Loose-fill cellulose could cause the ceiling to sag if installed at R-38 on V2" ceiling gypsum wallboard with framing spaced 24" on center. Therefore, when deciding whether to use these materials for new construction, consider switching to 5/8" ceiling gypsum wallboard or, if possible, changing your ceiling framing widths to 16" on center.
