Can blown-in fiberglass/cellulose be too dense?
I’ve been through a couple of homes where the fiberglass within the wall cavities was extremely dense. Is there such a thing as too dense with blown-in fiberglass? If so, how do you measure the appropriate density in the field.
I know the R-value of fiberglass batts decrease if compacted in a cavity due to the lack of air between the fibers, and I’m wondering if the same principle applies to blown-in fiberglass and cellulose insulation?
