with liquid applied
ashing as shown.
3. If installing into a
four-sided buck, seal
the sill in a similar
manner.
Note! Shims must be 1/4" shorter than the depth of the window sill,
should level the rough opening sill and be no more than 1/4" thick.
4. Shim the sill 4" from each corner, at 8" intervals, and on both sides of
mull joints with non water-degradable or compressible shims. Secure
shims with sealant.

manufacturers’
instructions for
trimming).
PREPARE SILL
1. Measure the width
of the window's sill
+ 1/8" and transfer
the measurement
onto the rough
opening sill. This is
where the back of
the JELD-WEN drain
mat will sit.
2. Cut a piece of drain
mat the length of
the sill plus 6".
3. Without cutting the
drain mat material,
remove 3" of the foam wedge from each end of the JELD-WEN drain
mat.
4. Place drain mat on
rough opening sill,
wrapping the drain
mat up 3" on each
jamb as shown.
5. Lift up the back of
the wicking and
staple into place on
the sill.
6. Pull release tape
and set JELD-WEN
drain mat into
place.
7. Fold the drain mat
down onto the
sheathing. Staple
drain mat to the
wall and seal the
corner edges as
shown.
8. Smooth out any
bubbles or creases
with a J-roller.
