Hello,

I want to insulate hot water tubes (multilayer) passing through the ground, under the slab.

What is the best solution?

please

under the slab it is not easy, in any case you pass it through a sheath.
I would say to you, from the outside to the inside.
geotextile felt, plastic film, rock wool, sheath, PER.

Hello,

The simplest (but not the cheapest) is to use polyethylene sleeves.

slut, stupid question but the slab is already there ???

Otherwise the PER is not expensive compared to copper but it is beautiful ME ... of, this being why not the insulation for foam rubber pipes ???
