Closed cell foam polyiso insulation is the product of choice for energy-aware architects, specifiers, builders, owners and consumers. Ideally suited for Fabral standing seam roofs, ACFoam®-III Polyiso Roof Insulation can be used without a thermal barrier. Easily integrated with a Fabral metal roof system, it reduces thermal conductivity and satisfies specification requirements across a wide range of roofing applications. Polyiso insulation is used in 65% of today’s new and re-roofing projects.

  • Polyiso offers the highest R-value per inch of any rigid foam board insulation. Thermal performance is measured using derivative of the R-value known as the Long Term Thermal Resistance (LTTR) Method. LTTR is a 15-year time-weighted method based on customer’s insulation needs; available values range from 5.6 to 27.3. As the value increases, so does the performance of the insulation. (Note: R and LTTR values may be used interchangeably.)
  • Polyiso has the highest level of inherent fire resistance of all foam plastics. Performs exceptionally well in three key fire tests (ASTM E84, NFPA 285 and NFPA 286/UL 1715).

ACFoam® CrossVent®:  The ACFoam® CrossVent® insulation board consists of a closed-cell polyiso with 1.0″, 1.5″, or 2.0″ vent spacer strips. The spacer strips on the insulation board allow for constant airflow that provides thermal resistance through the air space by helping to dissipate heat buildup beneath the OSB.

ACFoam Nail Base:  ACFoam Nail Base Insulation has a 7/16″ OSB applied to the foam providing a firmer surface and additional support for installation.

Atlas Nail Base Fastener link

ACFoam Nail Base Fasteners:  Atlas Nail Base Fasteners are specially engineered fasteners for installing ACFoam® CrossVent®, CrossVent® RB and Nail Base Insulation, and are required as a part of the Nail Base Insulation System.
