EPS Roofing Applications
- Low-Slope Roofing
- Tapered Systems
- Reroofing & Retrofit
- Steel, Concrete, and Wood Decks
- Flute Filler
- Custom Cuts
Flat and Low Sloped
Flat EPS insulation boards provide a continuous thermal layer in flat and low-slope roof assemblies, delivering lightweight, cost-effective insulation with stable long-term R-value performance.
Tapered
Tapered EPS insulation is custom cut to create positive drainage in flat and low-slope roof assemblies while adding lightweight, long-term thermal performance.
Standing Seam
Standing seam EPS insulation provides a lightweight, continuous thermal layer for energy-efficient metal roof assemblies and sloped roof systems.
Flute Filler
EPS flute filler is custom cut to fit existing metal roof flutes, creating a smooth, level substrate for a new roof system while adding lightweight thermal performance.
EPS for Roofing
Expanded Polystyrene (EPS) roofing insulation remains a trusted choice for commercial and low-slope roofing because it delivers reliable thermal performance, jobsite efficiency, and strong value per inch. Its lightweight nature, customizability, and long-term stability make it well suited for both new construction and reroofing applications.
For projects requiring higher thermal performance in reduced thickness, GPS insulation offers an efficient next step.
Terrafoam EPS
Closed-cell EPS insulation for flat, sloped, and tapered roofs with stable R-value, no long-term thermal drift, and 10 to 20.4 psi strength.
Chrome GPS
Graphite-enhanced insulation delivering a stable long-term R-5.0 per inch at 10°C and compressive strengths from 10 to 30 psi.
