Series 526 Impact Installation Instructions
SECTION V: Door Frame Installation
Step 3) Subsill Sealant at Door Frame
Before installing the subsill to the door frame, seal the end of the subsill with a silicone
type sealant. Install the subsill, and tool all excess sealant into the joint where the sub-
sill and door jamb meet. If required, add more sealant to create a smooth watertight seal.
Do not build-up excess sealant as it will keep the sill member of the frame pushed away
from the jamb, if allowed to cure before the sidelite frame is installed. At the glazing
pockets, a build-up of sealant must be used to fill the depth of the pocket up to the level
of the subsill at the glazing area. See figure 2 below for sealant application at the subsill
to door jamb joint.
[Fig. 2]
NOTE: Fill the glazing pocket of the door jamb flush with the sealant to the tallest portion
of the subsill that bridges the pocket. Tool the silicone so a watertight seal is made to
make sure that water will be directed out of the glazing pocket and into the subsill.
Tool sealant across all
seams to ensure a
watertight seal.
Prior to applying sealant to the required areas, clean the area with Isopropyl Alcohol and a clean towel
that will not leave towel materials behind. Wipe off material with a sufficiently dampened towel to remove
all dust, oil, and cutting fluids from the required areas. Allow to air dry before applying any sealant.
