What percent of specified thickness is the minimum allowable TFIFRM thickness determination?

Thickness compliance focuses on ensuring the installed fireproofing meets a defined portion of what the project specifies. The minimum allowable thickness is 80% of the specified thickness. This means the measured thickness must be at least 0.8 times what the spec calls for (for example, 1.6 inches if the spec is 2 inches). This threshold balances practical field variability and measurement limits with the need to maintain adequate fire resistance. Falling below 80% could indicate under-application that compromises performance, while requiring a stricter standard like 90% would cause unnecessary rework for minor, unavoidable deviations.
