1 The SoundBar System HIGH PERFORMANCE ACOUSTIC FLOORING SOLUTION

2 THE SOUNDBAR SYSTEM TECHNICAL GUIDE The SoundBar System is a unique, total screeded flooring solution which is the only system of its kind to have achieved Robust Detail, E-FT-4. This provides the developer with the confidence and assurance of achieving a performance standard over and above Part E of the building regulations, two EcoHomes credits if registered with Robust Detail. The SoundBar System delivers providing a shallower, high quality, solid floor feel. Designed to improve upon the acoustic performance of a traditional timber floor. What is more, the design, installation and total project management is controlled through one company.

On-site the results were equally impressive. Having performed over 19 live site tests over a period of 33 months The SoundBar Systems laboratory performances transferred to site deliver outstanding results. The table above provides an indication of performance over and above Part E across various live sites, weather conditions and seasons. Each time The SoundBar System outperformed the requirements set down in Part E. A REVOLUTIONARy ACOUSTIC FLOOR SOLUTION FOR COmpARTmENT FLOORS These results have been further supported by the achievement of a Robust Detail RD E-FT-4, the only hybrid I-Joist and screeded flooring system to do so. 04 THE SOUNDBAR SYSTEM HIGH PERFORMANCE ACOUSTIC FLOORING SOLUTION

5 STRUCTURAL DESIGN During the structural design, the structural engineer or building designer must check two different load situations; during construction and in general use. Both load cases are of importance and must be considered for the construction of The SoundBar System in order to get the required performance. They must also be registered and checked in order to be covered by the BM-TRADA Certification. Loading and deflection limits During construction The dead load must be taken as the load of the floor at the time of the SoundBar installation. Usually this is 0.40kN/m 2. The live load must be taken as the load of the SoundBar. At 40mm nominal thickness this should be set to 0.99kN/m 2. The load should be patterned for continuous beam members over internal supports. No other loads should be applied. In general use The dead load must be taken as 1.75kN/m 2. This allows for the dead load of The SoundBar System and includes a suspended ceiling system of 0.15kN/m 2. The live load must be taken according to BS6399:Part 1 or BSEN A partition load of 0.25kN/m 2 should be added when the exact location of non load bearing partitions is not known or these can be moved during the design time of the building (50 years). LOADING LOAD TYPE DURING CONSTRUCTION DURING CONSTRUCTION Dead load (kn/m 2 ) Partition load (kn/m 2 ) Live load (kn/m 2 ) 0.99 (40mm) According to BS6399:1 or BSEN DEFLECTION LIMITS BS5268 AND NHBC TECHNICAL STANDARD IMPROVED BS5268, BSEN AND NHBC TECHNICAL STANDARD Uinst L/333 or 12mm L/350 or 12mm Ufin L/200 Refer to NA to BSEN U1kN point - Refer to NA to BSEN Lowest natural frequency - >8Hz Under Construction Uinst L/333 or 5mm L/333 or 5mm 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) HIGH PERFORMANCE ACOUSTIC FLOORING SOLUTION THE SOUNDBAR SYSTEM 05

8 ADDITIONAL DETAILING INSTALLATION OF VERTICAL SERVICES The SoundBar System allows for a suspended ceiling underneath the 2 layers of 15mm fire resistant. In this suspended ceiling, all services can be horizontally distributed. There are no provisions made for services within the depth of the screed or the acoustic board. When services need to penetrate through The SoundBar System, there are two options: A. DECOUPLED RISER SHAFT / LARGE PIPE PENETRATION In this case, the service shaft is completely enclosed in a shaft. The shaft is isolated from the rest of the structure to resist both fire and sound according to the building regulations. Diameter of pipe > Ø 30mm Pipe boxed in with two layers of Gypsum-based board combined nominal 16kg/m 3 Advice should be sought with regards to the resistance of fire. The riser shaft is best constructed as a non load bearing construction with the wall sitting on the structural deck of The SoundBar System floor.

SMALL PIPE PENETRATION In this situation, the pipe work is fitted with lagging of at least 10mm thickness before the installation of the acoustic board and the slip membrane. It is important that the screed is completely sound-isolated from the penetrating pipe work and the lagging is above the final screed level. 2 x 12.5mm fire resistant s 10mm SoundBar perimeter edge strip Plasterboard rip panel same thickness as 1st layer of Diameter of pipe < Ø 30mm joint.

9 FLATS AND COMMUNAL AREAS In timber frame buildings, the wall between communal and residential areas are always built in a party wall construction. This is a two leaf timber frame structural wall with on the inside and an insulation quilt in between the wall studs of each wall construction. The party wall construction is usually breached with the entrance door to the flats DETAIL ST6 UNDER CONSTRUCTION Party wall timber frame Plasterboard rip threshold board and SoundBar screed under construction (at least 75mm high) Edging strip DETAIL ST6 FINISHED Threshold board The timber batten has been removed and cut so the threshold board sits flush with the final screed level on both the communal and flat area. DO NOT install The SoundBar System across the timber frame cavity to avoid cracking in case differential settlement occurs. HIGH PERFORMANCE ACOUSTIC FLOORING SOLUTION THE SOUNDBAR SYSTEM 09

10 INSTALLATION SEQUENCE 1. Installation of a 150mm rip with 5mm gap to the structural deck, so there is a solid back for the SoundBar Enhnaced Binder screed. 2.The SoundBar edge strip is installed with the self adhesive backing against the rip. 3. The board is installed tight against the edging strip, laid in a staggered pattern with no gaps between the boards. 4. A slip membrane with minimum 500µm thickness is laid, lapped and taped at the edges 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 mm minimum SoundBar Enhnaced Binder screed is then poured and levelled. 10 THE SOUNDBAR SYSTEM HIGH PERFORMANCE ACOUSTIC FLOORING SOLUTION

DO S AND DON TS Please 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 edge strip, please ensure an adhesive tape is used to link the two ends. Also ensure the apron and slip membrane are lapped according to the Soundbar Enhanced Binder supplier Gyvlon/Gypsol Installation Manual. DO... THE SOUNDBAR BOARD For best use of material and least wastage on site the acoustic board should be installed in a brick pattern with the first row having the machine edge removed. DO... DON T... DON T... Before the installation of the acoustic board, please ensure: 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 rip. The rip is of the same thickness as the first layer of. The threshold noggins and noggins around openings are in place. The SoundBar System edge strip has been installed. HIGH PERFORMANCE ACOUSTIC FLOORING SOLUTION THE SOUNDBAR SYSTEM 11
