New Build regs on insulation

[Bellendian]

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.

…...…..The contracts manager says it's fine. He said its some special insulation.....

And his professional competence and qualification to make that statement is ?????
