Performance Testing

NexBoard™ and NexPatch™ have been evaluated by independent, accredited third-party laboratories against the fire and life-safety standards that govern interior finish materials in North American construction.

Independent laboratories

Certified Results

ASTM E84

Class A Fire Rating. ASTM E84, the Steiner Tunnel Test, measures the surface burning characteristics of a building material. Class A is the highest of the three classifications the standard defines.

NFPA 286

Passed with zero smoke and combustion. NFPA 286 is the full-scale room corner test used to evaluate how far a wall or ceiling finish contributes to fire growth under real fire conditions.

NexPatch was tested as part of a complete NexBoard wall assembly, so both results carry through to every joint, repair and patch in the fire-rated assembly.

What NexBoard Replaces

With its certified performance, multi-use profile and environmental advantages, NexBoard is a universal alternative to drywall, plywood, OSB, MgO board, cement board, MDF and other panels used in construction, with applications across the entire building envelope.

02

Durazite™ Technology

Both products are built on the Durazite intumescent fire retardant platform. At extreme high temperatures the system activates, forming a protective insulating foam barrier that absorbs, dissipates and deflects heat. Independent third-party testing has validated its effectiveness across a broad array of performance standards, from fire protection to moisture and mold resistance.
