NEXBOARD™ Achieves Perfect Score of 10 in Independent Mold Resistance Testing

  • Xeriant Inc. announced its NEXBOARD composite panel achieved a perfect score of 10 on the ASTM D3273 mold resistance test with zero growth after 28 days.
  • NEXBOARD demonstrated exceptionally low water absorption of 3.47% after 24-hour immersion, compared to 25–35% for conventional drywall.

  • CEO Keith Duffy stated NEXBOARD offers built-in resistance to moisture \& mold rather than relying on coatings that can fail.
  • The panel holds a Class A fire rating under ASTM E84 \& passed the NFPA 286 full-room corner burn test.
  • All materials for a large-scale sample production run will be delivered to the contract manufacturer this week.
