A built-in foam core gives the R.20 Tstud™ almost three times the insulation of a conventional wood 2x6 stud.

In construction, the R-Value is the measurement of a material's capacity to resist heat flow from one side to the other. In simple terms, R-Values measure the effectiveness of insulation and the higher number, represents more effective insulation. The R-Value through a typical 2x6 wood stud is 6.88. Any wood member causes there to be a transfer of heat and cold from the exterior of a home or a building to the inside of the same space; known as conduction. The only way to stop, or minimize, the transfer of heat or cold from one side of a wall to the other side, is to purchase and install thick enough rigid insulation to the entire exterior perimeter of the structure.

The R.20 Tstud™ is the same depth as a 2x6 but offers an impressive initial R-Value of 20 and has a 99.23% complete thermal break through the stud. Meaning that there is no need for continuous rigid insulation to meet and exceed the 2015 energy code in all of the climate zones in North America.


The proprietary truss system that holds the 2 wood members together accounts for .77% of a thermal transfer of heat and/or cold.

The truss is non-metal and is fully encased in Type 1 foam (an HFO blowing agent that is 2020 EPA compliant is used).

By using the thermally broken R.20 Tstud™ Wall Assembly, a reduction of 4-7 points on the HERs numbering system is garnered yielding the building an approximate 18% improvement (depending on heating or cooling degree days, the climate zone energy code currently in force, and how many times the dog is let out the door) in energy efficiency over standard 2”x 6” wall construction. The R.20 Tstud™ will be an excellent LEED (leadership in energy and environmental design) product.

This increase in the R factor is significant as there is not another solution that acts alone to offer as aggressive of an outcome. 

Therefore, with incentives to both builders and consumers being offered by way of rebates through government and utility providers, there is an opportunity to drive change to build with more energy efficient components to meet the new rigorous energy code legislations and net zero effect initiatives.

A test was performed by placing a commercial grade hot iron on one of the wood members. That wood member was heated up to 194 degrees in an effort to see how fast that temperature would conduct through the wood, through the foam, and increase the temp on the opposing wood member in order to replicate a wall comparable to one in San Antonio, Texas.  After 1.5 hours, the temperature of the opposing wood member rose by only 3 degrees. Proving, that the R.20 Tstud™, has a significant benefit in southern cooling zones and in northern heating zones.
