High Performance Self-Adhered Flashing with
Non-Asphaltic Butyl-Modied Adhesive
The Better the Seal, the Better the
Performance
The primary purpose of a ashing tape is to prevent the migra-
tion of water and air through window and door openings. Product
performance depends on the adhesive 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 moisture enters and
remains within the wall system, it creates a favorable environ-
ment for the development of rot, mold and mildew. Repairing
these types of problems can be very difcult and extremely
costly.
Air Control is the First Step to Better
Energy Performance
The key to optimizing energy performance is preventing the
movement of air both into and out of the building envelope. Air
leaks around window and door openings make it difcult 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 aggres-
sively 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 exterior of the building envelope.
