Absorption Materials

Absorption materials assist with Reverberation control is achieved by sound energy passing through a porous material, allowing the energy to be converted to heat and causing an effect called absorption.
To ensure that the porous acoustic core can operate correctly it is imperative that any external facing used, either for performance or aesthetic purposes, does not prevent the sound from passing through this medium. Stopping sound passing through will prevent the panel from being an effective absorber.

Wall Panels

Wall panels are used to help reduce sound reflecting off the walls and should be positioned at the area where the first reflections occur.

These panels tend to be fixed using a secret fixing or adhesive depending on the build up of the acoustic panels.

Most panels achieve a Class A rating at between 40-50mm. Manufacturers should be able to provide test information and results to confirm this. 

Designed to absorb sound these panels can be used in a variety of different applications such as:
– Classrooms, lecture theaters and other education related areas
– Industrial applications such as around noisy equipment or areas
– Offices, call centres and other sensitive work areas or zones
– Cinemas, restaurants and other places of entertainment
– Healthcare and other consultancy rooms or areas

 

Fabric wrapped, mineral fibre panels 
Mineral or glass fibre acoustic core finished with a fabric facing material to all visible edges that allows the panels to be installed individually.


Perforated steel panels
Perforated steel panels allow sound to pass through the robust facing material and the acoustic core is provided by using a mineral wool. Density of the core can vary but is usually around 45 – 60kg/m³ although it can be as dense as 140kg/m³ if required. Steel panels can be polyester powder coated to meet most available RAL colours.


Foam Panels
Lightweight open cell foam finished in an acoustically transparent fabric are ideal for bonding direct to the wall. Given the lightweight nature these are best utilised at high levels


Timber Panels
Decorative timber finishes in a variety of different veneers and slots or perforation types to suit most applications or finishes. The acoustic performance is provided through a mineral wool or foam fixed behind the timber panel  

Fabrics
Common fabrics used by manufacturers include Cara and Lucia range manufactured by Camira Fabrics.

Powdercoat
Most RAL or pantone colours are usually available from most manufacturers

Timber Panels
For available veneers or wood types please refer to the individual manufacturers specifications

Secret Fixing
These are commonly either split battens or other similar two part systems with one part fitted by the manufacturer to the panel and the second part fitted on site by the installer.


Impaling Spikes
These plates are fixed to the wall and the panels impaled on to the spikes. Please refer to manufacturers instructions when using these as an additional adhesive may be required to prevent movement.


Adhesive
Used in conjunction with a mechanical fixing for heavier panels or by itself for lightweight foam panels. The adhesive should have a good grab and short cure time to avoid supporting the panels for long periods of time

Ceiling Panels

Ceiling Rafts are used to help reduce sound reflecting off the ceiling and additional benefits can be achieved by introducing a void between the rear of the panel and the ceiling. These panels can also be fixed direct to the ceiling where space or designs require this.

These products tend to be fixed using an adhesive or suspension cable depending on the type of panel and finish being used. 

Most panels achieve a Class A rating at between 40-50mm. Manufacturers should be able to provide test information and results to confirm this. Ceiling

– Industrial applications such as around noisy equipment or areas
– Offices, call centres and other sensitive work areas or zones
– Cinemas, restaurants and other places of entertainment
– Healthcare and other consultancy rooms or areas

 

Direct Fixed
Normally a foam panel would be used to minimise weights given that an adhesive is used to fix these in place, although it is possible to use heavier panel types.


Ceiling Rafts
Designed to be suspended from the ceiling at levels to suit the design requirements. Ceiling rafts can be designed to include lights and speakers and are extremely versatile as an acoustic solution

Secret Fixing
These are commonly either split battens or other similar two part systems with one part fitted by the manufacturer to the panel and the second part fitted on site by the installer. When used in ceiling installations care must be taken over suitability of fixing to support the weight of the panel.


Suspension Cables
A wide variety of different suspension cable options are available from companies such as Gripple. Any system used must be tested by the manufacturer and safe working load values adhered to.
These systems are available in a wide choice of options including wire lengths, end fixings and loop or hook options for connecting the cable to the ceiling panel.


Adhesive
Used in conjunction with a mechanical fixing for heavier panels or by itself for lightweight foam panels. The adhesive should have a good grab and short cure time to avoid supporting the panels for long periods of time

Ceiling Baffles

Ceiling Baffles are used to provide a similar solution to ceiling rafts although by hanging the panels in a vertical orientation and in rows does increase the surface area of effective absorption. 

Baffles tend to be fixed using suspension cables although they can be fixed directly using different methods such as steel profiles designed to grip the baffles in place. 

Designed to absorb sound these panels can be used in a variety of different applications such as:
– Classrooms, lecture theaters and other education related areas
– Industrial applications such as around noisy equipment or areas
– Offices, call centres and other sensitive work areas or zones
– Cinemas, restaurants and other places of entertainment
– Healthcare and other consultancy rooms or areas

Baffles tend to be used in spaces with higher ceiling heights due to being hung in a vertical plane.

 

Direct Fixed
Manufactured from a variety of materials including rigid mineral fibre slabs, foam, polyester and steel, acoustic baffles are a versatile and effective acoustic solution.


Suspended
Suspended in rows or other patterns baffles can be used to form aesthetically pleasing finishes or align the panels with other elements in the ceiling space. Placing in rows or other patterns also allow for other services to be installed without competing for space with the acoustic treatment.


Bespoke Designs
Designs can be tailored to suit most requirements and include metal frame designs with bespoke acoustic treatments or shaped units that when hung from different heights can add features such as wave patterns to the finished installation

Anechoic WedgeAnechoic Wedges 
Are designed absorb sound and to prevent reflections from occurring by diffusing sounds from one wedge to another instead of travelling around the space and creating unwanted room modes.


Creating good acoustics with panels and raftsMusic Rooms

Profiled or plain absorbers located at key areas within a studio to ensure first reflections are controlled effectively to maintain the best possible acoustic environment for the production of music.


Mobile Screens and Partitions
Where fixed solutions are not a viable option then the materials can be mounted in movable solutions to ensure that you do not lose any of the acoustic performance required


Bespoke Designs
Designs can be tailored to suit most requirements just like sliding screens to cover windows in a conference room to reduce light levels whilst adding absorption to the room for clearer speech intelligibility.
