Add a contemporary, low-maintenance finish to your outdoor space with Trex Transcend® Lineage Composite Decking. Designed for long-lasting performance and easy installation, this board is perfect for trade professionals and DIY enthusiasts looking for a premium decking solution. Available from TJ O’Mahony, it delivers the aesthetic of timber with none of the ongoing upkeep.
Finished in Island Mist — a subtle, coastal-inspired grey with natural woodgrain detailing — it creates a fresh, modern look for patios, garden decks, and commercial outdoor areas. Part of the durable Trex Transcend Lineage range, it’s engineered to resist rot, warping, splintering, fading, and staining, ensuring your deck looks great year after year.
The grooved edge profile is designed for use with a hidden fastening system, giving a smooth, screw-free surface that’s safe underfoot and visually clean. At 4.88 metres long, it reduces joins and helps maintain straight lines across larger deck areas, speeding up installation and improving overall aesthetics.
Made from high-performance composite material, there’s no need for sanding, staining, or sealing — just occasional cleaning to keep it looking fresh.
Key Features:
Island Mist Finish: Soft, coastal grey with natural woodgrain texture.
Grooved Edge Profile: Compatible with hidden fixings for a smooth, professional finish.
Durable & Low Maintenance: Resistant to rot, warping, splintering, and fading.
4.88M Board Length: Fewer joins for a clean, continuous look.
Premium Composite Core: Designed for long-lasting performance in all weather.
Start with a perfectly straight first board and use the recommended hidden fastening system for consistent spacing across the deck. Allow for expansion gaps at board ends and follow correct joist spacing — this will ensure a smooth, professional finish and showcase the Island Mist colour beautifully.
