2. The foam wedges 
included with French 
and Patio doors are 
used to complete the 
weatherstrip seal at 
each bottom corner 
of the operating door 
panel(s). Doors will 
be provided with 
one of two types of 
wedges. One has an 
upturned L-shaped leg 
(shown) and the other 
is a simple wedge. 
For both types, gently 
pull the weatherstrip 
ap away from the frame and position the wedge behind the 
weatherstrip and against the sill so that the thin edge faces the edge 
of the door as it swings closed. Remove the backing paper and stick 
the wedge to the frame. Apply a bead of sealant at the intersection 
of the jambs, brickmoulds, thresholds and oor as shown.
3. Apply sealant at the 
bottom where the 
sill meets the frame 
on both sides. If a 
sill extender is used, 
apply a bead of 
sealant between the 
sill and the extender. 
Apply sealant around 
any mulls at the 
intersection of the 
mull and door sill.
4. Apply sealant around 
the outside of the 
door unit between the 
siding and brickmould and between the brickmould and the jamb. 
Also apply sealant between the jamb sides and the threshold. Run a 
bead of sealant, leaving 1" gaps every 2', along the front side of the 
threshold where it meets the slab/rough opening.
5. Create a continuous air seal on the interior between the rough 
opening and the frame with low expansion foam.
