Premium 16mm fibre cement weatherboard with deep shadow lines for bold, contemporary facades. Part of the James Hardie Scyon™ range — resistant to termites, rot, fire and moisture damage. Available in 150mm and 180mm widths.
Scyon Linea Weatherboard is a 16mm thick horizontal fibre cement weatherboard designed for external cladding on residential and light commercial buildings. It is manufactured using James Hardie's Scyon™ formulation — a low-density cement composite that enables thicker profiles with deep shadow lines not achievable with conventional 9mm fibre cement.
At 16mm, Linea is the thickest weatherboard cladding available on the Australian market. The increased thickness creates bold, deep shadow lines between boards, giving facades a contemporary architectural presence that lighter-gauge products cannot match. Available in two widths — 150mm and 180mm — in 4.2m lengths, allowing designers to create classic, contemporary, or composite looks.
Linea resists shrinking, swelling, and cracking, and holds both dark and light paint finishes longer than timber when installed and maintained correctly. It is pre-primed, easy to install with standard tools, and backed by James Hardie's product warranty.
