5. If fasteners are
required through
the sill, cut a piece of
self-adhesive ashing
the length of the sill
and apply over the
entire sill pan. For
step down landings,
fold ashing down
as shown. For
continuous slabs,
trim ush with rough
opening.
6. Cut two pieces of
self-adhesive ashing
6" wide by the sill
pan width + 3" long.
a. For continuous
slab landings
only, cut out the
inside corner.
b. Adhere the
pieces of
ashing to the
inside corners.
Stretch ashing
as needed to
cover corners
and lay at.
7. Smooth gaps or
bubbles beneath
self-adhesive ashing
with a J-roller
(remove and replace
if necessary).
8. Seal back corners of
sill pan with sealant.
9. For step-down
landings only, allow
for the drainage and
drying of incidental
moisture out of the
rough opening. Do
not apply sealant to
the face of the sill
and/or trim pieces so
that they block water
drainage.
End of Stud-Framed
Wall Instructions,
continue with section
6, “INSTALL DOOR.”
PREPARE BUILDING WRAP
Verify these steps are
allowed by the building
wrap manufacturer.
Note! Steps 1 and 2
apply only to new
construction.
1. Trim building wrap
ush with the
edges of the rough
opening.
2. If the door extends
beyond the exterior
plain of the building
and a drip cap is
desired, at the head, slit building wrap 6" at 45°. Tape up as shown.
We recommend installing a drip cap because this integrates the
building wrap and drip cap to protect the structure and the product
from incidental water.
Note! The rest of the steps in this section only apply to a job site
fabricated sill pan. If installing a sill pan that you have purchased,
follow manufacturer's instructions for installation and skip to section 6,
“INSTALL DOOR.”
3. If installing a metal sill pan on concrete, cut a piece of self-adhesive
ashing the length of the sill pan and adhere it to the entire bottom
surface where the pan will sit on the concrete.
4. Apply spray adhesive/primer to the sill pan and surrounding area.
Follow manufacturer’s instructions for application methods.
