For long-lasting, low-maintenance decking that looks great and stands up to Ireland’s changeable weather, the Trex Enhance Composite Deck – Beach Dune Grooved 140×25 mm x 4.88 m is a go-to choice for both trade installers and DIY landscapers. Part of the proven Trex Enhance™ range, this grooved board combines authentic wood-grain aesthetics with composite performance — so you get the beauty of timber without the ongoing upkeep.
The Beach Dune finish offers a warm, natural tone that complements outdoor spaces from seaside patios to contemporary gardens. Designed to be installed with hidden fasteners in grooved edges, these boards deliver clean lines and a professional finish every time.
Key Features:
Composite Durability: Made from a premium mix of wood fibres and recycled polymer, these boards resist rot, splintering and mould — perfect for high-traffic decks, steps and seating areas.
Grooved Edges: Grooved board profile works with hidden clip fasteners for a flush, clean appearance and secure fixing.
Authentic Wood Grain Look: Beach Dune’s natural, sandy tones and grain detail give a timber-like finish without the maintenance headaches.
Low Maintenance: No sanding, staining or sealing required — a periodic clean with soap and water is all you need.
Fade & Stain Resistant: Designed to withstand UV exposure and common outdoor stains, keeping your deck looking sharp season after season.
Installation: Hidden fastener system (sold separately)
TJ’s Tip:
When planning your deck, allow a 5–7 mm gap between boards for drainage and airflow — essential in wet climates. Always install on a solid joist framework with appropriate spacing and use compatible Trex hidden fasteners for that sleek, screw-free surface.
