ACFoam® Nail Base Roof Insulation

Nailable Polyiso InsulationAtlas nailable foam roof insulation is well established in the building materials industry through its ACFoam®family of products. The cores of these insulation panels are polyisocyanurate (polyiso) foam; the most widely used and accepted rigid insulation in use today. It is estimated that 60-65% of all commercial new or re-roofing applications nationwide use polyiso. Rigid polyiso is a safe, cost-effective, sustainable and energy efficient construction material.

ACFoam® Nail Base is offered in a variety of composite thicknesses, providing long-term thermal resistance (LTTR) values from 6.3 to 24.2. It combines the benefits of a nailable roof substrate and thermally efficient polyiso insulation in an easy one-step installation. For your convience, these insulation panels are suitable for multi-layer assemblies when installed over Atlas ACFoam®-II, -III or -IV and through-fastened with Atlas Nail Base Fasteners.
