Untreated wooden windows – do such windows exist?
Can anyone tell me if untreated wood windows exist. I seem to remember hearing that before, but I can't find anything like that now.
Since wood windows cannot be left untreated, the profiles are usually treated (such as with pressure impregnation) during production. So you would have to go to a supplier who also manufactures windows specifically for heritage sites.
But all in all, I doubt you'll find what you're looking for in the industrial window market.
