Decking Supplies in Champaign, IL

Composite decking is made from a blend of wood fibers and recycled plastics, making it highly resistant to rot, insects, and fading with very low maintenance needs. Traditional wood decking, like pressure-treated pine or cedar, offers a natural look and can be less expensive upfront but requires regular sealing, staining, or painting. Wood can also be more prone to warping and splintering over time. The choice often comes down to budget, desired appearance, and how much maintenance you’re willing to do.

In Champaign’s climate, composite and PVC decking typically handle freeze-thaw cycles and seasonal humidity better than many natural woods. These materials are engineered to resist moisture absorption, which helps reduce swelling, warping, and cracking in extreme temperature swings. If you prefer wood, look for pressure-treated lumber rated for ground contact or naturally durable species like cedar, and be diligent about sealing. Proper ventilation under the deck and correct installation of fasteners also greatly improves long-term performance.

The best fasteners depend on your decking material and the look you want. Composite and PVC boards often work well with manufacturer-approved hidden clip systems that maintain consistent board spacing and create a clean, screw-free surface. For wood, stainless steel or coated deck screws are usually recommended to prevent rust and staining. Always check the decking manufacturer’s installation guidelines, as using the wrong fasteners can void warranties or lead to premature board failure.

PVC decking is made entirely from plastic, so it’s very resistant to moisture, mold, and insects, and is often lighter than composite boards. Composite decking contains wood fibers, which can give it a more natural look and feel but may be slightly more prone to surface staining or fading over time. PVC can sometimes have a higher upfront cost but may offer better color retention and easier cleaning. When comparing, look at slip resistance, heat retention, warranty length, and how each product’s color and texture match your design goals.

Lighter-colored decking materials, whether composite, PVC, or wood, generally stay cooler in direct sun than darker colors. Some premium composite and PVC lines are engineered with heat-reflective technology to reduce surface temperature, which can make a noticeable difference on hot days. Wood, especially lighter species like cedar, can also feel cooler than some dense composites. If heat is a major concern, compare sample boards in direct sunlight and consider adding shade structures or rugs in high-use areas.

Most composite and PVC decking products require joist spacing of 16 inches on center for standard residential installations, though some may need 12 inches for diagonal patterns or heavier loads. Wood decking can sometimes span slightly wider distances, but local building codes and manufacturer instructions should always be followed. In Champaign’s climate, using properly treated lumber for the substructure and ensuring good drainage and airflow under the deck are crucial to prevent rot and movement. Always confirm span and spacing requirements on the product’s technical sheet before purchasing materials.
