EPS for Forming, Insulating, and Light-Weighting Concrete Structures
Cellofoam® EPS foam is an excellent solution for a wide variety of concrete applications, from one-time use in concrete forms to serving as permanent core insulation and light-weighting void fill in precast and cast-in-place concrete walls and floors.
For permanent concrete structures, Cellofoam EPS Foam is made of premium expanded polystyrene (EPS) rigid insulation composed of closed cells with excellent dimensional stability, flexural and compressive strength, and water resistance. The foam may be hot-wire cut to fit nearly any concrete core shape. With its high compressive strength, the EPS can handle the considerable weight of the wet concrete and provides not only light-weighting of the final product but also considerably improves R-value.
For temporary concrete forms and applications, Cellofoam EPS foam is used to create inexpensive, detailed molds to form complex concrete shapes such as curved walkways and columns. It is also commonly employed as temporary block outs for windows in concrete railings. Due to its lower cost, non-spec EPS foam is often selected for such one-time use applications depending upon needed physical properties.
Meets or exceeds ASTM C578 specs, with excellent dimensional stability & compressive strength. Very light weight. Non-spec, lower cost versions also offered for temporary forms.
The R-value of EPS is permanent because the only gas in EPS is air. Unlike Polyiso or XPS whose blowing agents outgas and therefore lose R-value, EPS R-values do not degrade over decades of use.
Cellofoam EPS contains no formaldehyde or ozone-depleting CFCs or HCFCs. It is 100% recyclable and may contain recycled material.
Cellofoam EPS is Underwriters Laboratory Listed, UL ER7260, for many building and geofoam applications.
Cellofoam EPS is quick drying and does not readily absorb moisture from the air. Its closed-cell structure reduces the absorption and migration of moisture.
Cellofoam EPS is hot wire cut to customer dimensioned drawings and is available in ASTM C578 nominal densities of 1.0, 1.25, 1.5, 2.0, 2.5, and 3.0 lb/ft3. As with all Cellofoam EPS foam building products, our EPS for concrete structures is manufactured from raw material that includes a fire retardant.
