The products PIR core is manufactured by using zero ODP and low GWP blowing agents. It has an advantage over traditional PIR insulation boards due to the decreased thickness (even 15% thinner than the common PIR boards) and even 30% better U values achieved.

  • Applicable to both existing and new buildings,
  • Great thermal performance - a super low lambda value of 0.021 W/mK,
  • Low emissivity values especially when added to the metal lining or timber batten systems,
  • Helps to optimise interior space, by using 50% less insulation than traditional products,
  • Highly environmentally friendly.
