Refer to Product Data Sheet for long-term thermal resistance (LTTR) values.
Flat insulation available in 4ft x 4ft (1220mm x 1220mm) and 4ft x 8ft (1220mm x 2440mm) panels.
Tapered insulation available in 4ft x 4ft (1220mm x 1220mm) panels with 1/8" (3mm), 1/4" (6mm) and 1/2" (12mm) per foot slope.
Manufactured using CFC-, HCFC- and HFC-free foam blowing technology with zero ozone depletion potential (ODP) and virtually no (negligible) global warming potential (GWP).
Contains between 59% and 27.6% recycled content by weight (Atlas Technical Bulletin: TB-2).
Typically specified for use in new and re-roofing applications. ACFoam®-II is used in built-up (BUR), modified bitumen, metal, ballasted single-ply, mechanically attached single-ply and adhered single-ply roofing systems. These roofing systems depend on proper installation for successful performance. Refer to FM Approvals® RoofNav and UL Online Certifications Directory for additional application details.
To minimize the effects of thermal bridging, Atlas strongly recommends the use of multiple layers when the total desired or specified R-value requires an insulation thickness greater than 2.7” thick.
