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?

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
