Re: Re: Irish say no to PVC windows

Yes – the OPW used it in the restoration of the glasshouses in the Botanic Gardens. It is laser treated, generating wavy patterns. Presumably you can get it to mimic a variety of effects, from crown to cylinder, to early 20th century artifacts.
Presumably it is also very expensive 🙂

There’s a few companies that still make glass using the old, or at least similar methods to produce the same results. You should be able to find some internet sites with more.
