This is a blog about building a more sustainable lifestyle in Newfoundland. We built the Flatrock Passive House in Flatrock, Newfoundland. As it stands, this is first performance house built to the PHIUS standard in Newfoundland. Construction is complete but the project is still moving forward. We are currently exploring and devising options that deal with food security. We recently completed a vegetable garden and root cellar and are currently working on a winter greenhouse!
Lets Try This Again: A Well Insulated Slab
Time was ticking and we ran out of 2" type II EPS. Luckily our local building suppliers carry a small supply of 2" 2'x8' Foundation Plus. The next morning we finished up placing the foam. Pipe and conduit penetrations in the foam were cut slightly oversized to allow some room for aligning the foam pieces together. After the foam was laid, we spray foamed around the pipes (Photo 1-1). This serves 2 purposes: The first is to insulate, the second is to stabilize the pipes during the cement pour.
On to the next task: Vapour barrier, air sealing, and rebar!
