ABSTRACT:
A method of making an insulation product to be used as a thermal resistor and fire retarder, and also to an apparatus for the accomplishment of this process. This method involves the pressurized spraying of expanded particles and an adhesive towards a target surface in a manner whereby the adhesive contacts the particles prior to their hitting a target surface. The apparatus involves a spraying device which directs the expanded particles and the adhesive into the intersecting paths necessary to facilitate adhesive-particle contact prior to their hitting the target surface, and serves to minimize loss of the aggregate due to bounce-back of the aggregate from the target surface.
