drainage, sufficient to drain roof completely within 48 hours after a rain, 1/4:12 minimum slope of roof membrane is recommended. Roofdecks over which Foamular 404 Insulation is installed should provide an adequate fire barrier as required by the building codes. Warnin2:Combustible Foamular 404 Polystyrene Insulation will ignite if exposed to fire of sufficient heat and intensity, although it does contain aflame-retardant additive to inhibit ignition from small fire sources. This product should be installed only above a thermal barrier systemacceptable to the building codes. For example, 5/8" thick gypsum board or I" thick perlite concrete beneath the insulation (on the roofdeckside), is often acceptable. During shipping and storage, installation and use, this product should not be exposed to open flames orignition sources.Contour Taoer Tile X: Foamular Insulation is practical for building roofs having normal roof temperature conditions but should notbe used in contact with chimneys, heater vents, steam pipes, or other surfaces where tcmperatures exceed 150 degrees F. It is notrecommended for unballasted applications where sustained roof temperatures exceed 165 degrees F. and intermittent temperatures exceed180 degrees F.Foamular Insulation is recommended essentially for flat roofs. Slope limitations are dependent upon details of the system to be used.Consult the system supplier/installer. Foamular Insulation is not recommended directly over steel roof decks. Plastic or oil-base roofcements, asphalt or coal tar pitch are not recommended with Foamular Insulation. Lt. Deck Board: Light wt. concrete deck applicatorshould sptcify size and number of key/vent holes.13. FIRFSfONE BUILDING PRODUcrs, INC.ISO 95 + and Rhoflex Isocvanurate: UL Class A, FM Qass I, I-fJJ or I-W. Firestone roof insulation products are non-structural, non-loadbearing materials. They are not designed for direct traffic usage unless adequately protected. All roof insulation should be kept dry andprotected from the elements. Asphalt mopping temperature must not exceed 450 F. No more insulation should be installed than can becovered in the same day. Isocyanurate foam will burn if exposed to a flame of sufficient heat and intensity. Contact Firestone for adviceon the use of these products if there is any doubt concerning the proper product for the job, the proper installation procedure or the propercode approvals.Composite Roof Insulation: UL Qass A, FM Qass I, I-fJJ or I-W.

GAF CORPORATIONGaftemp Isotherm R: Gaftemp Isotherm R roof insulation is a non-structural, non-loadbearing material. It is not designed for direct trafficusage unless adequately protected. Gaftemp Isotherm R roof insulation should be stored dry and protected from the elements. No moreinsulation should be installed than can be completely covered with roofing on the same day. As unprotected urethane will burn, fire safetyprecautions should be observed wherever any isocyanurate products are used. Gaftemp Isotherm R is an insulation board made up ofcomposite mat facers bonded to a core of isocyanurate foam.Gaftemp Perlite: UL Desim Numbers: POOl, POO4, P20I, P206, P2IO, P2II, P22I, P224, P225, P230, P232, P233, P237, P238, P243, P502,P508, P5IO, P70I, P708, P7IO, P80I, P803, P805, P8IO, P814, P815. Limitations and Restrictions: Gaftemp Perlite roof insulation shouldnot be left exposed to the weather. Gaftemp Perlite insulation products are not recommended for continuous use at temperatures over200 F. All insulation boards must be maintained in a dry condition prior to installation. For ambient temperatures below 40 degrees F,the use of hot bitumen application is not recommended due the rapid cooling of the bitumen. Direct torchin2: GAF does not recommendthat modified bitumen roof membranes be directly torched to any insulation. A base sheet should be applied to the surface of theinsulation and the torchable membrane torched to the base sheet.Mechanical Fasteners: GAF recommends the use of Gaftite Sentri Coated or Stainless Steel mechanical fasteners for the attachmentof Gaftemp roof insulation products to steel decks. The correct number and type, per the Factory Mutual Approval Guide, should be used.Limitations: The values listed herein are typical, nominal values obtained under laboratory conditions using industry-standard test methods.These values are subject to change at any time without notice.15.
