Create a Firestop Submittal
Hilti has performed extensive testing in both through-penetration and construction joint firestop applications. However, due to variations in construction throughout the phases of a project, it is not possible to test every firestop application that may be encountered.

For these situation, Hilti has developed a process for creating custom drawings to accommodate particular applications. Hilti custom drawings, or Engineering Judgments, are developed through the careful and restricted application of accepted fire protection engineering principles and guidelines set forth by the International Firestop Council (IFC). Test data of like systems are analyzed and applied toward similar applications that do not exactly meet the criteria of a current UL Listed System.

If a current UL Listed System does not accommodate a particular application, please submit the appropriate form(s) below to request an Engineering Judgment. Once received, the requested information will be evaluated and an Engineering Judgment will be created, if possible.

For additional technical assistance, please contact our Customer Service team at (800) 879-8000.
