I'm putting the insulation in for my loft conversion and not sure how to put the Celotex around the pipes and electrics.
I've had first fix plumbing done as shown in pics. Tried Googling and searching this forum but all answers were for wool insulation, not PIR.
What's standard practice here? Do I cut two seperate pieces of Celotex for each section - one to put above the pipes and one to put below? Would some rockwool then be required behind the pipes?
OR do I just one piece of Celotex for each section, and notch in a gap with a stanley knife for the pipes to run through it?
Also wondering the same for the 1.5mm lighting cable and 2.5mm power cables. Is conduit/trunking required for these?
