Castellation Composite Cladding 25mm

Give walls, ceilings and façades a modern timber look with the low maintenance composite castellation cladding from NewTechWood. Castellation boards feature a deep ribbed profile that creates elegant shadow lines, while UltraShield® capping protects against UV, salt spray, stains and pests. Built from 95 % recycled wood fibre and HDPE, the boards install with hidden clips, ventilate naturally, and never need paint or oil. The 25-year residential warranty means you can enjoy piece of mind in every outdoor space.

Why Castellation Stands Out

• Distinct 25mm ribs deliver modern architectural shadow lines.

• UltraShield 360° capping resists fade, stains, mould and termites.

• Concealed fix clip system for faster, cleaner DIY installation.

•  Made from 95% recycled materials keeps waste out of landfill.
