Given that aerated concrete blocks have thermal insulation value of between 1/2 and 1/5 of 100mm rockwool should a cable chased into the wall and skimmed over with plaster be down rated as per installation method 100 or 102 ? Is this altered if the cavity behind the aerated blocks are filled with 50mm polybead insulation?
