High Performance Self-Adhered Flashing with
Non-Asphaltic Butyl-Modified Adhesive
The Better the Seal, the Better the
Performance
The primary purpose of a ashing tape is to prevent the
migration of water and air through window and door
openings. Product performance depends on the adhe-
sive bond between the ashing and the substrate. This
is especially true for irregularly surfaced materials such
as OSB. The better the adhesive seals itself into the
peaks and valleys of the substrate, the better the barrier
against water and air migration.
Moisture Control is the First Step to
Mold Control
Water from both exterior and interior sources is among
the worst enemies of building structures. When mois-
ture enters and remains within the wall system, it
creates a favorable environment for the development of
rot, mold and mildew. Repairing these types of prob-
lems can be very difcult and extremely costly.
Air Control is the First Step to Better
Energy Performance
The key to optimizing energy performance is prevent-
ing the movement of air both into and out of the
building envelope. Air leaks around window and
door openings make it difcult to keep a comfortable
indoor environment, forcing the HVAC system to work
harder, while driving up energy costs.
A properly integrated ashing tape that adheres and
seals aggressively to the substrate will create the most
effective barrier against water and air migration while
acting as a drainage plane to shed water down the exte-
rior of the building envelope.
