Framing additional 12’ garage doorReport
Please briefly explain why you feel this question should be reported.
Hello! I have a basic detached 2 car garage with a 16’ OH door that was built in 2004. I am looking to frame and install another 16’ or perhaps a smaller 12’ bifold door on backside of garage so that it opens to backyard patio. In terms of framing, can I essentially mirror the header and cripples on the side that is finished to frame this additional opening? Or would further support be required so that sagging does not happen or so there is no structural weakening?
