Sprayed Fire Resistive Material (SFRM), often referred to as sprayed applied fire-proofing material, is a passive fire-resistive substance applied to structural members. Its purpose is to enhance the fire resistance characteristics of these structural elements by providing insulation. The fire-resistance rating of a sprayed-applied fireproof assembly depends on factors such as the type of SFRM used, its thickness, density, and bond strength. Therefore, the field verification of SFRM installation is a crucial aspect of building commissioning.

At TAIREC Fire Consulting, our team possesses extensive familiarity and experience with the standards that underlie the testing and commissioning process for SFRM. We are well-equipped to provide valuable assistance with these services.


Listed firestop assemblies are required where there are penetrating items and/or joints in fire resistance rated walls or floors. The assembly consists of the wall or floor that is being penetrated, the penetrating item(s), the size of the opening and arrangement of the penetrating item in that opening, and the firestopping materials that protect the opening. Each listed firestop assembly has actually been fire tested in this specific configuration. There are inevitably field conditions which do not match one of the listed firestop assemblies available. This is where an engineering judgment can be a very useful and effective solution in lieu of incurring the cost of an expensive fire test. 

Tairec engineers are experienced in providing an engineering judgement by evaluating the anticipated performance of a proposed firestop assembly that has not been fire tested based on the performance of listed firestop assemblies and engineering principles.
