1.2 Insulation of piping
1.2.5 Cladding
Cladding in corrosive environments
To guarantee the functionality of industrial/
mechanical insulation (sometimes referred to as
technical 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 also poses a high 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 ® offers
ProRox ® Rocktight, an innovative fiberglass polyester
cladding system.
ProRox ® Rocktight – a durable protection
for insulation
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
(unprocessed) protected against UV rays by foils on
both sides.
ProRox ® Rocktight is soft and flexible when
unprocessed. It can be cut or trimmed in any shape
and easily mounted onto the insulation in this state.
The polyester then hardens when exposed to
ultraviolet (UV) light. Once hardened, ProRox
®
Rocktight is watertight and forms a mechanical
protection for the insulation.
The advantages:
Long service life:
ProRox ® Rocktight creates a sealed, watertight
cladding for ROXUL insulation systems. This
minimizes damage caused by atmospheric
influences or general wear and tear. ProRox
®
Rocktight is resistant to many chemical
substances and forms a mechanical protection for
the insulation.
Easy to clean:
Insulation systems cased in ProRox ® Rocktight can
be cleaned with steam-jet air ejectors, without the
risk of water penetrating the insulation and
causing damage.
Low start-up costs:
The cutting and processing take place directly on
site. This avoids costs associated with
prefabrication of steel cladding.
Flexible applications:
ProRox ® Rocktight can be used for cold and
thermal insulation of underground and
aboveground pipes, for example in offshore plants.
Its high flexibility enables application on complex,
shaped objects.
ProRox ® Rocktight is characterized by easy
processing. It can be cut easily using a knife directly
on site and, as an unhardened ProRox
® Rocktight
wrap (mat) is highly flexible, it can be simply shaped
to cover complex geometric shapes such as pipe
elbows, T-joints or pipe fittings.
ProRox ® Rocktight
has a protective foil on both sides. It is supplied in
rolls in cardboard packaging. The roll is also
wrapped in black foil that is resistant to UV light. The
underside (the side facing the object) is covered with
a dark foil and has a rough, self-adhesive surface.
The flat surface of the outside is covered with a white
foil. After each use, place the roll in the sealed
cardboard packaging to minimize the risk of
hardening caused by daylight or UV light.
