Exterior Pipe Insulation

[pat5627]

I need to insulate 40metres of 22mm Hep2o pipe buried approx 400ml deep. I have been advised to use Armaflex Solar Insulation pipe is there any other product that will not deterioate in the ground but costs less than the Armaflex?

Hmm Hep2o underground...that's a novel idea. If you bury it deeper I wouldn't have thought you'd need insulation at all - take it down to about a metre and it shouldn't freeze or warm up much. In other words, get your spade out and you'll have free natural insulation...

But use mdpe for buried mains rather than hep

But the op is burying it 400ml (=miles) deep anyway.
