EPS Physical Properties

Physical Properties of Insulfoam Expanded Polystyrene, EPS

FEDERAL SPECIFICATIONS: PRODUCT MEETS ASTM C578 (SUPERCEDES FED SPEC HH-I-524C)

Building Code Classification - ICBO Research Report No. 4169 Factory Mutual No. 4450

Surface Burning Characteristics (UL File R5212) B.R.Y.X.

½ - 5 in. Thick +

Flame Spread: 15# ; Smoke Developed 150-300#

+ - Installed in a thickness, or stored in an effective thickness, as indicated, for a density of 1.0 to 2.0 lb/cu ft

# -Flame spread & smoke developed recorded while material remained in the original test position. Ignition of molten residue on the furnace floor resulted in flame travel equivalent to calculated flame spread index of 125 and smoke developed index of over 500.

Adjoining Materials Warning: EPS is subject to attack by liquid solvents or by most solvent base adhesives and other liquid products such as gas, diesel, etc. Care should also be taken to separate any coal tar pitch products or coal tar pitch vapors from any direct contact with EPS foam.
