Additional information

Millboard® Shadow Line+ Cladding combines precision engineering with timeless design. Each board is moulded from real painted timber, replicating the refined grain and sharp lines of tongue-and-groove cladding while offering all the benefits of cutting-edge composite technology.

Unlike traditional timber cladding, Shadow Line+ is non-porous and resistant to algae, insects, rot and UV damage, ensuring your façade stays looking its best with minimal upkeep. The surface won’t warp or fade, even in harsh or changeable weather conditions.

Thanks to its hidden fixings and tongue-and-groove design, Shadow Line+ installs easily and delivers a consistent, seamless finish across large areas. Perfect for everything from full façades and feature walls to outbuildings and garden rooms, it’s a smart, stylish, and long-lasting alternative to wood.

Shadowline+ is also fire-rated (D-s3, d0) and comes in a curated palette of nine contemporary colours to suit a variety of architectural styles and personal preferences.
