Xeriant Begins NexBoard Certification Testing, Demonstrates Fire Resistance in Extreme Conditions

Xeriant, Inc. (OTCQB: XERI) has announced that initial certification testing for its NexBoard™ composite construction panel and NexPatch™ joint compound is scheduled to begin this week. The company also released a 30-minute internal timelapse video demonstrating NexBoard undergoing extreme fire testing, during which the panel was exposed to sustained flame temperatures exceeding 2,000 degrees Fahrenheit without combusting or producing smoke. Xeriant said the results highlight the effectiveness of its proprietary intumescent fire-retardant technology as it moves the products toward third-party certification and broader commercial applications.

This development is significant for the construction industry, where fire safety is a critical concern. NexBoard, marketed under the DUREVER™ brand, is an eco-friendly, patent-pending composite panel made from plastic and fiber waste, designed to replace traditional materials like drywall, plywood, OSB, MDF, and MgO board. The fire-resistance performance demonstrated in the video positions NexBoard as a potential safer alternative, especially in applications where fire codes are stringent. The lack of combustion and smoke generation at such high temperatures could reduce fire spread and toxic smoke inhalation risks, which are leading causes of fire-related injuries and deaths.

For Xeriant, successful certification could open doors to wider adoption in residential and commercial construction. The company’s focus on transformative technologies, including advanced materials, aligns with growing demand for sustainable and safer building products. The certification process is a critical step toward proving NexBoard’s reliability and market readiness. Investors and industry observers will be watching closely, as certification can significantly enhance product credibility and market access.

Xeriant’s advanced materials line, which includes NexBoard and NexPatch, is part of a broader strategy to partner with and acquire strategic interests in visionary companies. The company’s commitment to integrating its technologies across multiple industrial sectors suggests that NexBoard could eventually see applications beyond construction, such as in transportation or aerospace, where fire resistance is paramount.

The video release and certification testing represent concrete progress for Xeriant. For more information on Xeriant and its latest updates, visit the company’s newsroom at https://ibn.fm/XERI. The full press release is available at https://ibn.fm/18mEV.
