Russell griffiths Posted November 2, 2023 Share Posted November 2, 2023 Your vapour control layer on the ceiling needs to come down the wall and be taped onto the wall, then whatever method of air sealing you are doing for the walls gets lapped either over or under that, if you are dot and dabbing you dab over the ceiling membrane. Just imagine you need to draw a continuous line inside your house with no breaks in it. Link to comment Share on other sites More sharing options...
