Why Seek the Most Sustainable Decking Material?

Reasons to seek the most sustainable decking material

Choosing a sustainable deck material isn’t just a great choice for the planet — it’s a great choice for you and your family, too.

Benefits of Choosing a Sustainable Deck Material


Contributes to your home’s eligibility for LEED certification which, in turn, can improve the resale value of your home.

No staining required, so no exposure to the potentially harmful chemicals often found in wood deck stains.

Helps contribute to a healthier planet for your family and future generations.

Less maintenance needs thanks to longer-lasting materials, which translates to less material making its way to landfills — and lower long-term costs, too.

Now that you know the benefits of choosing a sustainable deck material, it’s time to explore your options.

A Brief Look at Your Deck Material Options

Your deck material options include different types of traditional wood as well as engineered decking alternatives like TimberTech® capped polymer and capped composite decking. Your options vary significantly in terms of performance, aesthetics, cost, and of course, which is the most sustainable decking material.

Organic Wood? A Natural Disaster

Before we go further, it’s worth pausing to acknowledge a common misconception. You might think that natural wood decking is inherently the most sustainable decking material — more so than manufactured alternatives.

The thinking goes: Given that wood comes from nature, sustainability must be primarily associated with natural wood. Right? Wrong.

That’s actually the very reason why organic options are not as sustainable as engineered decking. Cutting down trees for decks often contributes to deforestation, and using chemicals to maintain the performance or appearance of natural wood releases Volatile Organic Compounds (VOCs) into the air and even the ground beneath your home. All this makes wood far from your most sustainable decking material.

Traditional wood is not the most sustainable decking material

Wood Maintenance: An Unsustainable Chore

Left untreated, wood is highly vulnerable to the elements, especially moisture.

The only way to protect it? Regular (and costly) staining, oiling, and/or sealing for protection — which means lots of exposure to VOCs over the lifespan of your deck.

So What Makes Composite Decking a Sustainable Deck Material?

One of the most sustainable decking material options is composite decking

A sustainable deck material is one that:

Uses majority recycled material.

Doesn’t require harmful chemicals for maintenance.

✓ Is made with sustainable manufacturing processes

Promoting better health for your family and the planet.

Your sustainable choice? TimberTech capped polymer and capped composite decking.

At TimberTech, we believe you deserve a better life outdoors, which is why we strive to deliver the best of the best. That means the most beautiful outdoor living products built on a foundation of innovative tech and sustainability. Because you deserve products that not only look good, but do good.

Decking Made From Majority Recycled Material

At TimberTech, we turn plastic scrap and discarded wood fibers into beautiful recycled decking products. Whether you choose capped polymer or capped composite, you can be sure you’re choosing a sustainable alternative to traditional wood.

The most sustainable decking material is one made of a majority recycled material

TimberTech Capped Polymer Decking

TimberTech® AZEK® capped polymer decking is made of approximately 50% recycled material, including hard-to-recycle plastics.

The most sustainable decking material is capped composite decking

TimberTech Capped Composite Decking

TimberTech PRO® and TimberTech EDGE® capped composite decking is made of approximately 80% recycled material, including 100% recycled wood fibers.

Choosing recycled decking material reduces the amount of virgin lumber being used in deck building. This in turn reduces deforestation and keeps millions of pounds of waste out of landfills each year. In short? Recycled decking material supports a more sustainable future.

With TimberTech, your deck ideal can be real. Our decking is designed with nature-inspired, saturated hues that endure, come rain or shine. And to maintain them? Forget spending several hours and hundreds of dollars sanding, staining, and sealing your deck. With TimberTech, maintenance is a simple matter of cleaning and rinsing.

Sustainable Manufacturing Processes

Using recycled materials that support eco-friendly maintenance wouldn’t mean much if the way those materials were made wasn’t sustainable, too. Luckily, TimberTech decking is made with sustainable processes that use our resources responsibly, so future generations can have the same quality of life we do.  

How It Started

The most sustainable decking material is one that is made from hard to recycle plastics

First, we source post-consumer and post-industrial plastics.

Next, we transfer our raw materials to our in-house, state-of-the-art recycling facilities.

Then, the magic happens.

Our team of expert engineers, researchers, and innovators transform these recycled materials into the highest-quality outdoor living products.

Because we refuse to settle for anything inferior.

How It’s Going

The most sustainable decking material is one that is made with sustainable manufacturing processes

Nearly 3 million trees

saved from being cut down since 2001.

Approximately 500 million lbs.

of scrap and waste diverted from landfills in 2021.

Up to 97% of water

recycled annually in our closed-loop water filtration system.
