Hi,
I have a loft that is currently unboarded. The roof has been sprayed with a yellow 'foam' all over which I'm presuming acts as insulation - or is it designed to keep the roof in one piece??? Its 50's house so this could be the case.
If it is there for insulation, should I also add insultion between the joists (and how thick) before I board the loft with chip board? The more the merrier right? or is mixing the two types a bad idea?
Thanks!!
