut in the exact position that they are needed. You will require holes in the glass for power points and also for screws to hold the rangehood. Once the pieces of glass have been cut to size then either a paint or vinyl film is attached to the back of the glass to provide the colour. This coating on the back is usually sealed with another layer of white paint. Subsequently if you have any damage to your wall such as holes or marks the glass will usually conceal such minor flaws.The fact that the colour is applied to the back of the glass means that the colour shines through the glass which gives it a fabulous effect of depth when LED or halogen lights shine on it. Recently there have been tendencies to use a clear glass rather than the normal leaded or iron glass. I prefer the normal glass even though it distorts the colour a little as I believe ensures more depth through the refraction of light.
Another new trend with glass splashback's involves printing a photograph onto the back of the glass. I have included a couple of images in this blog to show you examples of the great results that can be achieved using this process.
The practical advantage of a glass splashback is that there are no joins so it is extremely easy to keep clean. Also the fact that it is toughened glass means that it is virtually impossible to damage and is heat resistant around cooktop area. The only other advice I would give you is to make sure that you deal with a local tradesmen whose experienced in fitting the glass as I have seen some jobs that look untidy because they have not been fitted correctly.
