ISO-C1 Overview
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:
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 2.01, 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.]
1FM 4880 approval only applies to the 2.0 lb/ft3 density

1 All properties were measured at temperatures at or near 75° unless otherwise indicated, and all test values were obtained from independent certified testing laboratories.
2 These are nominal values obtained from representative product samples, and are subject to normal manufacturing variances.
3 Average value through the foam cross section of tested sample.
4 Above 300°F, discoloration and charring will occur, potentially resulting in an increased k-factor in the discolored area.
5 Table 1 includes the paragraph numbering system utilized within Section 12 of ASTM C591.
6 Thermal Conductivities (k-factors) at Low Temperatures: ASTM C591 is the Standard Specification for Unfaced Preformed Rigid Cellular Polyisocyanurate Thermal, and is arguably the key Standard used by insulation system end-users and engineer/specifiers to guide decision-making. Compliance with ASTM C591 is often a prerequisite within an insulation Request for Proposal.
7 Frequent and severe thermal cycling can produce dimensional changes significantly greater than those listed here. Special design considerations must be made in systems subject to severe cycling.
