Basic, Common Factors ■ ■ Type(s) of assembly used e.g. Glass, Aluminum, Granite, Concrete ■ ■ Hourly rating required Spandrel Perimeter Fire Barrier System ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Closest Listed System upon which the EJ is based. Joint width Static or Dynamic Insulation type(s), thickness and compression, etc. Five Basic Principles • Mechanical Attachment of the Spandrel Insulation • Protection of the Mullions • Compression fitting and orientation of the Safing Insulation • Installation of a Reinforcement Member(s), stiffener, at the Safe-Off area behind the spandrel insulation. • Firestop Coating, type, thickness By following the above evaluation process for Perimeter Fire Barrier Systems’ Engineering Judgments, these can be developed in accordance with sound engineering practice to ensure that life safety and structural integrity are not compromised. SYSTEM SELECTION System selection for perimeter firestop system can be done by accessing third-party certification laboratory listing directories. One of the examples is the Intertek certification directory. The Intertek directory follows a specific nomenclature to identify the different firestop systems listed.
