What is Composite Decking?
Before diving into the comparison between thin and thick composite decking, it’s important to first understand what composite decking is and why it’s such a popular choice for outdoor spaces.
Composite decking is a type of decking material made from a mixture of wood fibers and plastic (usually polyethylene or PVC). This combination results in a durable and low-maintenance material that mimics the look of traditional wood without the associated problems, such as warping, splintering, and rotting.
Some of the main benefits of composite decking include:
Durability: Resistant to moisture, insects, and UV rays, making it last longer than traditional wood.
Low Maintenance: No need for sanding, staining, or sealing as with wood decks.
Eco-Friendly: Many composite decking products are made from recycled materials.
Variety of Styles: Available in a wide range of colors, textures, and finishes, allowing for great customization.
Composite decking comes in different profiles and thicknesses, with thin and thick being two of the most common options available. Let’s take a closer look at what sets them apart.
The Basics of Thin Composite Decking
Thin composite decking typically refers to decking boards that are less than 1 inch thick. These boards are generally lighter and more flexible compared to their thicker counterparts, making them easier to handle and install. The thinner construction often results in a more budget-friendly option, but it also comes with some considerations that might affect performance and longevity.
Materials and Construction of Thin Composite Decking
Thin composite decking is made from the same basic materials as thicker boards: wood fibers and plastic. The difference lies in the ratio of materials used and the board’s profile. Thinner boards often have a hollow or ribbed core structure to reduce weight while maintaining some level of strength. Some options are solid, but the general trend is to make them lighter and more flexible.
