Landings
These instructions cover two patio door sill conditions: the step-down
landing and the continuous slab landing. The installation methods vary
slightly between landing types.
Prepare Sill
1. A pan ashing system
(as dened in ASTM
E-2112) is required
at the sill prior to
window/door product
installation. Always
allow water to drain
out of the pan and
onto the building wrap,
drainage plane or to
the exterior.
NOTE: Sill pans for step-
down landings will have a folded-down edge in the front to accept the
step-down landing.
Continuous Slab LandingStep-Down Landing
2. Apply a continuous
bead of sealant to the
interior of the upturned
leg and end dams of
the sill pan (if using a
rigid sillpan).
Shim the Sill
See Product Installation Tolerance Table for tolerances.
Unless installing into a
sill pan with a positive
sloped draining system,
shims should be aligned
as dened by the label
on the patio door or as
statedbelow:
• Shims (1/4" maximum)
should be placed near
the exterior edge of the
sill pan.
• Place one shim 2" from each side of the rough opening (if the rough
opening is sized correctly, this should be approximately 1 1/2"- 2" from
the corner of the patio door).
• Shims should be no more than 8" on-center.
• There should always be a drainage path to the exterior out of the sill pan.
• Shims can be held in place with sealant.
• Increased shim height may be needed or may interfere with bar/grill
alignment of adjacent windows/doors.
