Putting in two small windows as part of our kitchen remodel (21" x 31").
They are going in an exterior gable wall, framed with 2x6's. I can't get a straight answer from anyone about what "size" header I should put in! Do I have to use 2x10? Or would 2x6 be fine?
Also, any input on how to construct the headers themselves? Should I build hollow and insulate, or actually build solid ones with three 2x's and some sheets of 1/2" plywood to equal 5 1/2"?
Last related question: should I install a double sill plate in this scenario or is a single sill plate sufficient?
I have include two diagrams below. The first shows how I plan to frame out the main openings (implementing a double sill plate). The second diagram shows how I plan to rough in the actual window openings which are represented by the grey areas.
This is how it ended up. Hope it speaks for itself and thanks to everyone for their input.
