PIRFORMATHERM®

PIRFORMATHERM<sup>®</sup>

Maximise floor space and thermal performance. Minimise thickness.

Fletcher Insulation’s Pirformatherm® achieves superior thermal performance (R-Value) through achieving the lowest thermal conductivity ratings.

It is the smart, lightweight solution with high insulating properties – and sound financial reasons to specify, install and recommend it – for commercial builders, plasterers and resellers.

  • Designed to build in more floor space
  • Lower thermal conductivity and slimline profile
  • Designed to perform under Australian conditions
  • Environmentally aware
  • Closed Cell structure
  • Excellent fire properties

In technical terms, Pirformatherm® Rigid Board Insulation is a Polyisocyanurate (PIR) core sandwiched between two layers of foil facing, autohesively bonded to the insulation core during manufacture. As you can see, it has excellent fire properties, thermal conductivity and other physical characteristics.
