Shinwoong panels are engineered from a recycled mineral core — not coated, not laminated, not flammable. The same material performs across wall, ceiling, and floor assemblies, indoors and out.
Spec'd for architects & general contractors building in wildfire-exposed, code-critical, and healthcare-adjacent zones nationwide.
* Illustrative performance category referencing standard test methods (ASTM E84, ASTM E136) and California Building Code Chapter 7A for wildland-urban interface construction. Confirm the current certification listing, rated assembly, and jurisdiction-specific approval for your product line and finish with a Shinwoong USA specification engineer before issuing for construction.
Conventional fireproofing treats a combustible substrate so it resists ignition longer. Shinwoong starts from a core that was never combustible to begin with — the fire performance is a property of the material, not a coating applied to it.
* Nominal figures shown for illustration of the layer system. Actual thickness, weight, and finish vary by product line (wall / ceiling / floor) — see individual spec sheets for exact tolerances.
The same non-combustible mineral core, engineered to three different mounting and load conditions — so the fire performance doesn't change when the assembly does.
A side-by-side look at core composition, install economics, and long-term risk — framed as illustrative estimates so your team can verify against project-specific conditions.
| Property | Shinwoong Panel | Conventional Board |
|---|---|---|
| Core material | Non-combustible mineral composite, recycled | Gypsum or coated wood-fiber substrate |
| Combustibility | Material itself is non-combustible | Coating/treatment only — substrate can burn |
| Heavy metals · asbestos · radon | Zero, verified by batch* | Trace risk in some legacy formulations |
| Off-gassing (VOCs) | None detected in core* | Common in adhesives & surface coatings |
| Antibacterial surface | Integrated, standard | Not standard — requires added treatment |
| Recycled content | Up to 68% by core weight* | Typically low or none |
| Install time / 100m²* | ≈ 2 crew-days* | ≈ 3–4 crew-days* |
* Figures are illustrative estimates for comparison purposes only, based on typical multi-layer fireproofing assemblies. Actual performance varies by project scope, assembly design, and code jurisdiction — confirm with a Shinwoong USA specification engineer before use in a bid or submittal.
California's WUI codes (Chapter 7A) exist because embers — not just flame fronts — ignite most structures lost in wildfire events. Cladding, soffits, and eaves need to resist ignition on their own, without relying on a coating that degrades over time.
Because the Shinwoong core is inorganic by composition, it doesn't rely on an intumescent or fire-retardant treatment that can wear, weather, or be compromised during install. The same panel line is being specified for both new construction and post-fire rebuilds across ember-exposed regions.
* Illustrative relative specification-activity index by region, indexed to 100 = highest observed demand for ignition-resistant exterior assemblies. Not a fire-hazard severity rating. Confirm local WUI designation and code cycle with your jurisdiction's building department.
