E-Cousti Membrane

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.

Applications

The E-Cousti Membrane as well as being a stand-alone product, is an integral part of certain E-Cousti prducts, 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 E-Cousti Membrane to existing walls and/or ceilings, then add Knauf Soundshield Plasterboard, or similar interior wall cladding.

Noise pnetration through existing floors

Cover existing floors with 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
E-Cousti Membrane, and as visitors view the applications on the following pages, they may identify retrofitting situations where the application of E-Cousti Membrane may suffice, rather than buying a complete solution such as 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 shold 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.
