Greenboard Advantages CodeMark Certification & ENVIRONMENT

Posted on by

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.

Greenboard Advantages

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.

NRG GREENBOARD AND THE ENVIRONMENT

  • NRG Greenboard is comprised of 98% air and therefore only 2% polystyrene making it a highly efficient use of raw material.
  • NRG Greenboard remains inert, is non toxic, odour free and non-biodegradable.
  • 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 life time; 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. Either through installation of off-cuts in the wall cavity or it can be granulated and mixed with virgin material to make new products.

NRG GreenBoard CodeMark Certification

Posted on by

CodeMark is a new building product certification scheme. Third-party CodeMark Certification bodies evaluate and certify products to ensure they meet specified requirements of the Building Code.

CodeMark gives users the confidence that their building comply. Building materials, forms of construction and designs can come under the scheme.

Relevant legislation requires Building Certifiers, Designer, Architects, Builders, Home Insurance companies, Customers etc. to accept CodeMark certified products*.

WHY CODEMARK?

Impressive benefits for everyone:

  • Confidence – legislated product acceptance by building control authorities* (product opinions, appraisals etc. do not have the legislated acceptance);
  • Confidence – managing legal liability;
  • Confidence – national operation across Australia, therefore increasing market potential and improving efficiency;
  • Confidence – for designers, architects, builders, building control authorities, consumers and others who specify use, approve or invest in CodeMark certified products;
  • Confidence – underpinning the performance-based BCA through facilitating the use of new and innovative products; and
  • Confidence – listing current CodeMark certified products and accredited CodeMark certification bodies in Australia at the ABCB website.

NRG – CodeMark Accreditation Advantages

  • Offering increased credibility and acceptance, boosting consumer confidence in, NRG & Distributor network as well as ‘Accredited Installers’.
  • Assurance, that the NRG Greenboard system meets stringent national standards, encompassed by CodeMark  Accreditation.
  • Quality Assurance in the manufacturing process of NRG Greenboard, through constant product testing, reporting procedures etc.
  • Quality Assurance – NRG Greenboard profile cutting procedure, recording and documentation to the point of distribution by NRG.
  • Accreditation of installers, rendering and painting of the NRG Greenboard system through the introduction of ‘new structured’ training courses and information material, as this will, ‘underpin’ the ‘CodeMark’ Accreditation (essential).
  • Builders and Owner Builders, NRG Greenboard will also develop a ‘new structured’ training courses and information material and as well for this large market segment.
  • CodeMark Accreditation is a ‘holistic’ approach to this marketing strategy and encompasses all of the above. Without the authorised and accredited structure proposed, CodeMark accreditation would not be given, therefore it is essential that this fact is made known when promoting and marketing the NRG Greenboard system.

Additional benefits for Certificate Holders:

  • Confidence – offering increased credibility and acceptance of a certificate holder’s CodeMark certified products, whether established or new, therefore boosting consumer confidence in their organisation:
  • Confidence – entitling certificate holders to display the CodeMark “Mark of Conformity” ; and
  • Confidence – introducing a choice of certification bodies, therefore encouraging a timely and cost effective service.

Additional benefits for Certification Bodies:

  • Confidence – providing accreditation from an internationally recognised accreditation body, therefore increasing credibility;
  • Confidence – increasing acceptance and credibility of a certification body’s relevant product testing and evaluation methods; and
  • Confidence – entitling certification bodies to display the CodeMark “Mark of Conformity”.
