Atlas inorganic fire retardant underlayments, or slipsheets, enhance the overall fire performance of many conventional commercial roof insulation systems, including metal roofs.

FR-10 are coated-glass fiber mats specifically designed for installation over wood decks or certain combustible insulation. The proprietary flame-retardant coating and glass fiber mat provide protection against flame spread and flame penetration through the roof system. The slipsheet can also act as a barrier between chemically incompatible insulation and roof membranes. In addition, the sheet may be used in multiple layers to achieve certain Class A fire resistance ratings.
