I have been told that Pilkington Activ can be easily scratched and should this happen the whole unit needs to be replaced. Is this true?
Suppliers that do not offer Pilkington Activ are often quick to dismiss the benefits of such a revolution in glass. The Pilkington Activ coating is applied as the glass is cooling down in the float process and is what is known as a Pyrolitic or hard coat. This happens at around 600 degrees C.
