Why PowerWool for Your Next Build
1. High Compression Strength
PowerWool RigiBoard 80 is rated at 616 psf at 10% deformation (ASTM C165). Fasteners and furring strips seat firmly without crushing the board.
2. Exceptional R-Value (R‑4.2/inch)
Need to meet British Columbia’s Energy Step Code or stringent US/Canadian energy codes? PowerWool RigiBoard 80 delivers high thermal performance at R‑4.2 per inch, ensuring your building envelope meets modern insulation standards for energy efficiency.
3. Highly Vapor Permeable
PowerWool’s rigid mineral wool design is more permeable than many “breathable” housewraps, allowing trapped moisture vapor to escape easily. This advanced drying potential helps reduce the risk of mold and water damage in your exterior wall assembly.
4. CCMC-Approved & Code-Compliant
As a CCMC-approved product, PowerWool RigiBoard 80 is well-suited for applications where rigid mineral wool insulation products are applied. It’s noncombustible (FSI 0, SDI 0) and designed to enhance fire resistance in exterior walls.
