DuxxBak® Composite Decking

Manufactured with a proprietary combination of Biodac®, rice hulls, high-density polyethylene, and other quality components, DuxxBak® composite decking stands out against the rest of the competition in life-long durability, superior color retention, and virtual inability to absorb water.

Arguably the best composite decking brand on the market today, these high-quality decking materials are both time and weather tested, providing the industry’s most long-lasting, weather-defying deck boards.

DuxxBak composite decking is available in several deck board options, each offering a beautiful, natural looking finish to enhance your outdoor living space.

DuxxBak® Dekk is a water-shedding, no-drip through, solid surface deck system. These durable deck boards feature a unique interlocking design that channels water off your deck and away from your home, creating a dry and usable outdoor living space below. DuxxBak Dekk accomplishes this in one step, eliminating the need for a secondary drainage system.

OPTIMA® Dekk is a traditional profile decking board that combines DuxxBak’s weather defying compound with state-of-the-art capping technology, bringing science and beauty together. Available in both a grooved and solid-edge profile, this composite deck board is dimensionally consistent with typical 5/4 wood decking.

OPTIMA® Dekk LT is a lightweight, reduced profile version of OPTIMA Dekk, offering all the weather defying benefits and a beautiful ArmorCap wood-grain finish but at a lower cost.

I.Dekk® tongue and groove composite decking provides a continuous surface that functions like a traditional porch floor. This highly rigid I-Beam deck board offers industry leading strength. A perfect combination of function, style, and economy.

I.Dekk® HD is the heavy-duty version of I.Dekk, integrating a robust, hollow profile (less weight per foot) with increased stiffness to meet the demands of marine and dock applications.

DuxxBak composite decking boards are scientifically formulated to last a lifetime no matter what nature throws its way. More durable than WPC and PVC, your deck will retain its beauty and structural integrity long after the competition has faded, cracked, or warped. Ideal for both residential and commercial applications.
