Product Details

A bold black finish built for the outdoors

Black brings a sharp, contemporary edge to exterior spaces, and this composite wall panel is engineered specifically to handle life outside. Textured slats give the surface real visual depth, while the composite construction is built to resist weather and hold up season after season. The panels are UV resistant too, so the colour and structural integrity stay intact even after prolonged sun exposure, meaning your feature wall or cladding project keeps its sharp black finish for years rather than fading within a summer. It is a strong choice for garden walls, exterior cladding, fencing accents and outdoor living spaces where style needs to survive the elements.

Key features

  • Deep black tone for a bold, contemporary exterior finish
  • Textured slats add visual depth to garden walls and cladding
  • Weather resistant composite construction built for outdoor use
  • UV resistant, so colour and structure hold up under sun exposure
  • Pair with matching trims, corner trims and brackets for a complete finish

Complete the look: pair these panels with our Wall Panel Trim in Black for clean edges, our Corner Trim in Black for neat external corners, and our Brackets for Outdoor Panels, which we recommend for a secure installation.

Easy to install

Installation is straightforward and well within reach of a confident DIYer. We recommend using the dedicated outdoor brackets alongside a strong exterior grade adhesive for the most secure, weatherproof fit. Panels can be cut to size with a fine tooth saw to fit neatly around corners and fixtures, and the matching trim and corner trim pieces are available to give edges and external corners a clean, finished look. Most customers complete a garden wall or exterior feature area in a single session.

Delivery & returns

Dispatched within 48 hours with tracked UK delivery. Delivery is charged separately and calculated at checkout. Every order is covered by our returns policy and product warranty. See our Returns & Warranty page for full details.
