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 w indow

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 pieces in place, overlapping the

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.
