ABSTRACT:
Portable apparatus is used for dispensing of urea formaldehyde foam for use as a sound and heat insulator. The apparatus includes a framework having mounted therein three valves which are simultaneously actuated by a single handle lever. One valve dispenses air to a connection downstream of another of the valves which dispenses a mixture of water, detergent, and resin hardener while the third valve controls the flow of urea formaldehyde resin. The air and water-detergent mixture are combined in a frothing chamber and together they are conveyed in foamed condition to a mixing chamber. The resin is sprayed into the mixing chamber to combine with the froth and the resulting mixture is propelled into a cavity which will house the insulation.
