(building a 30 foot deep garage...)
Okay, attaching a spf roof joist and spf ceiling joist is pretty straight foward with birds mouth cuts and being nailed into the spf ceiling joist, but since I plan on spaning 30 feet, engeneered floor/ceiling joist seem to be a better plan, but how is the spf roof joist attahced to the engeneered ceiling joist?!
fill the center of the engeneered joist with ply for nailing?
