Trex vs AZEK

Why this page exists

A materials decision in disguise

Trex vs AZEK is composite vs PVC. Settle the material question first and the brand question mostly answers itself.

The premium, quantified

AZEK runs $15–$30 more per square foot installed. We show what that buys, and the yards where it buys nothing.

Heat and water, told straight

PVC genuinely runs cooler and shrugs off water. Brand claims get treated as directional, not gospel.

Same backyard, both boards

Render your yard in Trex composite and AZEK PVC side by side. The look difference is real and very visible in a render.

Trex vs AZEK

Quick answer: AZEK (cellular PVC) beats Trex (capped composite) on heat, moisture, weight, and warranty length, and it costs $15–$30 more per square foot installed. Trex wins the value equation everywhere those advantages don’t bite: shaded yards, moderate climates, budgets that prefer a bigger deck over a pricier board.

The verdict

Buy the conditions, not the brand. Full-sun southern exposure, a pool edge, or salt air: AZEK earns its premium. A shaded suburban backyard in a temperate climate: Trex composite delivers 90% of the experience and leaves thousands in the budget. Then let the tiebreaker be visual: render both materials on your own photo and look.

Cost assumptions and sources

U.S. planning allowances in USD for a simple, single-level deck, including ordinary materials and contractor labor. These are PaperPlan editorial assumptions, not surveyed averages or a local quote.

• Pressure-treated: $25 – $40 / sq ft installed (USD)
• Composite: $45 – $70 / sq ft installed (USD)
• PVC: $60 – $90 / sq ft installed (USD)

Multiply deck area (width × length in feet) by the selected installed rate, then round each end of the range to the nearest $100.

Demolition, permits and engineering, taxes, stairs, railing, roofs, unusual foundations and difficult site access need separate quotes. Location, product selection and labor can put a real bid outside these ranges. Canadian projects need local CAD pricing.

The manufacturer sources below explain scope and cost drivers; they do not validate PaperPlan’s exact installed-rate bands. Supplier material estimates should not be compared directly with an installed project budget.

• TimberTech: understanding deck costs: Separates decking, railing, labor and substructure, and explains the impact of site and project features.

Common questions

Is AZEK worth the extra cost over Trex?

When heat, water, or horizon dominate (full-sun exposures, pool surrounds, coastal air, or an own-it-forever plan), yes, the PVC premium buys real daily comfort and longevity. In a shaded, temperate yard the honest answer is often no: capped composite performs beautifully and the difference funds a bigger deck or better railing.

Is AZEK the same company as TimberTech?

Yes. The AZEK Company owns the TimberTech brand, and the PVC boards are sold as “TimberTech AZEK.” So Trex vs AZEK is a cross-company comparison, but TimberTech vs AZEK is not; we keep a separate page for that exact confusion.

Does AZEK really stay cooler than Trex?

Directionally, yes: cellular PVC is less dense and holds less heat than wood-filled composite, and lighter colors amplify the effect. The specific “degrees cooler” numbers in brand material come from controlled tests, so trust the direction, not the decimal, and choose lighter colors for any full-sun deck in either material.

Which looks more like real wood?

Genuinely subjective. Trex’s streaked multi-tonal boards read convincingly woody at a glance; AZEK counters with deeper embossing and richer solid color, especially in pale tones. This is precisely the call a spec sheet can’t make. Render your yard in both and your eye will pick in seconds.
