Thought folks might be interested in this new (to me) product from SIS panels called “Studulate”

What would you expect the sheathing nailing requirement generally to be? To go through the 2" of foam and yet create racking strength would that require a 4" nail (1.5" embedment)?
I think 3.5" according to Warmstud product test report
I could only see either product being used in modular construction.
First, thermal bridging is a smaller problem than a lot of people realize, and it can be addressed in a number of ways. More important, in on-site construction sequencing is critical. Everything else runs off of the framing. To replace something as ubiquitous as the 2x4's or 2x6's in exterior walls with a product that might have to be special-ordered is an enormous risk. It often happens that for whatever reason the framing takes more lumber than anticipated and the framing contractor has to run out to a lumberyard or big box store and get a few more pieces. If you were using insulated studs and that happened there would be enormous temptation just to replace them with regular studs to keep the project moving.
DC,
That's much how I evaluate any new product. That it is a good idea is only the first hurdle. Until I see widespread adoption and availability I can't get too interested.
Although, to be fair the same argument could have been made against almost any engineered wood product when it was first introduced, like I-joists or trusses.
DC,
Yes, and until they started stocking I-joists in my lumberyard I didn't use them. Hats off to the early adapters who help the products spread, but I don't want to be the one left with a mini-split you can't get service or parts for, or pausing the framing while more specialty products are freighted in.
At least in this case it seems like you could site-build your own in a pinch - rip some insulation panels down and glue them on.
Though that raises the question of why the need for a specialized product at all. Just get some poor apprentice to make an equivalent. I guess ultimately it will come down to relative cost and impacts on project timelines.
If it's a structural wall, if it's not a prescriptive design it needs an engineer's stamp. If the engineer called for a specific product it needs to be that product.
Thanks for sharing, I'm part of the SIS Panels team developing Studulate. Let me know if anyone has any questions.
We are developing and testing Studulate as time permits, our insulated sheathing is our priority. Once our current round of testing ends, we will revisit Studulate to better look into effective R-Values and other critical information.
Hi Peter!
You make some great products!
