ECHOSORBA ™ stick-on acoustic panels are extremely high performance sound absorption panels. Their lightweight properties and low thickness not only make the panels easy to install but extremely suitable for adhering to a wide range of ceiling and wall surfaces.

These sound absorbing panels are used widely in schools, offices, music studios, lecture theatres, multi purpose halls, interview rooms, training areas and cinemas. They meet the requirements of BB93 of the Building Regulations for acoustics in school buildings and are Class 0 fire rated hence meeting the Fire Regulations as well.

Acoustic Performance

Class A

This fixing method results in very high sound absorption especially at low frequencies which is often very difficult to achieve. This product achieves an absorption coefficient of 1.00 (i.e. 100%) even as low as 160 Hz. This provides a very cost effective bass absorber for studios and music rooms at minimal cost.

The air gap can be created by using 100mm thick timber battens behind the panels or a similar method.

Sound Absorption Panels

Class C

The special construction of ECHOSORBA panels gives a very high sound absorption rating 0.85 (i.e. 85%) with minimum headroom height loss (only 30mm).

Sound Absorbing Panels

The NRC of a standard panel is 0.85 (i.e. 85%) and an emulsion painted surface panel is also 0.85 (i.e. 85%). The only difference is that the thin coating of emulsion paint on the surface acts as a membrane absorber leading to higher absorption at the lower frequencies and a drop off at the higher frequencies. However the overall NRC stays the same at 0.85 (i.e. 85%).

Acoustic Performance for Echosorba


ECHOSORBA acoustic panels are simply adhered to ceilings and upper walls using Gluesorba Contact spray can adhesive.

It is important to check the construction detail of the backing surface structure (ceiling or wall) to which the acoustic panels are to be glued. The ECHOSORBA panels have a thermal conductivity of 0.034 W/mK at 10°C and therefore have good thermal insulation properties as well as excellent sound absorption.

It is therefore important to ensure that there is no possibility of condensation or cold bridging occurring if the acoustic panels are applied to the surface of the structure. Should there be any potential for condensation or cold bridging, then it is very important that this problem is eliminated by suitable treatment, such as a vapour barrier etc, before the ECHOSORBA acoustic panels are installed.

Failure to take suitable precautions may lead to staining of the acoustic panels due to air and moisture movement. This can potentially occur, for example, where there is no heated upper floor above the ceiling to which the acoustic panels are to be fitted. Soundsorba Ltd will not be liable if these precautions are not taken and staining occurs.

Gluesorba contact adhesive is a quick spray-on application which comes ready to use in 500ml spray cans. The panels and adhesive must be kept and stored inside at room temperature at all times and acclimatised in the area where they are to be used for 24 hours before installation.

The panels are adhered to the backing surface either with a butt joint effect or by using shadow gaps. To avoid soiling the panels, white cotton gloves should be worn when handling them.

The backing surface must be clean, flat, level, dry, solid and free from dust, oil, grease and other similar residue which may affect the adhesion. We recommend that the contact adhesive is applied at room temperature of approximately 21°C and in well ventilated conditions.

Echosorba Installation for Acoustic PanelsThe contact adhesive has to be applied to both the panel and the ceiling surface in a web type pattern. The spray adhesive should be held 150mm to 300mm away from the surface and at a constant 90 degree angle. To avoid overspray onto the edges of the panel or other surfaces, it may be necessary to mask any vulnerable areas.

The panel and ceiling surfaces should be fully coated and then allowed to dry for 3-5 minutes before bonding the surfaces together. The panels should be placed accurately into position as the adhesive creates an immediate bond upon contact. Once the panel is in place it should be pressed firmly to ensure overall contact.

We recommend a test adhesion is carried out to full satisfaction, before proceeding with the full installation. Coverage should be 100%. Each 500ml spray can covers approximately three panels on both surfaces, depending on workman and backing surface.
