Hey there! As a solid PVC decking supplier, I often get asked about the thickness of solid PVC decking. It's a crucial factor that can impact the performance, durability, and overall look of your deck. So, let's dive right in and explore what you need to know about the thickness of solid PVC decking.


Why Thickness Matters
First off, why does the thickness of solid PVC decking matter? Well, it plays a significant role in determining the strength and stability of your deck. A thicker decking board can generally handle more weight and stress without warping or bending. This is especially important if you plan to use your deck for activities like hosting parties or placing heavy furniture on it.
Thickness also affects the lifespan of your deck. Thicker boards are often more resistant to wear and tear, which means they'll last longer and require less maintenance over time. Additionally, a thicker decking can provide better insulation, keeping your deck cooler in the summer and warmer in the winter.
Common Thicknesses
Solid PVC decking comes in a variety of thicknesses, but the most common ones range from 0.7 inches (18mm) to 1 inch (25mm). Let's take a closer look at each of these thicknesses and their typical uses:
- 0.7 inches (18mm): This is a relatively thin option for solid PVC decking. It's lightweight and easy to install, making it a popular choice for DIY projects or decks with a simple design. However, it may not be as durable as thicker boards and may not be suitable for heavy use or high-traffic areas. If you're looking for an affordable option for a small deck or a deck that won't see a lot of activity, 0.7-inch decking could be a good choice. You can check out our Pvc Decking For Sale page to see if we have this thickness available.
- 0.8 inches (20mm): This is a mid-range thickness that offers a good balance between strength and cost. It's more durable than 0.7-inch decking and can handle moderate traffic and weight. Many homeowners choose 0.8-inch decking for their backyard decks because it provides a decent level of quality without breaking the bank.
- 1 inch (25mm): This is the thickest and most durable option for solid PVC decking. It's ideal for commercial applications or decks that will be subject to heavy use, such as decks around swimming pools or in high-traffic areas. 1-inch decking is also more resistant to scratches and dents, which means it will maintain its appearance better over time. If you're looking for a top-of-the-line decking solution, this is the way to go. You might also want to explore our Cellular PVC Decking options, which can sometimes come in this thicker size.
Choosing the Right Thickness
So, how do you choose the right thickness for your solid PVC decking? Here are some factors to consider:
- Intended Use: Think about how you'll be using your deck. If it's just for relaxing and enjoying the outdoors, a thinner decking may be sufficient. But if you plan to host large gatherings or use your deck for activities like grilling or playing games, you'll want a thicker, more durable board.
- Budget: Thicker decking generally costs more than thinner decking. So, you'll need to balance your budget with your desired level of quality and durability. Keep in mind that investing in a thicker decking upfront can save you money in the long run by reducing the need for repairs and replacements.
- Climate: If you live in an area with extreme weather conditions, such as hot summers or cold winters, a thicker decking may be more resistant to temperature changes and less likely to warp or crack.
- Deck Design: The design of your deck can also influence your choice of thickness. For example, if you're building a multi-level deck or a deck with a complex shape, you may need a thicker board to provide the necessary support.
Installation Considerations
When it comes to installing solid PVC decking, the thickness of the boards can affect the installation process. Thicker boards may be heavier and more difficult to handle, so you'll need to make sure you have the right tools and equipment. You may also need to use longer screws or nails to secure the boards properly.
It's also important to follow the manufacturer's installation instructions carefully to ensure that your deck is installed correctly and safely. If you're not comfortable installing the decking yourself, it's always a good idea to hire a professional contractor who has experience working with solid PVC decking.
Maintenance and Care
Regardless of the thickness of your solid PVC decking, proper maintenance and care are essential to keep it looking its best and lasting for years. Here are some tips to help you maintain your deck:
- Clean Regularly: Use a mild soap and water solution to clean your deck regularly. This will help remove dirt, debris, and stains. Avoid using harsh chemicals or abrasive cleaners, as they can damage the surface of the decking.
- Inspect for Damage: Periodically inspect your deck for any signs of damage, such as cracks, scratches, or loose boards. If you notice any issues, address them promptly to prevent further damage.
- Protect from the Elements: If possible, cover your deck during the winter months or when it's not in use to protect it from the elements. You can also apply a protective sealant to the decking to help prevent fading and damage from UV rays.

In conclusion, the thickness of solid PVC decking is an important factor to consider when building or renovating your deck.
