Boards are made from natural wood fiber and recycled HDPE, reducing the use of virgin plastic and preserving timber resources. The composite contains no toxic wood preservatives, and production off-cuts are reground and recycled in-house.
Suitable for installation over wood, steel or composite joists using hidden clips or stainless-steel screws, with a recommended joist spacing of 300-400mm center-to-center. Clean with a broom and occasionally wash with mild soap and water; no refinishing is needed.
Each production batch is tested for water absorption, slip resistance, UV stability and dimensional tolerance before shipment. Boards are produced to CE and RoHS requirements, and third-party inspection is welcome before shipment.
