High Thermal Performance Insulation Panel

Product Introduction

PIRMAX HR PANEL is a modified PIR (Polyisocyanurate) rigid thermal panel that can be used in many applications. PIRMAX HR PANEL is the next generation in high performance insulation products for commercial and residential developments. Designed to achieve excellent thermal value where minimal cavity is available. 

PIRMAX HR PANEL has amongst the highest thermal values of rigid board insulation products, giving buildings continued thermal efficiency throughout their life span. PIRMAX HR PANEL is a light weight closed cell Polyisocyanurate foam core panel. Easy to handle and allows fast fixing to any application.

PIRMAX HR PANEL is CFC free with zero Ozone Depletion Potential (ODP), does not release Volatile Organic Compounds (VOC’s) and is manufactured in Australia.


  • Complies with AS/NZS 4859.1.
  • Amongst the highest thermal values of rigid board insulation due to the product’s low thermal conductivity.
  • Achieves an External Wall classification of EW in accordance with AS 5113:2016 testing.

  • Achieves excellent fire hazard results when tested to AS/NZS 1530.3.
  • Not corrosive to metal over time.
  • Able to custom manufacture to different sizes and facing colours.
