1.2 Insulation of piping
Insulation of piping
Consequently the number of thermal bridges,
which have a negative influence on the insulation,
is greatly reduced.
The result is considerably reduced installation
time and costs. The lack of spacers and
“unforeseen” gaps minimizes heat losses and the
risk of personal injuries due to hot spots on the
cladding.
Pipe wraps (mats) are tailored to the
corresponding length of the pipe circumference
on site and are fastened with clamps.
Insulation with wired mats
Wired mats, are lightly bonded stone wool wraps
(mats), usually stitched with galvanized wire onto
a galvanized wire mesh. For more details on
ProRox
® wired mat insulation products, contact
your ROXUL ® representative.
Pipe insulation with wired mats has been a
time-tested universal solution for many decades
now. Due to their flexibility and high temperature
resistance, wired mats can be easily cut and
mounted onto piping. Wired mats are ideal for
application in situations where the use of pipe
sections or load bearing wraps (mats) is difficult
or impossible. Historically this included large
diameter pipes and high temperatures (where the
wired mat provided structural integrity to the
insulation at high temperatures), but advanced
modern ProRox
® pipe section and ProRox ® pipe
wraps (mats) have provided a suitable alternative
to wired mats. Wired mat is still used today in
piping with a high number of shaped pieces such
as elbows or T-joints.
Wired mats have a relatively low resistance to
pressure and from a practical point of view should
only be mounted in combination with spacers or
support structures. Because of the resulting
thermal bridges, better insulation performances
are often achieved in the lower and middle
temperature range [up to 550 °F (300 °C)] with
pipe sections or load bearing wraps (mats).
