I've got a portion of a roof built with 2x4 rafters. I'm trying to stuff R30 in the space with some airspace-savers underneath, which would normally warrant 2x10's instead. What would be the best way to build these 2x4's out to the depth I need for my insulation? Running
2x10's next to the 2x4's would be annoying, but is the only answer I can come up with. Any suggestions? Any possibility of getting away with 2x6's attached to the face of the 2x4's? Thanks for the advice!- posted
