What Is Composite Decking

First things first, let’s see what exactly is composite decking and how it’s made.

Composite decking is a mix of plastic film and wood fibers pressed together under extreme heat to create a strong and resilient material.

The plastic film that goes into composite decking can include polypropylene or polyethylene, and it works well with wood fibers to create this high-quality material, superior to plastic decking or wood decking.

Note: Composite decking must not be confused with PVC decking, which is made completely from synthetic materials. It has polyvinyl chloride, a type of vinyl typically used for outdoor siding and fencing.

While composite decking is known for its durability, a few common issues can arise.

These include color fading over time due to UV exposure, potential mold or mildew growth in damp environments, and the risk of surface scratches or scuffs.

However, high-quality composite decking brands often incorporate protective coatings and technologies to mitigate these problems.

The lifespan of composite decking varies depending on factors like the quality of the materials, maintenance, climate, and usage.

Generally, well-maintained composite decks can last anywhere from 25 to 30 years or more.

Choosing a reputable brand and following manufacturer-recommended care and maintenance guidelines can help maximize the lifespan of your composite deck.

Trex is a well-known brand of composite decking. Like all composite materials, Trex decking is designed to be more resistant to sagging compared to traditional wood.

However, sagging can still occur if the deck’s substructure isn’t properly constructed or if the manufacturer’s installation guidelines aren’t followed.

To prevent sagging, ensure proper spacing between joists, use adequate support beams, and follow the manufacturer’s recommendations for installation and weight distribution.


Composite decking pros and cons shouldn’t stop you from looking deeper into it. Overall, composite is a great alternative to a wood deck that’ll surely make your deck addition more functional.
