Could someone help solve an argument.
What is the correct sized lagging used after installing underfloor 15mm and 22mm copper pipe on the flow and return heating pipework?
Is it 9mm for both?
Also what is considered the best method of securing underfloor copper pipes?
My view is that, all underfloor copper pipework should be secured and lagged by using plastic pipe clips and secured with plastic ties to the lagging. Whilst others think using galvanised metal straps to secure pipework is ok on top of the lagging?
I have always been shown that plastic pipe clips should always be used?
Thanks
