A system and corresponding method are disclosed for blowing or spraying loose-fill insulation (e.g. fiberglass) into wall cavities and the like the system including a fiber recovery or recycling subsystem that vacuums up overspray or waste fibers and forwards them back toward the hopper. A fiber collector device having a fiber inlet and outlet is mounted above the hopper, and receives the recovered waste fibers and redistributes them back into the hopper so that they mix with virgin fibers therein. The mix of recovered and virgin fibers is then blown through the blow hose toward a wall cavity or the like to be insulated.

[ I claim:] [5.] A method of blowing a loose-fill insulation and dry adhesive mixture together with an adhesive activating liquid into a vertically extending open wall cavity, the method comprising the steps of:feeding a virgin mixture of loose-fill insulation and dry adhesive into a hopper, and forwarding the virgin mixture from the hopper to a blow hose;blowing the virgin mixture of loose-fill insulation and dry adhesive from the blow hose together with the adhesive activating liquid into the vertically extending open wall cavity so that a first portion of the blown mixture is retained in the cavity and a second portion of the blown mixture falls to a floor located beneath or proximate the cavity;vacuuming up the second portion of the mixture from the floor and forwarding the vacuumed up second portion back toward the hopper through a return hose;receiving the vacuumed up second portion from the return hose in a cavity defined within a collector housing that is mounted at an elevation vertically above the hopper, said collector housing having an inlet and an outlet defined therein;allowing the received second portion to fall from the cavity, through the outlet, and into the hopper and intermix with virgin mixture within the hopper; andblowing virgin mixture, together with the recycled second portion that has fallen from the cavity into the hopper, through the blow hose and into an open wall cavity to be insulated.
