ACFoam® Composite/PB Product Description
- Closed-cell polyiso bonded to 1/2" perlite on the top and a fiber-reinforced felt facer on the bottom.
- Perlite top eliminates the need for cover boards or vented base sheets normally recommended over foam insulations.
- Typically specified for BUR and modified bitumen systems. Consult membrane manufacturer for specific system details.
- Available in 4' x 4' (1220mm x 1220mm) and 4' x 8' (1220mm x 2440mm) panels.
- CFC-, HCFC-, and HFC-free foam blowing technology with zero ozone depletion potential (ODP) and zero (negligible) global warming potential (GWP).
- Polyiso is the highest R-value per inch insulation 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.
