[QUOTE="OnOff, post: 372556, member: 16173"] Cheers. Daft question...........say the new Celotex sits atop the joists. I was thinking 150mm thickness. (I understand the comment ref insulating at the edges btw). To achieve the "seal" do I foil tape down the 150mm edge and onto the side of the joist? Ta. [U]EDIT[/U]: Just worked out how to add BIGGER photos from [B][I]Flickr[/I][/B] so have edited the OP. You might note some T&E clipped to the upstairs dormer floor joists - just visible behind the nasty pipework. I did that wiring, Then ripped up the old flat roof and found "spaghetti" white T&E & JBs you see just "hung" at the mo pending being ripped out. [/QUOTE]
