Technical Notes
The FlexWrap at the sill is the most critical flashing component:
- Sill is where most window leaks occur
- FlexWrap’s flexible membrane conforms to corners
- Creates continuous waterproof pan under window
- Directs any infiltrating water back to exterior
The combination of FlexWrap (sill) and straight flashing tape (jambs/head) is a common and effective approach for window weatherproofing.
