Can Fiberglass Work if Done Properly?
I know that most of the folks in this forum dislike the use of fiberglass because it does not maintain its R-value in leaky wall cavities due to air washing. My question is: if a wall cavity was completely sealed - as in the sheathing was caulked or glued to the framing and the sheetrock was glued to the framing during installation - would fiberglass work ok? If so, does it make sense to dense pack? I know that R-19 (5.5 inch) does not keep it's full R-value if compressed into a 3.5 inch space, but does it do better than standard R-13 (3.5 inch)?
