IntroductionThe purpose of this guide is to reinforce installation techniques. The following guide is a supplement to be used inconjunction with the other guides located within the Technical Database. Reference to the specific Design Guide,Application Guide, Detail, Technical Information Sheets (TIS), and other Specifications is necessary to ensurethat the finished roof system is installed in compliance with Firestone requirements.NOTE: IF A PROPOSED APPLICATION FALLS OUTSIDE OF THIS SPECIFICATION, CONTACT YOUR BUILDINGSYSTEMS ADVISOR AT 800-428-4511 FOR ADDITIONAL INFORMATION.Within Firestone Specifications, reference is made to Firestone’s Mechanically Attached Systems.Mechanically Attached Systems by definition include: Batten in The Seam – BITSBatten or plates in the seam of the membrane.Plates are only allowed with reinforced membranes Mechanically Anchored System (Non-Reinforced Membrane) – MASLay out sheet battens on membrane, strip in Mechanically Anchored System (Reinforced Membrane) - Reinforced MASLay out sheet, set plates or battens on membrane, strip in Reinforced Mechanically Attached Strip – RMALay out strips over insulation; attach strip using plate or battens, place membrane overthe strips.1.02 Substrate and Substrate RequirementsGeneral1.The Firestone roof system depends on a suitable substrate to perform its intended function ofweatherproofing the building.I t is t h e r oofin g con t r a ct or ’s r e sponsibilit y for e n su r in g t h a t t h e su bst r a t e is a cce pt a ble for t h e Fir e st on er oof syst e m .2.The substrate to which the Firestone roof system is installed must: Be structurally sound Be dry, smooth, flat and clean Be free of sharp fins, or foreign materials that could damage the membrane Meet the minimum requirements for the system3.When using asphalt to adhere insulation to a structural concrete substrate, the concrete must be primedwith an ASTM D 41 asphalt primer. The primer is applied at a rate of 1½ to 2 gallons per 100 ft² (0.61 to0.82 L/m²).3 Pa g eFir est one At t achm ent GuideJuly 2015

An ell is required in corner area equaling “2a”.When the roof slope is less than or equal to 10o (2:12 Slope); “h” is equal to the eave height.slope is greater than 10 (2:12 Slope): “h” is equal to the mean roof height.When the roofContact your Building Systems Advisor at 800-425-4511 for further clarification on these descriptions.5 Pa g eFir est one At t achm ent GuideJuly 2015
Adjoining Buildings6 Pa g eFir est one At t achm ent GuideJuly 2015
When a building adjoins another and has an elevation change of 3' or less then the perimeter and cornerenhancements can be omitted in that area. See the first diagram below. In the same building configuration andthe elevation change is 3' or greater, the higher building requires a standard building layout (perimeter and cornerenhancements) with the lower building omitting the perimeter and corner enhancements in that area. See thesecond diagram below.If there are concerns in regard to this enhancement, contact your Building SystemsAdvisor at 800-428-4511 for further clarification.7 Pa g eFir est one At t achm ent GuideJuly 2015
1.03 Insulation AttachmentGeneral1.2.3.Insulation must provide a suitable substrate for the proposed roof system as well as insulation for thebuilding.Insulation thickness requirements may vary for code compliance. Contact the local code or insurance officialbefore contacting your Building Systems Advisor at 800-428-4511.Refer to Insulation Technical Information Sheet (TIS) for specific spanning capabilities.At t a ch m e nt1. Insulation may be installed by various methods including fasteners, adhesives and asphalt. It is acceptableto combine fastener and adhesive attachment methods in multi-layer applications.2. Tapered insulation below the 1" (25.4 mm) minimum thickness must be fastened at a rate of one (1) fastenerand plate per two (2) ft² (0.22 sq. m). If possible, install the tapered insulation first, covered by the flat stock.3. Refer to specific Firestone Technical Information Sheets (TIS) for installation and fastening requirements.4. When a composite of two insulation layers is installed, the fastening pattern required for the top boardthickness must be used. A common fastener may be used to install multilayer applications. Some restrictionsapply to fastener length depending on standards used.Multiple Layers of Insulation1.2.Where overall insulation thickness is 2" (50.8 mm) or greater, Firestone recommends installing the insulationin two (2) or more layers.Insulation may be installed in one or multiple layer applications for the Firestone warranty. If installed inmultiple layers, the joints of each succeeding and adjoining layer should be staggered from the joints ofprevious layers by a minimum of 6" (152.4 mm) in each direction. When a composite of two insulation layersis installed, the fastening pattern required is dependant on the top board type and thickness. A commonfastener may be used to simultaneously fasten all layers to the structural deck.Mechanical Attachment of Insulation to Substrate1.2.3.Insulation must be fastened with appropriate Firestone fasteners and insulation plates.Firestone All Purpose (AP’s) fasteners are not acceptable, except for wood decks, for any 25, 20 yearsystems, 15-year re-cover, or Partial Tear off applications.Fastening rates and patterns may vary for code or regulatory compliance.

While some Firestone roof systems may require an air barrier to receive a Firestone warranty, the need for anair barrier, as well as the type, placement and location of the air barrier must be determined by a professionalarchitect or engineer.2. Air barriers systems are a component of building envelope systems that control the movement of air into andout of buildings.3. An air barrier may consist of a single material or of two or more materials which, when installed as a system,make up an air impermeable, structurally adequate barrier.4. Air barrier systems are generally comprised of building components and materials that have an airpermeability not exceeding 0.004 cfm/sf under a pressure differential of .3 in. water.5. No single component or material has the capability to provide a complete air barrier system for a building;therefore, air barrier systems include many components and materials that are interfaced with each other.Firestone recommends that the individual manufacturers of these products provide written certification thattheir products, when used together, meet this requirement.6. If the air barrier is to perform its intended role, it must meet a number of requirements: Continuity: the assembly must be linked together and sealed at all laps, seams, perimeters andpenetrations to ensure that there is no break in the air tightness of the envelope. Structural Integrity: The air barrier must be capable of resisting the imposed load or must besupported by one that can. It must be capable of resisting the strongest wind load acting as either apressure or suction without rupturing or breaking away from its support. The air barrier and its supportmust be sufficiently rigid to resist displacement. Air Impermeability: A major requirement of an air barrier is that it offers a high resistance to airflow. Durability: Durability depends largely on how a material reacts to a specific environment such asmoisture, temperature, ultra-violet radiation, and to the presence of other materials (incompatibility).9 Pa g eFir est one At t achm ent GuideJuly 2015

Immediately walk the board in and weightit down with pails of Bonding Adhesiveor other available weight.See serpentine style diagram on right.Criteria for Field Testing Insulation Adhesives for Adhesion to Deck Substrates1. Prepare an area large enough to allow a 4' x 4' insulation board to be laid in place. Follow the appropriateFirestone Technical Information Sheet guidelines for surface preparation and list of acceptable substrates.Contact your Building Systems Advisor at 800-428-4511 if the substrate information is not listed.2. Apply the adhesive to the deck per recommended application rates and methods (12" o.c., ½" to ¾" bead).3. Allow the adhesive a minimum of 60 minutes to cure.4. After the adhesive has been allowed to cure, pull up on the adhered board by placing a hand under the corner orend of the board in the same direction as the ribbons. Make sure that the board is lifted by hand. Using tools toscrape the board sometimes disbonds the adhesive from the deck. This will not show whether the adhesive isperforming under uplift considerations. (If a tool is used, it should be used to pry or pop the board up).5. Observe the insulation and deck. The desired result is a delamination of the surface or board facer with adhesiveand facer residue remaining on the deck or the board breaks apart remaining adhered to the deck at the ribbons.If the board is lifted and the adhesive pulls/peels off the deck or decking is pulled up with the board,contact your Building Systems Advisor at 800-428-4511. This will be considered an unacceptablesubstrate.12 P a g eFir est one At t achm ent GuideJuly 2015
