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.
