TimberTech vs Trex: Why Better Tech, Better Deck Matters

May 19, 2021

When it comes to the composite decking market, we know we go head-to-head with Trex. And we know that, before you choose the right composite decking product for you, it’s important to compare TimberTech vs Trex across the categories that matter to you the most:

So, we’ve done just that. May the best brand win.

TimberTech vs Trex: A Very Brief Background


The first-to-market brand in the composite decking space, Trex formed in 1996 and went public in 1999 with then-revolutionary composite decking products. And while the brand may have initially cornered the composite decking market, first-mover advantage seems to have led innovation to stall out: Trex’s last “game changer,” Trex Transcend decking, is over a decade old.


TimberTech entered the market in 1997 and introduced capped composite deck boards in 2008. We continued to innovate so that you have your choice of not only premium capped composite decking, but premium capped polymer options via TimberTech AZEK® decking as well. Even better news? We’re just getting started.

We believe in the truism Better Tech, Better Deck™ — especially when you’re investing in an enduringly beautiful outdoor living space that can increase the overall value of your home.

Just because a brand was first to market doesn’t mean its offering is the best — after all, Apple was once a challenger brand to Microsoft.

Let us be your guide.

TimberTech vs Trex: Materials Science & Board Composition

What is composite decking? In the alternative decking marketplace, “composite decking” is the umbrella term for engineered decking — meaning alternatives to wood. That said, there are a few important product line distinctions within that larger category:

Capped Composite Deck Boards

Made from a blend of wood fibers (organic material) and plastics/polymers (synthetic material).

Capped Polymer Deck Boards

Made from 100% plastics / polymers (synthetic material).

Why This Matters

Capped polymer deck boards offer unique advantages. The capped polymer decking of our TimberTech AZEK line:

✓ Offers unrivaled design and performance.

✓ Offers superior moisture resistance — that means mold, mildew, and other erosion agents that eat away at your deck don’t stand a chance.

✓ Is backed by a 50-Year Limited Fade & Stain Warranty.

✓ Stays cooler to the touch.

✓ Boasts advanced design options including Multi-Width.

If you want to compare to Trex — well, you can’t. Trex doesn’t offer any capped polymer decking products.

That means, if you’re looking for the highest-performing and longest-lasting deck made from the most forward-thinking technology, you can’t find it with Trex.

Why 4-Sided Capping Matters

First things first: Trex doesn’t cap all 4 sides of the deck board on any of their decking lines. Why? Purportedly, because there is a belief that moisture will inevitably invade the boards and therefore needs the chance to evaporate out.

The thing is, that’s kind of like saying you have a security system wired to protect 75% of your home because “a burglar will get in eventually.” The real way to minimize the chance of an unwanted visitor is to protect the entirety of your investment.

We offer premium composite decking with capping all the way around the board: TimberTech PRO® decking

Mold and mildew are the ultimate erosion agents when it comes to decking. By applying protection at all exposure points on the board, or by offering a synthetic product like TimberTech AZEK, we can proudly say it’s not just the “same mold, same mold” with TimberTech decking.

4-sided capping means you protect 100% of your investment, which you can’t do with Trex. When you compare TimberTech vs Trex, there’s no comparison.

TimberTech vs Trex: Nature-Inspired Beauty

One of the main reasons homeowners sometimes pause when considering a shift from wood to composite decking — no matter the brand — is the fear that composite deck boards look “fake” or “plastic-like.” Let’s see how true that concern is in terms of TimberTech vs Trex.

Trex: Less Realistic Colors, Deeper Grains

Less Realistic Color Choices

Trex boards don’t showcase the advanced technology that allows for realistic, varied color-blending. When you closely examine some Trex boards, you can also see exposed wood flakes that emphasize its synthetic quality.

Realistic grain patterns with TimberTech

Unnatural-Looking Grain

Trex boards are marked by deep-cut cathedral grain patterns that emphasize the synthetic quality of the material. Highly sought-after hardwoods are defined by complex, varied grain patterns, so Trex boards fail to capture the nuanced beauty of real wood.

Trex boards look like plastic — shiny, deeply grooved, and without the nuanced color-blending and artisanal touches that define a TimberTech deck board.

TimberTech: All the Nuanced Beauty of Wood, None of the Hassle

TimberTech boards are designed and engineered to capture the color-blending and richness of natural wood. This is truly where “timber” meets “tech”: Using advanced materials technology and proprietary polymer blends, TimberTech deck boards offer you:

TimberTech vs Trex: Durability & Performance

This is big. After all, you want your investments to work as hard for you as you worked for them.

Trex claims unmatched warranty coverage in the industry — but we think you should see the true comparison.

So, Trex claims unmatched warranties…and we’d agree. We don’t just match Trex warranties. We double the coverage — and then some.*

*TimberTech AZEK decking includes a Lifetime Limited Product Warranty

If you find yourself thinking: “That sounds good, but just what are those warranties backing up?” The answer is: unparalleled performance. Neither Trex nor Mother Nature has an edge on us.

TimberTech vs Trex: Exposure Tests*

Highly reputable accredited third-party lab conducted testing per ASTM D2244 and ASTMG154 standard on material purchased from consumer channels. Study tested for the following: Color measurement process reports dE based on the CIELab color space using D65 illuminant at a 10-degree angle. Samples tested in weatherometer chamber for a total of 2,150 hours; subjected to cycles of 8 hours of UV radiation followed by 4 hours of darkness to ASTM specs.

TimberTech deck boards can stand up to UV ray exposure, so your deck stays looking as beautiful on day 1,000 as on day 1.

TimberTech vs Trex: Value for the Cost

We know that, in terms of upfront costs, you will likely make a greater investment with a TimberTech deck (however, if you’re looking for an attractive and attainable entry-level product, we also offer TimberTech EDGE decking). But when you think about the cost to build a deck, it’s important to consider not just upfront, but long-term costs.

How Trex Saves You Money Upfront… But Can Cost You Long-Term

With Trex, all deck boards feature only 3-sided capping. That translates to lower materials cost compared to 4-sided or fully synthetic boards, and therefore a lower cost-per-board.

But there’s a catch: 3-sided capping doesn’t minimize the risk of mold or mildew growth, so you could face a shorter deck lifespan with a Trex deck than you would with a fully synthetic TimberTech AZEK deck.

TimberTech Decking Means Long-Term Cost Savings

With our composite decking, over 30 years, your deck can pay for itself. How? By continuing to perform at the same level as when it was first installed. That means the long-term costs associated with maintaining a traditional wood deck won’t apply, so you’ll keep money in your wallet that would have otherwise gone to repair and replacement.

But what about when comparing TimberTech vs Trex?

When it comes to composite decking, one of the best ways to assess value for the cost isn’t by zeroing in on upfront material prices. Rather, value for the cost means locking in long-term performance. And the best way to compare performance is to compare warranty coverage.

TimberTech vs Trex: Value for the Cost

TimberTech vs Trex Value for the Cost

As you can see, Trex products stay only at the industry average of 25-year coverage. TimberTech on the other hand? A much different story.

With warranties like a Lifetime Limited Product Warranty and 50-Year Fade & Stain Warranty, a TimberTech deck translates to serious time-, cost-, and back-saving benefits over the years.

Remember: There are a number of factors that go into calculating the overall costs associated with your deck, and material cost is just one. Make sure you’re familiar with all the factors as you research the right decking for you.
