Welcome to our dedicated page for Xeriant news (Ticker: XERI), a resource for investors and traders seeking the latest updates and insights on Xeriant stock.
Xeriant, Inc. reports developments tied to advanced materials, fire-resistant composite technology, and commercialization activity. Company updates center on the DUREVER™ advanced materials platform, NEXBOARD™ composite construction panels, and NexPatch™, a fire-resistant joint compound designed for NEXBOARD installations.
Recurring news themes include internal and third-party fire-performance testing, patent and trademark activity, manufacturer interest in fire-retardant formulations, and the Factor X Research Group’s role in identifying and developing technologies across construction, aerospace, security, and related industrial markets.
Xeriant (OTCQB: XERI) reported independent laboratory results indicating that its NexBoard™ composite panel outperforms conventional drywall, MgO board, OSB, MDF, and plywood across multiple performance categories. According to Xeriant, testing showed advantages in fire performance, impact and mechanical strength, water and moisture resistance, mold resistance, fastener pull-through resistance, and compressive strength.
The company highlights NexBoard as a potential universal construction board suitable for interior walls and ceilings, semi-structural uses, subflooring, roofing underlayment, exterior sheathing, and high-traffic commercial interiors. NexBoard and its companion finishing compound NexPatch™ are marketed under Xeriant’s DUREVER™ advanced materials brand, with samples currently supplied to builders and contractors for evaluation.
Xeriant (OTCQB: XERI) reported that its NEXBOARD composite construction panel achieved a perfect score of 10 on the independent ASTM D3273 mold resistance test, with zero mold growth after 28 days. Standard drywall typically scores 6–8, while OSB and MDF commonly score 3–5.
NEXBOARD also recorded very low water absorption of 3.47% after 24 hours under ASTM D570, versus 25–35% for conventional drywall, and complements a previously reported Class A fire rating (ASTM E84) and successful NFPA 286 room burn test. Xeriant said materials for a large-scale NEXBOARD sample production run will arrive at its contract manufacturer this week as it advances commercialization and supplies samples to builders.
Xeriant (OTCQB:XERI) is promoting NEXBOARD™, a composite construction panel designed to compete on measurable performance rather than environmental claims alone. According to Xeriant, NEXBOARD has achieved Class A performance under ASTM E84 and passed the NFPA 286 full-room corner burn test, two key fire-safety standards.
The company states that NEXBOARD is hydrophobic and highly mold-resistant, helping buildings withstand fire, water and mold damage simultaneously. NEXBOARD is manufactured with recycled materials, aiming to combine sustainability and durability. Xeriant highlights that commercial success will depend on scaling manufacturing, competitive pricing, distribution, contractor acceptance and meeting regulatory requirements.
Xeriant (OTCQB: XERI) announced that the U.S. Patent and Trademark Office has issued U.S. Patent No. 12,679,047 for its proprietary multilayered fire-resistant polymer composite and related manufacturing method. The patent covers the core technology used in NEXBOARD, an eco-friendly construction panel made from recycled plastic and fiber waste.
According to Xeriant, this patent strengthens intellectual property protection for both NEXBOARD and the broader DUREVER advanced materials platform. The multilayered design allows high concentrations of non-toxic fire retardants in the outer layers with recycled materials in the core, targeting applications in construction and potentially aerospace, transportation, and energy. Xeriant is also pursuing international protection through a Patent Cooperation Treaty application and continuation filings.
Xeriant (OTCQB:XERI) reported new independent laboratory results showing its 3/8-inch NEXBOARD eco-composite panel significantly outperforms traditional materials such as drywall, MgO board, OSB, MDF and plywood across multiple performance metrics. NEXBOARD, using proprietary Durazite fire-retardant technology, achieved a Class A fire rating under ASTM E84 and passed the NFPA 286 full-room corner burn test, a key requirement for many commercial and institutional fire codes.
The tests indicated superior impact resistance, tensile strength, and low water absorption, along with low VOC emissions and competitive R-value. According to Xeriant, NEXBOARD is manufactured primarily from recycled plastic and fiber waste, is fully recyclable, avoids formaldehyde off-gassing, and is expected to contribute to LEED and GREENGUARD green building certifications for high-traffic and high-risk interior environments.
Xeriant (OTCQB:XERI) published an updated 36-page white paper titled “Disaster Susceptibility, Environmental Pollution, and Unaffordable Housing: Xeriant’s Resilient and Sustainable Solution.”
It showcases certified NexBoard and new NexPatch as fire-resistant, waste-based construction materials aimed at resilient, affordable, sustainable housing.
Xeriant (OTCQB:XERI) is initiating the next production run of its patented NEXBOARD™ composite building panels under the DUREVER™ line. This campaign will supply samples to leading homebuilders and commercial construction firms that requested material for evaluation and internal testing.
NEXBOARD recently achieved a Class A rating under ASTM E84 for flame spread and smoke development and NFPA 286 corner room burn test certification. These fire safety milestones have drawn interest from prospective customers and support Xeriant’s commercialization efforts for this eco-friendly alternative to traditional wallboard products.
Xeriant (OTCQB:XERI) reported that its NexBoard fire-resistant eco-friendly construction panel successfully passed the rigorous NFPA 286 corner room fire test, a key fire safety and commercialization milestone.
NexBoard previously achieved a Class A ASTM E84 rating and incorporates NexPatch joint compound, which also showed strong bonding and fire resistance during testing.
Xeriant (OTCQB:XERI) announced that its NexBoard fire-resistant construction panel achieved an ASTM E84 Class A fire rating, the highest classification under this industry-standard Steiner Tunnel Test. Testing showed no combustion and no smoke generation, key factors for builders and regulators.
According to Xeriant, the certification is a foundational milestone expected to help unlock a commercialization backlog awaiting third-party validation, with additional building materials tests underway as part of a broader certification program.
Xeriant (OTCQB:XERI) scheduled initial third-party certification testing this week for its NexBoard composite panel and NexPatch joint compound. An internal 30-minute timelapse video shows NexBoard exposed to sustained flame temperatures above 2,000°F with no combustion and no smoke, key fire-safety metrics for building materials.
According to Xeriant, NexBoard is also resistant to water, mold and insects and, with NexPatch, forms part of its DUREVER advanced materials platform as the company advances toward certification and broader applications.
