DynaGlas® FR features ceramic-coated roofing granules engineered for optimal embedment in the SBS-blend sheet. The ceramic coating promotes excellent long-term adhesion.
An SBS rubber and asphalt blend lends elasticity and flexibility to the sheet and contains fire-retardant additives. The thicker JM SBS coating provides more waterproofing value. A fiber glass reinforcement mat offers excellent dimensional stability and tensile strength and withstands differential movement.
