Roxul Industrial Insulation Process - Manual (Page 35)

Installation
Before starting the insulation works, ensure that
all preparatory work on the object has been
completed. Refer to Chapter 1.1 for details.
Cut the wraps (mats) to the required length, based
on the external insulation diameter (pipe diameter
+ two times the insulation thickness). Fasten the
wrap (mat) firmly to the pipe with steel bands.
Ensure that the wraps (mats) form a tight joint
and that no lengthwise joints or circular joints are
visible. The joints of the individual wraps (mats)
are securely taped with self-adhesive aluminum
tape. If the insulation is assembled in multiple
layers, the joints of the individual insulation layers
must be staggered.
Support structures and spacers
Spacers are not generally essential in insulation
systems with load bearing wraps (mats). With
pipes that are exposed to large mechanical loads
(e.g. strong vibrations), determine whether a
spacer ring is required in each individual case.
With pipes that have been installed vertically, with
a height in excess of 14 feet (4 m), fit support
structures to transfer the dead load of the
insulation system onto the pipe. Attach the first
support ring to the lowest point of the vertical
pipe. The distance between the support rings
should not exceed approximately 14 feet (4 m).
