product overview

Trendplank Timber Cladding

Mortlock Timber

Trendplank excels in any environment. A concealed fixed cladding system with a range of corner trims and end stops for the perfect finish, Trendplank is ideal for both external and internal timber cladding for walls and ceilings. Naturally timber moves according to the elements it is exposed to in the environment. Since we cannot control this phenomenon, Trendplank finds harmony with its environment by allowing for just the right amount of natural timber movement.

Expertly designed and engineered for maximum performance in both exterior and interior applications, Trendplank timber cladding offers a durable solution that will continue to impress for years to come. Trendplank has been designed for efficiency and ease in installation, and maximum durability once the project is complete. During installation, the boards can be joined off stud thanks to end matching. End matching is a tongue and groove profile that improves water proofing and eliminates the need to measure and trim the ends of the boards. This will enable you to save time and minimise waste during installation.

Both vertical and horizontal installation is possible for wall applications with Trendplank, in either a timber frame or masonry construction. Pre-drilling is required, as is screw fixing. Trendplank can also be end-matched, end matching is applied to the ends of the boards so that they can be joined off the stud. End matching is a tongue and groove profile that improves waterproofing and eliminates the need to measure and trim the ends of the boards. This will enable you to save time and minimise waste during installation.

What is the R-value for timber cladding?

The R-value for 19mm hardwood timber cladding is R 0.12.

ATFA states that the thermal conductivity of kiln-dried hardwood (across the grain) is 0.16 W/mK. The R-value of a material is determined by dividing the thickness (in metres) by the thermal conductivity of the material so the R-value of 19mm thick kiln-dried hardwood is R 0.12. R = Thickness (m) / Conductivity (W/mK) =0.019 / 0.16 = 0.12 (m²·K/W).
