Key Features:
- Closed-cell EPS: Superior closed-cell, lightweight expanded polystyrene engineered for roof applications.
- ASTM C578 option: Upon request, manufactured to meet or exceed ASTM C578, the standard for rigid cellular polystyrene thermal insulation.
- Stable R-value: Offers long-term, stable R-value with excellent dimensional stability.
- Water resistant: Closed-cell EPS provides water resistance and compressive strength.
- Flute-fitting cuts: Available taper-cut, square-cut, or custom-cut to fit the bottom of metal roof flutes.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Flute fill is the key to a flat, thermally continuous substrate when re-covering metal roofs. Confirm the flute width and depth before ordering—this 9-11 in. profile suits wider flutes—and specify taper-cut pieces when the roof has a taper requirement. Cut EPS with a fine-tooth or hot-wire tool for tight fits, and keep it out of direct sun until covered.
EPS is combustible; keep it away from ignition sources and hot work until the roof covering is installed.
Order InsulFoam #1 EPS Flute Filler to prepare your standing seam metal roof for re-covering.
