Built for long-lasting performance with the look of real timber, Trex Transcend® Lineage™ Composite Decking – is a premium choice for trade professionals and serious DIYers alike. Available from TJ O’Mahony, this high-performance composite board delivers durability, low maintenance and a clean, contemporary finish that stands up to Irish weather year after year.
Finished in Biscayne — a light, coastal-inspired tone — this board brings a fresh, modern look to garden decks, patios and outdoor living spaces. Part of the advanced Trex Transcend Lineage range, it’s engineered with heat-mitigating technology to stay cooler underfoot compared to many other composite boards, making it ideal for sunny spots and family gardens.
The grooved edge profile allows for a discreet hidden fastener system, giving you a smooth, screw-free surface that’s both safe and visually sharp. Measuring 4.88 metres in length, it’s well suited to larger deck layouts, helping reduce joins and speed up installation time on site.
Unlike timber, there’s no need for staining, sealing or painting — just a simple wash down to keep it looking its best. It won’t rot, warp or splinter, making it a smart long-term investment for residential and commercial projects alike.
Key Features:
Premium Biscayne Finish: Contemporary, coastal-inspired tone with natural woodgrain effect.
Grooved Edge Profile: Designed for hidden fasteners and a clean, professional finish.
Low Maintenance: No staining, sealing or painting required.
Durable Composite Core: Resists rot, splintering, fading and weather damage.
Heat-Mitigating Technology: Designed to stay cooler underfoot in warm weather.
Long Length (4.88M): Ideal for larger deck areas with fewer joins.
Always install onto a solid, level subframe with correct joist spacing as per manufacturer guidelines. Use the recommended hidden fastening system for a tight, uniform finish and allow proper expansion gaps at board ends. Planning your layout before you start will minimise waste and give you that sharp, straight run every tradesperson aims for.
