the styrofoam may be very flammable
and thus might be unsafe and violate codes
there may be a better (flame retardant & ok with code) material
You mean like Styrofoam? The Dow brand of StyrofoamŪ used for
insulation is always flame retardant. Styrofoam is a registered
trademark for their brand of extruded polystyrene foam
The packaging material may or may not be as there is no requirement to
be flame retardant. That material is properly called expanded
polystyrene. Material used for food contact is NOT flame retardant, but
anything used for construction, insulation of an appliance MUST be
modified. It is treated with bromides that will stop the burning if the
source of ignition is removed.
