Fire Retardant (FR) Slipsheet

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

  • FR-10: These coated-glass fiber mats are 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. learn more.
  • FR-50: FR-10, FR-50 is formulated for use over wood decks or polystyrene insulation. It incorporates a heavier glass mat than FR-10 to provide enhanced fire performance. learn more.
