Insulation blowers are greatly useful and their use comes with a number of advantages. Blow-in insulation is a much faster way to make a great improvement on your attic insulation. In a matter of merely an hour or two, an installation specialist can blow a thick blanket of loose insulation across the floor of the attic by using a single hose that is run up through the attic hatch.

For wall cavities, blow-in insulation using an insulation blowing machine is really the only practical way that can be used to improve the R-value of stud cavities, apart from removing entire wall surfaces in order to install faced fiberglass batts.
