but seriously. need help with figuring out what to put in that ceiling cavity now (links would be great). all the joists in the house are on 37cm spacing (but a very sloppy 37cm spacing at that). so i'm going to be cutting a lot of insulation no matter what type I use. I didnt get round to measuring how deep the space is up there yet either.
That’s a hard weekend. Really good job though. I’d use something hard like kingspan/celotex not a soft roll of rockwool or whatever. I think it is more expensive but it’s easier to deal with, easier to cut, and you can probably use all the spare offcuts still.
