Thanks for your input but i will need to show which insulation types and cost and finally calculations Mr, Russ. i will need to prove how i got the 60mm....i Know for a professional like you its just straightforward wen you see the problem but for a novice on such its confusing...i have read and done a few calculation on heat transfer via thin walled, critical radius probem n thick cylinders but this one is beyond my head
