I am installing a bifold door into an existing opening. I just refinished the opening and it is now drywall wrapped and painted. Had I been thinking about it, I would have made sure the opening was the right size, but the plan at the time did not involve a bifold so I didn't bother.
The finished opening is 31 & 1/2 inches (give or take 1/16 or so).
I bought some used doors at the Re-Store and they are exactly 16 inches each.
I had planned on trimming the two outside edges to fit.
My question is: should the trimmed door be the exact size of the opening (31 1/2), meaning i would trim 1/4 inch off each side, or should there be some allowance on each side (if so, how much)? also do I need to allow any space for the hinge, as that would add a 16th or 8th or an inch, unless, as I just realised the hinge is mounted on the back as opposed to between the doors. Which method is recommended?
Lastly, I know I can trim the bottom of the door, how much allowance should I leave at the top and bottom of the door. I don't remember the exact measurment of the opening, but I figure there's probably a X number of inches shorter sort of rule.
I'd appreciate any help on this one.
