Core Sampling Cellulose Insulation Density

It is often useful to be able to determine the installed density of dense-pack cellulose in a wall. Because the installer must work without the benefit of viewing the coverage or density, core sampling was devised many years ago to measure these important metrics. If the density is too low, the R-value and air leakage degrade. If the density is too high, insulation and labor are wasted.
