New house build, SIPs?
New member here, we are planning to build a new house this summer and I’m exploring my options for wall systems. I plan to do the framing myself. House will be roughly 2500 sqft in Ottawa, Ontario Canada. Not the coldest place to build but not far off, and just for kicks it gets pretty hot and fairly humid here in summer as well.
I’m weighing my options as far as wall construction goes. I would like to build as much insulation into my walls and ceiling as is practical, targeting a cavity value of around R40 seems like a good goal, and a reasonable effort to minimize thermal bridging for good whole wall performance.
I’ve been thinking about a double stud wall and was leaning that way fairly strongly until I came across Raycore SIPs. I like the idea of having studs, and they make a version of their 5.5″ wall with offset 2×4 studs which should help significantly with the thermal bridging issue.
My question to the experts here: is this Raycore system worthy of a truly efficient build? Has anyone here used this system before? Are there other similar systems available?
My searching hasn’t turned up anything else besides the typical OSB/foam “sandwich” type panels, and I’m not sure I’d want to trust the OSB-to-foam bond for structural walls.
Thoughts? Looking for all the input I can get. The double-stud approach would likely be cheaper, but I will be doing this myself so simplified construction will be worth something as well. Thanks!
