Millboard Composite Decking is a moulded composite board that replicates the grain and texture of natural timber decking, supplied in various board profiles and colourways for garden and outdoor living projects. It is fitted using dedicated fixings and substructure components rather than nailing directly, and pairs with matching edging and trim pieces from the same range.
Unlike timber decking, it does not need sanding, staining or annual preservative treatment, and resists the splitting, splintering and algae staining that affect wood left outdoors. That makes it suited to households wanting the look of a timber deck with less upkeep over the years, particularly in shaded or damp garden areas where timber typically deteriorates faster.
