For example a four-foot wide (48”) by six feet, eight inches high (80”) Bifold
set of doors, would require a rough opening width of 50 inches and a height of
This sized rough
opening will allow for either a doorjamb kit to be installed or for ¾” thick
select lumber to be used to create the finished doorjamb.
Note that most
bifold door assemblies do not come with a doorjamb kit so using ¾” thick select
lumber to create the finished doorjamb is fairly common. The bifold door
mechanical bracket assemblies actually screw into this finished doorjamb so it
is important that the doorjamb be installed plumb and level.
To complete the
interior trim work associated with the doorjamb, when using ¾” select lumber,
case moulding is wrapped around the perimeter of it. For best results, mitered
cuts are employed.
Sizing a Bifold Door Rough Opening for a
Sheetrocked Wrapped Opening
If the Bifold door
is to be installed into a sheetrocked wrapped opening the rough opening width
should be sized to the actual width of the Bifold doors (48” in the case of this
example). The rough opening height should be the height of the door plus 3/4"
(80 ¾” in the case of this example).
that these guidelines are typical framing standards that are employed in the
home construction business. You should always check with the manufacturer or
product specifications to confirm the rough opening requirements for your
particular bifold doors.
