Poly Flute Fill

Poly Molding's Flute Fill is a cost effective method to level your metal roof or bridge deck and to stop energy loss or displace concrete.

Ribbed profiles are relied upon to generate sufficient support for roofing material at both residential and commercial buildings.  The flute is the portion of the ribs with a gap.  Our geofoam products function as flute fillers to close the gap between such spaces while simultaneously enhancing the roof’s resistance to moisture and bolstering the roof assembly’s R-Value.  Geofoam is the perfect flute filler as it is light in weight, proves strong across posterity and won’t bust your budget.

Poly Molding Expanded Polystyrene (EPS) is optimal for flute filling as it is durable, thermal resistant and can even be customized to suit the nuances of the roof in question.  Poly Molding Flute fill is suitable for roofs with varying rib sizes, shapes, and other nuances.  Furthermore, our flute fill insulation customization guarantees the ribbed space will be completely concealed without even the slightest gap.  An added benefit is the fact that flute fill come with a 20 year warranty, a true testament to the material’s reliability.  You will be hard-pressed to find another material with the same benefits as Poly Molding EPS Flute Fill

Poly Molding EPS Flute Fill is a specially engineered insulation made from high-quality, closed-cell expanded polystyrene (EPS). It meets or exceeds the requirements of ASTM C578, ensuring its superior performance as a thermal insulation material. With excellent dimensional stability, compressive strength, and water resistance, Poly Molding Flute Fill offers a long-term, stable R-Value.

Designed for use over standing seam metal roof systems, Poly Molding EPS Flute Fill is custom-manufactured to fit the flutes of the roof system. It can be taper-cut or square-cut to match the bottom of the metal roof or profile-cut to conform to the shape of the existing roof. Compliance with local building codes and consultation with the new roof system manufacturer is recommended to meet specific system requirements.

The advantages of Poly Molding Flute Fill include its versatility, cost-effectiveness, and environmental friendliness. It can be manufactured in various sizes, densities, thicknesses, and profiles to meet job-specific needs. By addressing flute spanability and minimizing the need for additional insulation, it offers cost savings and reduces the potential for raising curbs and rooftop units. Furthermore, it is environmentally friendly, containing no ozone-depleting blowing agents, potentially incorporating recycled materials, and being 100% recyclable.
