A 146 × 24 mm straight-grain WPC decking board, co-extruded in one piece from wood-plastic composite. Its 146 mm face is wider than a standard narrow board, which means one less seam per run — the deck reads as a single continuous surface, and there's simply less cutting, less clipping and less labour per square metre. At 24 mm deep it stays light, so it asks less of the joist spacing and sub-base — a real advantage on balconies and rooftop terraces where added weight is a problem. The open channels let air and water pass through, so nothing pools and nothing stays damp: no rot, no mould, no termites.Compared with the heavier 140 × 30, the 146 × 24 is lighter and uses less material — the value pick for gardens, balconies, guesthouses and light commercial leisure areas.
