Re the previous poster and insulating plastic pipes. Pretty much all of my pipes are insulated but have a few feet in the garage where the combi boiler is now located, the garage also has a radiator which stopes any freezing or dampness. I realised I have loads of bubble wrap so thought to try and use that for insulating the few pieces of pipe in the garage, and in warmer weather will check under the ground floor.
I read on google about using a layer of foil plus the bubble wrap but was wondering if there should be an air gap between the insulation and the pipe, or between the bubble and the foil? I am just wondering the best way to construct this using the bubble wrap.
Any ideas or suggestions?
