What is the Rating per inch of Fireproofing?

Fireproofing, like all fire resistive products, does not have a rating by itself. Ratings are assigned to complete assemblies such as floors, roofs or walls which must be constructed in strict accordance with published test results in order to achieve the rating indicated. The use of fireproofing in conjunction with other components makes it possible to achieve ratings of up to 4 hrs.

What is the typical Rating required for Fireproofing?

Ratings are based on Building Code requirements and are determined based on the size of the building, its height, the number of stories, its use and whether it is sprinklered or not.

Fireproofing costs are based on many factors including the type of fireproofing used, what it is protecting and the ratings required.

Of course, costs will vary among products and uses.
