1. How to frame a Window Rough Opening:
The very first thing you must do is purchase the desired, pre-hung
window to learn what the dimensions of the prescribed rough opening.
Determine the location and dimensions
of the new wall and the position of the window. You have built
the first wall, Wall #1, per the instructions for "How
to Build a Wall." The three 2x4's end the Wall #1 where
the corner will meet Wall #2 with the window opening.
2. To build the second wall, measure from
the base plate of Wall #1 to where Wall #2 will end. With this
measurement, cut the two top plates, and the bottom plate to size.
Install the Top Plate #1 of Wall #2 and mark the placement line for
the Base Plate of Wall #2 per the instructions found in: "How
to Build a Wall."
3. Select Top Plate #2 of Wall #2 and the
Base plate and layout and mark the placement of the studs every 16",
per the wall building instructions. Given the rough opening
dimensions provided by the window manufacturer, decide the placement
of the window opening; mark the rough opening space on the Base Plate
and Top Plate #2. As shown above, measure and mark out from
each edge of the rough opening, 1 1/2" for the "Jack Stud" placement,
and 1 1/2" for the "King Stud" placement.
4. Cut the studs and nail them in place per
the wall building instructions including the "King Studs" (do
not nail the "Jack Studs at this time).
5. Select the two Jack Studs, measure, mark,
cut the Jack Studs to the dimensions of the lower portion of the vertical rough opening;
subtract 1 1/2" to allow for the thickness of the Base Plate; nail
the lower Jack Studs in place.
6. Select a 2 x 4, measure the distance
between the King Studs; Measure, cut, and nail the bottom, cross-plate,
as shown above.
7. Select the two remaining portions of the Jack Studs, measure, mark,
cut the middle Jack Studs to the dimensions of the vertical rough opening;
the middle Jack Studs in place.
8. Select a 2 x 4, again, measure the distance
between the King Studs; measure, cut, and nail the top, cross-plate,
as shown above.
9. Select another piece of 2x4, measure the
distance below and above the window opening; measure, cut, and nail the Cripple
Studs as shown above. Place the Cripple Studs in place to
maintain the consistent 16" stud placement.
10. Lift Wall #2 into place; ensure the
boards making the corner are tight and lined up with the existing
wall #1. If Wall #1 is plumb, the Wall #2 should also be plumb
from top to bottom; the corner should be straight and plumb.
Nail the Top Plate into place and then secure the base and the
corners at each end of Wall #2.
11. With the wall in place, drill the
necessary holes for wire or pipes; add the wire and pipes; be sure
to nail any necessary metal pipe guard plates onto the studs.
12. Add the stud covering material of choice
and have a fun day. Access the following tips:
