How to Frame Window and Door Openings
Framing Windows and Framing Doors
Overview:
Framing exterior
walls for windows and doors is one of the easier
tasks in homebuilding. Although it is a relatively
easy task, there is still a sequence of steps that
should be followed to insure your door openings and
window openings are constructed to the correct
rough openings. There really is more to framing a
wall than just nailing some studs to the plate and
standing it up.
Position the top plate back on the floor so it is
approximately eight feet from the bottom plate.
This gives you room to lay out the stud material to
frame the wall. If there are windows or doors in
the wall lay out the headers, sills and, jacks in
their corresponding locations.
Window and door openings should be framed first to
facilitate the work.
The reason why it is best to frame these
details first is when framing window and door
openings nails are driven through the sides of
studs into headers, jacks, and sills. If the wall
studs are nailed in before the openings are framed
there would not be enough room to swing a hammer or
use a nail gun. Even if the openings fall 16 inch
on center it still would be a little difficult to
swing a hammer.
Framing a window opening:
1.
The order of nailing a window opening together is
also important. Using a standard eight foot wall as
an example, all the headers are 2x12. The first
step is to nail the header to the top plate. The
header is cut to the width of the window plus three
inches to allow for the 2x4 cripples.
2.
The next step is to nail the studs to both ends of
the header and to the top plate using 16 penny
nails.
3.
Nail the jacks in place. These determine the height
of the window. The cripples butt up to the bottom
of the header and are nailed to the inside of the
studs. The 16 penny nails must be put in at an
angle to keep them from coming through the stud
causing injury.
4.
The next step is to nail the sill to the bottoms of
the cripples. The window framing is completed by
adding jack studs beneath the sill.
Framing a door opening:
1.
To frame a door opening use the same procedure
except there is no sill. Studs are nailed to each
end of the header and then a measurement is taken
from the bottom of the header to the bottom plate.
This will be the length of your cripples.
2.
The jacks are nailed in just like the window jacks.
The bottom plate is cut out later on in the
construction stage before the door is set in
placed.
3.
Once all the window and door openings are framed,
nail in the wall studs to complete the wall. Follow
the layout and nail everything on the right side of
the line which will be indicated by an "X", this
will give you a 16 inch on center spacing.
Now you know how to frame window and door openings
and have the wall completely studded, it’s time to
stand up the wall and nail it in place on the floor
deck. Note: Jacks are often referred to as
cripples, however, the term “cripples” is more
often used in defining elements of hip roof
construction.
