A method of applying dry and substantially thermal and acoustical insulation by spraying an air entrained stream of high velocity pils into cavities, including vertical wall cavities, without having to use any insulation securing means is disclosed. A nozzle system is used that comprises a shredder section for reducing the size of the pieces of insulation to pil size and an accelerator section for increasing the velocity of a stream of air suspended pils for improved just-installed insulation integrity or strength.

The invention claimed is: 1. A method of producing just-installed thermal or acoustical insulation in one or more cavities of a structure comprising inorganic fibrous insulation, the just-installed insulation having a moisture content of less than about 5 weight percent, based on the dry weight of the just-installed insulation, the method comprising; a) feeding clumps, nodules, or mixtures thereof of mineral fiber insulation thereof into a blowing machine whereby the mineral fiber insulation is suspended in an air stream to form an air suspension of the clumps, nodules, or mixtures thereof and blowing said air suspension into and through a hose connected to the blowing machine, an exit of the hose attached to a nozzle system comprising a shredder section and an accelerator section, b) passing the air suspension of clumps, nodules, or mixtures thereof through a shredder of the shredder section located down stream of the hose to produce a moving air suspension containing mineral insulation pils, the majority of the pils having a diameter of less than about 0.15 inch. c) accelerating said suspension containing mineral insulation pils through the accelerator section located downstream of the shredder section to increase the velocity of said air suspension containing mineral insulation pils by at least about 10 percent, compared to the velocity of the air suspension containing the mineral insulation pils before said accelerating, to form a stream and d) directing the stream, into the one or more cavities causing most of the pils to stick to one or more walls of one or more cavities or to each other to form the just-installed thermal or accoustical insulation. 2. The method of claim 1 wherein the pils comprise glass fibers and the pils are accelerated by at least about 50 percent in step c, compared to the velocity of the air suspension containing the mineral insulation pils before said accelerating. 3. The method of claim 1 wherein the pils also contain a functional amount of one or more materials selected from the group consisting of a biocide, a fungicide, IR blocker particles or coating, a filler, a thermal insulating phase change material, an aerogel and a coloring agent. 4. The method of claim 2 wherein the pils also contain a functional amount of one or more materials selected from the group consisting of a biocide, a fungicide, IR blocker particles or coating, a filler, a thermal insulating phase change material, an aerogel and a coloring agent. 5. The method of claim 1 wherein the accelerator section has a tapered portion for increasing the velocity of the air suspension containing said pils coming from the shredder. 6. The method of claim 5 wherein the accelerator section is spaced from the shredder section to permit outside air to enter the stream of air entrained pils before or as it enters the tapered portion of the accelerator section, the latter being joined to the shredder section with one or more structural members. 7. The method of claim 6 wherein the accelerator section is connected to the shredder section with an adjusting mechanism that allows the spaced from distance between the shredder section and the accelerator section to be easily changed. 8. The method of claim 3 wherein the shredder section and the accelerator section are integral or connected together, a portion of a section or portion located upstream of a tapered portion of the accelerator section containing one or more holes to allow outside air to enter the stream of air entrained pils upstream of the tapered portion of the accelerator section. 9. The method of claim 2 wherein the shredder section and the accelerator section are integral or connected together, a portion of the accelerator section or portion located upstream of a tapered portion of the accelerator section containing one or more holes to allow outside air to enter the stream of air entrained pils upstream of the tapered portion of the accelerator section. 10. The method of claim 8 further comprising a movable sleeve capable of covering at least most of the holes for adjusting the amount of outside air that can enter the stream of air entrained pils. 11. The method of claim 9 further comprising a movable sleeve capable of covering at least most of the holes for adjusting the amount of outside air that can enter the stream of air entrained pils. 12. The method of claim 1 wherein the accelerator section is spaced from the shredder section, the shredder section used to convert clumps and nodules to pils, a space formed by the "spaced from" limitation earlier permitting outside air to enter the stream of air entrained pils before, or as it enters a tapered portion of the accelerator section, the latter being joined to the shredder section with one or more structural members. 13. The method of claim 1 wherein the shredder is a motor driven plurality of striking members that impact the clumps and nodules at sufficient speed to break apart many of the clumps and nodules impacted forming pils. 14. The method of claim 13 wherein the acceleration is also accomplished with the motor driven plurality of striking members impacting clumps, nodules and pils. 15. The method of claim 2 wherein the shredder is a motor driven plurality of striking members that impact the clumps and nodules at sufficient speed to break apart many of the clumps and nodules impacted forming pils. 16. The method of claim 15 wherein the acceleration is also accomplished with the motor driven plurality of striking members impacting clumps, nodules and pils. 17. The method of claim 13 wherein the pils produced by the motor driven striking members the pils are accelerated by passing through an accelerating nozzle. 18. The method of claim 14 wherein the pils produced by the motor driven striking members the pils are accelerated by passing through an accelerating nozzle.
