(OTCQB: XERI), a company dedicated to the discovery, development, and commercialization of transformative technologies, today highlighted the potential of its NexBoard composite panel to serve as a true universal construction board. Independent laboratory testing demonstrates that NexBoard outperforms conventional drywall, magnesium oxide (MgO) board, oriented strand board (OSB), medium-density fiberboard (MDF), and plywood across critical performance categories, positioning it as a single material solution for multiple applications that traditionally require several different products. The implications of a high-performance universal panel are significant for the construction industry. Job sites could utilize the same board for interior walls, semi-structural applications, subflooring, roofing underlayment, exterior sheathing, and other uses. This consolidation has the potential to simplify logistics, reduce inventory complexity, lower waste, and create greater consistency in performance and installation methods across a project. According to independent testing summarized in Xeriant’s latest performance comparison, NexBoard delivers a combination of attributes not matched by any single traditional panel, including fire performance, impact strength, mechanical strength, water and moisture resistance, mold resistance, fastener pull-through resistance and compressive strength, in addition to its sustainability profile. “NexBoard was initially designed for interior applications, however, based on industry feedback and the third-party analysis, it appears that we may be positioned to eliminate the need for multiple specialized panels on a single job site,” said Keith Duffy, CEO of Xeriant. “When one material can deliver Class A fire performance, exceptional impact and compressive strength, zero mold growth, and the ability to withstand outdoor exposure without water damage, the traditional boundaries between interior drywall, sheathing, subflooring, and other applications begin to disappear. That is the definition of a universal board — and the practical benefits for builders in terms of simplicity, durability, and long-term performance are substantial.” Because NexBoard resists water absorption and mold even under prolonged exposure, it is suitable for both interior and exterior applications, including environments where conventional materials would degrade. Potential uses include interior wall and ceiling systems, high-traffic commercial interiors, semi-structural panels, subflooring, roofing underlayment, exterior sheathing, and other assemblies where fire, impact, moisture, or biological resistance are priorities. The ability to leave panels exposed to weather during construction without damage further supports scheduling flexibility on active job sites. NexBoard and its companion finishing compound NexPatch™, which has similar properties, are marketed under Xeriant’s DUREVER™ advanced materials brand. The Company continues to advance commercialization and supply samples to homebuilders and commercial contractors who are evaluating the panel for multi-application use. About Xeriant, Inc. Xeriant, Inc. is dedicated to the discovery, development, and commercialization of transformative technologies, with a focus on advanced materials that can be successfully integrated and deployed across multiple industrial sectors. The Company’s advanced materials line is marketed under the DUREVER™ brand and includes NexBoard™, an eco-friendly composite construction panel made from recycled plastic and fiber waste, and NexPatch™, its companion fire-resistant joint compound.
