crispy_wafer Posted February 6, 2021 Share Posted February 6, 2021 Having a discussion with a builder about our cavity wall insulation, he's recommending isover 32, and I'm looking a dritherm 32 as that appears to be a well used, and recommended cavity batt on this forum. I've looked briefly at the spec's and to my untrained eye they look identical. Only the price of the Isover stuff seems to be that much greater, so I'm thinking I must be missing something. I'm using insulationshop.co as my reference but other retailers have similar price difference. If I can save a few pounds here and there then I'm all for it. What say the buildhub experts?

Moonshine Posted February 6, 2021 Share Posted February 6, 2021 (edited) Interested in this, what is better / easier to install, glass or mineral? Doesn't glass irritate / scratch the skin, or do both? Edited February 6, 2021 by Moonshine Link to comment Share on other sites More sharing options...
