Wall Cavity Wiring.

Good morning on this bright and sunny start,


                          Q. Which regulation(s) specifically prohibit(s) the installation of cables in brick and block cavity walls within the cavity?


in a, Older premises?


    b, Newer premises?


If regulations exist, what reasons are provided for the prohibition? Or are we just concerned about chemical damage of cable insulation if the cables are in contact with some types thermal insulation?

  • Where is all of this water coming from Andy?



    Rain - penetrating the outer leaf - as most masonry materials aren't completely water tight. Breaking that path was the original purpose for having a cavity in a cavity wall after all. Try some building text books or the building regs.
