ABSTRACT:
A manually operated insulation gun for injecting particulated insulation into a confined wall space is disclosed. The insulation gun includes a tubular housing for receiving a load of particulated insulation material and a piston slidably disposed within the housing for ejecting the insulation material. The piston is manually operated by means of a piston rod attached to the piston and which projects through a closed end of the housing. A plunger is coupled to the piston and the closed end of the housing for breaking up compacted accumulations of the insulation material. A fill nozzle is connected to the discharge opening of the tubular housing for directing the flow of insulation material into the wall space. The fill nozzle is preferably slightly tapered which causes the insulation particles to travel in swirling, turbulent movement as they are discharged into the wall space, thereby promoting the uniform distribution of insulation within the wall space and also promoting expansion of compacted nodules of material to minimize the insulation density.
