CMS Acoustic Solutions - Total sidewall isolation
Broughton Printers has used CMS ISOSheet to protect a
£14 million investment in a new production facility by
isolating the foundations of a KBA automated reel
logistics system against external vibrations. Supplied
and installed by CMS Vibration Solutions, the material
will prevent external vibration and shock from reducing
the accuracy of the automated reels and stop
machine-induced energy causing structural noise within
the facility offices.
CMS ISOSheet is a medium density closed cell structure
foam. A combination of 50mm and 25mm thick sheets was
used to achieve total sidewall isolation of the
foundation pits, covering an approximate area of 260m2.
To account for greater pressure at the bottom of the
foundations, 50mm thick material was installed from base
level to 2.05m. The remaining depth was covered with
25mm CMS ISOSheet. Once the installation was complete,
concrete was cast in the pit up to floor level.
As part of the expansion plan, and to house the new KBA
Commander presses automated reel logistics system, an
existing warehouse at the Preston site was converted
into a reel preparation zone. When excavating the pits,
main contractor John Turner and Sons, identified that
the foundations were within inches of the water table,
resulting in excess surface water.
While the performance of many isolation materials may
have been compromised, the closed cell structure of CMS
ISOSheet makes it resistant to water penetration. As
well as allowing the foundation isolation to progress
within project timescales, this low porosity guarantees
reliable performance even over time.
Ian Fewtrell, site manager for John Turner and Sons,
said: ³CMS Vibration Solutions were really responsive
and flexible, overcoming the surface water obstacle to
complete the foundation isolation in less than a week
ahead of our own timescales. The installation of CMS
ISOSheet went extremely smoothly and we were really
impressed with the cost and performance of the
material.²
Manufactured using a patented compound, CMS ISOSheet is
designed to isolate the foundations of printing presses
and similar machinery, and offers a cost effective
system where moderate vibration control is required. It
can achieve a natural frequency ranging from 12Hz to
50Hz, depending on the load and material thickness
specified.
Paul Lafone, CMS Vibration Solutions director,
concludes: ³The breadth of our product portfolio enables
us to provide the most appropriate solution for a given
development. In the case of Broughton Printers, the
material hadto be water resistant and at the same time
cost effective criteria which CMS ISOSheet easily
satisfies.²
