Composite decking has been around for many years and has evolved immensely. We are advocates of composite decks. But there is no denying that composite decking has some drawbacks. Understanding the disadvantages of composite decking is how you can decide if composite decking is right for your project.
Disadvantages of composite decking
Fading due to sunlight exposure
Composite decking material is known for its durability and longevity, but it doesn't stand up to prolonged sun exposure. Over time, brightly colored decking can begin to fade, resulting in a less than aesthetically pleasing appearance. UV rays from the sun can damage the decking material composition, which can lead to color changes. Some newer composite decks come with UV-resistant coatings, but the color can still fade with prolonged exposure to sunlight. So this is a factor to consider for sunny outdoor spaces.
Can't be painted
Unlike traditional wood decking, composite decking is not suitable for painting or staining. Composites include a mixture of wood fibers, plastics, and adhesives. These materials are treated during the manufacturing process. Therefore the finished product does not need to be repainted. This means that once Composite decking is installed, its color and finish are permanent. Any idea of changing the look or refreshing the color by painting is not feasible.
Warping Occurs
Composite decking can warp and bend in extremely hot weather. This is because the plastic component expands at a different rate than wood fibers at high temperatures, which causes the decking to warp. This problem can lead to an uneven surface of the deck, which affects the aesthetics. In more serious cases, it can also cause a tripping hazard. High-quality composite materials can minimize these effects. However, it is still a factor to consider in environments with wide temperature fluctuations.
Wood frame rot
Composite decking boards are inherently good at resisting rot. However, if they are installed over wood framing, moisture between the wood and the deck can cause the subframe to rot over time. This is especially likely to happen in humid areas. For this reason, it is important to ensure that the bottom frame is treated against moisture and has adequate ventilation to prevent moisture buildup.
Deck Insulation
Composite deck boards dissipate heat more slowly when exposed to prolonged sunlight. This can make it can get hot underfoot, making it more uncomfortable than traditional wood deck boards. The plastic component in composite deck boards absorbs and retains heat. This is a big disadvantage for homeowners who like to relax or play outdoors. Choosing a light-colored deck can alleviate this problem somewhat, though, as lighter colors absorb less heat than darker colors.
Difficult to Repair
Repairing a composite deck is more challenging than repairing a traditional wood deck. Because it is a man-made deck, composite decking cannot be sanded or refinished like wood. If the deck is damaged, the entire deck boards usually need to be replaced. Not only does this cost more, but with ongoing repairs, the color may not match due to fading.
Higher upfront costs
Composite decking boards have a higher initial cost compared to traditional wood decking boards. The manufacturing process for composite decking boards is more complex and resource-intensive. As a result, their purchase price is also higher. However, composite decorative decking can save money in the long run by reducing the need for maintenance. However, the initial investment can be a big hurdle for some homeowners. Thus the long-term benefits must be weighed against the upfront costs.
Limited residual value
Composite decking boards can enhance the beauty and functionality of an outdoor space. However, it does not significantly increase the resale value of a property in the same way that natural wood deck boards do. Part of the reason for this is the personal preferences of potential buyers. Some homeowners may prefer the natural look and feel of wood to composite materials. Therefore, investing in composite decking should be considered more for personal enjoyment than as a financial investment in property value.
Slippery floors
Composite flooring can become slippery when wet. This can therefore pose a safety hazard in the rain or around swimming pools. This is because the smooth surface of the flooring lacks the natural friction provided by traditional wood grains. Manufacturers often address this issue by incorporating textured finishes or non-slip coatings. However, results may vary and some products may still be dangerous in wet conditions. It is important for homeowners to consider the slip resistance of laminate flooring, especially in areas that come in contact with water on a regular basis.
