With the roof finished, our crew moved on to the task of siding the project. Our initial plans called for a rain screen, but (for many reasons) we decided to forgo this measure. Instead, we opted for several layers of weather resistance including Tyvek and XPS (pink foam).
Working outward from the plywood siding, the wall is composed of:
- A Layer of Tyvek ship-lapped over the lower layers of pink foam board
- 1″ layer of pink board to mitigate thermal bridging (click the link for more details)
- 1/4″ Hardi-board (cement-fiber board)
My contractor, Rory Read, has an excellent article discussing the pros and cons of this wall system. He also details the thinking behind each decision point – it’s an excellent read.
Here’s a time lapse video of the Tyvek installation, followed by a video of the siding on the building’s north face.
