Lightweight, Efficient, and Reliable EPS Flute Fillers

EPS Flute Fillers are a cost-effective solution for filling the flutes of steel bridge and roof decking. Manufactured from recycled expanded polystyrene (EPS), flute fillers create lighter, more efficient structures without compromising strength or performance. Whether used in bridge construction or commercial roofing, EPS flute fillers improve insulation, provide a stable surface, and block unwanted intrusions into building cavities.

What are EPS Flute Fillers?

Foam flute fillers are designed to fit into the corrugations of steel decking. In bridge construction, EPS flute fillers reduce the overall weight of the deck while maintaining structural integrity when reinforced with concrete. In roofing, flute fillers improve energy efficiency by adding insulation and creating a flat, walkable surface for installing rigid insulation boards.

Geofoam America is a leading supplier of EPS flute fillers for bridge deck manufacturers and commercial roofing projects nationwide.

Looking for a lighter, more efficient way to fill steel decking flutes?

EPS flute fillers provide dependable performance for bridge decks, commercial roofs, and exterior overhangs. Their lightweight design speeds installation while delivering energy efficiency and long-term durability.

EPS flute fillers are manufactured from recycled expanded polystyrene foam. Some overhang applications use short polyethylene plugs designed to block openings in exposed roof decking.

By filling the corrugations in steel bridge decking with lightweight EPS, flute fillers displace heavier concrete. This reduces the overall deck weight while maintaining the reinforced concrete’s structural strength and integrity.

Yes. When used in commercial roofing, EPS flute fillers add insulation value and help create a flat surface. This makes it easier to apply rigid insulation boards and improves the building’s overall energy efficiency.

EPS flute fillers are highly durable and resist moisture, decay, and fungus. For roof overhangs, polyethylene flute filler plugs are used to block voids, preventing birds, rodents, and other pests from entering building cavities.

EPS flute fillers are commonly used for bridge decks and commercial roofs, while polyethylene flute filler plugs are used for exposed roof overhangs. Both types are manufactured to fit specific flute profiles for an exact fit.

Yes. EPS flute fillers can be custom-cut to match the unique profile of bridge or roof decking flutes, ensuring a precise, secure installation.
