SLIDING GLASS DOOR INSTALLATION INSTRUCTIONS
Apply a continuous silicone seal at the fixed
panel to door frame along the parting stop at the
head, jamb, and sill. The silicone seal must
continue behind the meeting rail interlock to seal
the meeting rail to the head and sill forming a
continuous seal.

Marry the continuous silicone

Meeting Rail
Important: The seal joint shown is the
weathering seal that prevents air and
water from entering around the fixed panel.
Note: To properly seal the fixed panel, the seal behind the meeting rail interlock must be
done before the operable panel is loaded into the frame. If the fixed panel seal is to be
applied at a later time, a partial seal behind the interlock pocket must be made before
loading the operable panel. This partial seal should be the width of the meeting rail sightline.
The sealant applicator can then marry the perimeter fixed panel sealant with the sealant
already applied in the interlock pocket after loading the operable panel.
