Over 30 years of composite decking. Zero structural field failures – ever. MoistureShield’s proprietary Solid Core™ technology fully encapsulates every wood fiber in plastic, creating the only composite boards on the market warranted for installation on the ground, in the ground, or submerged in water. We carry the complete lineup at both our Illinois locations.

Reach the next level in outdoor living with a composite deck that stands up to the elements for years to come. Excel. Defy. Inspire.

Composite Decking, Railing & Lighting Built on Solid Core™

Five composite decking collections from entry-level to premium, a coordinated railing system, and integrated LED lighting – every board protected by the Solid Core Difference™.

Composite Decking Boards

Five collections built around the same Solid Core™ foundation – Vision, Meridian, Stratos, Vantage, and Elevate. Vision is the DiamondDefense™ scratch coating, CoolDeck® technology that cuts heat absorption by up to 35%, and a 50-year structural and fade warranty. Meridian delivers authentic wood grain with CoolDeck® at a mid-range price, backed by a 50-year structural and 40-year fade warranty. Stratos combines composite and PVC technology for the lightest, most durable board in the lineup. Vantage is the only uncapped composite that works like real wood.

Deck Railing Systems

MoistureShield railing kits include top rails, infill options, and hidden brackets – all code-approved and backed by a transferable lifetime limited warranty. The Traverse™ composite deck railing line, expanded in 2025 with new color options, pairs directly with MoistureShield decking collections for a cohesive finish. Each kit comes with everything needed for a clean install, including post sleeves and gate kit compatibility. ADA handrail components available for commercial applications.

Outdoor Deck Lighting

A full LED plug-and-play system with solar post caps, under-rail strips, dome lights, flush deck lights, and side and stair lights – all compatible with MoistureShield composite and Compass aluminum railing. Under-rail LED strips use an adhesive backing that connects to a 50W Bluetooth-compatible transformer without cutting or splicing wire. No electrician required. Controls dim and schedule lighting directly from a phone for year-round use across all four seasons.

30 Years. Zero Structural Field Failures.

Every composite decking brand claims durability. MoistureShield can prove it. Their Solid Core™ technology fully encapsulates individual wood fibers in plastic before the board is assembled – not just capping the surface after. The result is an impermeable barrier that water, insects, mold, and rot cannot breach, even at cut ends and fastener holes.

That distinction is what makes MoistureShield the only composite decking on the market warranted for installation in the ground, or fully submerged in water. Every other composite brand voids coverage the moment boards contact soil or standing water. MoistureShield covers it – docks, pool surrounds, below-grade patios, waterfront builds – without exception.

The track record behind that confidence is real: over 30 years in production with zero structural field failures on record. That’s not a marketing claim – it’s the reason contractors keep coming back. On the premium Vision line, DiamondDefense™ coating adds the toughest scratch and stain surface in MoistureShield’s range, and CoolDeck® technology reduces surface heat by up to 35% compared to standard capped composites in a similar color.

The Solid Core Difference™ – From the Inside Out

MoistureShield protects boards at the material level, not just at the surface. Here is what that means in practice across every product line.

Solid Core™ Technology

Individual wood fibers are fully encapsulated in plastic during manufacturing – before boards are formed and capped. Water, insects, mold, and rot have no pathway in. The core maintains its integrity even after cutting and ripping on site, which is why MoistureShield can extend warranty coverage to below-grade and submerged installations.

CoolDeck® Technology

Available on Vision and Meridian collections, CoolDeck® uses an advanced cap formulation that reflects solar heat rather than absorbing it. Surface temperatures run up to 35% cooler than standard capped composites in a matching color – a meaningful difference on sun-exposed pool decks and south-facing builds where barefoot comfort matters.

DiamondDefense™ Coating

Exclusive to Vision – MoistureShield’s premium line – DiamondDefense™ is the toughest composite cap coating in their lineup. It resists scratches, stains, and impact damage while delivering a slip resistance rating of 0.83 dry and 0.77 wet – among the highest in the composite decking category. Backed by a 50-year fade and stain warranty.

Next Core Advantage™

Stratos combines composite and PVC technology through MoistureShield’s Next Core Advantage™ process – lighter than standard composite boards, with TruTexture™ surface delivering the most realistic wood look in their range. Stronger long-term performance than standard PVC with the moisture protection MoistureShield is known for.

Frequently Asked Questions (FAQs)

Have questions about MoistureShield products and materials?

What makes MoistureShield different from other composite decking brands?

MoistureShield uses Solid Core™ technology – individual wood fibers are fully encapsulated in plastic during manufacturing, not just capped on the outside. That creates an impermeable barrier that holds even at cut ends and fastener holes. The result is the only composite decking on the market warranted for installation on the ground, in the ground, or submerged in water. No other composite brand covers that. The proof is in the production record: over 30 years with zero structural field failures.

Can MoistureShield decking really be installed underwater or in the ground?

Yes – and it’s warranted for it. Solid Core™ encapsulates every wood fiber in plastic before the board is assembled, so water has no organic material to penetrate and degrade. MoistureShield is a legitimate choice for dock decking, floating platforms, pool surrounds, below-grade patio flooring, and any application where moisture contact is constant. Traditional capped composites void warranty coverage the moment boards contact soil or standing water.

What is the difference between MoistureShield Vision, Meridian, Vantage, Stratos, and Elevate?

Vision is the premium line: DiamondDefense™ scratch coating, CoolDeck® heat reduction, highest slip resistance (0.83 dry / 0.77 wet), 50-year structural and 50-year fade and stain warranty. Meridian is mid-range capped composite with CoolDeck® available, 50-year structural and 40-year fade warranty. Stratos blends composite and PVC for a lighter, TruTexture™ surface board. Vantage is the uncapped line = reversible, bendable, and rippable like real wood = with a 50-year structural warranty. Elevate is MoistureShield’s budget entry point with full Solid Core™ protection.

What is CoolDeck® technology and which MoistureShield collections include it?

CoolDeck® is MoistureShield’s heat-reflective cap technology – the first of its kind in composite decking. It reduces surface heat absorption by up to 35% compared to standard capped composites in a similar color. It’s available on Vision (Cathedral Stone, Mochaccino, Cold Brew) and Meridian (Catalina, Citadel, Shoreside) collections. If you’re building a pool deck or a south-facing outdoor space with heavy sun exposure, CoolDeck® is worth the consideration.

What warranty does MoistureShield offer on decking?

Vision and Meridian carry a 50-year transferable structural warranty – Vision adds a 50-year fade and stain warranty, Meridian covers 40 years on fade and stain. Vantage and Elevate carry a 50-year transferable structural warranty. Stratos carries a 20-year structural warranty. All warranties are transferable to new homeowners, which adds real value when selling a property with an installed MoistureShield deck.

Does MoistureShield offer railing and lighting that match their decking?

Yes. MoistureShield’s Solid Core Composite Railing and Traverse™ composite rail line are designed to coordinate with their decking collections. Railing kits include top rails, infill options, and hidden brackets – code-approved and backed by a transferable lifetime limited warranty. Their LED lighting system is plug-and-play, compatible with both composite and aluminum railing, and connects to a Bluetooth-compatible transformer with no wire cutting or splicing required.
