THE SOUNDBAR®SYSTEM TECHNICAL GUIDE
The SoundBar System is a unique, total screeded flooringsolution which is the only system of its kind to haveachieved Robust Detail, E-FT-4. This provides thedeveloper with the confidence and assurance of achievinga performance standard over and above Part E of thebuilding regulations, two EcoHomes credits if registeredwith Robust Detail.
The SoundBar System delivers – providing a shallower,high quality, solid floor feel. Designed to improve upon theacoustic performance of a traditional timber floor. What ismore, the design, installation and total projectmanagement is controlled through one company.

THE SYSTEM
Sound reduction results
The SoundBar Systemcomprises 4 key components:
FINNJOIST (FJI)
Comprised of a high quality OSB web andKerto flanges.
SOUNDBAR EDGE STRIP
Foam edge strip designed to accommodate theSoundBar board.
SOUNDBAR BOARD
Two component 34mm thick acoustic board
SOUNDBAR GYVLON SCREED
Lafarge Gyvlon pump-applied self-levelling syntheticanhydrite screed.
INDICATIVE SOUND TEST RESULTS ACHIEVED ON SITE
TIMBER FRAME TIMBER FRAME TIMBER FRAME REQUIREMENT(JAN 2008) (FEB 2007) (APRIL 2006) PART E
Airborne Sound DnT,w+CTr >51dB >55dB >52dB >45dB
Impact Sound L’nT,w <56dB <52dB <53dB <63dB
Through rigorous laboratory tests, The SoundBar System exceeded Part Estringent performance requirements for the transfer of both Airborne andImpact Sound, >45dB and <63dB respectively.
On-site the results were equally impressive. Having performed over 19 livesite tests over a period of 33 months The SoundBar Systems laboratoryperformances transferred to site deliver outstanding results.
The table above provides an indication of performance over andabove Part E across various live sites, weather conditions andseasons. Each time The SoundBar System outperformed therequirements set down in Part E.
These results have been further supported by the achievement of aRobust Detail RD E-FT-4, the only hybrid I-Joist and screededflooring system to do so.

STRUCTURAL DESIGN
During the structural design, the structural engineeror building designer must check two different loadsituations; during construction and in general use.Both load cases are of importance and must beconsidered for the construction of The SoundBarSystem in order to get the required performance.They must also be registered and checked in orderto be covered by the BM-TRADA Certification.
NOTES: (L) Engineering span between supports(Uinst) Instantaneous deflection under live, partition and dead load(Ufin) Final deflection under live, partition and dead load(U1kN point) Deflection under 1kN point load (vibration criteria)
During construction
• The dead load must be taken as the load of the floor atthe time of the Lafarge Gyvlon screed installation.Usually this is 0.40kN/m2.
• The live load must be taken as the load of the Lafarge Gyvlonscreed. At 40mm nominal thickness this should be set to0.99kN/m2. The load should be patterned for continuousbeam members over internal supports.
• No other loads should be applied.
In general use
• The dead load must be taken as 1.75kN/m2. This allowsfor the dead load of The SoundBar System and includes asuspended ceiling system of 0.15kN/m2.
• The live load must be taken according to BS6399:Part 1or BSEN1991-1-1.
• A partition load of 0.25kN/m2 should be added when theexact location of non load bearing partitions is not knownor these can be moved during the design time of thebuilding (50 years).

ADDITIONAL DETAILING
In this situation, the pipe work is fitted with lagging of at least 10mmthickness before the installation of the acoustic board and the slip membrane.It is important that the screed is completely sound-isolated from thepenetrating pipe work and the lagging is above the final screed level.
When services need to penetrate through The SoundBar System, there are two options:
In this case, the service shaft is completely enclosed in a plasterboard shaft.The shaft is isolated from the rest of the structure to resist both fire and soundaccording to the building regulations.
Advice should be sought with regards to the resistance of fire. The riser shaft isbest constructed as a non load bearing construction with the wall sitting on thestructural deck of The SoundBar System floor.
INSTALLATION OF VERTICAL SERVICES
The SoundBar System allows for a suspendedceiling underneath the 2 layers of 15mm fireresistant plasterboard. In this suspended ceiling,all services can be horizontally distributed. Thereare no provisions made for services within thedepth of the screed or the acoustic board.

In timber frame buildings, the wall betweencommunal and residential areas are always builtin a party wall construction. This is a two leaf timberframe structural wall with plasterboard on theinside and an insulation quilt in between the wallstuds of each wall construction.

INSTALLATION SEQUENCE
1. Installation of a 150mm plasterboard rip with 5mm gap to the structuraldeck, so there is a solid back for the SoundBar Gyvlon screed.
2.The SoundBar edge strip is installed with the self adhesive backing against theplasterboard rip.
3. The board is installed tight against the edging strip, laid in a staggered pattern withno gaps between the boards.
4. A slip membrane with minimum 500µm thickness is laid, lapped and taped at theedges and the laps.
5. Install under floor heating at this point if required*.* The installation of underfloor heating will affect the depth of the screed. Please consult the technical team on 01205 883 835.
6. 40mm minimum SoundBar Gyvlon screed is then poured and levelled.

7. Fast application, up to 2000m2per day. 8. 48 hours later screed is dry enough to walk on.
DO’S AND DON’TSPlease consult the RD handbook if you intend to register the floors, and separating walls with RDL.
THE SOUNDBAR EDGE STRIP
This must always be continuous and shall have no gaps. When joining the edgestrip, please ensure an adhesive tape is used to link the two ends. Also ensure theapron and slip membrane are lapped according to the Lafarge GyvlonInstallation Manual.
• The floor is free of all debris and all holes in the structural deck have been closed flush to the top of the deck.
• The structure is wind and water tight.
• The noggin or the proprietary metal strap is installed behind the plasterboard rip.
• The plasterboard rip is of the same thickness as the first layer of plasterboard.
• The threshold noggins and noggins around openings are in place.
• The SoundBar System edge strip has been installed.
THE SOUNDBAR BOARD
For best use of material and least wastage on site the acoustic board should beinstalled in a brick pattern with the first row having the machine edge removed.
