For example those for the current project come in at 1.1, with the Saint-Gobain spec: 22.1 (14 Argon 90) 42.1 ECLAZ F3. Going to triple glazing wouldn't have made a big difference by itself; for that I'd have had to upgrade the frames to PassivHaus standard. I'd like to have done that, but the profiles are non-standard and the upgrade couldn't be justified financially.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17975&Focus=303894#Comment_303894 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17975&Focus=303894#Comment_303894 Wed, 18 Oct 2023 00:49:15 +0100 Mike1
