1.3 Insulation of vessels
Selection and installation of the insulation
Preferably use profiled sheets for vessels with a
large surface area. They offer structural
advantages and can accommodate expansions
that are perpendicular to the direction of the
swage. The disadvantage is that pipe protrusions
are more complex from a structural perspective.
Using profiled sheets is only recommended with
cladding with a low number of protrusions.
Design profiled sheet casings so that rainfall is
deflected safely.
Cladding in moist or corrosive
environments
To guarantee the functionality of industrial/
mechanical insulation, it is important to protect it
against atmospheric influences and prevent the
ingress of moisture into the insulation. Moisture in
the insulation system increases thermal
conductivity, thereby reducing the effectiveness of
the thermal protection. It may also increase the
risk of corrosion to the component. In certain
applications, the cladding system is also expected
to offer chemical resistance, as well as being
resistant to cleaning methods such as steam
blasting. Alongside the insulation and
construction, selecting a suitable cladding system
is very important as it forms the basis for a long
service life, low maintenance costs and low heat
loss of a industrial/mechanical insulation.
ROXUL Inc. has developed an innovative cladding
system for industrial/mechanical insulation:

Rocktight – for durable
protection
ProRox
®
Rocktight is a fiberglass reinforced
polyester wrap, which hardens when exposed to
ultraviolet (UV) light. The material contains resins,
glass fibers and a special filling agent and is
protected against UV rays by foils on both sides.
ProRox
®
Rocktight is soft and flexible when
unprocessed. The polyester then hardens when
exposed to ultraviolet (UV) light. Once hardened,
ProRox

Rocktight is waterproof and forms a
mechanical protection for the insulation.
