ThermaWallPlus® is fixed to a timber or metal frame to that meets Australian standards. The boards can be hung horizontally or vertically. Who stocks the product, can I purchase direct from RMAX?

BuilditEco Pty Ltd is the exclusive distributor of ThermaWallPlus® in Western Australia.
RMAX does not sell ThermaWallPlus® direct to the public.

Who can install the product?

BuilditEco Pty Ltd have teams of installers in the metropolitan and regional areas that install the complete package, from a sarking, the board itself and then render and texture coat it. Having one highly skilled team onsite ensures a quick installation time and less chance for there to be costly delays to your project.

Is ThermaWallPlus® available as a DIY system?

BuilditEco Pty Ltd will sell the system as a DIY package. We do insist on checking/auditing the installation process prior to it being rendered and texture coated. We would also sell all fixing materials required for your job. We would not recommend that you attempt the render and texture process unless you have previous experience with acrylic and polymer renders.

How does ThermaWallPlus® compare in price to bricks or fibre cement board?

ThermaWallPlus® saves time in erection costs due to the ease of installation. We do recommend that you discuss this with your local distributor, as transport and labour costs may have a bearing upon the overall figures. Savings are ongoing as ThermaWallPlus® also insulates thus reducing heating costs in winter and cooling costs in summer.

What is the fire performance of ThermaWallPlus®?

ThermaWallPlus® comprises an EPS (expanded Polystyrene) core that is made of self-extinguishing expanded polystyrene. (It self-extinguishes when the source of the flame is removed.) We have developed a system that allows us to us the ThermaWallPlus® system in areas up to BAL (Bushfire Attack Level) 19. For more information please contact BuilditEco.

What is the noise/sound resistance of the board?

No official tests have been conducted by RMAX, however with the use of other sound-inhibiting materials a wall made up of 40mm ThermaWallPlus® can obtain a rating of 40 STC.
