How can you tell if double glazing is pre 2002 or post 2002
Er, not quite. The window has to conform to the Building Regulations but Fensa, a trade organization, is just one way of getting a certificate to demonste compliance. Getting a certificate from your Local Authority's Building Control is another way.philipdayton said:and the product must be Fensa registered.
Pilkington K is just about visible in certain lighting conditions, as you describe, but Optitherm and other soft coats (which give a lower U-value) are pretty much invisible. There is an electronic detector that can identify whether a coating is present.philipdayton said:You may be able to tell with certain glass coatings if you look closely at an angle to the glass, if it appears to have a coating chances are they were fitted after 2002.
