When homeowners have decided on composite, the next question is always which brand? Trex, TimberTech, and Fiberon are the three names most people have heard of, and every one of them makes a genuinely good board in 2026. But the three aren't interchangeable — they differ on heat, structure, looks, and warranty in ways that matter, especially at the 5,800–6,200 feet of the south Denver metro, where UV runs about 25% stronger than at sea level. Here's how we actually think about them as the people who install them.
The 30-second version
- Trex — the household name. Widest availability, the biggest color range in the industry, strong value at the entry tier.
- TimberTech — the premium pick. Best-in-class capping, the deepest realistic wood looks, and a true PVC line (AZEK) that's the most weatherproof of the group.
- Fiberon — the value play. Genuinely good boards, often a little less money than the equivalent Trex or TimberTech line.
Installed, all three land in the same $40–70 per square foot capped-composite range; AZEK PVC runs $50–85. The board line moves you within the range — entry lines keep a build near the bottom, flagship and PVC push toward the top.
The lineup at a glance
Board cost is boards only — substructure, railing, and labor sit on top (all-in materials run ~$20–30/sq ft, labor adds $15–35).
| Line | Type | Boards alone / sq ft | Fade & stain | Structural | Labor coverage |
|---|---|---|---|---|---|
| Trex Enhance Naturals | Capped composite | $6–8 | 25 yr | 25 yr | First 10 yrs |
| Trex Transcend / Lineage | Capped composite | $9–13 | 50 yr | 50 yr | First 10 yrs |
| Trex Signature | Capped composite | $12–15 | 50 yr | 50 yr | First 25 yrs |
| TimberTech EDGE | Capped composite | $6–8 | 30 yr | 30 yr | 5–25 yrs by installer tier |
| TimberTech PRO | Capped composite | $9–13 | 30 yr | 30 yr | 5–25 yrs by installer tier |
| TimberTech AZEK | PVC | $12–16 | 50 yr | Lifetime limited | 5–25 yrs by installer tier |
| Fiberon Good Life | Capped composite | $6–8 | 25 yr | 25 yr | 5–15 yrs by installer tier |
| Fiberon Concordia | Capped composite | $9–13 | 50 yr | Lifetime performance | 5–15 yrs by installer tier |
Heat: the one that matters most in Colorado
With roughly 245 fully sunny days a year and altitude UV, surface temperature is the first thing we think about. A standard dark composite board in direct sun can hit ~160°F on a 90°F day — uncomfortable barefoot and hard on lower-grade caps.
All three brands have addressed this, but not equally:
- TimberTech leads. AZEK's capped polymer and the CoolDeck-technology capstock run 30–35°F cooler than standard dark composite, and the difference is real underfoot.
- Trex answered with Transcend Lineage, engineered to stay cooler than its older dark boards. The entry Enhance line still gets hot in dark colors.
- Fiberon offers cooler-surface options in its premium lines, less consistently across the range.
The rule that beats brand loyalty: color choice alone is worth 10–30°F — a light gray or tan board runs that much cooler than espresso in the same line. On a sunny, unshaded deck, pick a lighter color and a cooler-surface line, whichever brand it's in. A dark standard board bakes no matter whose name is on it.
Structure: capped composite vs. PVC
Two fundamentally different board types hide inside these brands:
- Capped composite (most Trex, TimberTech PRO/EDGE, most Fiberon) is a wood-and-plastic core wrapped in a polymer cap. Excellent for the vast majority of decks.
- PVC (TimberTech AZEK) has no wood content at all — the lightest, most moisture- and heat-resistant board of the group, and the top choice for ground-level, poolside, rooftop, or heavy-freeze-thaw applications. It also costs the most.
For a standard elevated backyard deck, capped composite from any of the three is the right tool. For a low deck close to the ground, or the longest-lived surface money buys, AZEK earns its premium.
Looks
Genuinely subjective, but our general read:
- TimberTech has the most convincing grain and multi-tonal streaking — from six feet, its premium lines pass for stained hardwood.
- Trex has the widest color palette, which matters if you're matching a specific stone, stucco, or trim color.
- Fiberon is often the closest premium look for the money.
Don't choose from a website. Get physical sample boards, set them on your actual deck site, and look at them morning and evening, sun and shade. Color reads completely differently outdoors than on a screen.
Warranty
The table above has the years; two mechanics matter more than the headline number. Labor coverage runs on its own clock — during the labor window the manufacturer pays for replacement boards and the install; after it, boards only. And the long terms are prorated — a claim in year 30 of a 50-year warranty typically reimburses a fraction of the original material cost, materials only. TimberTech and Fiberon tie labor length to the installer's certification tier, so who builds the deck literally changes the paper. The full brand-by-brand math is in our plain-English warranty guide.
On paper the three are close. In practice, a warranty is only as good as the installation — nearly every real-world composite failure we've seen traces to framing, drainage, or fastening, not the board.
The part nobody markets: installation
The brand you pick matters less than who frames the deck. A top-tier board over footings above the frost line (30–36 inches here), oversized joist spacing, or the wrong fasteners will fail long before its warranty runs out — and the manufacturer won't cover framing mistakes. A mid-tier board on a properly engineered, correctly flashed, freeze-thaw-ready structure at 16 inches on center (12 for diagonal layouts) will outlast it easily.
So when comparing bids, spend less energy on Trex-vs-TimberTech and more on the substructure spec, footing depth, and the builder's own labor warranty. That's where decks are won or lost in Colorado. Our composite deck page covers how we frame for this climate.
How we choose on a real project
- Sunny, unshaded, want it cool underfoot? TimberTech premium (AZEK or a CoolDeck capstock line).
- Want a specific color or the broadest palette at a fair price? Trex.
- Great composite deck on a tighter budget? Fiberon.
- Low, ground-level, or poolside deck? TimberTech AZEK PVC.
- Not sure? We're a Deckorators Certified Pro Elite installer, and for many Colorado yards its mineral-based boards — cooler underfoot and more dimensionally stable through big temperature swings — are our actual first recommendation. Worth putting on the sample table alongside the big three.

Bottom line
However you order the matchup, it's decided by the same three questions: how much sun the deck takes, whether the site calls for capped composite or PVC, and what the budget honestly is. Pick TimberTech for premium looks and the coolest, most weatherproof surface; Trex for value and color range; Fiberon for the best composite dollar-for-dollar. Then — more importantly — pick a builder who frames it for Colorado.
