The insulation industry’s problem is well documented, if you know where to look. In 1994 by the Insulation Contractors Association of Americas published A Plan to Stop Fluffing and Cheating of Loose-fill Insulation in Attics. The level of candor in this document is surprising. The first sentence of the plan reads, “Whatever one calls it, it is fraud.” The plan goes on to say that “cheating is prevalent throughout the United States” and that “this pattern of fraud has persisted since day one.”
In the photo below you can see how the insulation was never blow right on day one. The cellulose insulation literally tapers down to bear sheet rock. This type of work was routine in the 80’s and 90’s in Arizona.
