Atlas Roofing Corp., Atlanta, has introduced FR 10 and FR50 fire retardant slipsheets to enhance the overall fire performance of many conventional commercial roof systems. The slipsheets are coated-glass fiber mats specifically designed for installation over wood decks or combustible insulation. The FR50 incorporates a heavier glass mat than FR10 to provide enhanced fire performance with a single layer. Both products are recommended as part of a Class A assembly over combustible and noncombustible decks, extruded polystyrene, and molded EPS. Lightweight and easy to handle, the slipsheets should be rolled out with a minimum 2-inch sidelap and endlap in accordance with the membrane manufacturer's specifications.
