In today’s competitive composite decking market, our scientifically-advanced DuxxBak Composite Decking compound stands above the rest in its endurance, color retention, and virtual inability to absorb water.

Three Primary Ingredients Manufactured to Create a Mineral-Based, Better Composite Decking Impervious to Moisture, Sunlight and Temperature Extremes.

Let’s talk about each of them:

  • Rice Hulls are the outer shells of rice kernels. These hulls, which would otherwise end up in a landfill, are practically indestructible and non-absorbent, and contain naturally occurring silica, which is an enemy of mold and mildew.
  • Our second ingredient, which really sets our compound apart, is our own patented element called BioDac®. Biodac is a reclaimed mineral from the paper industry, which would also typically end up in a landfill. We developed a process, in the late 90s, to reclaim this valuable resource and use it to fortify our compound. Through a chemical process, Biodac bonds with our other compound ingredients to create deck boards that boast a rigidity previously unheard of in the industry.
  • Next up is our plastic component, which consists of all-virgin High-Density Polyethylene, or HDPE, which is the same “dairy-grade” plastic that milk jugs are made from. The all-virgin aspect of this plastic is critically important in quality control. Because where other manufacturers are using recycled plastics that make it virtually impossible to have a consistent product because of inconsistencies in their material makeup, DuxxBak products are dialed in to ensure every board is beautifully and structurally consistent in every measure.

Add to all that our colorants–which provide superior color retention–and some manufacturing lubricants, and DuxxBak composite decking boards stand ready to withstand the tests of time and the elements. No matter if it’s wet, hot, dry, or salty, our family of products are scientifically formulated to last a lifetime.

While other manufacturers are using sawdust and PVC in their composite decking compounds, we recognize the environmental instability of these compound ingredients, and prefer to manufacture a product that will last a lifetime—Your Lifetime.





Finding a Vendor that you can consider a true Partner is rare, but DuxxBak Composite Decking is that Vendor!  Our relationship with DuxxBak is nothing if not special.  Jerry and his team are friendly, professional and the most helpful people that I deal with.  Their products are high quality, competitively priced and they always ship on time!  During this time of inventory outages and long lead times, DuxxBak has always had product ready to ship and this has increased our market share from our competitors.

Their innovative line of products sells themselves and DuxxBak has remedied the issues with composite decking on many fronts! I hold DuxxBak in high esteem as a vendor, but the most important thing is our relationship as friends.

Just wanted to put in a word on the benefits of the Duxxbak decking. It’s unique design gives us the capability to offer our customers a dry space under their deck and is much more cost-effective than purchasing and installing a separate under deck system. Additionally,  it is easy to install, colorfast, attractive and gives a solid floor with no visible fasteners. Couple that with one of the best warranties in the business and you have a product that practically sells itself.
