My loft was insulated by a company nominated by my gas supplier and they sprayed Rockwool to the required depth. They have put signs up there saying not to walk on the stuff but how do professional electricians navigate their way through this material? There are only lighting cables up there but I can see a time in the future when I might need to replace a fitting or two or even have a re-wire. Just curious really. I did take photos before the work was done so that might help, I suppose.
Access to fittings in Rockwool insulated loft?

Its a right pain
You have to feel carefully where the joist is with your feet to know where to stand, or in the cases where its rolled rather than sprayed, to shift the parpedicular one on the main walkway out the way so joists can be seen.
To find where the cables drop to the fittings takes a mixture of guessing where it is, and just digging through the damn stuff until you find it.
Its when the lighting is looped in at joint boxes under the insulation, branches go off everywhere and theres a fault that keeps the RCD tripping out that it gets to be a right pain, you don't know where the joint boxes are, so you have to follow a cable, find a joint box (hopefully aiming for somewhere in the middle of the circuit), separate the cables, test them to find which one is down, put it back together and follow that cable, and keep repeating!!
Lighting cables are ok under the insulaion because they are underloaded in a domestic, however any other services must not be under the insulation, although those who fit the insulation don't seem to care!
