Is there any difference in its structural strength and fire performance compared to regular panels?

A: Structural Strength: Basically the same as regular PE core panels of the same thickness and coating quality, meeting installation requirements.
Fire Performance: Its decorative core is typically still polyethylene (PE), so standard Broken Core panels are NOT fire-resistant. For fireproof requirements, a specially customized fire-retardant broken core is needed (costly, less common), or it should be limited to indoor use.
