Grey Smooth Composite Cladding Board – 3.6m x 157mm Exterior Wall Cladding

Get a modern look for your walls using the Grey Smooth Composite Cladding Boards. Finished in a sleek grey colour, these 3.6m boards are perfect for those who want to achieve a modern appearance without having to deal with the maintenance requirements of traditional wood cladding.

Unlike woodgrain cladding, the smooth surface creates a more uniform, contemporary appearance. The boards are especially good for garden rooms, outdoor kitchens, wall panels around aluminium pergolas and other modern structures.

The boards are made from composite material that is resistant to ultraviolet light.

Why choose our Grey Smooth Composite Cladding?

• Clean, smooth finish – A great alternative to traditional woodgrain cladding. The subtle surface gives exterior walls a neat, contemporary appearance without pronounced timber patterns.

• Low-maintenance composite construction – No regular painting, staining or treating required. Spend less time maintaining your exterior walls and more time enjoying your garden.

• UV protection for outdoor use – Manufactured with UV protection to help minimise the effects of prolonged sunlight exposure on the surface.

• Long 3.6m cladding boards – Cover larger wall sections with fewer joins, helping create a cleaner-looking installation.

• Versatile grey colour – Works particularly well alongside anthracite windows, black aluminium pergolas, rendered walls and natural stone paving.

• Great for new builds and renovations – Whether you're finishing a newly built garden room or refreshing an older outbuilding, these boards offer a straightforward way to improve its appearance.
