Composite decks are becoming popular in the UK. Many homeowners are even starting to replace their old wood decks with composites. But before you decide to build on in your backyard, there are several things you need first.
1. Composites Have Many Advantages Over Wood
Composite decking has many advantages over wood. Wood decks are susceptible to several issues, such as fungi growth, rotting, and warping. On the other hand, composites don’t rot. They are also resistant to moisture and weather. While they can still warp and bend, they are more dimensionally stable than most wood decks. In terms of durability, a composite deck can last for at least 20 years, whereas most wood decks, except for hardwoods, last only 10 to 15 years at most.
2. Plastic Decking is Different From Composite Decking
Many confuse composite decks with plastic decking. Plastic decks use thermoplastics such as PVC and HDPE. While composites also have these plastic resins, they do have wooden fibres mixed in. Having wood fibres makes a big difference, both in performance and in aesthetics. Composites are less susceptible to temperature fluctuations and thermal expansion than plastics. Composite decks also look more natural and wood-like.
3. Composite Decks Are More Expensive
If you plan to build a composite deck, expect to spend a little more on materials. On average, most wood decking only cost £3 to £10 per metre, whereas composites can cost anywhere from £4 to £12. The only wood varieties that are more expensive than composites are hardwoods.
4. There are Several Varieties of Composite Decking Boards
Not all composite decking boards are the same. When looking for decking boards, you can find a wide variety of composites. They differ in shape. Some are hollow, while others are solid. Some decking boards have grooves on their sides, while some don’t. You can also find several colours of composite decking boards. You will need to look at their differences and weigh the advantages and disadvantages of each variety.
5. Low-Maintenance Doesn’t Mean No-Maintenance
Many homeowners may make the false assumption that composites don’t require any maintenance. While it is low-maintenance, it does need some upkeep. Fortunately, composite decking doesn’t require as much effort, time, and money to keep it in top condition. Regular sweeping and occasional wash and rinse are all you need to do. You don’t need to stain, paint, or seal a composite deck. Over time, you can save more money on composites due to their low upkeep costs.
6. You Can’t Paint Composites
Paint and composites don’t go well together. Several composite decking brands don’t recommend painting their products. Painting some decking boards may even void their warranties. The only time it is recommended to paint composites is when it starts to fade. However, it will take a few years before that happens. When painting composite decks, you will need to prep them for the surface to accept the paint. Part of the preparation is sanding it, which removes its outer protective layer. For this reason, many are against painting composites.
7. Most Composites Uses Hidden Fasteners
As mentioned, there are several varieties of composite decking boards. Today, most composite boards are grooved. These boards have a notch or indentation on the sides. When using them, you can’t screw or nail the boards like most wood decks. Instead, you will need to use hidden fasteners composed of clips inserted and screwed into the boards’ grooves. In some cases, there are fastener systems specially designed for a specific brand of decking boards.
8. Composite Decking Can Get Hot and Slippery
Because composites have plastics, they are still susceptible to temperature. Like any material, they may get hot fast when exposed to hot weather. However, they are significantly cooler than plastic decks. If the deck getting hot is one of your concerns, you may want to use lighter-coloured decking boards. Light colours reflect light and heat instead of absorbing it. Like wood and plastic, composites can also be slippery when wet. You can use decking tapes, rugs, and carpets to prevent slips and trips. It’s also best to keep the deck dry at all times to minimize accidents.
Is Composite Decking Worth It?
Like any other decking material, composites have advantages and disadvantages. But is it worth it? While it’s slightly more expensive than traditional decking materials, it’s still one of the best decking options. It’s durable, weather-proof, and needs little upkeep. You can paint a composite deck, but you also don’t have to. It can last for decades without fading into grey, as most wood decks do. Composite decks also use hidden fasteners for a beautiful, smooth, and wood-like finish. Composite decks are definitely worth it.
