SoundBreaker
Bars
Description
SoundBreaker Bars are lengths of hot dip zinc steel, formed into
a ‘U’ shape. They are suitable for fixing onto timber
and metal stud walls, timber joists and wooden battens on ceilings.
SoundBreaker Bars are designed to reduce both airborne and impact
noise transfer between adjacent rooms by decoupling an existing
wall or ceiling from a secondary wall or ceiling.

Silver
Application
SoundBreaker Bars are used extensively on party walls and ceilings
of meeting rooms, offices, conference facilities, interview rooms,
classrooms, theatres, cinemas, studios, surgeries, clinics, hotels,
gymnasiums, dance studios and bedrooms.
Operating Temperatures
SoundBreaker Bars are suitable for use at normal building temperatures.
Compliance with Building Regulations
SoundBreaker Bars will assist in compliance with Approved Document
E of the Building Regulations effective from 1st July 2003.
Acoustic Performance
Incorporating SoundBreaker Bars to decouple an existing wall or
ceiling from a secondary wall or ceiling will improve the acoustic
performance by between 7 & 8dB. Detailed below are the acoustic
test results for a number of ‘typical’ constructions
incorporating SoundBreaker Bars. The constructions were tested
in NAMAS approved test houses.

Application and Fixing
Walls
When SoundBreaker Bars are used in a walling system, you must
be very careful in making sure they are attached correctly and
the right way round. The general consensus is to run the bars horizontally
across the wall with the narrow flange running along the underside
of the bar, allowing the separation to be created.
When fastening any materials to the face of the bars, fasten them
to the broad face at even points in the bar. Try to create an ‘interlocking’ effect
by fixing in between the fixings on the wall. (see diagram). When
working with a stud framework , fix in between the stud. Not doing
so could reduce the effectiveness.
Make sure when fixing the SoundBreaker Bars, to stop 10mm from
every edge. This is to reduce sound transmission ‘leakage’.
When fixing any materials or panels to the face of the bars, please
make sure to run a bead of flexible mastic along all the edges,
to seal of the materials and surfaces together.
Ceilings
For ceilings the principles above are the same, just remember
to keep all the channels facing in the same direction
