Claim:
A method for installing insulation into cavities formed into a wall of a building, each of said wall cavities being defined by an exterior wall, vertical studs having an outward surface, a horizontal top plate, and a horizontal bottom plate, said method comprising the following steps; (a) hanging a sheet of minimal stretch reinforced polymeric plastic material against said studs and attaching said sheet to said top plate and said bottom plate; (b) cutting a plurality of tracks to fit onto and around said outward surface of said studs between said top plate and said bottom plate, and mounting one of said tracks onto and around said outward surface of each of said studs; (c) drilling holes into said tracks at generally regular intervals and inserting screws into said holes and through said sheet of polymeric plastic material using a screw gun to pull said sheet of polymeric plastic material tight, (d) cutting an opening into said sheet of polymeric plastic material and inserting an insulation tube therethrough, and blowing dense pack insulation through said tube into said wall cavity until said cavity is completely filled, then withdrawing said tube and sealing said opening; (e) removing said tracks so that said tracks can be re-used; wherein when re-using said tracks, said tracks have already been cut as in step (b) and drilled as in step (c); therefore in the second and subsequent uses of a track, step (b) is modified to be: mounting a track onto and around said outward surface of each of said studs; and step (c) is modified to be: inserting screws into holes in said tracks and through said sheet of polymeric plastic material using a screw gun to pull said sheet of polymeric plastic material tight; steps (a), (d), and (e) remaining the same as recited above.
