TECHNICAL DATA

The foam used is a modified version of Typical EPS foam widely used in the building industry specifically in the EIFES industry. “Modified” meaning the manufacturer has introduced fire retardants within so when a flame is removed from the foam the foam will self extinguish.

    We have not received confirmation of which type of #2 modified foam is supplied to us but the chart below reflects all types have a flame spread of 20.

Polyurea coating over foam (further introduced with sand in coating as it cures)

Chemline Polyurea 7061 Fire tests results. (Click here for full document)
