AZEK Decking: The Nerdy Details Your Dad May Want To Know



Fellow deck enthusiasts: here at Deck Bros, we've seen our fair share of decking materials come and go. But let me tell you, AZEK decking is something special. If you're looking to upgrade your outdoor space, you'll want to stick around and learn why AZEK might just be the perfect choice for your new deck.


What Exactly is AZEK Decking?


AZEK decking, my friends, is the crème de la crème of engineered decking materials. It's a type of PVC (polyvinyl chloride) decking that's designed to look and feel like real wood, without all the maintenance headaches that come with traditional timber.


Now, I know what you're thinking – "PVC? Isn't that the stuff they make pipes out of?" Well, yes, but AZEK has taken this versatile material and engineered it into something truly remarkable for outdoor living spaces.


The Science Behind AZEK


Let's get a bit technical for a moment (don't worry, I'll keep it interesting!). AZEK decking is made through a process called cellular PVC extrusion. Basically, they take PVC material and foam it up with tiny air bubbles, creating a cellular structure that's lightweight yet incredibly strong.


This cellular PVC is then extruded (fancy word for "shaped") into decking boards that mimic the look and texture of real wood grain. The result? A decking material that's:


1. Incredibly durable

2. Resistant to moisture, mold, and mildew

3. Impervious to insect damage

4. UV-stable (meaning it won't fade in the sun)

5. Scratch and stain-resistant


But that's just scratching the surface. Let's dive deeper into the physical properties that make AZEK decking stand out from the crowd.


Density and Weight: The Goldilocks of Decking


AZEK decking hits the sweet spot when it comes to density and weight. It's lighter than traditional hardwoods like ipe or cumaru, making it easier to handle during installation. But don't let that fool you – it's still dense enough to feel solid underfoot and withstand heavy furniture or foot traffic.


The cellular structure I mentioned earlier? That's what gives AZEK its unique density profile. It's about 10% less dense than solid PVC, which translates to a weight of around 2.5 pounds per linear foot for a standard 5.5-inch wide board. This makes it lighter than most composite decking options, yet still hefty enough to feel substantial.


Thermal Properties: Keep Your Cool


One of the coolest things about AZEK decking (pun intended) is its thermal properties. Unlike traditional wood or composite decking that can get hot enough to fry an egg on a sunny day, AZEK stays relatively cool to the touch.


The secret lies in its cellular structure and the engineered cap layer. These features work together to reflect more heat and absorb less, keeping your deck comfortable even on the hottest summer days. So go ahead, kick off those flip-flops and enjoy your deck barefoot!


Moisture Resistance: Say Goodbye to Water Worries


Water is the enemy of most decking materials, but AZEK laughs in the face of moisture. Its closed-cell structure means there's nowhere for water to penetrate or accumulate. This gives AZEK decking some impressive stats:


- Water absorption: Less than 0.25% by weight

- Moisture content: Virtually zero


What does this mean for you? No swelling, warping, or rotting, even in the wettest conditions. You can install AZEK around pools, in rainy climates, or even use it for dock applications without worry.


Strength and Flexibility: Bend, Don't Break


AZEK decking boasts an impressive strength-to-weight ratio. It has a flexural strength of around 3,600 psi (pounds per square inch), which is comparable to many hardwoods. This means it can span longer distances between supports without sagging – great news if you're dreaming of a spacious, open deck design.


But here's where it gets really interesting: AZEK has a unique combination of strength and flexibility. It has a flexural modulus (a measure of stiffness) of about 430,000 psi. This is lower than some hardwoods, which might sound like a downside, but it's actually a clever design feature.


This slight flexibility allows AZEK to absorb impact better than rigid materials, reducing the risk of cracking or chipping. It also makes the decking more forgiving on slightly uneven surfaces, and more comfortable underfoot.


Fire Resistance: Safety First


While no decking material is completely fireproof, AZEK takes fire safety seriously. It has a Class C fire rating, which means it has a moderate resistance to fire spread. In practical terms, it won't ignite easily and will burn more slowly than natural wood if exposed to flame.


AZEK decking also doesn't produce toxic smoke when burned, unlike some other synthetic decking materials. This is an important safety consideration, especially for families with young children or pets.


UV Stability: Fade? What Fade?


We've all seen those sad, gray wooden decks that have been battered by the sun. AZEK says "no thank you" to that kind of aging. Its engineered cap layer includes UV inhibitors and color stabilizers that keep your deck looking fresh for years.


How effective is this UV protection? Well, AZEK backs it up with a 50-year fade and stain warranty. That's half a century of color retention, folks!


Chemical Resistance: Spill-Proof Your Outdoor Life


Life happens, and sometimes that means spills on your deck. Whether it's your famous BBQ sauce or little Timmy's grape juice, AZEK has got you covered. Its non-porous surface resists staining from a wide range of substances, including:


- Food and beverages

- Sunscreen and bug spray

- Household cleaners

- Pool chemicals


Most spills can be cleaned up with just soap and water, no harsh chemicals or scrubbing required. This resistance to chemicals also means you can use a wider range of cleaning products without worrying about damaging your deck.


Environmental Impact: Green in More Ways Than One


Now, I know what some of you eco-conscious homeowners might be thinking: "Isn't PVC bad for the environment?" It's a fair question, and one that AZEK has put a lot of thought into.


While it's true that PVC isn't biodegradable, AZEK decking is designed to last for decades, reducing the need for replacement and the associated resource consumption. Plus, it's 100% recyclable at the end of its (very long) life.


AZEK also uses a closed-loop water recycling system in their manufacturing process, and their products are made with up to 54% recycled materials. They've even achieved GreenCircle certification for recycled content and waste diversion.


Installation and Maintenance: A DIYer's Dream


As a deck builder, I appreciate how easy AZEK is to work with. It can be cut, drilled, and fastened with standard woodworking tools, making installation a breeze. For you DIY enthusiasts out there, this means you could potentially tackle the project yourself (though I'd still recommend hiring a pro for best results!).


Maintenance? What maintenance? AZEK doesn't need to be sanded, stained, or sealed – ever. A simple cleaning with soap and water once or twice a year is all it takes to keep your deck looking fantastic.


The Bottom Line: Is AZEK Right for You?


After all this tech talk, you might be wondering: "Sounds great, but is it worth it?" Well, that depends on what you're looking for in a deck.


If you want a low-maintenance, long-lasting deck that looks great year after year, AZEK is hard to beat. Yes, it's more expensive upfront than pressure-treated lumber or some composite options. But when you factor in the lack of ongoing maintenance costs and its incredible longevity, AZEK often comes out ahead in the long run.


Plus, let's not forget the peace of mind that comes with knowing your deck will look great and perform well for decades to come. No more worrying about splinters, rotting boards, or faded, sad-looking decks.


In our experience, AZEK is particularly well-suited for:


- Busy families who don't have time for regular deck maintenance

- Homes in harsh climates (hot sun, lots of rain, or near saltwater)

- Anyone who wants a truly long-term decking solution

- Homeowners who appreciate the look of wood but want better performance


So there you have it, folks – a deep dive into the world of AZEK decking. It's a material that combines the best of modern technology with the timeless appeal of a beautiful outdoor living space. Whether you're building a new deck or replacing an old one, AZEK is definitely worth considering.


Remember, your deck is more than just a place to put your grill – it's an extension of your home, a place for making memories with family and friends. Choose a decking material that will provide the perfect backdrop for those memories for years to come.
