For sale at the end of an install I have 11m of premium UF heating barrier pipe. It is aluminium lined so holds its shape when installing or bending it. Also there are x14 of the 1m clip rails. They can be nailed or screwed in, or use the adhesive tape to stick them down. Works brilliantly, see picture of my install to see how it works. I can deliver to Aylesbury and surrounding areas for a small fee, or collect from Quainton, HP22. Any questions please ask, happy to help :)
