What Does Capped Composite Decking Mean?

Composite decking is a great alternative to traditional wood decking. This decorative material is made from a mixture of recycled plastic and wood. In other words, composite decking boards, including options like boardwalk decking, have the many benefits of both wood and plastic. So, what is capped composite decking?

The first generation of composite decking was made entirely of composite material. With the advancement of science and technology and continuous innovation, capped composite decking has emerged on the market. Unlike standard composite decking, capped composite decking has a protective plastic shell. This plastic shell not only makes the composite decking more resistant to mold, stains, and fading, but it also makes the decking look like real wood, perfect for a deck garden setting.

Capped composite decking is safe, maintenance-free, and long-lasting. These high-performance capped composite decking products are very popular among those who want the look of a wood deck without maintenance, similar to the allure of a composite fence which requires little upkeep.

The Origin of Capped Composite Decking

Wood has been the most popular decking material for many years, and in the early 1990s, composite decking began to appear. Composite decking materials, integral to both boardwalk decking and deck gardens, are made from recycled plastics and wood fibers. This means that using this decking material is good for the environment and helps to solve the problem of cutting down trees. Homeowners can add decking to their homes without having to increase their need for wood.

As more and more people use composite decking, problems are starting to show up. Until about 2010, older composite decking did not have a coating or cover. This meant that water could seep into the decking, leading to mold growth. As a result, early composite decking did not last very long. Composite decking boards also faded quickly when exposed to sunlight for long periods of time.

Later, some manufacturers solved these problems by adding a protective layer to composite decking boards. Since 2010, most types of composite decking have utilized capping technology. These plastic enclosures give composite decking an even better ability to adapt to the environment, much like a composite fence provides enhanced durability and aesthetics.

Advantages of Capped Composite Decking

The “capped” in “capped composite material” refers to the cover that protects the composite decking material. This protective cover protects the boards, thus solving the problems associated with older composite decking.

By capping composite decking, it will not mold, crack, or peel. In addition, because composite decking boards are so thick, termites and other insects can’t chew through them and therefore can’t get into the deck. Capping also prevents the composite decking material from fading or staining.

Capped composite decking does not require the finishing or maintenance of sanding, painting, staining, and sealing that wood decks do. And these decking products are stronger and more durable than solid wood. This is because the capping process protects the composite material better.

On the other hand, once you’ve completed the installation of capped composite decking, you won’t have to spend time or money maintaining the deck. And capped composite decking lasts much longer than any wood deck. This makes it a great choice for decorating your outdoor living space.

Common Composite Decking Brands

Trex is the largest manufacturer of composite decking. They produce more composite decking products than any other company. Trex was the first company to produce composite decking material, founded in the 1990s. Trex composite decking uses a very large amount of recycled plastic bags, which contributes a lot to preserving the living environment.

TimberTech, EVODEK, and Fiberon are other well-known companies that manufacture composite decking. These composite decking manufacturers also produce capped composite decking in a variety of colors and textures, just like Trex. If necessary, you can learn more about the advantages and disadvantages of each brand of composite decking, and then choose the right composite decking for your situation. Why Capped Composite Decking?

Why Is Capped Composite Decking a Good Choice?

Many types of materials can be used to build a new deck. You can choose from pressure-treated lumber, cedar, azuki or mahogany, PVC, or composite decking. Although there are many decking materials available on the market today, capped composite decking is still the best choice for a number of reasons.

It Doesn’t Require Much Maintenance

Traditional wood decking requires regular maintenance regardless of the type of wood used. One way to do this is to power wash and sand the entire deck and then stain or paint each board, railing, and spindle. This depends on the type of wood, but for most types of wood, it needs to be done at least every two or three years, if not every year.

Capped composite decking does not require these regular maintenance and upkeep tasks. So you can enjoy your deck without having to worry about it. The fasteners on your composite decking won’t pop or crack, and old paint or stains won’t flake off.

When you build an outdoor living space with capped composite decking, the only “maintenance” you’ll need to do is to give it a quick rinse with the yard hose when leaves or pollen fall on the deck. If you drop wine or food scraps on your deck during your daily outdoor get-togethers. That’s okay, just clean it with mild soapy water.

No Long-Term Costs

Traditional wooden decks require regular maintenance, which is not only a hassle but also expensive to maintain over time. Capped composite decking costs a little more to build than regular wooden decks. However, this type of decking does not require regular maintenance once it is installed.

Many homeowners with composite decking feel that the money they spend upfront is worth it. This is because the completed composite decking does not require the regular maintenance that wood decks do. At first, it may be tempting to purchase a cheaper wood deck, but after a few years of use, composite decking pays for itself.

Resistant to Environmental Stress

Because capped composite decking has a strong and secure protective cover. So it won’t be damaged by the elements like wood decking. Capped composite decking won’t crack, peel, or splinter because the polymer shell is waterproof and mold-resistant. Because the composite decking material is so dense, termites and other bugs can’t get in either.

In addition, the polymer shell protects the surface of the composite decking material. So these decking materials won’t fade or warp in the sun or rain. They also don’t stain or scratch easily, so your deck will look new for years. Of course, you also need to be careful if you move furniture around on top of your deck. Heavy or sharp furniture can also scratch the surface of composite decking.

Summary

Building a capped composite decking for your patio can return a higher value. When selling a home, most people choose a home with a capped composite decking over a regular wooden deck. In addition, the surface of composite decking looks like real wood and will last 25 years or more without any regular maintenance.

Composite decking material is also a good choice for the environment because it does not require cutting down trees. If you choose capped composite decking to build your new deck, it will save you time and money on maintenance later on, and it will still look new for years.

Over the years, composite decking has changed so much that it now looks almost exactly like real wood. Capped composite decking comes in a wide variety of colors, styles, and grain patterns that look just like solid wood that has been stained or painted. With composite decking, you can build the deck of your dreams and not have to worry about maintenance for decades.
