In this walkthrough, we highlight key design ideas and how they translate to performance for high-temperature PIR foam board insulation. You'll see how the isocyanurate structure supports service temperatures up to +150°C, how low thermal conductivity around 0.023 W/(m*K) helps reduce heat loss on pipes and vessels, and how the B1 fire rating and closed-cell structure contribute to moisture resistance and safer industrial insulation. We also demonstrate typical applications including heat pipes, flue and duct insulation, solar hot water systems, and process equipment, so you can evaluate whether this solution fits your plant requirements.
