ASTM C1289 Compliance

Polyisocyanurate, or PIR, is a high-performance rigid foam insulation known for its superior thermal efficiency and enhanced fire resistance compared to PUR. Its closed-cell structure minimizes heat loss and heat gain while providing excellent moisture resistance and long-term stability.

PIR is lightweight, durable, and available in boards, pipe sections, and panels, making it ideal for pipelines, tanks, HVAC systems, and building applications.

Widely used in oil and gas, power, cold storage, and construction projects, PIR delivers reliable insulation where higher safety and energy efficiency standards are required.
