Progressive Engineering, Inc of Goshen, Indiana, has tested a prototype of the Tstud™ vs a traditional 2x6 used in framing of an exterior wall. The tests were performed for a length of 10’-0” in straight down vertical compression to see how much a single stud could hold before failure vs a Tstud™ of a similar length. A #2 select 2x6 held 4,300 pounds on average while the Tstud™ held an astounding 12,655 pounds.

All dimensional lumber, that is used in exterior wall construction, fails testing on the “x” axis (the 1-1/2” direction) as more weight is applied. Because the Tstud™ has been designed to stop deflection on the “x” axis and the “y” axis, the only way for the Tstud™ to fail is from straight down compression of fiber upon fiber. Thus maximizing the strength of the Tstud™ as a engineered structural wood member. All testing has been completed at 24” on center framing spacing - proving that all exterior walls can be constructed with superior structural capacity and at that spacing. Saving builders thousands of dollars in labor, lumber, nails, staples, and screws, from using 20% less framing members needed to construct a wall. Of course, a builder can also use the Tstud™ at the standard 16” or 19 diamond spacing.

Due to the construction of the Tstud™, it is also a mini header when used as a top plate. Only one Tstud™ is required when used as a top plate compared to two 2x6’s or 2x4’s in traditional framing which has been done for centuries. 

Because of the testing capacity of the Tstud™ in the plank direction, as in headers and top plates, less lumber is required to be used - again saving builders time and money!

The Tstud™ is potentially stronger than LSL (laminated strand lumber) or LVL (laminated veneer lumber) stud sized lumber in most applications up to 16’-0” in height. See the wind load tables in the technical evaluation report (TER and compare to LSL and LVL studs without lateral bracing). The Tstud™ is able to be used in walls up to 16’ in height. Up to 32’ with additional testing.
