Azek Decking Pros and Cons

Resistant to Mold and Mildew. Water is a number one cause for wood decking to depreciate, especially when used in pools. Azek decks are made entirely of PVC, making them virtually waterproof, preventing fungal growth. But without proper maintenance, mold can grow on the surface but will never get through the floorboards.

Insects love wood but not PVC material. You do not have to worry about carpenter bees, termites, or woodboring insects snacking on your floorboards.

Holds up to Extreme Weather Conditions. With a uniform and stable make-up, your Azek decking won’t buckle or shrink even under extreme weather conditions.

Remarkable Impact Resistance. Azek decking has a very durable surface that prevents dents and scratches from showing on your decking.

Fade – Resistant. Because of the lack of organic materials, Azek decking will look pristine from its first installation up to its service life. It also offers a 50-year Fade and Stain Resistant Warranty.

Lightweight. The lack of wood components makes handling Azek decking easy. This also means you can use the PVC deck on raised decks without the need to worry about its weight on your structural foundations.

Does not Splinter. Unlike natural wood, the homogenous and stable nature of PVC material means it won’t splinter, making it a safe surface for walking barefooted, especially for your little ones and even pets.

Can be Reused. While it is easy to install, it is also easy to disassemble and reuse in another location. This transferability makes the Azek decking great for renters and constant movers.

Low Maintenance. The surface is not too sensitive to cleaning agents. A soft broom will do the trick, then power hose the surface to get rid of trapped debris. For stubborn stains, the surface should only be cleaned by manufacturer-approved detergents.

Wide Range of Choices. One of the challenges of wood flooring is finding the right color and texture to match your design preference.

With synthetic decks, there are a wide assortment of designs that you can mix and match with your desired outdoor look, and you will easily find a good number of suppliers in your area.

Looks and Feels like Wood. Trex compared to Azek looks and feels like real wood because of the textured surface and recycled wood content.

Scratch Resistant. Trex wins over Azek when it comes to scratch resistance thanks to hard shell coating that can resist scratching, and withstand long-term exposure to extreme weathers.

Comfortable Surface. As it has wood components, the Trex deck will feel comfortable to walk on bare feet, and with an equal and stable framing, you will feel a sturdy yet soft feeling against your floor decking, just like walking on natural wood.

Cannot be Pressure-washed. It is not recommended not to pressure wash your Trex decking is it can damage the decking surface and void the warranty. You can clean your Trex decking with a damp mop and regular sweeping to prevent debris from settling on the surface.

A Challenge to Remove Ice and Snow. Trex durability remains during extreme weather conditions but can be a challenge to remove ice and snow on the floorboards.

Like all composite and plastic decking materials, the fast heating of your floorboards can be problematic since most decks don’t receive much shade for outdoor use.

There are solutions to reduce the heat on your composite decks where the easiest is to place pergolas, awnings, or patio umbrellas that can reduce the exposure of your decks to direct sunlight. You may mist your decks from time to time with water to reduce the heat.

If you live in a sunny location, you might as well choose another material for your decks, or you can apply UV protection and reflective paint that will reflect heat from your floor surface.

Which is Better Azek or Trex Decking?

Azek has a shinier sheen compared to Trex’s more textured look, and each also has a different feel where Trex is softer to walk on.

Azek is lighter since it contains 95% plastic, but Trex will feel colder than Azek when subjected to direct sunlight. Moreover, Azek has a longer warranty period but costs more than Trex decking.

In areas with large temperature fluctuations Trex decking may hold up better. Due to the plastic content in Azek decking it can expand and contract in wide temperature changes.

However, Azek decking may hold up better in moisture prone regions. Trex on the other hand has a greater likelihood of forming moisture which can result in mildew.

So, it boils down to what features you need for your outdoor decking. If you want a more environmentally friendly option that’s more affordable and see a replacement of your decks for the next 20 to 30 years to be inevitable, then Trex is a sound choice.

However, if you want longevity and plan to reuse and move your deck area in the future Azek is a great option.
