TimberTech vs Trex vs Fiberon: Flagships 2026

None of the three wins outright, because their flagships are built for different problems. TimberTech AZEK Vintage is PVC with built-in heat dissipation and the deepest darks of the three, which makes it the pick for a dark board in a hot climate, and it carries a 50-year structural warranty. Trex Transcend is capped composite with 14 colours across three collections, the most convincing hardwood look and the brand name a buyer is likeliest to recognise, at 25-year structural coverage. Fiberon Paramount is the value flagship: also PVC, also 50-year structural and 30-year fade and stain, at the lowest board price of the three at about $5.10 per linear foot. So the decision order that works is climate and exposure first, then appearance, then price, because the material split between PVC and composite settles more than the badge does.

At the flagship tier, yes, and it stays cheaper through the surrounding system too. Paramount runs about $5.10 per linear foot against $5.40 for Trex Transcend and $7.20 for TimberTech AZEK Vintage, which on a 320 square foot deck is roughly $3,480 in boards against $3,690 and $4,915. Fiberon's brand-wide installed range of about $48 to $95 per square foot also starts below the $50 to $110 quoted for the other two. The fastener economics compound it: Fiberon Stowaway covers about 100 square feet per $138 box, roughly $1.38 per square foot, against $1.70 for TimberTech CONCEALoc and $1.78 for the Trex system. Railing and stairs price marginally lower as well. The gap against Trex is small enough to ignore if you prefer the palette; the gap against AZEK Vintage is a real budget decision.

Fiberon Paramount and TimberTech AZEK Vintage tie, both carrying 50-year structural coverage plus 30-year fade and stain. Trex Transcend carries 25 and 25. That gap is not marketing; it tracks the material. Both 50-year boards are full PVC with no wood fibre in the core, so there is nothing in them for water to swell or rot, and the longer structural paper is priced on that fact. Transcend is capped composite, a wood-fibre and recycled-plastic core under a polymer cap, which performs well but is a different risk profile. Two practical notes apply to all three. Registration after installation is required, and coverage is generally transferable to the next owner, which is worth keeping paperwork for if you might sell. Terms are published by each manufacturer and do change, so confirm current wording before you buy.

The per-linear-foot and per-square-foot figures in this guide are board prices at 2026 first-quarter retail, so they are material only. Installed cost adds framing, hardware, labour, railing, stairs and permit, which brand-wide lands at roughly $48 to $95 per square foot for Fiberon and $50 to $110 for Trex and TimberTech depending on line, pattern and region. The reference builds show how far apart those two numbers sit: a 16 by 20 deck carrying about $3,690 of Transcend boards comes in near $24,000 installed. That is the single most useful thing to understand about composite pricing, because it means the board upgrade you agonise over is often a small share of the bill, while railing choice, stair count, board pattern and regional labour move the total far more. Labour alone swings roughly 0.92 in the South to 1.28 on the West Coast.

Each brand runs a big-box channel and a professional dealer channel, and the difference between them matters more than most buyers expect. Trex sells through Home Depot plus Trex Pro Platinum dealers, TimberTech through Lowe's plus AZEK Pro dealers, and Fiberon through Lowe's plus its own pro network. Big-box stores stock partial palettes, typically the value lines and a few popular colours, so the full flagship palettes, Transcend Lineage, AZEK Vintage and Paramount, usually mean a pro-dealer special order with a two to four week lead time. Plan around that in two ways. Order long-lead boards while the permit is in review rather than after framing is done, and order the full quantity including pattern waste in one go, because a mid-build top-up weeks later risks a different production batch and a visible colour difference across the deck.

In three situations, clearly. If the deck sits in full sun, PVC runs cooler than wood-flour composite at the same colour, and AZEK Vintage adds engineered heat dissipation on top of that. If it is coastal, lakeside or in a pool splash zone, a board with no wood fibre has nothing to absorb water, which is exactly what the 50-year structural warranty is priced on. And if you simply want the longest coverage available, both PVC flagships offer 50 years against 25 on Transcend. Outside those cases the argument weakens. Capped composite gives a more convincing hardwood look, Transcend offers 14 colours against six, and at $5.40 per linear foot it undercuts AZEK Vintage by $1.80. Note that Fiberon Paramount muddies the usual framing: it is PVC at a board price below the composite flagship, so PVC is not automatically the premium choice.
