What Is Composite Decking and Why Is It Important to Refresh It?
Composite decking is a man-made material composed of a blend of wood fibers and plastic, designed for outdoor flooring applications. This type of decking offers durability and low maintenance while mimicking the appearance of natural wood.
The definition of composite decking aligns with information provided by the U.S. Forest Service, which describes it as a product made from recycled materials, including wood and plastic, intended for long-term use in outdoor environments.
Composite decking combines the natural aesthetics of wood with the resilience of synthetic materials. It resists mold, warping, and fading, providing a long-lasting option for homeowners. This decking is also recyclable, promoting environmental sustainability.
According to the American Wood Council, composite decking materials typically contain around 50% recycled materials, which helps reduce waste and promote eco-friendly building practices.
Several factors can lead to the need to refresh composite decking. UV exposure, moisture, and general wear over time can cause fading, discoloration, and surface degradation. These conditions can diminish the surface’s protective qualities.
Data from the Composite Materials Handbook indicates that proper maintenance can extend the lifespan of composite decking by up to 25%. Regular cleaning and restoration can prevent more significant damage, supporting long-term durability.
Refreshing composite decking is vital as it preserves the aesthetic appeal of outdoor spaces, increases the lifespan of the material, and enhances safety by preventing slip hazards.
The impacts of neglecting composite decking include increased maintenance costs, reduced property value, and potential safety risks due to surface wear, which could lead to accidents.
