Considering Fiberon Decking for a Coastal Home

Understanding Fiberon's Composition and Coastal Suitability

Fiberon composite decking is made from a blend of recycled wood fibers and plastics, encased in a durable cap. This capping layer is a critical feature for coastal applications, as it provides a barrier against moisture, UV radiation, and general weathering. The material's resistance to rot, decay, and insect infestation is inherently beneficial in humid, coastal settings where these issues can accelerate the deterioration of traditional wood.

The various Fiberon lines, such as Concordia, Sanctuary, and Good Life, all feature this protective capping, though with differences in their specific composition and coverage (e.g., three-sided vs. four-sided). This capping helps maintain the board's aesthetic and structural integrity against the daily challenges of a coastal climate, including salt spray and intense sunlight.

The primary advantage in a coastal setting is the significantly reduced maintenance compared to wood, freeing homeowners from frequent staining or sealing tasks to combat salt and moisture.

Impact of Salt Exposure on Composite Decking

Coastal homes are constantly exposed to salt-laden air and occasional salt spray, which can be corrosive to many building materials. Fiberon's capped composite structure is formulated to resist the corrosive effects of salt, preventing it from penetrating the core of the board. The polymer cap acts as a shield, making the surface resistant to salt-induced discoloration or degradation that might affect uncapped composites or natural wood.

Regular cleaning with soap and water is generally recommended for Fiberon decking. In coastal areas, this simple maintenance routine becomes even more important to rinse away accumulated salt deposits and prevent potential buildup, which could lead to surface residue over time. This proactive cleaning helps preserve the deck's appearance and performance.

Selecting Compatible Fasteners and Hardware

In coastal environments, the choice of fasteners and hardware is as crucial as the decking material itself. Standard galvanized screws or clips may corrode quickly when exposed to salt air, leading to structural compromise and unsightly rust stains on the deck surface. For Fiberon decking, which supports both hidden clip and face screw fastening methods, selecting corrosion-resistant options is essential.

When using hidden fastening systems, ensure the clips and any associated components are also made from appropriate corrosion-resistant materials. For face-fastening, screws explicitly rated for outdoor, coastal use should be chosen. Always confirm compatibility with Fiberon's installation guidelines and the specific product line.

Similarly, any other hardware used in conjunction with the deck, such as ledger board connectors, joist hangers, or railing components, should be specified for coastal or marine environments to ensure long-term integrity and prevent premature failure.

Warranty Considerations for Coastal Properties

These warranties typically cover manufacturing defects that lead to staining or fading under normal use. When planning a deck for a coastal home, it's important to review the specific warranty terms carefully.

While Fiberon products are designed for durability in various climates, understanding any exclusions or conditions related to extreme environmental factors, such as prolonged saltwater submersion or specific maintenance requirements, is prudent. Generally, the standard cleaning and maintenance protocols outlined by Fiberon are sufficient to maintain warranty validity, even in coastal settings. Always retain proof of purchase and installation details, and adhere to manufacturer recommendations for cleaning and care.

Worked Example: Decking a Coastal Veranda

Consider a coastal home planning a 12-foot by 20-foot veranda deck. The homeowner prioritizes low maintenance and a natural wood aesthetic without the upkeep.

For this 240 square foot deck (12 ft x 20 ft), using 20-foot Fiberon Sanctuary boards (1 inch x 5.5 inch profile) minimizes seams. For a 20-foot length, this means 26 boards each 20 feet long. Total lineal footage: 26 boards * 20 feet/board = 520 lineal feet. The project will require approximately 520 lineal feet of Fiberon Sanctuary decking. For edge finishing, matching Fiberon fascia boards are chosen, also in 'Chestnut'.

All underlying structural hardware, such as joist hangers and ledger board fasteners, will also be stainless steel to resist salt corrosion. The homeowner understands the need for annual soap-and-water cleaning to remove salt residue and keep the deck looking its best.

This approach ensures both the decking material and the fastening system are appropriate for the demanding coastal environment, contributing to the longevity and reduced maintenance of the veranda.

Before you order

• Confirm Fiberon product line (Concordia, Sanctuary, Good Life) and its specific capping details (3-sided vs. 4-sided).
• Verify the chosen Fiberon product's warranty terms for coastal applications.
• Plan for regular cleaning to remove salt residue (annual soap-and-water wash).
• Consider matching Fiberon fascia and riser boards for a cohesive, low-maintenance finish.
• Ensure proper deck ventilation to prevent moisture buildup beneath the deck surface.
• Review local building codes for any specific requirements related to coastal construction materials and fasteners.

Confirm installation details, approved uses and warranty terms in the current instructions for the exact product and profile. Your installer should verify the substrate, structure and applicable project requirements.
