When it comes to selecting the best overall roof insulation product, Polyiso is the product of choice. No other insulated roofing product has the perfect combination of features that are so important for long-term performance. These features have low initial installation costs, as well as attractive life-cycle payback rates, which can be easily calculated by using the EnergyWise Roof Calculator Online (NRCA/PIMA). Ask your Atlas Sales representative for a demonstration.
Polyiso roof insulation is the only insulated roofing product that can be used in almost all types of roof systems without the need for a thermal barrier. Unlike other insulation products, Polyiso’s high-temperature stability prevents melting when mopped with hot bitumen. A polyiso roof insulation board is unaffected by properly applied construction adhesives, and many membrane manufacturers specify its use without the need for a cover board in single-ply adhered systems.
All Atlas ACFoam® polyiso insulations are QualityMarkcm certified; giving consumers an easy way to identify quality insulation products that meet or exceed listed LTTR-values. Atlas recommends ACFoam® Roof Insulation only for roofing applications installed by a qualified contractor. FM Approvals has approved the use of ACFoam® as a component in Class 1 insulated roof deck construction. ACFoam® has also been tested and Classified by Underwriters Laboratories as a component of an insulated roof deck.
Designers are required to consider several standards when determining the components of a roof assembly, including insulation products.
The following checklist is not exhaustive but should assist in the design process:
Because of its ability to resist heat transfer, polyiso roof insulation conserves energy and increases occupant comfort. These insulated roofing products are also built with recycled materials and have zero ozone depletion potential (ODP) and virtually no (negligible) global warming potential (GWP).
It also provides important roof system benefits:
Besides its many well-known benefits, including serving as an appropriate base for roof membranes, improving occupant comfort, reducing potential for condensation, and reducing operating expenses, ACFoam also provides a positive Life Cycle Assessment, a key measure of sustainability. Based on a cradle-to-grave assessment, ACFoam greatly reduces fossil fuel use and associated carbon emissions. Energy savings and carbon reductions greatly outweigh the marginal embodied energy needed for the creation, use, and disposal of the material.

Atlas insulated roofing products and the trade association representing the industry, PIMA, has received many environmental awards. These include the Sustainable Buildings Industry Council’s (SBIC) 2003 “Best Practice” Sustainability Award and the U.S. EPA’s Climate Protection Award for the association’s leadership in promoting energy efficiency and climate protection.
In 1999 the U.S. EPA also awarded Atlas the Stratospheric Ozone Protection Award for “leadership in CFC phase-out in Polyiso roof insulation and in recognition of exceptional contributions to global environmental protection.”
