Sound Proofing Ceilings: SoundBreaker Bars Specification

SoundBreaker Bars

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.

Colour
                                 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.
