T-Stud Framing, is it the Future?

Why not use a 2x6 plate and then use 2x4's staggered on 24"OC. You then have a wall that is essentially framed at 12" OC. I would bet that would be alot less than the TStud, and is also very friendly to plumbers and electricians.

it always astonishes me how little value is placed in the USA on the strength in walls. The second point is, I would never use an isolation that burns, or even produces poisonous gases while burning or melting. For me I would use 2x8 for strength. On two storey houses, the 2x8 go all the way, not ending below the second floor, with a second set above. Isolation would be stone wool. When you need additional Isolation or protection against fire you place a 50 mm continuous dense (heavy) stone wool cover on the outside wall.
