ISO-HT® is Kingspan Insulation's 2.5 lb/ft³ polyisocyanurate rigid, closed cell, foam insulation for higher temperature applications up to 350°F (177°C), with intermittent exposure up to 375°F (190°C). ISO-HT is suitable for constant temperature or heat cycling environments. ISO-HT is certified by independent laboratory to meet demanding Class 1 flame spread and smoke development requirements per ASTM E84. Kingspan offers ISO-HT as bunstock or as sheets and blocks, with tolerances up to 1/32 inch on surfaces. Our extensive network of fabricators can provide special shapes for pipe, fittings, vessels, or other mechanical applications.
Polyisocyanurate exhibits the highest R-factor (insulating value) to thickness ratio of commercially available insulation. Ideal for applications over a wide range of temperature, from cryogenic liquids to low-temperature steam, hot water, and process applications. ISO-HT offers superior performance when compared to fiberglass, mineral wool, polystyrene, polyurethane, fiberglass, and cellular glass alternatives.
