• MegaBoard used on Class 2 Development in Adelaide

    The Builder used MegaBoard (a Sorrel Cement Board) rather than traditional Fibre Cement Boards as the exterior cladding due to increased performance, stability and low energy embodiment.

Non-Combustible Water-Resistant Mould and Mildew Resistant Termite Resistant Impact Resistant

External Cladding

External Cladding

MEGABOARD™ is the generic term we also apply to our range of cladding boards that are multi-purpose with wide ranging applications. MEGABOARD™ is also a cementitious board manufactured to exact performance standards and has been evaluated by third party assessment. Applications  have also been carefully examined and bench-marked against the requirements of the National Building Code and where there is compliance to standards, performance criteria have been evaluated and verified by third party endorsement.

MEGABOARD can be used for multiple applications: –

  • Cladding board external 8mm
  • Cladding board internal 8mm
  • Flooring substrate 20mm
  • Wet areas 8mm
  • Shed lining 8mm
  • Soffits and Eaves 6mm
  • Fencing 12mm
  • Tile backer 6mm
  • Stone facade substrate 12mm

Manufactured using Sorrel Cement rather than Portland Cement, MEGABOARD has some significant advantages over its competitors. The manufacturing process used to manufacture Sorrel Cement boards is significantly different than traditional Portland Cement boards. Traditional boards require being cured at high temperatures which increases because the embedded energy in the boards, Sorrel Cement boards are cured at room temperature. The difference in that embodied energy is significant. Sorrel Cement boards have extremely high compressive strength, are fully recyclable, do not contain or release VOC’s, have low embodied energy and absorb\ C02 making MEGABOARD  also one of the most environmentally responsible products on the market.


ReGen Building Solutions  therefore has also invested significantly in research, testing and R&D to ensure that it performs to the highest standards. We also understand that the facade of your home is critical to the aesthetics and provides the substrate for the final finish.

All substrates need a coating system that protects, enhances and provides excellent aesthetics for the purpose because it is being used. ReGen Building Solutions have also researched out the best coating products with suppliers for internal and external applications. Wattyl/Solver/Granolite have provided both an internal and external specification and have tested MEGABOARD at their laboratory. The results that were excellent providing a custom specification for both internal and external usage MEGABOARD Technical.

Coating applications notes:

Before building any structure it is important to understand how you would like it to look at the end. It is for this reason ReGen Building Solutions has sought specifications from some of the most well known suppliers of render/texture and painting products in the Australian market.

Because it is important if coating any substrate that the boards have  also been installed appropriately in accordance with the build system External Cladding and that paint and render/texture specification sheets are followed. Wattyl Granosite has 664% elasticity. This means it has the capacity to bridge cracking that may become apparent due to building movement. Wattyl GranoSkin Membrane elastomeric  elongation is 768%. Consider the soil that you are on and consider the potential for building movement. A well applied system that will protect the substrate, reduce risk of water damage and maintain the aesthetics of the building.
