Discuss New Build regs on insulation in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net

Most timber frames I've been involved with have insulation placed within the wall units, vapour barrier in front of insulation, and then 32mm counter battens to create service void and provide a fixing for plasterboard. In this scenario no cables are running within insulation itself and I wouldn't have any concerns over a 2.5mm ring on 32a breaker.
