Roofing Applications

How Foam Is Used in Roofing Systems

Foam insulation plays a critical role in modern commercial roofing systems by improving thermal performance, supporting proper drainage, and creating consistent roof assemblies. Rigid foam boards are placed on top of the roof membrane to help manage energy efficiency, reduce heat transfer, and accommodate slope requirements for water control.
