What is the minimum allowable average thickness for a beam that requires 48 mils of TFIFRM thickness?

When determining the minimum allowable average thickness for a beam that requires a specified thickness of 48 mils of fireproofing, it is essential to adhere to industry standards and regulations governing fireproofing applications. The specified thickness represents the minimum effective layer needed to provide the necessary fire resistance.

Choosing 100% of the specified thickness means that the average thickness of the applied fireproofing must meet or exceed the 48 mils requirement. This is critical because applying less than the specified thickness could compromise the fire-resistance performance of the system, leaving the structural element vulnerable in case of a fire.

Maintaining the thickness at 100% ensures that the product functions as intended and meets safety regulations. Therefore, achieving at least the required thickness is vital for compliance, optimal performance, and overall safety in fireproofing applications.
