Hi all.
I am required to do a complete rewire on a 1920s terrace property with 9" solid brick walls which is then to be replastered using 30mm wallboards dot and dabbed to the brick- that is 18mm insulation backed onto a 12mm plasterboard.
Sure many of you have done this many times so my question may have an easy answer.
Do I surface mount the cables to the brick cutting the insulation off of the board in a channel around the cables and call it clipped direct? Don't really want to be uprating cable sizes and then derating them for insulation!
Obviously there is a direct conflict between keeping the walls warm and the cables cool!
Any advice would be appreciated immensely as the reference methods in the regs do not appear to cover this situation definitively.
Many thanks in advance
