Tarimatec vs Trex.
A European mineral-rich composite system versus a US recycled-polyethylene deck board. An honest, spec-by-spec comparison — including where Trex still leads.
Short answer: Tarimatec and Trex are both composite decking, but different materials. Tarimatec is a European rice-husk-and-limestone stone composite sold as a full deck-cladding-louvre system; Trex is a US recycled-polyethylene and wood-flour deck board. Trex holds North-American fire and code ratings Tarimatec does not; Tarimatec leads on design range, pool-grade slip and its verified EPD.
Built for different briefs.
Trex built the North American category — well — on recycled polyethylene and wood flour, sold as a deck board. Tarimatec comes at it from the other direction: a mineral-rich PVC composite (rice husk and crushed limestone) engineered in Europe as a full architectural system, from deck to façade to louvre. Neither is “better” in the abstract.

Trex publishes North-American fire and code ratings Tarimatec does not yet carry. If your project is fire-code-driven, tell us early. If it's design-driven, this is where Tarimatec pulls ahead.
Honest guidance.
Choose Tarimatec when…
You want a coordinated deck + façade + louvre system, European design finishes, pool-grade Class 3 slip, and an EPD-verified material story.
Choose Trex when…
Your project is driven by a specific North-American fire/code rating Trex publishes, or by big-box availability and a US residential track record.
Where Trex wins, where Tarimatec wins.
Both boards are engineered to outlast wood, resist rot and shrug off the maintenance a timber deck demands. The honest differences are about origin, range and code. Trex wins where a project is driven by a specific North-American fire or building-code rating that Trex publishes and Tarimatec does not yet carry, and where big-box availability and a long US residential track record matter most.
Tarimatec wins where the brief is design-led: 31 European tones and three finishes, pool-grade Class 3 / R11 slip resistance, a Tecnalia-verified EPD, and a coordinated system that carries the same colour from the deck up the wall and into an AXEL louvre. It is a mineral-rich stone composite, not a wood-flour board, so there is no wood to feed rot or mould.
For Canadian decks, freeze-thaw and UV are the real test. Tarimatec’s low water absorption (0.38–0.59% at 24 hours, tested to EN 317) limits the moisture uptake that drives freeze-thaw movement, and its salt-spray colour change of 1.25 ΔE points to strong colour hold under sun and coastal air. If you are cross-shopping the wider market rather than these two brands head-to-head, see our Trex alternative in Canada guide.

Head-to-head questions.
Is Tarimatec better than Trex?
Neither is better in the abstract — they are built for different briefs. Tarimatec is a European stone composite with a wider design range, pool-grade Class 3 slip and a verified EPD; Trex is a US wood-flour composite with published North-American fire and code ratings and wide big-box availability. Choose by what your project is driven by: design or code.
What is Tarimatec made of compared with Trex?
Tarimatec is an Ecofiber-Stone composite of rice-husk fibre, crushed limestone and PVC — a mineral-rich board with no wood flour. Trex is a wood-plastic composite of recycled wood flour and polyethylene. The difference in composition is why Tarimatec has no wood to rot and holds a low water-absorption figure.
Does Tarimatec have a fire rating like Trex?
Tarimatec carries a European Euroclass Bfl-s1 reaction-to-fire classification (EN 13501-1). Trex publishes North-American fire and building-code ratings that Tarimatec does not yet carry. If your project is fire-code-driven, tell us early and our specification team can advise.
Is Tarimatec more expensive than Trex?
Tarimatec sits in the premium tier and is quoted per project in CAD, with samples from $5. Trex spans good-better-best price tiers and is widely retailed across North America. The best way to compare value is to order a sample, then request a quote with your dimensions and colour.
