Afternoon all,
I'm at the stage of insulating between the floor joists above the garage to the bedroom above. I've got quite a lot of spare PIR board that I'd like to use for the area at the very front of the garage where it seems coldest.
Does the celotex go tight up against the chipboard flooring above to leave a void below? Or does it sit flush with the bottom of the rafters? Thinking it should sit tight to the floor above but would like a nod from someone in the know.
The rest of the joists with cables and pipes running through will have the itchy insulation placed between.
Can someone advise?
Thanks
