For attractive, durable decking that stands up to Irish weather and everyday use, the Trex Enhance Composite Deck – Beach Dune Square Edge 140 × 25 mm x 4.88 m is a premium choice for both tradespeople and DIY installers. Part of the trusted Trex Enhance™ range, this square edge board delivers timber-like aesthetics with the long-lasting performance of composite — ideal for patios, garden terraces, and outdoor living spaces.
The warm, natural Beach Dune tone and realistic wood grain bring instant kerb appeal to any outdoor project, while the square edge profile offers a classic finish that can be fixed with surface screws.
Key Features:
Composite Strength & Durability: Manufactured from a high-performance blend of wood fibres and recycled polymers, this board resists rot, splintering, mould and moisture — perfect for high-use decking areas.
Square Edge Profile: Clean, classic board edge that works with both surface screws and hidden fastener systems (sold separately) for flexible installation.
Authentic Wood-Grain Look: Beach Dune’s sandy, natural hues and detailed grain give the look of timber without the maintenance hassle
Low-Maintenance: No sanding, staining or sealing required — simply wash down occasionally with soap and water to keep your deck looking sharp.
Fade & Stain Resistant: Built to handle UV exposure and common outdoor spills, giving long-lasting colour and performance.
Always install on a solid, level joist framework with consistent spacing — that’s essential for good ventilation and drainage in damp conditions. Leave gaps between boards for expansion and water run-off, and choose corrosion-resistant screws if surface fixing
