Building Paper Applications
Figure 16: Rough opening preparation for construction methods using building paper and rigid sill panning.
1. Cut a 9″ (229) wide strip of Grade D building paper
approximately 24″
(610) longer than the window
rough opening width. Center the strip even with the
bottom of the RO and staple along the top edge only.
See figure 16a.
2. Run a bead of sealant approximately 3/4″
(19) from
the edge of the opening. Start the bead about 6″
(152)
up from the sill (or the height of the sill panning). See
figure 16b.
3. Install rigid sill panning following manufacturer’s in-
structions. See figure 16c.

4. Cut a 13″
(330) piece of Grade D building paper
24″
(610) longer than the RO height (adjust width for
jamb depth).Tack the piecesin place, overlappingthe
RO by as much as the jamb depth. Use a utility knife
to cut the paper even at the head jamb and sill. Fold
jamb flaps to the interior and tack in place. See figure
16d.
5. Apply a continuous bead of sealant 3/4″
(19) from the
top and sides of window opening. Do not apply seal-
ant to RO bottom. Seal any fasteners used to attach
panning to the sill. See figure 16e.
