Concrete SIPs and Air-Sealing
I’ve been a long time lurker here. Thank you all for all the information that you share in these forums. There is so much to learn and I’m indebted to all your work.
We are building a home in Santa Clara County CA (Climate Zone 3C). I have decided to use concrete SIPs (e.g RSG 3D, Innstruct) to build our house. This is basically an EPS foam block covered on both sides by concrete. The goal is to add additional fire resistance to the building, but I also want to use this opportunity to build a passive, air tight, energy efficient home. I hope that I can connect with other folks here who might have used this building system.
This video provides a good description of this system for folks who might be unfamiliar with it. https://www.youtube.com/watch?v=ffpheVop4RI
Coming to my question: (first of many, I expect)
This will be a slab on grade foundation. What is the best way to ensure a very good seal between the flooring and the walls. I was thinking that we might employ a tape of some sort which can stick to the concrete on the floor level and the steel cage on the wall before the shotcrete is applied. However this does not seem very clean or elegant. Any other experiences or ideas?
