Xeriant's NexBoard Achieves Top ASTM E84 Class A Fire Rating, Paving Way for Commercialization

Xeriant, Inc. (OTCQB: XERI) announced that its NexBoard fire-resistant construction panel has achieved a Class A fire rating in ASTM E84 certification testing, the highest classification available under the widely recognized industry standard for evaluating flame spread and smoke development in building materials. The company said the certification validates years of product development and represents a key milestone in advancing NexBoard as an alternative to traditional drywall and other construction panels.

Management said the certification is expected to support commercialization efforts and help convert a backlog of potential customers that have been awaiting third-party validation before moving toward purchase orders. In addition to fire resistance, NexBoard is designed to provide protection against water, mold, insects and environmental degradation, targeting applications in conventional, modular and prefabricated construction.

The achievement comes as the construction industry increasingly seeks materials that enhance safety and durability. The Class A rating, which indicates the lowest flame spread and smoke development, is a critical requirement for many commercial and residential building codes. For Xeriant, this third-party validation could be a catalyst in securing orders from builders and developers who have been monitoring the product's development.

Xeriant's advanced materials line is marketed under the DUREVER brand and includes NexBoard, an eco-friendly, patent-pending composite construction panel made from plastic and fiber waste. The panel is designed to replace products such as drywall, plywood, OSB, MDF, MgO board and other materials used in construction. The company is dedicated to the discovery, development and commercialization of transformative technologies, including advanced materials, which can be successfully integrated and deployed across multiple industrial sectors.
