Essentially they're a truss.  2x3 caps with dowels.  Then the gap is filled with foam.

They're CLAIMING R20 for a 2x6 replacement and R32 for a 2x8 replacement.
They also apparently sell foam-free studs if you're going to spray-foam your home anyhow.
Frame, run wiring, plumbing, etc.  Foam it all in.  Looks like the unit strength of such a wall would be impressive.
Also, these can be used to build insulated headers for doors and windows too.

No, it's not ICF or SIPs.  But it DOES look like an interesting alternative.

Very cool....thanks for sharing...

No problem. You stumble across interesting stuff in weirdest places.

I haven’t seen that variant, but have I seen similar built on site for likely less cost. Just two 2x4 studs spaced 8.5” apart using a couple 2x4 blocks. Walls are foamed 3” deep and R19 batts are used. 2x12” are used for the sill plates. It all comes down to how much R-value is appropriate for the local climate and the cost of getting it... Having a 3.5” wide stud is a nice feature.

I like the features of the T-studs and hope that they will be available at local lumber yards soon. Otherwise, most builders will not be aware of T-studs.

Talk with your local lumber yards about becoming distributors.
