Housewrap

According to the manufacturer of the wood fibre sheathing, the boards could act as a wind and waterproof layer. But a couple of issues made me question that idea. First of all, I wondered how I could make the connection between the sheathing and the windows. I asked for a tape that would stick to the sheathing, but the building supplier couldn't find me one. Also, because I made lots of cuts into the sheathing in order for it to go around the curve, it was definitely not meeting the manufacturer's specifications for wind and water tightness.

So, I decided to play it safe and install a housewrap-type membrane. It's pretty straightforward to install- roll it out over the roof and walls, staple sparingly, and tape the joints. There was just a bit of complicated tapework to make it go around the curves.
