ISO-C1® Polyisocyanurate Pipe and Panel Insulation

Kingspan Insulation's ISO-C1 2.0 lb/ft3 density polyisocyanurate rigid foam insulation is listed under FM’s Approval Standard 4880, independently audited by Factory Mutual. We manufacture ISO-C1 polyisocyanurate as large buns, and subsequently fabricate into insulation panels, pipe insulation, or equipment insulation. Polyisocyanurate insulation is used in a wide range of applications from chilled water pipe insulation to refrigeration insulation to cryogenic insulation. Applications include:

ISO-C1 Manufacturing process

Insulated panels, including unfaced or structural insulated panels

  • commercial refrigeration insulation
  • warehouse insulation
  • walk-in cooler insulation and freezer insulation
  • refrigerated transportation containers
  • duct insulation

Fabricated foam shape for low to mid-temperature mechanical insulation

  • chilled water pipe insulation and equipment insulation
  • ammonia refrigerant pipe insulation
  • cryogenic insulation / LNG insulation
  • commercial HVAC insulation
  • tank insulation

Kingspan polyisocyanurate insulation is available in 2.0, 2.5, 3.0, 4.0 , and 6.0 lb/ft3 densities, and with variable sized buns which can result in reduced waste when cutting to particular dimensions - thus resulting in cost savings.

[ISO-HT pipe insulation is available for higher temperature applications such as hot water pipe insulation and low temperature steam pipe insulation.]
