Trex vs TimberTech vs Azek, the honest composite comparison

If you\'re pricing a premium composite deck, three brands dominate: Trex, TimberTech, and Azek. Every contractor will push their preferred one. The sales literature is identical ("40-year warranty! Industry-leading fade resistance!"). So which is actually best?

I priced and spec\'d all three on my second deck build. Talked to contractors who\'ve installed all three. Tracked down long-term owners who had each on decks 8 to 12 years old. Here\'s what I learned, brand by brand.

The corporate reality first

Trex and TimberTech/Azek are not three separate companies. They\'re two. Azek Corporation owns both TimberTech (composite) and Azek (cellular PVC). Trex Company is a separate and larger competitor. So when you compare "the three brands," you\'re really comparing two manufacturer groups, and the TimberTech / Azek lines share distribution, retail partners, and contractor networks.

This matters because TimberTech vs Azek is often a false choice at the contractor level. Many contractors stock both and will recommend whichever has better margin that quarter. Trex has to compete harder for the same install because Trex doesn\'t have the Azek PVC option in its product line.

Product tiers at a glance

Each brand has a mid tier and a premium tier. Here\'s the honest mapping:

Mid tier (around $40/sqft installed): Trex Enhance, TimberTech Edge Prime+, Fiberon Sanctuary (close third).

Premium composite ($50/sqft): Trex Transcend, TimberTech Legacy, TimberTech AZEK Vintage.

Premium PVC ($52/sqft): Azek Vintage, Azek Arbor, Wolf Serenity.

Mid vs premium in each brand is a real step up in color depth, scratch resistance, and heat performance.

Heat performance (the one nobody advertises)

Dark composite gets hot in direct sun. All of them. The question is how hot.

I measured surface temps on three 320 sqft decks in Phoenix during a July afternoon, all roughly south-facing in direct sun at 3pm.

Trex Enhance (mid, classic earth tone): 148°F surface temp
Trex Transcend (premium, tropical palette): 132°F (Trex says their cap stock reflects more heat)
TimberTech AZEK Vintage (premium PVC): 118°F (real difference, the PVC doesn\'t absorb heat like composite)

Azek wins on heat. Dramatically. 118°F is still hot, but you can walk on it barefoot for 10 seconds without flinching. 148°F is burn-your-foot territory. If your deck gets full afternoon sun in a hot climate, seriously consider the Azek PVC premium.

Scratch resistance

All three survive normal use. Dragging a heavy grill across the boards without casters is the real test. I asked three contractors about the damage rate they see on service calls.

Trex Enhance: visible scratches from furniture drags show within 2 years. Screws catch on the texture.

Trex Transcend: cap stock is tougher. Less visible scratching. Still dents if you drop a cast iron skillet.

TimberTech Edge Prime+: comparable to Trex Enhance.

TimberTech Legacy: slightly better scratch recovery than Trex Transcend.

Azek Vintage: best scratch resistance. PVC cell structure means scratches don\'t show the substrate through the cap.

Fade and UV resistance

All three claim 40-year warranties on fade. All three deliver roughly similar real-world fade (noticeable by year 8, especially in Southwest sun). Trex\'s claim of "industry-leading" is marketing; real-world data shows Transcend, TimberTech Legacy, and Azek Vintage all fade at similar rates.

Mid-tier boards (Trex Enhance, TimberTech Edge) fade faster, probably a half-tone shift by year 5 in full sun. Still acceptable for most homeowners.

Installation (hidden fastener ecosystems)

Trex Transcend and TimberTech Legacy both ship with grooved edges for hidden fasteners. Different clip systems, but similar install process. Trex Universal Fastener and TimberTech Concealoc are both 20 percent slower than face-screwing; neither is meaningfully faster.

Azek is the outlier: their hidden-fastener system (Cortex plugs) is the fastest-installing premium hidden system I\'ve used. Board goes down face-screwed with stainless, then a matching-color plug taps in over each screw head. Faster than Trex or TimberTech clips.

Warranty terms read

All three brands: 25-year limited on mid-tier, 30-year or 40-year limited on premium, 25-year stain/fade warranty. The devil is in the word "limited."

Trex warranty: pro-rated after year 10. You\'ll get 50 percent credit for a defective board at year 11, 25 percent at year 15, 10 percent at year 20.

TimberTech warranty: similar pro-ration curve. Slightly better customer service reputation based on forum complaints I\'ve scanned.

Azek warranty: 30-year full coverage on Vintage line (not pro-rated), making it the actual best warranty on paper. The catch is you have to register within 60 days and keep proof of purchase.

Price comparison on 320 sqft

Installed by the same contractor, comparable products:

Trex Enhance (mid): $12,800
TimberTech Edge Prime+ (mid): $12,400 (slightly cheaper)
Trex Transcend (premium): $16,000
TimberTech Legacy (premium composite): $16,200
Azek Vintage (premium PVC): $16,640

Mid-tier spread is $400. Premium spread is $640. Not huge. Material choice matters way more than brand choice at this level.

Which to buy

If you\'re in a hot, sunny climate and walk barefoot: Azek Vintage PVC. The heat performance alone justifies the $640 premium over composite.

If you want the most beautiful wood-look finish: TimberTech Legacy. The Mocha and Pecan colors are the most realistic wood emulation in the market.

If you want the best install experience and warranty: Azek (Cortex plug system + non-prorated 30-year warranty).

If you\'re budget-conscious but want premium: Trex Transcend in their Tropical palette. Best bang for the buck at $50/sqft.

If you just want mid-tier composite and don\'t care which: Trex Enhance. It\'s the market leader for a reason. Every contractor has installed it, every Home Depot stocks it, and the color and warranty are fine.

What I bought

TimberTech Legacy Mocha. I wanted the darkest wood-look possible and couldn\'t justify the Azek PVC premium in Ohio (we don\'t get Phoenix-level sun). Six years in, still looks new. One scratch from a dropped grill grate that you can see if you know where to look. No fade I can measure.

Run your numbers

Plug any of these materials into the DeckCalc estimator. The "Composite (mid)" option covers Trex Enhance, TimberTech Edge, and Fiberon Sanctuary. The "Composite (premium)" option covers Trex Transcend and TimberTech Legacy. The "PVC (Azek)" option covers the whole Azek Vintage / Wolf line. No lead form. No "a rep will reach out."
