What Is Flute Fill EPS Roofing?

Flute fill is a high-performance roofing insulation product made from expanded polystyrene that is custom cut to fit the flutes or ribs of existing metal roof panels. The EPS boards are precisely shaped to match the unique profile of the metal roof, creating a smooth, level surface for the installation of a new single ply roofing membrane, such as Duro-Last PVC roofing, TPO, or other retrofit systems.

This approach allows building owners to upgrade their old metal roofs without the need for a complete tear off, reducing cost, labor, and disruption to business operations.

Benefits of Flute Fill EPS Roof Systems

  1. Custom Fit for Metal Roof Profiles
    Each EPS panel is engineered to match your metal roof’s exact flute dimensions, ensuring maximum coverage, a level substrate, and superior insulation performance.
  2. Exceptional Thermal Efficiency
    EPS flute fill insulation provides excellent R-value per inch, significantly improving a building’s thermal performance. In North Florida’s hot, humid climate, this means better energy efficiency, reduced air conditioning costs, and enhanced comfort inside your facility.
  3. Lightweight and Durable
    EPS is strong, moisture resistant, and lightweight making it ideal for retrofit roofing systems. It won’t absorb water or deteriorate over time, providing long term stability under the new membrane.
  4. Cost Effective Roof Retrofit Option
    Flute fill eliminates the need for costly tear offs by using the existing roof structure as a base. This reduces landfill waste and lowers overall project expenses while extending the roof’s life expectancy by decades.
  5. Ideal for Duro-Last and Other Single Ply Systems
    When paired with a Duro-Last PVC roofing system, flute fill EPS insulation creates a seamless, energy efficient roofing assembly that performs exceptionally well under Florida’s intense UV exposure and heavy rainfall.

Applications for North Florida Commercial Roofs

Flute fill EPS roofing systems are a smart choice for a variety of commercial and industrial structures, including:

  • Warehouses and manufacturing facilities
  • Retail centers and strip malls
  • Office buildings and multi-tenant properties

  • Hotels and hospitality buildings

Because the EPS panels can be custom engineered for any metal roof profile, they’re a flexible solution suitable for both large and small projects.
