Many people who have experienced self cleaning glass are asking themselves this question: Will Pilkington K glass and other self cleaning glass bring an end to the common window cleaner? It seems like glass that cleans itself would be a complete impossibility and it is something that has to be seen to be believed.

Once you have seen how it works and understand the remarkable technology behind this type of glass, you will understand why people ask the question. The secret behind how it works is in the microscopic world of nanotechnology.

What we cannot see with our eyes is that normal glass is actually very porous. Using a sophisticated nanotechnological process, normal glass is coated with an ultra thin sheet of a special substance that does two things that make it repel dirt.

Through something that is called photocatalytic action, when exposed to sunlight, this coating actually breaks down organic dirt. The UV rays from the sun cause this reaction. It usually takes place within a week of installing the glass.

The second thing this coating does is to make water spread out as a sheet on the surface of the glass instead of forming water droplets. This sheet of water washes down the glass and cleans it naturally. This stage is called the hydrophilic stage.

Knowing how Pilkington K and other self cleaning glasses work does not answer the original question, though. Whether they makes ordinary glass cleaners go out of business or not is something that remains to be seen. Self cleaning glass has, however, become widely used in the construction of conservatories and other large, predominantly glass structures and are a big reason why they have become so popular.

Of course, this glass is more expensive than normal window glass, but many homeowners and businesses have found that it is more than worth the extra expense. Only time will tell if it replaces normal glass completely, though.
