Durability. Safety. Sustainability.



To foster sustainable practices in the construction industry by developing high performance composite building products derived from recovered waste materials.


Xeriant, Inc. is a company dedicated to the discovery, development and commercialization of emerging aerospace technologies, including next generation air and spacecraft, and advanced eco-friendly materials which can be successfully integrated and commercialized for deployment across multiple industry sectors. We seek to partner with and acquire strategic interests in visionary companies that accelerate our mission.
Xeriant’s advanced materials line is marketed under the DUREVER™ brand and includes NEXBOARD™, an eco-friendly, patent-pending composite building panel.
Xeriant is located at the Research Park at Florida Atlantic University in Boca Raton, Florida adjacent to the Boca Raton Airport.


DUREVER™ is a brand of high-performance, eco-friendly polymer composite building products made from recovered plastic and cellulose fiber waste and a proprietary non-toxic fire retardant. Developed by Xeriant, DUREVER™ advanced composites are a superior and green alternative to traditional building materials, providing exceptional strength and resistance, and are 100 percent recyclable.  A patent was filed relating to the composite’s novel formulation, layering architecture and production process.
The flagship of the DUREVER™ line of composite building products is NEXBOARD™, a more durable, green alternative to traditional construction panels such as drywall, OSB and plywood, with potential applications for interior walls and ceilings, exterior walls and roof sheathing, flooring and subflooring.
Xeriant plans to introduce additional eco-friendly building products such as framing boards, support beams, decking, trim, doors and window casings, marketed under the DUREVER™ brand. Xeriant’s advanced composites are also a more durable wood replacement for furniture and cabinets and potentially have applications in the aerospace, automotive and marine industries.  Xeriant may also develop and market fire-retardant products and related specialty coatings.



NEXBOARD™ is a versatile, highly durable, green composite building panel designed to replace drywall, plywood, OSB, MDF, MgO board and other products used in the construction of walls, roofing, flooring and ceilings.  Made from recovered plastic and cellulose fiber waste and a proprietary non-toxic fire retardant, NEXBOARD™ is resistant to fire, water, mold, insects and corrosion, and is insusceptible to abrasion or cracking, which is often a problem for drywall during handling, transport or installation.
NEXBOARD™ does not need priming or sealing, and accepts knockdown textures, wall coverings, tile and most paints. Panels will be available in various thicknesses and standard sizes, including 48” x 96” sheets, and weigh significantly less than comparably sized gypsum- and wood-based panels.  NEXBOARD™ represents a significant breakthrough in the construction industry’s transition to a circular economic model.
NEXBOARD™’s non-toxic fire retardant is based on a proprietary chemical formulation specifically developed for plastic composites. When exposed to fire, a thermolytic reaction forms an insulating layer, a process called intumescence, which prevents fire penetration and flame spread, absorbs heat, and releases only harmless non-toxic gases, while retaining the mechanical features of the board.  Testing and certifications are currently in the process of being completed.
