Shadow Line+

Introducing Shadow Line+, the evolution of our renowned Shadow Line boards. Undergoing stringent testing according to BS EN 13501-1 standards, the Shadow Line+ system achieves a Euroclass D classification, setting a new standard in safety and performance. What sets Shadow Line+ apart is its comprehensive fire rating, covering not only the cladding boards but also essential accessory items like the new Reveal Boards, Corner Profiles, and Coloured Head Screws.
