When a professional deck builder chooses the materials they stake their reputation on, they don't make that decision lightly. They're thinking about performance ten and twenty years out. They're thinking about whether the system they recommend will still look and function the way it did on day one or whether they'll be fielding callbacks and frustrated homeowner calls a few seasons later.

That's exactly the standard we hold ourselves to at DuxxBak.

We manufacture composite decking in Green Bay, Wisconsin, and we have for decades. What we've built isn't just a product line, it's a system engineered from the ground up to solve the problems that traditional decking materials, and even most composite competitors, consistently fail to address.

Here's what separates us. And why the builders who know us best don't go back.

The Problem with Most Decking (Including Composites)

Before we talk about what DuxxBak is, it's worth being honest about what most decking isn't.

Wood rots. It warps, cracks, splinters, and requires constant maintenance — staining, sealing, sanding — just to hold its own against normal weather. Most homeowners who've owned a wood deck know this cycle well. In fact, experts note that deck joist rot and water damage are among the leading causes of premature deck failure — not because homeowners neglect the surface, but because water finds its way through and settles into the structure beneath.

Composite decking was supposed to solve that. And in some ways it did. But most composite products still have a fundamental flaw: they let water through. As industry experts have documented, even composite boards using wood fiber in their core can become susceptible to mold and structural degradation when moisture isn't properly managed. This is problem that compounds over time when the under-deck space has no drainage solution.

Water that passes through a deck doesn't disappear. It collects on joists, on framing, on the foundation below. Over time, it accelerates the decay of the very structure holding the deck up. It creates the damp, unusable dead space underneath a deck that homeowners simply have to ignore. And for multi-story homes, apartments, or stacked balconies, it becomes a real liability problem.

Most composite decking addressed the surface. DuxxBak addressed the system.

How DuxxBak Actually Works: A Water-Shedding System, Not Just a Deck Board

DuxxBak Dekk is the only complete, non-vinyl composite water-shedding deck system on the market. That distinction matters more than it might sound.

Our flagship DuxxBak Dekk board is engineered with a watertight profile that actively channels water off the surface and away from the deck structure. No secondary drainage system required. Rain, snow melt, spills...none of it passes through to the space below. Instead, it's directed out over the deck's edge, keeping the framing dry, the foundation protected, and the area underneath fully functional.

That "underneath" part is significant. Homeowners with a DuxxBak deck get usable outdoor living space below the deck — dry storage, a covered patio area, a sheltered outdoor room. Not wasted, damp square footage. Functional space that adds real value to a home.

For multi-family housing, apartment balconies, and commercial applications, this isn't just a nice feature. It's a requirement. DuxxBak Dekk eliminates the concern about what happens on the floor above — all liquids and debris are diverted away, period.

Contractors and builders who want a deeper look at what makes this system work can visit our residential applications page and commercial applications page for real-world use cases across both markets.

The Material Science Behind the Performance

DuxxBak products are engineered at a molecular level to perform where other decking products fail. You can explore the full breakdown on our material science page, but here's the core of what goes into every board we make:

HDPE (High-Density Polyethylene) — A durable, moisture-resistant structural base that gives our boards their foundational strength and prevents water absorption at the core.

Rice Hulls — A smarter, more stable alternative to wood fiber. Unlike wood-based fillers used in traditional composite boards, rice hulls don't swell, crack, or degrade when exposed to moisture cycles.

BioDac® — Our patented mineral stiffener. This is the component that gives DuxxBak boards their exceptional rigidity, fade resistance, and long-term dimensional stability. It's what separates our compound from anything else on the market.

Color-Locking and Stabilizing Additives — Including antifungal agents that prevent mold and mildew growth, UV stabilizers that fight color fade, and heat-retention inhibitors that keep the surface comfortable underfoot even in direct sun.

Everything is blended in-house at our Green Bay facility, which means the consistency and quality of every board that leaves our plant isn't left to a third-party supplier's standards.

The result: boards that don't swell, crumble, crack, or warp due to weather exposure. No painting, staining or waterproofing. Ever.

One Standard Across Every Product Line

This is something we're deliberately proud of, and something we think the industry gets wrong constantly.

Many decking manufacturers offer tiered product lines consisting of entry-level, mid-range, and premium. In practice, that tiering means buyers who don't choose the top tier are accepting trade-offs in durability, material quality, or warranty protection.

We don't believe homeowners or contractors should have to make that trade-off.

Every DuxxBak product line from our flagship DuxxBak Dekk to our Optima Dekk, I.Dekk, and Commercial Dekk lines — is engineered to the same performance standard and backed by the same warranty. Choosing a different board profile or color palette doesn't mean compromising on what the board is made of or how long it will last.

Our product family includes:

• DuxxBak Dekk — The original water-shedding, No Drip Through Decking™. Available with our ArmorCap finish (embossed wood-grain) or Traction finish (wire brushed).
• I.Dekk® — A high-strength, tongue-and-groove, skid-resistant, I-Beam deck board. Also available in S4S profile.
• I.Dekk® HD — A heavy-duty version rated for spans up to 28 inches. Ideal for marine and commercial applications.
• Commercial Dekk™ — Engineered for high-traffic commercial environments.
• Optima Dekk® — Our stunning ArmorCap traditional deck board in five variegated colors.
• Optima Dekk LT® — A lightweight version of Optima Dekk® in three solid colors.

Different applications. Same uncompromising standard.

Made in Green Bay, Wisconsin — On Purpose

Every component of the DuxxBak system is sourced and manufactured in the United States. Our headquarters, our production facility and our R&D lab are located in Green Bay.

This isn't a marketing claim. It's a deliberate business choice that we've maintained because we believe it produces a better product and because we believe it matters.

Manufacturing domestically allows us to maintain direct oversight of every stage of production — from raw material sourcing to quality control to final inspection. There's no overseas supply chain uncertainty, no quality gaps introduced by international shipping or third-party manufacturing standards.

It also means we're investing in American workers and American communities. As a Green Bay company, we're part of the fabric of this region. The people who make DuxxBak decking live in the same communities where our products are installed. The connection to the work and to the homeowners who ultimately use it, is something we don't take for granted.

When contractors and builders choose DuxxBak, they're not just selecting a product that will perform for their clients. They're supporting a domestic manufacturing ecosystem that other trades and industries depend on.

Why Builders Choose DuxxBak

We've had the privilege of hosting contractors at our Green Bay facility over the years who install our products and want to understand the process behind what they're recommending to homeowners. One example is Heritage Deck & Frame, a certified DuxxBak installer serving the Pittsburgh area. Their team made the trip to Green Bay specifically to see how and why our system is built the way it is. Their experience speaks to something we hear often: seeing the facility changes how builders think about the product.

Walking through a manufacturing operation and watching materials move from raw inputs through formulation, extrusion, quality testing, and final inspection — gives a builder a completely different relationship with the boards they're installing. They understand why the system performs the way it does. They understand what they're standing behind.

That transparency is intentional on our part. We have nothing to hide in how we make our products, and everything to gain by letting the builders who trust us see exactly what goes into them.

We also invest heavily in contractor education and certification. Our certified contractor program isn't just a sales channel, it's a community of builders who understand the DuxxBak system at a technical level, can install it correctly, and can communicate its advantages to homeowners with confidence. Certified contractors receive exclusive job leads, priority marketing support, labor warranties, and ongoing access to training and product resources.

Homeowner Piece-of-Mind

For a homeowner, finding a DuxxBak certified contractor means finding someone who has done the work to understand what they're building with.

The decking industry as a whole is supported by organizations like NADRA (North American Deck and Railing Association) who sets professional standards for builders, inspectors, and manufacturers alike. DuxxBak is proud to be a NADRA member, and we encourage homeowners to use NADRA's resources when evaluating any deck professional or product.

The Maintenance Reality: What "Low Maintenance" Actually Means

The decking industry has trained consumers to accept "low maintenance" as a relative term. Lower than wood? Sure, most composites qualify. But what does it actually mean to own the deck for twenty years?

With DuxxBak, it means cleaning it. Our care and cleaning guide covers everything a homeowner needs to keep their deck looking and performing its best — and it's a short read, because the list is short.

No sealants to reapply, no stains to refresh, no boards to replace because water infiltrated the core and caused rot from the inside out. Safe ice-removal products like sodium chloride and calcium chloride can be used without damaging the surface. The boards won't crack in freeze-thaw cycles, won't swell in humidity, and won't fade prematurely under UV exposure.

That's what genuine low maintenance looks like and it's the promise every DuxxBak board is engineered to keep.

For Contractors: What Choosing DuxxBak Means for Your Business

We understand that a contractor's product choice is also a business decision. Here's what working with DuxxBak looks like in practice:

Fewer callbacks. Boards that perform as warranted mean fewer post-installation issues to manage.

Easier installation. Our system is designed for efficient installation, with clear technical documentation, installation guides, and a team available for product support.

A product you can sell with confidence. Homeowners who ask hard questions about durability, water management, and long-term maintenance get clear, honest answers that make the sale easier...not harder.

Consistent quality. Because our compound is blended in-house and every board goes through our QC process, you're not dealing with batch-to-batch variation.

The Bottom Line

Decking is a long-term investment for homeowners and a long-term reputation bet for the builders who install it. Both deserve a product that's engineered to actually deliver on its promises.

DuxxBak was built on that belief. Every board, every product line, every batch that leaves our Green Bay facility reflects it.

If you're a homeowner researching composite decking options, we'd invite you to order a sample and experience the material firsthand. If you're a contractor who wants to understand what's behind the product and what it could mean for your business, we'd love to talk.

Because a deck that performs for 20+ years doesn't happen by accident. And neither does the relationship between a manufacturer and the builders who trust them.
