JMCleanBond® Cap
Johns Manville JMCleanBond SBS Cap Sheet is a fire-resistant, modified bitumen sheet incorporating the features of a strong fiber glass mat with a blend of SBS (Styrene-Butadiene-Styrene) rubber, high-quality asphalt and fire-retardant additives. The elastomeric asphaltic blend has full recovery properties after 100% elongation and lends elasticity and flexibility to the sheet. The inorganic fiber glass reinforcement provides tensile strength, dimensional stability, fire-resistance and toughness to the sheet and resists moisture absorption. The covering layer of ceramic-coated roofing granules provides durability along with superior resistance to damage from weather and foot traffic.
