SECTION VI: Subsill Fabrication and Installation
Step 3) Subsill Weep Fabrication
Step 4) Subsill Weep Baffle Installation
Step 5) Subsill Installation When End Dams Are Not Required
Drill 3/8” weep holes in subsill 6” from each jamb/vertical and no more than 42” apart.
[Fig. 8]
An end dam may not be required in all cases. Before installing a subsill without an end
dam, determine if the surrounding condition can be used to create a water dam, and if the
material will not degrade over time if it comes into contact with water. Once it has been
determined that the condition is appropriate to create a water dam, continue the installa-
tion of the subsill as described in Steps 6-10 of this section.
Weep baffles (FWE5) are placed on the subsill behind the weep holes. Apply a small
amount of silicone type sealant to the baffles, and locate them over the weep holes as
shown in figure 9. Ensure the sealant does not cover the weep holes.
Apply sealant on bottom of
baffle before installation.
