The hourly rating applies only to the complete system. The perimeter fire containment system consists of protecting the exterior wall as well. The individual components are not assigned a rating and are not to be interchanged between systems (i.e. manufacturer's components from one system being used to replace another manufacturer's components in a separate system). 2 Section 715.4 of the 2015 IBC requires an "approved" perimeter fire containment system tested in accordance to ASTM E2307. Every building has unique design details that may not exactly match the system details published. The IBC recognizes that there may be variations per individual buildings that may require adjustment via engineering judgments 4 and therefore enables "approval acceptable to the building official". Engineering judgments are typically based on testing, or data from similar perimeter fire containment system tests, or other evidence and third party engineering judgments that the proposed system meets the basic principles necessary for perimeter fire containment systems. 3 Install a reinforcing mounting angle from the floor edge to the stud framing in the safing area. Although that is a typical structural detail commonly used to secure the framing to the building structure, the stiffener in conjunction with the angled steel strut also reinforces the studs against bowing during fire exposure, and insures that the compression fit of the Owens Corning Thermafiber Safing Insulation will be secure. 4 Typically Owens Corning Thermafiber Safing Insulation is to be a minimum of 25% compression fit between the slab edge and the wall system. Compression of the Safing Insulation creates a tight seal that maintains its integrity preventing flame and hot gases from breaching through to the floor above. 5 Apply the Approved Smoke Sealant to the top of the Safing Insulation to make the system smoke tight. The smoke sealant is commonly spray applied to the top of the Safing Insulation (non-fire exposure side). Typically a 1" over spray is specified extending the smoke seal onto the floor slab one side, and the gypsum board surface on the other, to create a continuous seal that impedes the passage of smoke.
