Metal Roofing Insulation
Flute Fill (FL) is custom cut foam used for retrofit applications for metal roofs that are being covered with a new roofing system. The flute fillers are made from rigid, closed cell Expanded Polystyrene (EPS) insulation offering cost effective performance. Adding flute fill insulation in between metal roof’s standing seams provides additional rigidity and R-value to the new roof, reducing the amount of insulation needed above the flutes. Shape and size of foam is custom manufactured for the specifics of each project for virtually limitless possibilities.
