Be cautious of glassless mirror products claiming fire safety using only an ASTM E84 rating.
While ASTM E84 tests surface flame spread and smoke development, it does NOT certify a product as fire-retardant or fire-rated. Only trusted, independent testing laboratories like Underwriter Laboratories (UL) can provide comprehensive fire safety certification.
If a mirror product is not UL-rated, it may not meet public safety standards and could pose a fire hazard—especially in commercial, public, or institutional settings.
Look for the UL® mark and file number to ensure your product is truly certified for fire safety.
