When searching for the ideal deck for your own yard, you may have come across two types of composite decking boards: capped and uncapped. For most homeowners, both types of composite decking are high on the list of deck trim materials. However, before making a decision, you should know the difference between them.

The primary distinctions between these two kind of composite decking will be discussed in this article. We will also discuss the advantages of composite wood decking and the reasons they are the greatest option in our opinion.

What Is Uncapped Composite Decking?

Uncapped composite wood boards are the most popular kind of composite decking. They are composed of wood fibers and recyclable plastic materials. Note that both capped and uncapped composite decking are made of the same composite material.

In the manufacturing process of composite decking, recyclable polymers, wood fibers, and other additives are thoroughly mixed together and then they are extruded through an extrusion die. To give these decks a more authentic look and feel, composite decking manufacturers often add a natural grain to the boards that mimic real wood in the process.

Standard composite decks are made of composite material throughout, so the wood fibers may be exposed on the surface of the deck. Even so, this low-maintenance decking material is still popular with many people. In addition, standard composite decks have a more natural wood grain surface.

Even without capping, composite wood decking is robust and long-lasting, with excellent resistance to mold and water. Because of the surface’s three-dimensional wood grain, uncapped composite decking is incredibly non-slip. It is among the greatest options for pool deck construction.

What Is Capped Composite Decking?

The core of both capped and uncapped composite decking is the same. On the other hand, an extra layer of protective polymer shell envelops it. This polymer shell encases the composite decking on all four sides and ends. By doing this, water is kept out of the decking’s core.

Of the two types of composite decking, capped composite decking is the most durable. This is because the polymer shell is completely waterproof and mold-resistant, which protects the composite material inside. This means that capped composite decking is more robust and durable.

Due to its many benefits, capped composite decking is currently the most popular decking material. Capped composite decking is available in a wide range of designs. COOWIN’s composite decking features artistic color tones and 3D wood grain finishes. These low-maintenance decks have a realistic wood look.

Which Composite Deck Is Better??

Many of the advantages of capped composite decking are also present in uncapped composite decking. But it also offers a few other advantages.

When building a composite deck, the deck’s lifespan and attractiveness should be your top priorities. In light of this, let’s examine the reasons why capped composite decking might be the ideal option for your project.

Look

The exposed wood fibers in uncapped composite decking give it the appearance of a traditional wood deck, and it looks fantastic. Some homeowners prefer this composite wood decking for their outdoor spaces. This is because it avoids the constant upkeep and maintenance that wood decks require, while still providing the natural look of wood.

Capped composite decking has a more flexible appearance and is available in a greater range of colors and styles. This implies that while creating decking, you have additional choices. Finding styles and color schemes that complement your house and yard should be simpler for you.

because of the polymer protective shell’s flat surface. Capped composite decking appears more elegant and refined as a result.

Your personal preference will eventually determine which kind of decking you prefer. Both capped and uncapped composite decks are attractive to look at, and they can both provide a better outdoor living experience.

Maintenance

There is not much of a difference between uncapped and capped composite decking in terms of upkeep. None of them will fade over time, and you won’t need to have them regularly restored, painted, or sealed. This is because both types of composite decking are made from the same material.

The two varieties of composite decking materials require little upkeep other than the occasional cleaning. Strong detergent or warm, soapy water with a soft-bristle brush can be used for cleaning. For the most part, cleaning composite decking—both capped and uncapped—only has to be done every six months.

Compared to capped composite decking, uncapped composite decking has a slightly higher porosity. There isn’t any other distinction between the two. This implies that over time, uncapped composite decking will absorb a tiny quantity of water.

A small quantity of mold or bacterial development could result from this circumstance. These decking boards will require more frequent cleaning if this is the case.

Although it is improbable, the growth of mold or algae on uncapped composite decking would not compromise its durability.

Life of Service

Composite decking is made from a blend of recycled plastic, wood, and other additives. These materials give it excellent resistance to mold, corrosion, and water. In this respect, solid wood decks are not as practical as composite decks. This is because solid wood can absorb water then mold and rot if not properly maintained.

Because composite decking is so sturdy and long-lasting, both capped and uncapped varieties will endure for a very long period. A high-quality composite wood deck should last at least 25 to 30 years.

Conversely, capped composite decking is more waterproof due to an additional layer of protection. It typically outlasts uncapped composite decking as a result.

Stain Resistance

High-quality composite decking materials have excellent stain resistance, so you can’t change its color by painting it. Even more stain resistance is added to the capped composite decking by the protective polymer shell. Spills on capped composite decking stay on top of the decking boards and are easily cleaned off due to the additional polymer covering.

This significantly lessens the possibility that the composite deck boards will become discolored. Furthermore, most liquids that get on the decking just flow off.

This is especially helpful if you plan to surround the pool with composite decking. This is because a liquid (such as sunscreen) falling onto the deck will not change its color.

Uncapped composite decking is more prone to discolor because it lacks a polymer covering. This increases the likelihood that the deck will be stained. If the spill falls on the deck for too long, it may cause discoloration of the deck surface.

However, discoloration won’t be an issue if the liquid is removed from the composite decking’s surface as soon as possible. Comparing uncapped composite decking to other materials like wood decking, it still has exceptional stain resistance.

Cost

The fact that capped composite decking is more expensive than uncapped composite decking may not surprise you. Capped composite decking is worth the extra money for the reasons we mentioned above.

For example, capped composite decking lasts longer and requires fewer repairs or replacements over its lifetime. This means that you don’t have to spend much to maintain it. If you are looking to sell your home, a low-maintenance composite deck can increase the resale value of your home.

This is because most people think that composite decking with caps is of higher quality than decking without caps. This could raise the price at which purchasers value your house.

Availability

Uncapped composite decking is superior to capped composite decking in part because it is more readily available. Capped composite decking is popular with many homeowners. In addition, it is much more expensive to manufacture. As a result, capped composite decking may be harder to buy than standard composite decking.

Generally speaking, the lead time for buying capped composite decking is a little bit longer. However, this will vary on the seller you select. Dealing with this issue is not tough for most people.

However, if you have to build your deck as soon as possible, then choosing a capped composite deck may not be appropriate. This is because it will most likely extend the duration of the deck project.

Capped composite decking is worth the extra time since it offers greater benefits.

Commonly Asked Questions

Is Composite Decking Paintable?

If you would like, you can color your composite decking. If you choose to paint, it’s recommended to start with a primer and work your way up to acrylic paint. We do not advise painting the composite decking, nevertheless. This is due to the fact that it is not required and won’t increase the decking’s durability or lifespan.

Does Capped Composite Decking Require Cleaning With a Cleaner?

The best ways to clean them are with a power washer or warm water and soap. Stains on composite decking surfaces can be removed with a solution of acetic acid, baking soda, and water.

But capped composite decking doesn’t usually look stained, so you might not even need to do this.
