Japanese process of Yakisugi

The range is available in 10 exclusive colours, from mountain grey to sunset orange, and adds a splash of colour to any environment. Inspired by yakisugi, the process of charring the timber, IRO – which is Japanese for ‘colour’ is crafted using an intricate seven-step process that uses the most innovative timber technology.

Each stage contributes to our products’ texture, durability, and appearance. The result is a versatile product that blends seamlessly into any environment, whether it’s the countryside or city.

IRO is UV-stable, low-maintenance, long-lasting, and HVOC-free, meaning the product is both child-friendly and pet-friendly.

IRO is heat enhanced and coated in a wood cream

This makes the product more durable and offers a more striking grain appearance than its traditional cladding and decking counterparts.

Life in colour.

Available in a range of 3 colours to complement every environment.
