PIC is a closed cell rigid foam board insulation.

PIC can be supplied in sheet form and pipe sections. PIC foams are fine cellular rigid foams.

Polyisocyanurate (PIC) comes in a range of densities from 32kg/m³
to 80kg/m³.

Polyisocyanurate (Polyiso) rigid foam insulation is designed to provide thermal resistance in residential and commercial building construction applications. For example, in exterior above-grade wall assemblies, a layer of rigid insulation is often specified to comply with the prescriptive R-Value requirements outlined in energy codes and standards
Highest R-Value per inch of any rigid foam board insulation

  • SABS 1383 of 1983 – Part 5.8
It has been shown to be compatible with construction materials – such as petroleum-based solvents in adhesives, paints, water repellent and preservative coatings, and in bituminous waterproofing. Not a affected by oil based waterproofing compounds.
Environmental with a compliant hydrocarbon-based blowing agent which has as zero Ozone Depletion Potential VP. It also meets HFC-, CFC- and HCFC-free specification requirements.



  • High compressive strength potential
  • Stable in tempearture range of -120°C to 120°C
  • High level of closed cells therefore offering high level of buoyancy

Compressive Strength

With direction of rise- PIC35 220kPa. Variations of +10% may be found. Test to SABS 1383 of 1983 – Part 5.7


  • It has excellent thermal conductivity and high compressive strength
  • Exhibits very good dimensional stability between 140°C and -100°C and can therefore be recommended with confidence in this temperature range
