Fire-retardant, Natural Tones Cladding

Fire-retardant surface with a 10-year maintenance interval

The durable, fire-retardant cladding panel is designed for high-fire-class P1 buildings, including schools, nursing homes, and apartment blocks. Its natural-toned surface enhances the visibility of wood grain patterns while providing effective protection against UV rays and moisture. This fire-retardant cladding is industrially painted to meet B-s1, d0 fire class standards, eliminating the need for on-site painting after installation. The maintenance interval for these fire-retardant, durable exterior cladding panels is every 10 years.  

NATURAL TONES exterior cladding is always manufactured in concealed panel formats to maximize weatherproofing. The fixing marks remain hidden under the next panel, and moisture and contaminants cannot be absorbed into the wood through them. RST hooks or nails should always be used to fix the NATURAL TONES exterior panels. The panels are also end-jointed, which allows for flexible extensions and reduces material waste.

NATURAL TONES fire-retardant, durable exterior cladding is available in seven different shades: Burnt Caramel, Dark Chocolate, Dark Rhum, Ocean Gray, Roasted Wheat, Smokey Black, Larch

Due to the natural variations in the wood surface, you may observe subtle differences in the translucent tones among different batches of panels. To achieve a cohesive and beautiful exterior for your project, it is important to accurately calculate the exact quantity of exterior panels you need when placing your order.
