Another part of the membrane project started in May was finished today. Mostly through the inspiration of our friends Jan and Mike Halla who visited last week. They said, what can we do to help? Mind you they were only visiting a day and a night and a morning. But not only did we get the tub in the house, we also put up membrane in the room I had prepared way back in early summer. I remember it being hot up there near the ceiling though and the weather is now a bit more cooperative.
Help with the membrane
Jan got the idea to put the wide section at the bottom so that the angled ceiling could be cut from a smaller piece and would be easier to handle. Good call; extra brains as well as extra hands. The double sided tape is covered with paper that is pulled away as the membrane is pressed up to the ceiling.

Inspiration started, I was able to finish in a few more days. The overlapped areas were taped with the special SIGA tape that is pretty easy to work with. Paper is pulled from the back and then as it is pressed against the seam all along the opening.
Ceiling Layers Taped
After taping the edges are caulked to the top of the wall with SIGA caulk. The caulk is visible in this detail picture of the tape around the plumbing vent pipe.

The caulk can’t take any pulling from the membrane so in some places like this corner, it was necessary to push the membrane against the caulk until it dried enough to hold.

The next step is using the repurposed boards taken from free pallets to put up the furring strips to hang drywall from. Dave will probably get that done next week.

We still have the flat ceilings to do and the hallway to the bedrooms which is a continuation of the master bedroom roof slope. In some spots we have to wait for the wiring to be finished before we can finish the ceiling membrane but the outside walls also will need to be covered with the membrane. We are eliminating most of the outside wall outlets to minimize wiring penetrations through the air barrier. It is great to see progress inside again thanks to our visitors!
