Hey !
So UFH installer has taken a look .
He wants 150mm pir on floor then vapour barrier before they put ufh pipes followed by screed .
What type of vapour barrier should I use ? . I assume I tape any joints ( with what ? ) . I assume I run it up the timber frame studs so screed doesn’t touch studs and also to stop screed going under ufh .
Any advice welcome! ?
