NRG Greenboard

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 codes throughout Australia. NRG Greenboard’s insulated core of high quality expanded polystrene offers high Thermal ratings creating an exterior dual cladding system.

Greenboard Insulated Wall Panel is a lightweight, energy efficient product and once coated the system provides a weather resistant, seam free rendered finish.

Austech Queensland carry stock of NRG Greenboard and it’s components at our Eagle Farm Warehouse for immediate delivery.

NRG Greenboard  Advantages:

  • Reduced Energy costs in the home or business
  • Enviromently friendly (can be recycled or use off-cuts for internal wall insulation)
  • 98% Entrapped air
  • Added fire retardentNRG-CodeMark-banners
  • Design flexibilty
  • full range of coloured finishes and styles
  • Vermin retardent
  • No CFC used in the manufacturing process

Insulation Qualities

All insulation materials are rated for their performance in restricting heat transfer. This rating is expressed as an R-value which is a measure of the material’s resistance to heat transfer (thermal resistance). The higher the R-value the greater insulating effect.

Total Wall R-value for using Greenboard™
Thickness (mm) 40mm 60mm 75mm 100mm
R-value on total wall 1.92 R 2.44 R 2.83 R 3.48 R

Sound Rating

NRG Building Systems have tested the 60mm NRG Greenboard as a total wall system and the acoustic performance result was Rw35,Ctr-6.  The NRG Greenboard walling system can be further enhanced by using a “sound rated” insulation batt. Please refer to insulation manufacture’s specifications on the below NRG Greenboard website.

Fire Retardant

NRG Greenboard contains a flame retardant additive and will not support fire, with a spread of flames index is zero. If in a fire situation the toxic fumes are no greater than that of timber and other building materials.

Grooved Panels

The surface of the NRG Greenboard panel is Grooved both sides allowing the inside surface to breathe and channel any possible condensation away through the Grooves, downwards to the base of the wall. This is particularly important where “insulation” or “breather sarking” is used.

The additional advantage being that when the Grooved face of Greenboard is rendered the system becomes stronger as the render gets into the Groove to form a core shape for better adhesion and a stronger more rigid Greenboard system.

Easy Installation 

NRG Greenboard’s lightweight panel size is 2500 x 1200 allows installers to cover the external walls quicker and easier. For the builder and their client, NRG Greenboard gets the project to lock up stage quicker allowing other trades to start and complete their tasks. Instructions are available on the below NRG Greenboard website or can contact Austech Queensland staff for assistance and quotes.

NRG Greenboard render finish

Reinforced render is applied to the Greenboard substrate at approximately 4-8 mm in thickness which allows qualified applicators to screed out usual imperfections and form a seam free level 5 finish. NRG recommends the render over Greenboard should be specified by a coating manufacturer.

 NRG Building Systems has achieved CodeMark on Greenboard Insulated Wall Cladding meaning Greenboard complies to the BCA (Building Code of Australia).
