All portions of the frame and surrounding conditions where sealant will be
applied should be cleaned and prepped per the sealant manufacturer's
recommendations. Use 795 or equivalent silicone type sealant to create
the perimeter seal of the system at both exterior and interior perimeters.
Exterior and interior seals are required for air and water performance.
Begin by pushing caulk backer rod into position around the full perimeter of
the frame at the head and jambs. Push the backer rod into the gap
between the frame and condition so it sets below the frame edge. See
figures 47 and 48 below for backer rod placement. The 795 sealant should
be applied by a skilled tradesman to ensure proper seal and appearance.
See figures 49 and 50 below for sealant application.
