We are renovating a house built in 1911. We have taken down a lath & plaster ceiling (before it fell down), I have also removed lath & plaster from a partion wall as it was blown. Anyway the dirty deed has been done : )
I now want to insulate for heat and noise. I am going to hang a floating ceiling with resilient bars and want to insulate above them. The ceiling light cable is notched into the top of one joist, and then is through a drilled hole in the joist to the light fitting. How much clearance do i need to leave between Rockwool insulation and cables so they dont become a fire risk?
I have the same question for the walls - whats the safest way to place the insulation - do I leave the bits with cables in empty (even though this would defeat the object). The ceiling will have a small cavity for cable to sit in, but the walls will have no cavity as space is a bit tight.
Would appreciate some advice of any one who knows.
Thanks in advance
