We had some doule glazing installed earlier in the year as part of an
extension and I've just realised that we didn't get any documentation.
Should we have had anything? (FENSA certificate, etc?)

Aren't the dg panels etched with the relevant BS ?

How does that prove that the windows were installed by a FENSA approved
fitter?

Anyone can get the panels with the right BS numbers.
