Advantages of NRG Greenboard

Written By: - Apr• 18•11

Advantages  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. Greenboard‘s insulated core of high quality expanded polystyrene puts the Greenboard insulated panel in the best place of the building, as far towards the outer side as possible.

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

Advantages  Greenboard

CodeMark Certification

All building products must comply with the BCA (Building Code of Australia). NRG Building Systems has achieved CodeMark on Greenboard Insulated Wall Cladding meaning Greenboard complies to the BCA.

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.

Sound Rating

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

Fire Retardant

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

Grooved Panel

The surface of the 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 to Use

Greenboard‘s lightweight panel size is 2500 x 1200 allowing installers to cover the external walls quicker and easier. For the builder and their client, Greenboard gets the project to lock up stage quicker allowing other trades to start and complete their tasks.

Greenboard requires less energy to produce than other traditional building materials and contains no CFC’s nor HCFC’s. Greenboard does not contain ozone depleting substances and none are used in the manufacturing of this product. Greenboard can be recycled or NRG recommends left over Greenboard can be placed in the walls as extra insulation.

Greenboard contains a termite retardant (Bifenthrin) and NRG uses 62% more in their product than the minimum required.

Render Levels of Finish

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