5XPT SLIDING GLASS DOOR INSTALLATION INSTRUCTIONS
See Fig. 10 for Step E below:
Step E. Marry a vertical seal to the already applied sealant across the sill; seal the joint between the
fixed panel meeting rail and the threshold. This seal joint will follow the underneath profile of
the threshold and fill the gap between both the horizontal and vertical weather-strip. Seal over
thermal break at least 2” up from the sill as shown. This seal will never be seen once the
operable panel is loaded. All sealant joints must be continuous with one another and
tooled with no voids.
Note:
The sealant at the head is an exact mirror of the sealant applied to the sill as
shown in Figs 8, 9, and 10.
All sealant must be continuous with
one another and tooled with no
voids.
