The frame and sill profiles on standard performance Wood-Ultrex Sliding French Doors (ISFD) match existing 4-panels. The sill now has the same appearance as the current four panel door. The frame has a continuous back for increased strength and rigidity; there is an exterior accessory kerf.  The sill weather strip is on the same plane as the frame and head jamb profile and the oak sill liner is 5/32" lower and will be shipped loose. The IZ3 and PG50 upgrade has a reduced panel height due to a taller sill and the oak sill liner is taller to align with the sill.
