The award winning concept in sound control

Initially launched by E-Cousti, with a range of products based around E-Cousti's innovative Membrane, withits wide range of solutions E-Cousti 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

E-Cousti solutions have been rigorously tested by BRE and SRL at independent laboratories to ensure that each product has the necessary performance levels.

Environmently aware

E-Cousti 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.

E-Cousti Membrane

The membrane is the original E-Cousti product, which was developed using a nano vacuum technology to attenuate sound.

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.

 

E-Cousti Ecobase

A 5mm closed cell, cross linked, foam polyethylene layer with a density of 33kg/m3. High compressive strength and water resistance.

Can be lapped over at wall junctions, forming an integral flanking strip. Supplied in rolls of 5mm x 30m x 1.85m.

 

E-Coustiwrap

The E-Cousti Membrane is sandwiched between two layers of 25mm mineral wool with a reinforced aluminium foil facing on one side. Suitable for the thermal and acoustic insulation of air ducting, pipes and enclosures.

Supplied individually in various sizes.

E-Cousti Joist Cap

Acoustic joist treatment, comprising a polyethylene foam designed to friction fit onto joists.

Supplied individually at 12mm x 50mm x 2m. Patent application number 0614487.7

E-Coustiquilt

The E-Cousti Membrane is sandwiched between two layers of 25mm mineral wool for maximum effectiveness.

Overall thickness of 52mm and is supplied in rolls of 5m lengths and 1200, 600, 400mm widths.

E-Cousti Ecostrip

Comprises a cross linked, closed cell polyethylene foam. Installed at the floor and wall perimeter.

Provides an optimum seal to eliminate sound transmission.

Supplied in rolls of 5mm x 100mm x 20m.

 

 

E-Coustifloor

Comprises 6mm laminate of E-Cousti Membrane and 5mm closed cell foam.

Can be lapped over at wall junctions, forming an integral flanking strip. Supplied in rolls of 6mm x 7.5m x 1.5m.

 

E-Cousti Ecoboard

Comprises 18/22mm P5 tongued and grooved chipboard laminated to 5mm closed cell, cross linked polyethylene foam.

 

High compressive strength and moisture resistance.

Supplied in 23/28mm x 2400mm x 600mm boards.

 

 

E-Cousti Direct

Comprises a layer of 22mm P5 tongued and grooved chipboard laminated to a layer of 5mm closed cell polyethylene foam bonded to a 1mm layer of E-Cousti Membrane.

Supplied in 28mm x 2400mm x 600mm boards.

 

E-Cousti Fix & Seal

A specially formulated intumescent and acoustic sealant to be used with all E-Cousti solutions.

Supplied in tubes of 900ml.

 

 

 

Glossary

As one reads through the E-Cousti pages, a pletherae 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.

Internal Wall

Any wall that does not have a separation function.

LnTw

The measurement used to measure the impact sound insulation of floors (on site). Lnw = laboratory testing

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

Wall that separates adjoining dwellings, houses, flats or rooms.

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 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.
