Hey guys, looking at putting UFH in our extension that we are hopefully getting built next year. The plans show block and beam, then insulation, then a 500g polythene protection layer, Then I’d put the UFH in followed by the liquid screen.
My question is regarding the clips piercing the polythene protection/vapour layer. Is my only option to use the egg Crate system?

Could I not fit a second layer of vapour barrier?
