Ceiling strapping spacing recommendation to hold up 22" of blown-in cellulose
I am in the process of trying to determine how much strapping spacing is needed on a ceiling to support 22" of blown-in cellulose above it. The strapping is 1x4 pine and I plan on spacing 16" OC whixh makes the space between supports of 12". The strapping is holding 6 mil poly up against the bottom chord of the truss. There will be some ballooning of poly downward in those squares between truss and strapping. 5/8" Sheetrock will be used up against strapping to finish. Thanks in advance.
