I am working on a home addition and I plan to change an existing window into a doorway. The window currently has a 2x8 header and a small cripple wall below the header to frame the window.
I need to add a new header to support the load of a new beam that's been installed, so my question is rather than remove the old 2x8 header, can I just place my new LVL header below the existing header? I have plenty of room in both height and width so it's not a problem, I'm just not sure if I can edge stack headers or not.
My guess is it will be ok as long as I toenail the old and new headers together and perhaps place some straps or CDX over the face of both headers to prevent twisting. The house is 20+ years old so I'm not worried about the dimensional lumber of the header shrinking vs. the LVL.
Any comments or suggestions would be appreciated.
