Finnforest is a wood products company delivering service-oriented solutions developed in

collaboration with its customers. Its premium solutions are based on ecological, high quality

Nordic wood as a raw material.

Wood is the only building material that is truly renewable, if well managed. Forest certification

schemes give assurance that the timber is legal and from sustainable sources. Finnforest UK

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 floor. 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.

REQUIREMENT

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 E stringent performance

requirements for the transfer of both Airborne

and Impact Sound, >45dB and <63dB respectively.

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.

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.

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

DEFLECTION LIMITS

During construction

• The dead load must be taken as the load of the floor at the

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 Gyvlon

screed. At 40mm nominal thickness this should be set to

0.99kN/m2. 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/m2. This allows for

the dead load of The SoundBar System and includes a

suspended ceiling system of 0.15kN/m2.

• The live load must be taken according to BS6399:Part 1 or

BSEN1991-1-1.

• A partition load of 0.25kN/m2 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).

Additional detailing

The SoundBar System allows for a suspended ceiling underneath the 2 layers of 15mm fire resistant

plasterboard. 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.

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 plasterboard 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

DO NOT install The SoundBar System across the

timber frame cavity to avoid cracking in case

differential settlement occurs.

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.

When services need to penetrate through The SoundBar System, there are two options:

98

Detail ST6 under construction

Detail ST6 finished

Party wall timber frame

Plasterboard rip

Timber batten to support threshold board and

SoundBar screed under construction (at least

75mm high)

Edging strip

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.

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 sound according to the building

regulations. 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.

Installation sequence

1. Installation of a 150mm plasterboard rip with 5mm gap

to the structural deck, so there is a solid back for the

SoundBar Gyvlon screed.

2.The SoundBar edge strip is installed with the self adhesive

backing against the plasterboard rip.

7. Fast application, up to 2000m2 per day. 8. 48 hours later screed is dry enough to walk on.

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 01205 883 835.

6. 40mm minimum SoundBar Gyvlon screed is then pouredand levelled.

Do’s and Don’ts

The SoundBar edge stripThis 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 Lafarge Gyvlon Installation Manual.

Please consult the RD handbook if you intend to register the

floors, and separating walls with RDL.

1. The floor is free of all debris and all holes in the structural

deck have been closed flush to the top of the deck.

2. The structure is wind and water tight.

3. The noggin or the proprietary metal strap is installed behind

the plasterboard rip.

4. The plasterboard rip is of the same thickness as the first

layer of plasterboard.

5. The threshold noggins and noggins around openings are

in place.

6. The SoundBar System edge strip has been installed.

The SoundBar BoardFor 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.

Before the installation of the acoustic board, please ensure:
