I did a search on this topic but couldn't find too much on it. My TF has a ridge beam with 6x10 DF rafters 4' OC and don't want to use SIPS. I do want to use the attic as living space. I plan on putting 2x6 TG down first perpendicular to the rafters. Looking for some different options re: insulation and sheathing.
