To qualify for use under Section of the 2015, 2012, 2009 and 2006 IBC, a thermal barrier is not required for foam plastic insulation that is part of a Class, B, or C roof-covering assembly, provided the assembly with foam plastic insulation complies with FM 4450 or UL Fasteners Fasteners used to mechanically fasten insulation and membranes to the roof deck, shall be corrosion resistant and shall be one of the fasteners identified in Note 2 in the ppendix of this Report. 5.5 dhesive The adhesives used for adhering, or membranes to the insulation or roofing substrate shall be used as noted in the ppendix of this Report. 5.6 sphalt Hot roofing asphalt, when specified in the roofing assemblies shall conform to STM D312, Type III or Type IV. 6. INSTLLTION Firestone single ply membranes shall be installed in accordance with the applicable code, this report and the manufacturer s published installation instructions. The membranes shall be installed in accordance with Section of the 2015, 2012, 2009 and 2006 IBC or Section R of the 2015, 2012, 2009 and 2006 IRC as applicable, except as noted in this report. The manufacturer s published installation instructions shall be available at all times on the jobsite during installation. The slope of the roof on which the membranes are installed shall be a minimum of 1/4:12 (2% slope and shall not be more than the maximum slope indicated in UL Online Certifications Directory Roofing Systems (TGFU) and in the ppendix of this Report. Penetrations and terminations of the roof covering shall be flashed and made watertight in accordance with the requirements of the membrane manufacturer and applicable code. 6.1 Firestone, and shall be installed in accordance with Firestone Building Products published installation instructions.

4 6.2 System attachment requirements for wind load resistance are set forth in ppendix 1. = imum Design Pressure is the result of testing for wind load resistance based on allowable wind loads. 6.3 For mechanically fastened membrane systems (Type D) over profiled steel deck, membrane shall be installed running perpendicular to steel deck flutes. 6.4 For InvisiWeld installations, care shall be taken to ensure that the InvisiWeld Plates do not line-up with seams in the TPO membrane. This condition precludes proper induction welding of the membrane to the InvisiWeld Plates. 7. FIRE CLSSIFICTION 7.1 New Construction: Roof assemblies utilizing Firestone, or TPO membranes are described in UL Online Certifications Directory Roofing Systems (TGFU) File R9516 and in Tables provided in the ppendix. 7.2 Reroofing: The existing roof shall be inspected in accordance with the provisions and limitations of Section 1510 of the 2015, 2012, 2009 and 2006 IBC or Section R907 of the 2015, 2012, 2009 and 2006 IRC, as applicable. The existing deck shall be inspected to verify that the structure to be reroofed is structurally sound and adequate to support and secure the roofing membrane. Prior to installation of new roof coverings, inspection by and approval from the code official having jurisdiction is required. Firestone, or membranes may be installed over existing Classified Class, B or C roofing systems as described in the UL Product Certification Category for Roofing Materials (TGFU) File R9516, under the heading of Maintenance and Repair. 8.
