ACFoam® Nail Base Roof Insulation Panels

Nailable Polyiso InsulationDiscover the power of polyiso insulation panels. Atlas nailable foam roof insulation is well established in the building materials industry through its ACFoam® family of products. The cores of the roof 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.

Offered in a variety of composite thicknesses, providing long-term thermal resistance (LTTR) values from 6.3 to 24.2, ACFoam® Nail Base combines the benefits of a nailable roof substrate and thermally efficient polyiso insulation in an easy one-step installation. For your convenience, 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. And it is typically installed over sloped solid wood and metal roof decks. Common roof systems that this nailable insulation is used on include asphalt shingles, standing seam metal, tile, and slate.
