SPP Acoustic panelling is used in a wide variety of environments to adjust, treat and improve the acoustic levels within the area.
Often used within theatres, sports halls, gymnasiums, concert halls and various public spaces, our boards offer a solution to the acoustics, as well as providing a bespoke decorative finish to any room.
Available in a range of plywood with natural finishes in birch, pine, poplar and beech. Alternatively, our engineered range offers veneers, laminates and melamine finishes.
By combining our acoustic knowledge with joinery expertise we can supply a broad range of specifications and application requirements.
Birch plywood is ideal for sports areas due to its strength and impact resistance

Finishing

Fire Rated Maintaining Lacquer
Contra-Burn® lacquer is offered in a matt finish to provide a natural touch.
This maintains the EN13501-1 fire rated standard that is required in most new projects.
Matt or gloss high strength lacquer provides a tactile finish to enhance and protect the panel.
Standard Lacquer
Acoustic Fleece

Borders
A black viscose / polyester sheet bonded to the reverse
Fibre-glass free, 180 microns, weighing 50g/m2
Flame retarding class B1
Offered square edged as standard
Loose tongue & groove or chamfered available on request
Factory finishing of edges available if required
50mm borders is the default size
Uniform border widths across different panel sizes create a visually pleasing finish
Solid Panels
Fixing
Battens
Laboratory Measurement of
Random Incidence Sound Absorption to BS EN ISO 354:2003
Tests & Standards
We can supply plain panels to compliment and contrast the acoustic panels.
These panels will be the same production as the perforated panels and undergo the same finishing process to ensure consistency of colour, sheen and texture.
On larger scale projects, we can offer contrasting solid panels to provide a visual break. This could be melamine, veneered or painted finishes.
Screws
Using a stainless steel screw and washer on the border edge of the panels at 300mm centres (24 fixings on outer border). This method makes a feature of the fixing and ideal if panels need removing to access ME services.
Pinning
Using a lost head nail to secure directly into supporting studwork behind at 300mm centres across all areas of the panels. This method provides a clearer face and a permanent fixing method.
Aluminium Split Battens
A heavy-duty and robust split batten ideal for sports hall or heavy traffic areas where an accessible panel is required.
Timber
40-45mm thick. Standard construction CE marked timbers are generally used working to industry standard timber subframe requirements. This can be supplied as square or to a split batten detail to offer hidden fixing.
Machined Plywood
18mm thick Contra-Burn treated plywood. Best of both worlds: thin and strong, but lightweight and eco-friendly.

Sound Absorption
Independently tested standard perforations to meet BS 8233:2014. We work with clients, architects and designers to achieve the acoustic rating and visual aesthetics required for the project.
Acoustic absorption is achieved by sound waves passing through the open area in our panels and baffled by the acoustic fleece behind. Our standard range of machining patterns achieves a high Class C rating (with potential for a higher rating using bespoke machining or additional insulation behind the panels)
ISO 11654:1997 Acoustics – Sound absorbers for use in buildings – Rating of sound absorption
Testing terminology - BS EN ISO 354:2003 Acoustics. Measurement of sound absorption in a reverberation room
The material’s ability to absorb sound is generally presented with absorption coefficients measured in different frequencies. This means in practice that one material has a number of different absorption coefficients based on frequencies.
When specifying a suitable absorption class for each product, a product is first measured according to EN ISO 354:2003. The result from this test is an absorption curve, which declares absorption coefficients for each frequency used in the test.
Fire Retardancy
When looking at a project the risk of fire is a key focus point for any design. With the harmonized standards of BS EN 13501 construction products are classified dependent upon their risk, with A being non combustible and F being flammable.
Within every build there is a requirement to meet a minimum standard with a requirement of Euro Class B in most non residential projects such as sports halls and education facilities. This is also combined with a minimum standard for smoke graded from 0-3 and flaming droplets graded from 0-3.
Due to our experience within the fire retardancy market we can offer over 90% of our panel options to Euro B-s2,d0 where fire protection is required. Our system is independently tested and we can offer compatible finishing coatings to offer a product that will last the test of time.
The standard will be displayed as Euro B-s1,d0
Fire Classification Details
Panels
Every panel we supply is subject to a wide range of testing requirements including:
Environmental Rating
All boards comply to both EUTR and UKTR requirements and where required can be offered as FSC or PEFC certified.
Board Structure
This includes a declaration of performance from the producing mill and contains key information such as glue type, board strength, board density and use class.
Face Grades
We offer our panels with defined face grades, these meet set standards in terms of appearance and have guidelines on allowable natural defects such as knots, fillers and colour variation.
Additional Services
For over 25 years we have supplied acoustic sheet material to the market. We know that service and experience is just as important as the high quality product supplied for your project.
