Vapour barrier

Now we are finishing up all the vapour barriers. We are using  CertainTeed MemBrain which adapt its permeability depending on the climatic conditions. This is to avoid trapped moisture inside the wall which can happen if you use traditional 6 mil polyethylene vapour barrier.

Around all the electrical openings, we taped up carefully so that there’s no direct openings.

And as you can see we’ve used black acoustic caulking to bound the sheet to the stud walls.

This is the work in progress on the second floor.
