Flashing Systems

Specifier Note: The purpose of this guide specification is to assist the specifier in correctly specifying flexible

flashing products and execution. The specifier needs to edit the guide specifications to fit the needs of specific

projects. Contact a DuPont

Tyvek

Specialist to assist in appropriate product selections. Throughout the

guide specification, there are Specifier Notes to assist in the editing of the file.

References have been made within the text of the specification to CSI MasterFormat 2004 Section numbers

and titles. The specifier needs to coordinate these numbers and titles with sections included for the specific

project. Brackets [ ]; “AND/OR”; and “OR” have been used to indicate when a selection is required.

This guide is for commercial flashing applications in conjunction with weather barrier assemblies. These high-

performance flashing membranes are designed to help stop the passage of bulk water and airflow movement

and are vapor non- permeable. These commercial flashings offer protection for the building envelope by

providing a water-resistant barrier around penetrations and rough openings.

These commercial flashings are specifically designed for above grade, vertical wall surface openings or

penetrations where the wall assembly may consist of any of the following: exterior-grade or glass-faced

gypsum sheathing, exterior plywood sheathing, oriented strand board (OSB) sheathing, stud walls with no

sheathing, and masonry wall construction.
