A reduction of up to ~20% of heating and/or cooling bills for the life of the building has been calculated based on initial third-party analysis and based on Fourier’s Law of Conduction.  The Tstud™ means approximately 24% of an exterior wall is 290% more energy efficient compared to standard 2×6 lumber studs. The average payback in North America is estimated at 2-6 years based on Fourier’s Law calculations (dependent on average temperature of location), the reduction in heating and cooling bills lasts the lifetime of the structure. Thermal imaging of a shed constructed with Tstud™ walls, floor and roof, shows heat loss only through the door. The built-in foam core gives the Tstud™ three times the energy efficiency compared to a conventional wooden stud.

1. 4” of closed cell spray foam = R26 and no OSB. Add an R11 fiberglass batt in front to get to an R36+

2. Lay down a layer of water resistive barrier (WRB) that is required on every build in North America on a table first,

3. Build the wall panel on top the WRB, builders’ choice of 16” or 24” on center framing,

4. Leave the WRB hang down long enough to overlap the rim for ease of solving for taping in the field,

5. Spray 4” of closed cell spray foam the 5-1/2” or 6” in a 7-1/4” BareNaked Tstud™ frame,

6. Pre drill holes for the electrician,

7. Stand up the wall and attached rain barrier strips so the builder does not have to do this in the field,

8. Have no panel weigh over 200# so a crane is not needed on the job,

9. When the panel arrives at the job site, the builder can add in an R11 fiberglass batt in front or a blown in cellulose or fiberglass to get to an R37
