We know many of you have been eagerly awaiting TimberBoard’s arrival. The wait is finally over — and it was worth it. Our TimberBoard line is now rolling at our Madison, Maine facility, producing the first wood fiber continuous insulation of its kind made and sold in the U.S. This milestone has been years in the making, and we couldn’t be more proud to bring this high-performance, sustainable solution to the market.
Certification in Progress
Because there’s no precedent for a product like TimberBoard in North America, we’re now entering a rigorous testing and certification phase with the International Code Council (ICC). Earlier this year, ICC published the acceptance criteria that will guide this process, setting the stage for TimberBoard’s full market entry.
The first product in the line is a 4′ x 8′ square-edge sheet, available in multiple thicknesses. Though untreated, its density offers inherent flame resistance, earning it a Class B rating under ASTM E84.
Why TimberBoard Matters
TimberBoard isn’t just another insulation product — it’s a breakthrough for the U.S. building industry. Made from abundant renewable wood residuals, TimberBoard is a carbon-storing insulation that helps turn buildings into long-term carbon sinks. It delivers the durability and compressive strength of rigid foam or mineral wool while remaining vapor-open, allowing assemblies to manage moisture safely and naturally.
TimberBoard Highlights
- Thicknesses ranging from 1” to 9.25”
- Vapor-open continuous exterior insulation with high compressive strength
- Price competitive with rigid foam and mineral wool
