INEX>RENDERBOARD is an innovative, low carbon, high strength yet lightweight cement-based interior and exterior wall cladding suitable for both residential and commercial applications. At only 16mm thick with fixings to battens or top hats at a minimum thickness of 25mm, INEX>RENDERBOARD offers exceptional space-saving facade options — even when high-performance FRL or acoustic insulation is required. This makes it ideal for high-density areas.

Fire rating and acoustic

INEX>RENDERBOARD is non-combustible. It is approved for bushfire BAL-FZ construction and is certified to Fire Resistance Level of FRL 60/60/60.

INEX>RENDERBOARD on a timber frame with R2.5 insulation and 10mm plasterboard internal lining will deliver a sound insulation value of Rw/Rw+Ctr of 47/38. Insulation value will be will be higher (56/45) with a steel frame.

INEX>RENDERBOARD can be cut and worked just like comparable fibre cement sheets, but offers improved bending strength characteristics and finish quality.

INEX>RENDERBOARD systems can be fixed to timber or steel studs with spacing at maximum 600mm centres.

Material

INEX>RENDERBOARD is an advanced high strength, low carbon fibre reinforced Engineered Cementitious Composite (ECC) product, containing 60% of post-industrial recycled materials. It is toxin-free and is 100% recyclable.

Ease of Use and Handling

INEX>RENDERBOARD does not require any speciality tools or fixings. It can be ‘off stud’ joined thereby minimising waste on site. INEX>RENDERBOARD is a multi-purpose product enabling a wide choice of applications or expressions.

The smooth side of INEX>RENDERBOARD provides a minimum class 2 concrete surface and comes with an aris to create a ‘V’ joint along the long edges. This side can be coated with several approved paint systems of varying textures, or clear finished to retain the characteristic raw concrete look of INEX>RENDERBOARD. After installation, the ‘V’ joint does not necessarily require sealing and is dependent on the selected finishing system.

INEX>RENDERBOARD has a tongue and groove joint down each long side for a flush tight fit and to minimise any later joint cracking.
