Product Information

Karma Acoustic Solutions have taken over E-Cousti Acoustic Innovation

The award winning concept in sound control

Initially launched by E-Cousti, with a range of products based around E-Cousti's innovative Membrane, with its wide range of solutions Karma is now established as a market leader within its field and offers a wide range of competitively priced, acoustic solutions for both new build and refurbishment projects for walls, partitions, floors and other structural applications.

Tested performance

Karma Acoustic Solutions products have been rigorously tested by BRE and SRL at independent laboratories to ensure that each product has the necessary performance levels.

Environmentally aware

Karma have striven to design and develop products that re-use secondary raw materials, are based on renewable resources, are themselves recyclable, and where they are not, can be safely disposed of without harm to the environment.

Karma Membrane

sound reduction insulation membrane solution

Original product was developed using a nano vacuum technology to attenuate sound. This patented technology only is only 1.2mm thick based on synthetic rubber. It is supplied in rolls of various sizes. Patent number: EPC (UK) 1173503.

E-Cousti Membrane Awards Profile

European Merit Award Winner for Research & Technology
1999-2001 European Award for Support for Products Under Research
2002-2003 DTI Most Innovative SME Award.2000
Arena Network Most Promising Environment Products Award 2005

Applications

The Karma / E-Cousti Membrane as well as being a stand-alone product, is an integral part of certain Karma / E-Cousti products, such as E-Coustiquilt, E-Coustifloor, E-Coust Ecoboard, and E-Cousti Direct.

As a stand alone product, the E-Cousti Membrane can be used to improve acoustic insulation values and effectiveness in numerous ways.

For example, dramatic improvements in sound insulation can be achieved in the following applications ...

Noise penetration through existing walls or ceilings

Applying an Karma / E-Cousti Membrane to existing walls and/or ceilings, then add Knauf Soundshield Plasterboard, or similar interior wall cladding.

Noise penetration through existing floors

Cover existing floors with Karma / E-Cousti Membrane, then cover with new flooring materials such as floor boards, parquet, laminate flooring, et cetera

Clearly there are numerous applications that can benefit from the application of Karma / E-Cousti Membrane, and as visitors view the applications on the following pages, they may identify retrofitting situations where the application of Karma / E-Cousti Membrane may suffice, rather than buying a complete solution such as Karma / E-Cousti Direct.

Installation advice

There ever possible, stagger the joints if double layering of plasterboard is required.

Ensure boarding goes all the way down to the floor and all the way up to the top even if skirting or a cornice covers it. And, for optimum performance use sealant on the joints.

Light or plug sockets should not be placed back to back otherwise the sound will go straight through the structure. Around the sockets, to maintain integrity, use intumescent putty seal which swells as a result of heat exposure, thus increasing in volume, and decreasing in density. Intumescents are typically used in passive fire protection. Pay particular attention to the end detail of wall and floor junctions.

Standards of workmanship

Attention to detail is absolutely essential, to ensure that a soundproof structure is performing to its maximum level great care must be taken in its construction.

It must be built as if it needed to be waterproofed - as sound, like water, light or air - will find the smallest crack and expose it as a weak part in the structure.

Any gap or hole will significantly impair the construction’s performance. A single 25mm hole in an otherwise acoustically sound partition can reduce performance by up to a massive 15 dB.

Although a 25mm hole should be visible a crack 1mm x 1m will not always be obvious, and if this is not treated correctly with an acoustic sealant it will be detrimental to the structure.

Please remember that an acoustic construction is only as good as its weakest link.

This patented technology (Patent number: epc (UK) 1173503) results in a 1.2mm thick product based on synthetic rubber and is supplied in rolls of various sizes.

Glossary

As one reads through the Karma / E-Cousti pages, a plethora of new terms and abbreviations will be encountered. In an attempt to decipher some of the terms and abbreviations we have reproduced an alphabetical list of definitions ...

Building Element

Walls, floors and roofs etc.

Ctr

The correction to a sound insulation quantity to take into account low frequency noise.

Decibel (dB)

The most commonly used unit to measure sound.

DnTw

The measurement used to measure the airborne sound insulation between two rooms (on site).

DnTw+Ctr

See above, but with the low frequency correction factor included.

Flanking Transmission

Sound transmitted between two rooms using an indirect path i.e. the top or bottom of a separating wall (see further details below).

Frequency

The number of pressure variations per second that gives a sound its distinctive tone. Hertz (Hz) The unit of the frequency of the sound.

Impact Sound

Sound resulting from direct impact on a building element.

Internal Floor

Any floor that is not a separating floor.

ΔLw

Denotes the measured improvement of impact sound insulation resulting from the installation of a floor covering or floating floor.

Pre-Completion Testing (PCT)

A new requirement to Part E where structures not conforming to the RD (Robust Detail)will be tested prior to completion to check they reach the required standards.

Robust Detail (RD)

A collection of pre-approved constructions that, if used, negate the need for PCT.

Rw

The measurement used to rate the sound insulation of a material or building element in a Laboratory.

Separating Floor

Floor that separates flats or rooms for residential purposes.

Separating Wall

Sound Reduction Index (SRI)

A quantity measured in a laboratory that characterises the sound insulation properties of a material or building element in a stated frequency band.

Disclaimer

The Karma / E-Cousti product range and solutions provided within this web site, have been tested to BS EN ISO 140 series and BS EN ISO 717 series to meet the requirements of Approved Document E.

Actual acoustic values achieved are a result of rigorous independent laboratory testing to the highest standards, However, variances in performance on site may result, due to workmanship or other external factors that cannot be fully modelled within laboratory conditions.

Consequently it is important to note there is no product, system, manufacturer or supplier that can offer any guarantee of performance, hence the requirement for Pre-Completion Testing.

It is therefore advisable to choose a solution that exceeds the acoustic requirement to limit the potential impact of site variances that may occur, or seek advice on your individual situation. All testing shown in this guide was undertaken of either the B.R.E. or S.R.L. which are both UKAS accredited bodies.
