Flexible ArmaTuff Plus, ArmaTuff
White or ArmaTuff Silver can be
used for all exterior applications.
They are practical also for use on
exterior ducts, tanks, vessels,
large pipes and fittings. The
material provides a durable,
tough and maintenance-free sur-
face. The material is resistant to
UV, ozone, acid rain and most
industrial pollutants. No painting
is required.
The recommended temperature
usage range for ArmaTuff is
-70°F to 180°F (-57°C to 82°C).
The closed cell structure of
ArmaTuff insulation effectively
retards the flow of water vapor,
and it is considered a low trans-
mittance vapor retarder. ArmaTuff
does not require additional vapor
retarder. The white surface
reflects heat to reduce energy
load.
ArmaTuff is installed using
Armaflex 520 or 520 BLV adhe-
sive or with pre-applied pressure
sensitive adhesive (PSA). For
application to large, flat or curved
metal surfaces such as ducts,
vessels, very large pipes or tanks,
full Armaflex 520 or 520 BLV
adhesive coverage or product
with PSA is used. The seams
must be installed in compression
and sealed with Armaflex 520 or
520 BLV Adhesive. Cover the
seam with 4″ and exposed edges
with 4″ or 6″ ArmaTuff Seal Tape.
Armaflex 520 or 520 BLV adhe-
sive is a contact adhesive: there-
fore it must be applied to both
surfaces, allowed to get tacky,
and the surfaces are joined with
pressure.
Please note: For installing self
adhering SA Armaflex sheets and
rolls, refer to p.19.
ArmaTuff is designed for installation in above ground applications.
Armaflex insulation products must be installed according to
Installation of Armaflex Insulations brochure. Proper installation is
required to assure Armaflex insulation performance.
Applying Non-Self Adhering ArmaTuff Sheets
1. Always prepare surface by
cleaning with denatured
alcohol.
2. Insulate sides first. Apply
thin, uniform coat of
Armaflex 520 or 520 BLV
Adhesive.
3. Roll thin coat of 520
or
520 BLV
Adhesive to
insulation.
4. Position carefully and apply
ArmaTuff. Contact
adhesive bonds instantly.
5. Apply ArmaTuff to top sur-
face, overlapping the side
pieces.
