Trex vs AZEK

This one isn’t brand rivalry — it’s two different materials. Trex is capped composite; AZEK is cellular PVC. Here’s the honest trade, and how to see both on your own backyard before the deposit.

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.

How it works

  1. Upload a backyard photo. Use any phone photo of the build site. No measurements, no CAD file.
  2. Mark the deck area. Drag to outline where the deck goes. Add stairs or a railing line if you want them.
  3. Choose material and design. Pick composite, PVC, cedar, or pressure-treated. Compare looks on the same photo.
  4. Generate the render and share. Get a photorealistic render in seconds. Send it to the homeowner or attach it to a proposal.

Trex vs AZEK

Quick answer: AZEK (cellular PVC) beats Trex (capped composite) on heat, moisture, weight, and warranty length — and 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.

FeatureTrex (capped composite)AZEK (cellular PVC)
MaterialRecycled wood-plastic core with a polyethylene capCellular PVC through the full board — no wood fiber anywhere
Installed cost$40 – $75 / sq ft depending on line$70 – $90 / sq ft
Moisture & rotCap sheds water well; the core is wood-based, so cut ends and standing water deserve respectImpervious — the default spec around pools, hot tubs, docks, and coastal spray
Heat underfootDense core holds heat; dark Trex in July sun gets genuinely hotLighter, less dense board runs cooler. AZEK markets “up to 30° cooler” — treat the number as directional, the direction as real
Weight & handlingHeavy boards, conventional composite handlingNotably lighter — easier on long spans and on the crew
Fade & stain warranty25–50 years depending on line50-year fade & stain plus a lifetime limited board warranty
LooksStreaked earth tones, matte finishes on newer linesDeep uniform color and the pale coastal palette composite struggles to match
Sustainability story~95% recycled content is the headlineMostly virgin polymer at the core; its green case is the 25+ year service life, not the feedstock
Best forThe value pick tier-for-tier; shaded and temperate yardsPools, coasts, hot climates, light colors, and 25-year owners

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.

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 — 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.
