Performance Dashboard

NexBoard achieved a Class A rating under ASTM E84 (FSI 2.5 / SDI 0) and passed the full-room NFPA 286 corner fire test — the most demanding fire test for interior wall products. OSB, MDF, and plywood all fail NFPA 286 outright, making NexBoard the only wood-alternative panel in this comparison that qualifies for commercial and institutional fire code applications without additional protective assembly.

At 1.2 R-value per inch, NexBoard outperforms drywall and MGO board by approximately 2×, and is competitive with wood-based structural panels (OSB, MDF, plywood) which range from 1.0–1.41 R/inch. This thermal story is strongest when positioning NexBoard as a drywall or MGO replacement.

NexBoard withstood 345 ft·lbs of soft body impact before showing damage — 8–20× greater than drywall (15–40 ft·lbs) and 4–8× greater than MGO board. In hard body impact testing, NexBoard withstood 225 ft·lbs before damage — significantly exceeding drywall (15–40 ft·lbs), MGO board (40–100 ft·lbs), and all other panels in this comparison. These results confirm NexBoard’s suitability for high-traffic commercial, healthcare, education, hospitality, and institutional environments. Under the ASTM C1629 abuse-resistance scale — where Level 3 is the highest defined classification — NexBoard exceeds the Level 3 threshold for both soft- and hard-body impact, while competing panels range from Level 1 (drywall) to Level 3 at best (OSB and plywood).

NexBoard recorded an average Izod impact resistance of 86.74 J/m (1.62 ft·lbf/in²) under the ASTM D256 pendulum impact protocol — a polymer matrix composite standard. This result confirms NexBoard’s classification as a high-performance composite material. Competing panels are not polymer composites and cannot be formally evaluated under ASTM D256. For context, published data indicates drywall core material registers approximately 10–27 J/m under comparable loading, well below NexBoard’s 86.74 J/m average; estimated analogs for MGO board, OSB, MDF, and plywood fall between roughly 20 and 80 J/m.

At 1,839 psi, NexBoard’s tensile strength is 6–12× greater than drywall, 2.6–4.6× greater than MGO board, and 1.5–2.3× greater than plywood. This result is consistent with a fiber-reinforced composite matrix and opens semi-structural application possibilities beyond standard finish panel use cases.

Under ASTM D7332, NexBoard recorded a tested range of 425–635 lbf with an average of 517 lbf and a maximum of 637 lbf — outperforming drywall by approximately 5 to 7 times and exceeding or matching the performance of all wood-based panels tested. Drywall is notably weak in fastener retention (68–100 lbf under comparable testing per ASTM C473), which is a significant limitation in applications requiring fixture mounting, cabinetry, signage, or equipment attachment. NexBoard’s fastener pull-through performance is consistent with a high-density fiber-reinforced composite matrix and opens applications where robust fastener retention is a structural or code requirement.

NexBoard recorded a compressive strength of 5,257 psi under the ASTM D6641 Combined Loading Compression protocol — a polymer matrix composite standard. Competing panels are not polymer matrix composites and cannot be formally evaluated under ASTM D6641. For context, published APA and ASTM C473 data indicate drywall core hardness equivalent to roughly 200–500 psi under comparable loading, OSB 1,500–2,500 psi, MDF 1,800–3,000 psi, and plywood 2,000–3,500 psi. NexBoard’s 5,257 psi places it well above all estimated competitor values, confirming its suitability for structural and semi-structural applications where compressive load bearing is a requirement.

NexBoard received a perfect 5A rating — the highest possible — with no peeling or removal of its surface layer under X-cut tape testing. This indicates a highly uniform, chemically receptive surface layer that accepts paint, epoxies, urethanes, and specialty finishes without extensive surface preparation or priming.

NexBoard’s VOC content of 37.8 g/L qualifies for EPA, CARB, LEED, and GREENGUARD certification thresholds that OSB, MDF, and plywood cannot meet due to their formaldehyde-based resin binders. It significantly outperforms OSB (100–300 g/L), MDF (50–150 g/L), and plywood (50–200 g/L). Drywall’s inorganic gypsum core gives it a natural VOC advantage (10–30 g/L), though NexBoard remains well within all major compliance limits.

Under ASTM D570 (24-hour water absorption), NexBoard recorded an average water absorption of just 3.47% by weight — dramatically lower than every competing panel. Drywall absorbs 25–35% of its weight in water, causing structural failure, swelling, and mold growth. OSB and MDF absorb 10–25% and 8–18% respectively, leading to delamination and dimensional instability. MGO board and plywood absorb 8–18% and 8–15% respectively. NexBoard’s 3.47% result confirms its resistance to moisture-related failure and directly supports the case for reduced water damage insurance exposure for buildings where it is specified. Under extended 7-day immersion (ASTM D570), NexBoard absorbed just 6.06% and remained structurally sound and dimensionally stable — no comparable 7-day immersion data is published for competing panels, each of which would experience significant structural compromise well before 7 days.

Under extreme conditioning at 160°F and 97% relative humidity, NexBoard recorded 0.04% moisture absorption at 24 hours, 0.87% at 168 hours, and 0.99% at 28 days. ASTM D5229 is a polymer composite standard, so competing panels cannot be formally evaluated under this protocol. Published equilibrium moisture-content research indicates OSB would reach 20–35% moisture content, MDF 22–32%, plywood 18–28%, and MGO board 15–25% under comparable conditions, while drywall undergoes structural failure. NexBoard’s sub-1% performance confirms suitability for tropical, coastal, healthcare, and industrial environments.

NexBoard achieved a perfect score of 10 on the ASTM D3273 mold-resistance test — the highest possible rating — with no mold growth after 28 days of exposure. Standard paper-faced drywall typically scores 6–8 (roughly 20–40% surface colonization), with comparative testing showing an average near 7.33. OSB and MDF score 3–5, reflecting high susceptibility when exposed to moisture; plywood scores 6–8 and MGO board 8–9. Some specialty mold-resistant drywall grades can also reach a 10, but that is the premium tier of the drywall market — NexBoard achieves this rating as an inherent material property, without added treatment.

NexBoard showed no change after 168-hour exposure to 14 chemical reagents under ASTM D543-21. ASTM D543 is a polymer matrix composite standard; conventional building panels (drywall, OSB, MDF, plywood, MgO) are not polymer composites and are not formally evaluated under this protocol. This result confirms NexBoard’s suitability for environments with chemical exposure such as healthcare, industrial, laboratory, and commercial kitchen applications. By contrast, conventional drywall softens and disintegrates when exposed to acids and bases, and wood-based panels are susceptible to solvent attack on their adhesive and resin binder systems.

NexBoard showed no evidence of corrosion after 96 hours of salt spray exposure when evaluated with a #10 drywall screw and an 8d nail. ASTM B117 is a metal and metal coating standard; conventional building panels are not evaluated under this protocol. This result is directly relevant to fastener performance in coastal, marine, industrial, and high-humidity applications. Conventional drywall’s gypsum chemistry is known to promote fastener corrosion, and high moisture-absorbing panels (OSB, MDF) accelerate corrosion of embedded or surface-mounted fasteners in wet environments.

NexBoard achieved the highest possible rating of 10 under ASTM D3345-22 — the standard test method for laboratory evaluation of wood and other cellulosic materials for resistance to subterranean termites — with no evidence of termite attack. Subterranean termites cause an estimated $5 billion or more in structural property damage in the United States annually and are the most destructive wood-destroying insect known. OSB and plywood, as untreated wood-based products, are among the most susceptible of all building materials to subterranean termite attack; published USDA Forest Products Laboratory research and field study data confirm that untreated OSB and plywood panels receive ratings of 0 to 3 on the 0–10 ASTM D3345 visual scale — the most severe damage categories. Untreated MDF provides moderate resistance due to its resin binder density, typically scoring 4 to 6, but treated grades vary considerably. Gypsum drywall and MGO board are inorganic materials and are not formally evaluated under ASTM D3345, which is a cellulosic material standard; however, the paper and fiber facings of both products are nutritive to termites and susceptible to consumption. NexBoard’s perfect 10 rating reflects an inherent material property of its polymer composite construction — subterranean termites cannot feed on or damage a polymer matrix, making NexBoard intrinsically and permanently resistant to termite attack without the need for chemical treatment or preservative impregnation.

In an accelerated aging study conducted under ASTM G155-25 (Standard Practice for Operating Xenon Arc Lamp Apparatus for Exposure of Materials), NexBoard was subjected to 1,500 hours of full-spectrum xenon arc UV exposure simulating prolonged outdoor solar radiation. When subsequently evaluated for flexural properties under ASTM D790-25 (Standard Test Methods for Flexural Properties of Unreinforced and Reinforced Plastics and Electrical Insulating Materials), NexBoard exhibited 0.0% loss of flexural strength — and in fact recorded a slight increase in measured flexural strength by the end of the study. Testing was conducted by Right Testing Labs (Atlanta, GA), Test Report No. RTL1493-14c, issued October 26, 2026. Four baseline specimens recorded an average maximum stress of 2,496.5 psi (17.2 MPa). Four specimens were removed from the xenon arc weatherometer at 200, 500, 1,000, and 1,500 hours respectively and evaluated under ASTM D790. The post-1,500-hour specimens recorded an average maximum stress of 2,506.8 psi (17.3 MPa) — statistically equivalent to the baseline, with a degradation percentage of +0.4% to +0.5% (reflecting a slight measured increase rather than any loss). Intermediate results at 200, 500, and 1,000 hours showed percent changes of -2.8%, -0.8%, and -0.3% respectively, all within normal test variability and well within measurement uncertainty. No deviations to ASTM D790 or ASTM G155 were observed during the evaluation. ASTM G155 uses a xenon-arc lamp that replicates the full solar spectrum from ultraviolet through visible and infrared, providing a more comprehensive and realistic aging simulation than fluorescent UV methods. The 0.0% flexural strength loss result confirms that NexBoard’s polymer composite matrix, including its Durazite™ surface layer, is inherently resistant to UV-induced degradation — a material property that does not diminish over time and does not require additional UV-protective coatings or treatments. ASTM D790 and ASTM G155 are polymer matrix composite standards; conventional building panels including drywall, OSB, MDF, and plywood are not polymer composites and are not formally evaluated under these protocols. Published accelerated aging studies on wood-based panels under the applicable ASTM D1037 wet/dry cycle protocol document flexural strength losses of 15–40% for OSB, 20–50% for MDF, and 10–30% for plywood following accelerated aging. Gypsum drywall undergoes structural dissolution under moisture-based aging and is not UV-tested under ASTM G155. NexBoard’s perfect 0.0% strength retention represents a fundamental durability advantage with direct commercial relevance for coastal, high-humidity, exterior-exposure, and long-lifecycle construction applications.

NexBoard is manufactured from 100% recycled materials — post-consumer and post-industrial — and qualifies across multiple green building certification programs, including LEED and GREENGUARD. At end of life, NexBoard is fully recyclable through standard material streams and generates none of the hydrogen sulfide disposal hazards associated with gypsum drywall in landfills — a meaningful distinction from most competing panel products.

Conventional gypsum drywall poses significant environmental challenges at disposal. When drywall enters landfills, the gypsum core can generate hydrogen sulfide gas — a toxic compound — through anaerobic decomposition in the presence of organic material. Many municipalities have enacted or are considering restrictions on drywall in standard landfills as a result. Drywall is also difficult to recycle in practice due to paper facing contamination and regional availability of recycling facilities.

OSB, MDF, and plywood are manufactured with formaldehyde-based resin binders (urea-formaldehyde in MDF; phenol-formaldehyde and MDI in OSB and plywood). These resins continue to off-gas formaldehyde and other VOCs over the product’s service life, contributing to poor indoor air quality. At end of life, resin contamination prevents these panels from being recycled through standard wood streams, and combustion for energy recovery releases toxic byproducts. None of these products carry meaningful green building certifications in standard formulations.

Magnesium oxide board has a moderate environmental profile — it does not use formaldehyde binders and is inorganic, reducing some disposal concerns. However, MGO production is energy-intensive, and the product offers no recycled content. End-of-life recyclability is limited and lacks established recycling infrastructure in most markets.

No single competitor panel matches NexBoard across all tested performance categories. NexBoard is the only product in this comparison that simultaneously achieves a Class A fire rating, passes NFPA 286, delivers competitive thermal resistance, exceeds ASTM C1629 Level 3 impact thresholds (345 ft·lbs soft body / 225 ft·lbs hard body), records an Izod impact resistance of 86.74 J/m, reaches 5,257 psi compressive strength, attains a perfect 5A surface layer adhesion, meets all major VOC thresholds, records the lowest water absorption (3.47% at 24 hours / 6.06% at 7 days), holds under 1% moisture absorption at 28 days under extreme heat and humidity (ASTM D5229), shows no change after 168-hour exposure to 14 chemical reagents (ASTM D543-21), shows no fastener corrosion after 96 hours of salt spray (ASTM B117), earns a perfect 10 mold-resistance rating, achieves the highest possible termite-resistance rating of 10 under ASTM D3345-22 with no evidence of attack — an inherent property of its polymer composite construction, requiring no chemical treatment or preservatives — and demonstrates 0.0% loss of flexural strength after 1,500 hours of full-spectrum xenon arc UV exposure per ASTM G155-25, confirming complete UV durability with no measurable degradation, all while being manufactured from 100% recycled materials with a fully circular end-of-life profile.
