TRANSCRIPT
If you are designing a building to last over 20 years,
the right air and moisture system is critical.
DELTA®-VENT SA Air barrier & water-resistive barrier.Aggressively self-adhering. Highly vapor permeable.
DELTA® protects property. Saves energy. Creates comfort.
Air and Moisture Barriers – Problems and Solutions
Problem
Sometimes membranes must be left
exposed for a period of time before being
covered by the exterior cladding. Exposed
membranes are susceptible to the
damaging effects of ultraviolet rays.
Solution
DELTA®-VENT SA resists the harmful effects
of ultraviolet better than any other mem-
brane. Some manufacturers may claim that
their membrane can be left exposed for up
to 6 months. As these graphs show, you
will see the reduction in performance as
the membranes from other manufacturers
are exposed.
UV Protection
■ 2
What is the planned life of your exterior cladding? Will the membrane behind the cladding last as long?
Solution
As this chart shows, DELTA®-VENT SA exceeds
the adhesion requirements. Be sure check
the test results of any membrane you specify.
Solution
DELTA®-VENT SA invests in and passes the
required tests and reports the results. Ask to
see the test results for any membrane you
specify and be sure to check the test date to
make sure it is still valid.
Problem
The minimum standard for adhesion to a
surface without primer is 26 N/mm. Some
membrane manufacturers promote the
adhesion of their products while not meet-
ing this minimum standard.
Problem
To insure membranes perform as required
it is important they are tested by a recog-
nized testing facility and that these tests
are current. Some tests require retesting
every year.
Some manufacturers either don’t pass or
don’t invest in the tests as they do not
report the results for their membranes or
they use outdated test results.

Problem
Some suppliers buy product from a
manufacturer in a different country and
put their name on it just like many house-
wrap suppliers. When you are not the
actual manufacturer it is hard to control
quality.
Solution
DELTA®-VENT SA and most other leading
brands of membranes are manufactured by
the company who sells them. This means
the technical and engineering people are
directly involved in quality control and con-
tinuing product improvements.

Air and Moisture Barriers – Problems and Solutions
Problem
The National Air Barrier Association (NABA)
and Air Barrier Association of America
(ABAA) evaluate and test membranes.
Some membrane suppliers are not recog-
nized and approved by either association.
Solution
Both associations approve
DELTA®-VENT SA and is the
only membrane approved
by the Air Barrier Association
of America (ABAA). Make
sure any membrane you
specify is at least recognized
by The National Air Barrier
Association (NABA).
Problems with the design, membrane selection and installation are one of the most costly problems in commercial construction today. Make sure you are designing the right systems with the right products for each building.
Problem
One of the benefits of fully adhered mem-
branes is that they eliminate the penetra-
tions that happen with mechanically fas-
tened systems. That leaves the seams or
edges as the remaining potential source of
problems..
Solution
DELTA®-VENT SA is the only membrane with
a self-adhering edge that eliminates the
problems with seams and edges not being
sealed properly. If you use any other mem-
brane be sure that the installer takes the time
to properly seal the edges.
Problem
An air and moisture membrane has to work
with other components such as flashing in
order to properly protect the structure.
Some membrane suppliers do not offer the
other components. Without a systems
approach you are at risk of combining com-
ponents that may not work well together.
Solution
DELTA®-VENT SA and most other leading
brands of membranes offer all the compon-
ents required for a successful installation.
Make sure the membrane you specify offers
a total systems solution.
Problem
The design, specification and installation
of membrane systems can be very compli-
cated and require technical expertise.
Some suppliers do not offer the high level
of technical support required to make sure
each building has the right solution.
Solution
DELTA®-VENT SA and most other leading
brands of membranes offer the technical
support required for architects to design the
right solution. DELTA® offers extensive tech-
nical manuals and installation videos as well
as the availability of consulting with one of
our engineers.
