Understanding Coastal Exposure
Coastal environments present unique challenges for exterior materials. Key factors include consistent exposure to salt-laden air, which can accelerate corrosion of certain metals and impact material surfaces. High humidity levels and intense UV radiation also play a significant role in material degradation over time.
When considering NewTechWood composite products, it's essential to assess the specific degree of exposure your project will face. Is it directly on the beachfront, subject to direct salt spray, or is it a few blocks inland with only ambient salty air? The closer proximity to the ocean and the more direct the exposure, the more critical your material and fastening selections become.
NewTechWood Composite Materials
NewTechWood products are wood-plastic composites designed to offer a wood-look surface with reduced maintenance compared to traditional wood. These materials are suitable for exterior applications like cladding, siding, and other outdoor surfaces. Their composite nature generally provides stability against moisture absorption, which can be beneficial in humid coastal climates.
However, "low-maintenance" does not mean "no maintenance." While NewTechWood resists rot and insects, surfaces still require periodic cleaning to remove salt buildup, dirt, and other environmental contaminants. The specific profile and color chosen can also influence how noticeable such deposits are over time.
Lumber Plus helps match the application, profile, and local availability to your project. It is always recommended to request current physical samples to assess appearance and texture in your project's specific lighting and environmental conditions.
Fastening and Hardware in Coastal Settings
Standard steel fasteners, even galvanized ones, can be susceptible to accelerated corrosion from salt spray. This corrosion can lead to structural compromise and unsightly staining on the composite material.
For coastal applications, it is generally recommended to specify marine-grade stainless steel fasteners. Confirm the specific grade (e.g., 304 or 316) appropriate for your project's exposure level, as 316 stainless steel offers superior corrosion resistance in saltwater environments. Always verify compatibility with NewTechWood's recommended installation guidelines for your chosen profile.
Consider all exposed metal components, including trim, brackets, and any decorative elements. Ensure all are selected for high corrosion resistance to match the expected lifespan of the composite surface.
Profile and Design Choices for Coastal Elevations
NewTechWood offers various composite profiles suitable for exterior facades and accent walls. When designing for a coastal elevation, consider how profile choices might impact drainage and drying. Profiles that allow for efficient water runoff and air circulation can help minimize moisture accumulation and salt residue buildup.
For example, a rainscreen assembly, which creates a ventilation gap behind the cladding, can be particularly beneficial in humid coastal areas. This gap helps to dry the wall assembly, reducing the potential for moisture-related issues. Confirm the wall assembly, profile direction, trim, and fastening method with your supplier before ordering.
Colors and finishes should also be considered. Darker colors may absorb more solar radiation, potentially leading to higher surface temperatures, which can be a factor in intense coastal sun. Lighter colors may show environmental deposits more readily but can also reflect more heat.
Hypothetical Project: Coastal Decking Overlay
Imagine a 10-foot by 12-foot elevated deck on a coastal property, overlooking the ocean. The existing treated lumber deck framing is structurally sound but the surface boards are weathered. The homeowner wants a low-maintenance, wood-look surface using NewTechWood composite decking. The deck is exposed to direct salt spray during high tides and storms.
For this project, the primary considerations are: 1) direct salt spray exposure, 2) high humidity, and 3) intense UV. The design specifies NewTechWood UltraShield Naturale decking planks, which are 0.98 inches thick by 5.4 inches wide and come in 16-foot lengths.
The deck design incorporates a slight slope for drainage away from the house. A total area of 120 square feet needs to be covered. Each 16-foot plank covers approximately 7.2 square feet (16 ft * 5.4 in / 12 in/ft). To cover 120 square feet, approximately 17 planks would be needed (120 / 7.2). Allowing for cuts and waste, 19-20 planks would be a safer estimate.
Regular rinsing with fresh water will be recommended as part of the maintenance to remove salt buildup.
Before you order
- Assess the specific degree of coastal exposure (direct spray vs. ambient salt air).
- Confirm NewTechWood product suitability and manufacturer recommendations for coastal use.
- Consider wall assembly details like rainscreens for enhanced drainage and ventilation.
- Choose profiles and colors that balance aesthetic goals with practical coastal performance.
- Plan for routine cleaning to remove salt and environmental buildup.
- Request current physical samples to evaluate appearance in project conditions.
- Confirm current availability of chosen profiles and coordinating accessories with Lumber Plus.
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.
Questions to help you decide
Are NewTechWood products resistant to salt water?
NewTechWood composite products are designed for outdoor applications and exhibit good resistance to moisture. However, direct and continuous exposure to salt water or salt spray over time can still lead to salt residue buildup. While the material itself is durable, the primary concern in coastal environments often shifts to the choice of fasteners and the need for periodic cleaning to remove salt deposits. Always consult product-specific documentation for detailed resistance information.
What kind of maintenance is required for NewTechWood in a coastal area?
In coastal areas, NewTechWood surfaces will benefit from more frequent cleaning than in less exposed environments. Regular rinsing with fresh water can help remove salt spray and airborne contaminants, preventing buildup and potential staining. Follow the manufacturer's general cleaning guidelines, typically involving mild soap and water, and avoid abrasive cleaners or tools that could damage the surface. Inspect fasteners periodically for any signs of corrosion.
Can NewTechWood be installed directly on existing wooden structures near the coast?
NewTechWood composite cladding and decking can often be installed over existing, structurally sound substructures. For coastal applications, ensure the existing structure is in good condition and can support the new material. Critically, all new fasteners must be appropriate for the coastal environment (e.g., marine-grade stainless steel). If the existing structure is also wood, consider its long-term durability in the coastal climate, as NewTechWood is a surface material and does not provide structural support to the underlying framing. Always follow NewTechWood's installation instructions regarding substructure requirements and ventilation.
