Hi, hope someone can give some advice on insulation for radiator pipes that are outside the insulated space in the house.
We are having an extension and the first fix has just put radiator pipes in the loft space and the 'cold' vented part of the roof (the wrong side of the 170mm of pir we have to have) so pretty much classed as outside. I can see why it was done to avoid pipe routing on show but now I don't know how this is supposed to be insulated to meet current standards. Our plumber doesn't seem to think there is an issue but I can't see how it is doing anything but throwing heat away and maybe at slight risk of freezing. Any suggestions on what is normally done please?
