What is the minimum allowable thickness for TFIFRM?

The minimum allowable thickness for TFIFRM (Thin Film Intumescent Fire-Resistive Material) is based on ensuring that the material provides adequate protection in the event of a fire. The specification requires that the thickness must be at least 80% of the specified thickness to ensure effective performance and compliance with fire safety regulations. This ensures that the fireproofing material will adequately insulate structural elements and prevent structural failure during a fire scenario.

Adhering to the minimum thickness requirement is crucial because insufficient thickness could lead to a failure in the fire-resistive protection, potentially compromising the safety of the structure. Thus, maintaining at least 80% of the specified thickness ensures that the fireproofing will perform as intended under extreme conditions.
