Thermatech panels are for the exterior walls. The package combines exterior framing and insulation before delivery, plus all coordinated dry-in materials. For the interior, choose full-length lumber bunks or preframed walls in REZ Wood or typical lumber.

Explore Thermatech ↗

High-efficiency note: A June 2026 third-party thermal model says a conventional wall would need roughly R-42 to R-43 in wood framing or R-49 to R-50 in steel framing to compare with the modeled Thermatech system. The Thermatech assemblies themselves modeled at approximately R-20.5 to R-21.1; the higher numbers are comparative equivalents that include assumed air-leakage improvement, not directly tested Thermatech insulation ratings.

What's included

  • Preinsulated Thermatech exterior wall panels only
  • Interior framing options: lumber bunks or preframed walls in REZ Wood or typical lumber
  • Precut exterior window and door openings
  • Windows
  • Exterior doors
  • Siding supplied for field cutting onsite
  • Roofing supplied for field cutting onsite
  • Radiant-barrier roof sheathing
  • Engineered trusses or reviewed conventional roof-framing lumber bunks
  • Weather-resistive barrier where required by the selected wall assembly
  • Fascia
  • Soffit
  • Exterior trim
