"Superior Modified Bitumen Systems" fireguardSBS "Reliability with Safety" · Underwriters, Warnock Hersey Class A membrane without need for gravel, rock or emulsion· Choice of 2, 3 or 4 ply construction· Option of hot asphalt, cold adhesive or torch application· Available in 6 colorspdf spec sheet USAGE: fireguard SBS is used as cap membrane in projects requiring the protection of a fire rated system. STORAGE: Material should be stored on end, in a dry location. Assure that materials are kept clean, and away from excessive heat or cold; do not remove labels or tear off protective covering until ready for application; store in an enclosed area where temperature is above 50° F and below 90° F. Materials should not be stored more than two high without protective bracing. APPLICATION All roof decks shall provide positive drainage, and sloped to prevent ponding water. A minimum slope of ¼" per foot is recommended by ARMA (Asphalt Roofing Manufacturers Application) and UBC (Uniform Building Code, section 3207.A). Drains and outlets should be installed to remove water completely from the roof surface. All decks must be firm, solid, free of sharp edges or depressions, free of moisture or effects of freezing, free of dust or debris and capable of supporting all anticipated deck loads. Guidelines - Hot Asphalt Application: Hot asphalt application is not recommended when ambient temperatures are below 50° F, as asphalt temperature can quickly drop below the minimum point of application temperature of 425° F. Residual moisture in the substrate and roofing materials can be trapped in the system and can cause blistering. Do not apply roofing during precipitation, or when decks are wet from water, snow or frost. Do not kick out rolls into hot asphalt. Keep application rate of hot asphalt to a nominal rate of 25 lb. per square. Guidelines - Cold Adhesive Application: Cold adhesive application requires special precautions. Cold process application is NOT recommended when ambient temperature is below 50° F, as lap cure time can exceed 15 hours. Temperatures above 60° F are ideal for expediting lap cure time. Roofing should not be applied if precipitation expected prior to completion of lap cure, or when water, snow or frost is present. Keep open flames of torches away from adhesive fumes. Keep roof traffic to a minimum for 7 days until the adhesive sets and system surface firms. Caution should be exercised by other trades to avoid damaging the membrane as they proceed with their work. Cold adhesive must be applied at a rate of 1 ½ gallons per square. Excessive adhesive will damage the SBS membrane. Wood, Plywood, Lightweight Concrete, Poured Concrete and Insulation Starting at low point of the roof, apply the modified SBS cap sheet perpendicular to the slope in a shingle fashion, with a minimum 3" side laps and 6" end laps. A flow of about ¼" bitumen must be obtained around all seams. Offset end laps a minimum of 36". For slopes of 1"-2" per lineal foot apply material parallel to slope; back nail head laps 2" from the edge, 6" o.c. and side laps 8" o.c. All side laps must be staggered 18" between successive plies. TECHNICAL SERVICES Latest copy of MBTechnology's specification manual must be referenced prior to any application.
