Trex Composite Decking Lines Compared: Lineage vs Tropicals vs Select
When you’re choosing composite decking from Trex, there are a few different lines to consider. Each offers trade-offs in appearance, durability, price and comfort (especially in our hot Australian sun). Knowing those differences helps you pick the right one for your home and climate. Below is a breakdown of Trex Transcend Tropicals, Lineage, and Trex Select.
What Are the Basics (All Trex Composite Decks)
Before comparing, here are features common to Trex composite decking that matter in Australia:
Composed of approx. 95% recycled materials (plastic film, reclaimed sawdust, etc.)
Trex uses a protective shell around each board to resist fading, staining, mould and mildew
Boards come in grooved and square edges (grooved to work with hidden-fastener systems) which affects appearance and install style
Warranties vary by line: longer for the premium lines, somewhat shorter for more affordable ones
Trex Transcend Tropicals (“Transcend Tropical”)
What it is:
This is part of the Transcend line, focusing on more exotic, tropical-wood inspired colours. In Australia it’s often called the Tropicals range.
Colour & Appearance
Deep, multi-tonal streaks meant to mimic tropical hardwoods
Available colours in Australia include Havana Gold, Island Mist, Lava Rock, Spiced Rum, Tiki Torch
Rich, grainy look, which gives an upscale timber feel
Durability & Warranty
Backed by a 50-year limited residential warranty for structural performance and fade & stain resistance
Resistant to rot, splitting, warping, termites and mould thanks to the shell
Considerations (Pros & Cons)
Pros: Beautiful, high-end finish; very durable; one of the top choices if you want vivid colours and texture
Cons: Higher in cost (compared to Select); in strong sunshine the darker or richer colours can absorb heat.
Trex Transcend Lineage
What it is
Lineage is a newer (introduced to Australia in 2022) Trex line, built off the Transcend base, with added features around comfort underfoot (i.e. cooler in the sun) and on-trend colours/tones.
Colour & Appearance
More “tranquil”, lighter or more neutral colours that better reflect sunlight, giving a cooler deck surface
Available colours in Australia include Biscayne, Carmel, Hatteras, Island Mist, Jasper, Rainier and Salt Flat
Grain and finish simulates natural wood grain pattern
Unique Features
Heat-mitigating technology: Trex claims Lineage boards are engineered to stay cooler than other composite boards, especially under direct sun. This is a big benefit in many parts of Australia
Same high-quality protective shell. Resistant to fade, stain, warping etc.
Warranty & Durability
Also a 50-year limited residential warranty
Long-term performance expected to be excellent, especially in sun-exposed areas if you pick lighter shades
Trex Select
What it is
Select is a mid-tier Trex line: more affordable, simpler in appearance, fewer colour options, still composite and still much lower maintenance than timber.
Colour & Appearance
Less exotic or “tropical” colour range; more classic or neutral colours
Grain pattern is simpler, less streaking / less deep wood-grain than Transcend lines
Available colours in Australia include Malted Barley, Millstone and Whiskey Barrel
Durability & Warranty
Warranty is shorter than the premium lines: 35 years limited residential for Select
Still has protection from rot, splintering and mould, but the level of scratch resistance, UV fade resistance etc., is less robust comparatively
Considerations
Pros: Lower cost, easier to budget; still delivers a durable composite deck; simpler look may suit many Australian homes
Cons: Fewer choices in colour & texture; may show wear (scratches, fading) sooner under high stress or very sunny/hot exposure
Side-by-Side Comparison Table
| Feature | Transcend Tropicals | Transcend Lineage |
Select |
| Premium/tropical wood look & deep grain | ✔ Strongest of these three; exotic streaks, bold tones | ✔ High quality grain, more neutral/tranquil tones | ✘ Simpler grain / less streaking |
| Colour variety | Several vibrant tropical colours + earth tones | More colours than Tropicals; emphasis on cooler neutrals | Smaller palette, mainly classic/neutral shades |
| Heat mitigation / comfort in sun | Moderate (darker tones absorb more heat) | ✔ Engineered specifically to be cooler underfoot | Less focus on this; lighter colours help |
| Warranty (residential) | 50 years | 50 years | 35 years |
| Scratch / stain / mould resistance | Very high | High (similar technology as Transcend + Lineage) | Good, but not quite at premium line level |
| Cost | $$$ | $$$$* Newer Colours can be more expensive | $$ |
| Joist spacing requirement | 450mm | 450mm | 400mm |
| Best use cases | Feature decks, entertaining areas, showpiece, heavy use, want bold colours | Feature decks, hot climates, comfort, modern neutrals, balance of premium + comfort | Utility decks, smaller budgets, less demanding wear, simpler designs |
What to Consider in the Australian Context
Because of Australia’s climate (strong sun, heat, sometimes harsh weather), some special points are important:
- Choose lighter or neutral shades if your deck gets full sun. Darker colours look great but absorb heat. Lineage helps here.
- Warranty & regional compliance: Always confirm you get the proper warranty for your line; Trex Australia has specific documents
- UV stability / fade resistance matter more here than in many places. Premium lines like Transcend Tropicals and Lineage are better in that regard
- Substructure & installation still very important. Even the best board will underperform if installed poorly (poor ventilation underneath, wrong fasteners etc.)
- Cost vs lifespan: Premium lines cost more up front, but likely last longer with less visible ageing, which can mean better value over decades

Which One Should You Pick?
Here are some guidelines, depending on your priorities:
Want maximum style, bold colour, strong feature deck → Transcend Tropicals
Want comfort underfoot in lots of sun, cooler colours, modern aesthetic → Transcend Lineage
Want a solid deck for more modest budget, less demanding use, with good longevity but lower upfront cost → Select
Summary
Trex offers a spectrum:
Transcend Tropicals is about striking appearance
Transcend Lineage retains most of that premium performance but adds comfort (cooler in sun) and more subtle, trend-led tones
Trex Select is a mid-tier option that gives you many of the durability benefits and lowers the cost, but lacks some of the premium aesthetics and extended warranty of the top lines
