Insulating around radiator pipes and junction boxes?
I have 1920's house with a suspended timber floor. I was thinking of adding Kingspan/Celotex 100mm insulation in between the joists. However, I have electrical junction boxes attached to the joists and also pipework going through and above the joist in a few places. What's general consensus around installing insulation around the electrical junction boxes and heating pipe in regards to fire safety. Any pointers would be hugely appreciated?

Would cost from £300 to 600
Hi guys,when we carry out loft works we come across this issue sometimes we leave a gap around the boxes as I never like to insulate to close juts for safety reasons but there is now a more eco friendly product on the market and it’s strictly fire proof it’s perfect for round these points and closes any cold air spots
100mm distance as per building regulations
Yes however would recommend using pipe insulation and make sure it’s down correctly along with insulation that gets put down to avoid any risk of fire
