Polyiso Roof Insulation Products

ACFoam® is designed for roof assemblies that depend on compatibility

In a commercial roof system, insulation isn’t working alone up there. It has to integrate with the membrane, cover board, drainage design and other roof system components. ACFoam polysio roof insulation products are engineered to deliver broad assembly compatibility and solutions for a range of commercial roofing applications.

It is used in both new construction and re-roofing projects where consistent installation and long-term performance are required.

Polyiso Wall Insulation Products

EnergyShield® delivers continuous insulation across the building envelope

Wall systems do their best work when insulation performance stays consistent across the building envelope. EnergyShield wall insulation products create a continuous thermal layer across exterior walls, foundations and under-slab applications in both residential and commercial construction.

Choosing the Right Insulation Product

There is no one-size-fits-all answer when it comes to insulation products. The right choice depends on the assembly, the application and the performance goals for the building.

That is why Atlas products are organized around real system needs, making it easier to identify the right solution for roof performance, wall performance, below-grade applications and tapered drainage design.

Application: Atlas Product: Designed For:
Commercial roofing ACFoam Flat roof insulation assemblies
Tapered roofing Tapered ACFoam and Sureslope Tapered roof insulation and prefabricated drainage solutions

Efficiency Extends Beyond the Materials

Sustainable insulation products play a long-term role in how a building performs throughout its lifecycle.

A more efficient building doesn’t happen in one big move. It comes from smart decisions made throughout the assembly. Insulation is one of those decisions.

Atlas polyiso insulation products help reduce energy loss through the building envelope, supporting steady thermal performance and more consistent interior comfort over time. They are manufactured without CFCs, HCFCs, or HFCs, and have zero ozone depletion potential (ODP) and negligible global warming potential (GWP).
