This is a 200yr old farm cottage - stone built and with probably excessive under floor ventilation, which is being looked at as another project.
But - the electric meter is mounted externally in a box set into what was originally a small window, and the CU inside in the 'window' cavity. There is insulation between the stone walls and the plasterboard throughout the house except at his point, and there is a fairly hefty flow of cold air goes up passed the CU.
In order to make wiring access easy, the inside wall facing at this point is a top and bottom 3/8" ply panel (18" wide) and a hinged access door to get at the CU. None of these have any insulation so are cold spots.
I rescued some Kingspan from a skip the other day with one of its uses being to address this.
The question is this - some dozen cables go upwards to the attic from the CU; should I bundle these loosely and create a slot in the insulation for them or just leave then sandwiched between the insulation and the stonework - the distance is about 18" ?
Many thanks Rob
