Well, i’ll take a steer when we get a quote but from what i have read you seal around the edge of each board/join both with tape and a continuous bead of adhesive. i presume it’s different depending on your wall being solid or cavity and if you have a membrane as part of the board(or not) but would obviously want to avoid interstitial condensation.
would remove skirtings and go right up to the slabs.
Mr_Smyth
Unsolicited questions instead of answering your question. But. Isn't dot and dab insulation going to cause condensation/damp issues? Unless your vapour barrier line is 100%. Wouldn't a build-up with no cavity/void be better?
