  • Exceptional thermal qualities
  • Acoustic values
  • Reinforced with 160g/m2 fibreglass mesh for high impact strength

NRG Greenboard™ is an Insulated Wall Panel that combines exterior cladding with insulation so designers can achieve the 6-star energy ratings that have been introduced into the building code. NRG Greenboard insulated core of high quality expanded polystyrene, positions the NRG Greenboard cladding insulation options from 1.92 R to 3.96 R. Creating an exterior dual cladding system, as a thermal exterior building envelope.

  • BAL29 – NRG Greenboard has passed extensive fire testing procedures (in accordance with AS1530.8.1-2007)
  • NRG Greenboard remains inert, is non-toxic, odour free and nonbiodegradable
  • No CFC’s or HCFC’s foam agents are used in its manufacture, so
    NRG Greenboard™ causes no damage to the ozone layer
  • Effective installation of NRG Greenboard™ can cut carbon dioxide emissions by up to 50%
  • The R-value of NRG Greenboard does not deteriorate during its lifetime; therefore the reduction in emissions lasts the full lifetime of the building
  • The energy used to manufacture NRG Greenboard is recovered within six months by the energy saved in the building in which NRG Greenboard is installed
  • Typically, for every kg of oil used in NRG Greenboard manufacturing, about 200kg will be saved in reduced heating demands
  • All NRG Greenboard waste is recycled, through installation of off-cuts in the wall cavity or it can be granulated and mixed with virgin material
  • 10 years NRG warranty from the date of purchase*

Thermal Rating for Greenboard Wall System

What is an R–value?

All insulation materials are rated for their performance in restricting heat transfer. This is expressed as an R–value which is the measure of material’s resistance heat transfer (Thermal Resistance). The higher the R–value, the greater the insulating effects.
