Guariuba, also known as Oiticica, is a high-quality South American hardwood valued for its unique appearance and strength. The heartwood begins as a bright yellow tone and gradually darkens to a rich brown or reddish-brown shade, often displaying a striking golden glow depending on the light. Its gently wavy grain patterns create visually appealing and dynamic façade designs.

With a natural durability class 1, Guariuba offers excellent resistance to wear and external influences, ensuring long-lasting performance in demanding exterior applications. Combined with the Forestlines aluminium clip system, it guarantees fast installation and a clean, concealed finish.

Forestlines – Innovation in Timber Cladding

Forestlines introduces a revolutionary circular façade system that elevates untreated FSC-certified timber to an exceptional performance level. Through scientific innovations such as micro-compartmentation and advanced heat conduction, untreated wood achieves a fire reaction class B, a unique accomplishment within the industry. This performance is the result of years of research and extensive fire testing.

The system enables full personalisation in wood species and board width, minimises cutting waste and optimises dimensional stability. Even lesser-known timber species gain architectural potential within this engineered approach.

Awarded fourteen international prizes, including the Red Dot Award and the German Design Award, Forestlines is globally recognised for its innovation. The system offers fast installation, concealed fixing, competitive pricing and a scratch-resistant coating. Developed in collaboration with craftsmen and architects, it is produced in-house using high-quality materials.
