Achieve Better Thermal Resistance
With The Most Advanced Wall Sheathing

Better Thermal Resistance Board (BTRboard) is an insulated wall sheathing product combining OSB or drywall with low-absorption foam in one product, eliminating extra layers and streamlining construction.

Substrate Layer

1. Inert Fiberglass Facer

  • Increases structural strength
  • Mold, moisture and fire resistant
  • Limits foam shrinkage & increases shear strength

2. Cross-Linked Medium Density Polyiso Foam

  • Moisture, fire & chemical resistant
  • High dimensional stability
  • Strong compressive strength (20 PSI)
  • 14% bio-based content
  • 70% better R-value than similar EPS Panels

3. Substrate Layer (material varies per application)

  • Rigid substrate works as nailing surface

Wall Construction Comparison

BTRboard enables builders to achieve code-compliant effective R-values using 2×4 construction, or exceed it with standard 2×6 construction. A BTRboard wall with 2x4s at 16″ o.c. and R-12 batts delivers an effective R Value of 17.4; meaning less lumber, less insulation, and a simpler assembly.
