What level section is Section 07 81 23 - Intumescent Mastic Fireproofing considered in the MasterFormat numbering structure?

In the MasterFormat numbering structure created by the Construction Specifications Institute (CSI), different levels are used to categorize sections for better organization and clarity. A Level 3 section would be used for a general classification that is broken down into more specific sections at Level 4.

Intumescent Mastic Fireproofing falls under the category of protective materials and treatments, specifically related to fire protection systems. Since it gets a dedicated section defined in the MasterFormat, it is classified as a Level 3 section, which is focused on the general area of fire-resistant materials. This classification allows for the inclusion of more detailed product information and specifications at the subsequent Level 4 section, which would provide further details on the specific types of fireproofing products and their applications.

Thus, identifying Section 07 81 23 as a Level 3 section helps in understanding its role and placement within the broader framework of construction specifications, paving the way for specific materials and methods to be outlined at Level 4.
