NRG GREENBOARD™ WALL SYSTEM

NRG Energy Efficient Building Systems is pleased to announce a revolution
in lightweight cladding systems. NRG Building Systems is the first and only
company to achieve CodeMark™ Accreditation and BAL29 Fire Testing on
EPS cladding systems.

NRG Greenboard™ Wall System has CodeMark™ and BAL29 Accreditation
on the complete system, comprising of NRG Greenboard™, fixings, render
beads, polymer modified render, reinforced mesh, textures and membrane
coatings. NRG is the only company to achieve CodeMark™ Accreditation
making the system fully BCA compliant. NRG Greenboard™ has legislated
product acceptance nationwide, giving the consumer total piece of mind
and confidence.

NRG Greenboard™ has passed extensive fire testing procedures (in
accordance with AS1530.8.1-2007), by global testing company Exova
Warringtonfire, that enables NRG Greenboard™ to comply in BAL29 areas
(Bush Fire Attack Level). Used in conjunction with NRG Batten System,
(NRG Battens) increases the R-Value to 3.31R.

Insurance companies are now insisting that EPS cladding systems have BAL
Rating and CodeMark™ Accreditation. Why risk a product that insurance
companies will reject. Once again NRG Greenboard™ gives the designer,
certifier, builder and customer total confidence and piece of mind.

For further enquires, please contact NRG on the details below.

Total Thermal R-Value 3.48
