These sustainable, high-performance insulation products are constructed with thermally efficient polyisocyanurate (polyiso) cores and engineered for long-term R-value retention. Energy Board II and III are available with durable facers that enhance dimensional stability, moisture resistance, and surface strength—making them ideal for direct membrane attachment or use beneath coverboards. By combining high thermal performance with sustainability benefits, these boards contribute to energy-efficient roofing assemblies that support long-term building performance.
