In one embodiment, ground mineral wool is added to conventional polyurethane foam composition Part A or Part B to improve fire or flame resistant properties. In a second embodiment, a larger percentage of ground mineral wool is used in combination with a higher water concentration in order to substantially reduce the hydrocarbon content of the resulting foam. In a third embodiment, a foam composition is substantially re-formulated to reduce polyol concentration. Preliminary testing has suggested that it is possible to create an effective foam-like insulation without requiring the "foam" components to have a high polyol concentration.
