The achievement of a Class A fire rating for NexBoard by Xeriant is expected to positively impact Xeriant's stock price and market valuation as it validates the product's quality and opens up commercialization opportunities. This certification could also influence the broader construction materials market by introducing a new, highly-rated fire-resistant option.
Xeriant announced that its NexBoard fire-resistant construction panel has achieved a Class A fire rating based on the ASTM E84 certification testing, the highest classification available under the standard. This accomplishment is considered a major validation of Xeriant's technology and is expected to unlock commercialization opportunities and purchase orders for NexBoard. The ASTM E84 test, also known as the Steiner Tunnel Test, is a stringent industry standard for evaluating the surface burning characteristics of building materials, measuring flame spread and smoke development. NexBoard is designed as an alternative to traditional construction panels, offering resistance to water, mold, insects, and environmental degradation in addition to its fire-resistant properties. Blaine Holt and Keith Duffy of Xeriant emphasized the significance of this milestone for homebuilders and other industries.
