I am starting to open the wall between my kitchen and my living room. This is a top floor with nothing above the wall in the attic except for 2x6 ceiling rafters running the 25' wide of the two rooms (two lengths of rafters that are nailed together directly above the wall I want to remove). The wall I want to open will be 22' in length between the two rooms.
I can either put a beam up in the attic and attach the rafters to that beam or I can have a beam below the ceiling but I would not want to go more than a 12'' below the ceiling.
Can someone tell me what size of beam I would need to use in this project? Thank you Duane
