Smooth Plank

Cemintel Smooth Plank provides a flexible, external cladding option. It is ideally used as a complete external cladding system, or for second storey additions.

Planks are available in two widths and can be painted, or stained, to create the desired finish. The look is completed with a strong shadow line from the plank overlap. These planks provide for fast coverage, as they can be nailed directly to the frame, providing a drained cavity solution.
