ACFoam®-II Product Description
- Closed-cell, polyiso foam core integrally laminated to heavy, black (non-asphaltic), fiber-reinforced organic felt facers.
- Offered in a variety of thicknesses, providing long-term thermal resistance (LTTR) values from 6.0 to 25.0.
- Available in 4' x 4' (1220mm x 1220mm) and 4' x 8' (1220mm x 2440mm) panels.
- Typically specified for hot asphalt or coal tar BUR, modified bitumen and single-ply membrane systems.
- CFC-, HCFC-, and HFC-free foam blowing technology with zero ozone depletion potential (ODP) and zero (negligible) global warming potential (GWP).
- Recycled Content: Between 16% and 43% by weight, depending on thickness (57% post-consumer, 43% pre-consumer).*
- Polyiso rigid board insulation provides the highest R-Value per inch in the industry. Excellent R-Values reduce energy demands while maintaining compatibility with all types of roofing membranes and fire assemblies. See ASHRAE 90.1 Standards for Model Energy Code.
*Information About Recycled Content
ACFoam®-II roof insulation contains between 16% and 43% recycled materials by weight, depending on thickness. Since the facers are made of 100% recycled materials (57% post-consumer, 43% pre-consumer), the thinner the product, the higher the recycled content.
A double layer application of insulation with staggered joints is well known for its improved thermal efficiency (prevention of heat loss or gain) over a single layer. Just as important, a double layer can increase the level of recycled material in the total roof insulation. Refer to Technical Bulletin #03-02.

ACFoam-IV featured in a new case study set in New Orleans, LA. Find out how this great product with HIGH PERFORMANCE characteristics helped control costs and address code requirements in a local film studio. Thanks to Atlas’ innovative facer technology, Atlas ACFoam-IV is the first high performance polyiso roof insulation product capable of never-before-seen wind uplift ratings for selected roof membranes adhered directly to polyiso.
GEMINI™ Tapered Edge Strips are the only polyiso insulation component with a Zero Edge Solution. Gemini TES provides a smooth transition from tapered edge to roof surface in a dimensionally stable insulation panel for use in Single-Ply, Mod-Bit, and BUR systems. The best thing about Gemini TES is that they provide a stronger, more durable edge material than perlite or fiberboard.
