window waterproofing and install help

Karen
last month

My Kolbe Forgent windows are being installed on Monday by an installer Kolbe distributor chose.

The sales guy originally told me they were using a waterproofing material called Vellum or something. Today I was told they were going to use Sherwin Williams Conflex.

Is this a good product? Is there anything I need to ask them or make sure they do? Installation is concrete block house in Florida. Windows are impact, casement, Kolbe Forgent Glastra material.

Feeling unprepared. DH us our GC.
