Extendable Self-Adhered Flashing For Sealing Around Non-Flanged Objects
DuPont

FlexWrap
™
EZ is a flexible, self-adhered tape
with a 100% butyl-based adhesive layer that creates
an air and water-tight seal around penetrations of all
different shapes and sizes. FlexWrap
™
EZ is available in
a 2 3/4 in x 15-ft roll roll length to provide an option for
home builders, trade contractors and remodelers to
easily seal around non-flanged objects that penetrate
the building envelope. It is ideal for flashing around
many smaller wall protrusions like plumbing and HVAC
components, vents, wires, exterior electrical outlets,
exterior lights, and gas lines. FlexWrap
™
EZ is a part of a
complete line of DuPont Building Envelope Solutions that
help to improve the energy efficiency and durability of
buildings.
This bulletin provides
installation guidance
when the wall penetration
rough opening (RO) is not
more than 1/2" larger than
the outside diameter/
dimension (OD) of the
non-flanged product.

General Considerations
For best results, install DuPont
™
Tyvek
™
Water-Resistive
and Air Barriers (WRB), or other weather-resistive
barrier before installation of a product that penetrates
the exterior sheathing. Once in place and secured,
the penetrating object can be sealed directly to the
weather-resistive barrier using FlexWrap
™
EZ to establish
continuity of the drainage plane.
Please refer to the applicable DuPont Weatherization
Systems Installation Guidelines for more information.
Maintain careful placement of the exposed butyl during
installation once the release paper is removed. DuPont
recommends installers evaluate suitability of FlexWrap
™
EZ onto non DuPont
™
Tyvek
®
WRBs.
Sealing Round Pipes, and Other Round Objects, with Outside Diameters (OD) Less Than 2"
1. Cut a piece of FlexWrap
™
EZ
that is 1/2 the length of the
pipe circumference.
2. Fold the FlexWrap
™
EZ to
break perforations in release
paper and create sharpe
crease.
3. Remove narrow (~1")
width of release paper.
4. While still folded, center
FlexWrap
™
EZ under the
pipe and use the remaining
release paper edge to
position FlexWrap
™
EZ tight
against the WRB. Adhere
the exposed butyl to the
underside of the pipe.
5. Gently remove remaining
release paper to avoid
stretching the product.
