acoustic plaster features and benefits
- A2-s1,d0 & Class 0 fire rated to BS476. Fire reports available on request.
- Achieves M1 certification for Building Materials emissions.
- Increases productivity by creating a calm and pleasant acoustic environment.
- Can be directly applied to most substrates such as wood, gyproc board, steel sheet, smooth concrete and more.
- Suitable for flat, domed and vaulted soffits.
- Quick and easy to install.
- Easy to maintain through vacuuming or dusting.
- Available in two surface finishes in a variety of colours.
- The standard white finish provides a light reflectivity of 94%.
- Acoustic plaster installations are applied at 25mm thick; the area is dependent on the acoustical requirements of the project. An air gap is introduced to achieve high absorption at low frequencies.
- Can be over-sprayed in a different colour if required.
- Oscar Elite is approved by English Heritage.
Oscar Elite
technical specifications
The 27mm construction consists of 2mm adhesive, 20mm thick mineral board, base and top coat Oscar Elite synthetic acoustic plaster totalling approximately 5mm, which is sprayed, trowelled and worked to optical requirements. The finish is visually hard and firm to the touch but with excellent sound absorption. As with all acoustic plaster, installations should be suitably protected in areas where damage is likely.
Oscar Elite acoustic plaster is installed by our own in house, specialist trained staff in order to guarantee a finish to the highest standards and an installation that lasts as long as required.

Significantly betters the requirements of the new Approved Document B providing little to no smoke and absolutely no droplets, assisting in the safe escape of occupants.
- Achieves M1 certification for Building Materials emissions.
- Recycled content: Glasswool: 75%.
- Recyclability: Disposal in accordance with local recycling/disposal rules.
- Embodied carbon: Can effectively lower the carbon footprint of a building project by sequestering rich stores of carbon for the life of the structure or application.
Oscar Elite can be applied onto plasterboard or directly onto concrete. Adhesion to other surfaces is possible; please contact Oscar Acoustics for advice. Domes & barrel vaults are not a problem due to the product’s ability to be sanded into smooth shapes.
- BIM Objects available.
- Included within all NBS software.
- Standard details drawings for most situations.
- Bespoke detailing solutions possible.
- Recessed & surface mounted items possible.
Dust is removed by lightly brushing or vacuuming with a soft brush head. It is also sometimes possible to blow dirt from the surface with a high pressure air hose. A wall or a ceiling can be entirely over sprayed in acoustic plaster in the same or a change of colour. Over painting must be done by spraying and not roller to prevent serious impact on the acoustic performance and damage to the product. Advice must be sought from Oscar Acoustics before painting, as incorrect application can result in damage to the product.
A major benefit of Oscar Elite is its ability, in most cases, to be locally repaired within reason, negating the need for expensive and inconvenient pre-handover resprays, as with many products similar in appearance. For more serious damage, it is possible for us to lightly sand and reapply the top coat.
Recessed services e.g. spot lighting will require a halo spacer to match the material depth. Oscar Acoustics manufacture and install stainless steel halo spacers (drawing available) to the same size as the hole cut out. Stop beads may be required around openings, which again we can supply and install. Specially designed access hatches are also available through Profab, enabling the Oscar Elite to continue across the hatch door.
Problems can arise from using other hatches. These items are at extra cost and are to be purchased direct from the Profab. Please contact Oscar Acoustics for details and item code. Surface mounted fittings e.g. hanging/pendant lights will require pattresses to match the material depth. Please contact Oscar Acoustics for further advice.
Please Note: 90% of flangeless fittings do not work properly with any acoustic finish. If you are specifying a flangeless fitting, please contact Oscar Acoustics for advice.
Our technical department offer free advice and acoustic calculations on the use of our products.

Acoustic plaster test DATA certified by TNO Technology University Delft NL. Acoustic testing has been carried out against solid concrete. Increased performance can be achieved when applying onto plasterboard with an air gap.
The standard colour is arctic white. For bespoke colours, please send us your colour requirement using a Dulux paint reference or RAL. If over painting, please contact Oscar Acoustics for instructions first.

acoustic spray plaster featured on grand designs
Architects and interior designers who incorporate Oscar Elite into their designs can achieve spatial design with minimal hard, smooth surfaces without compromising the acoustic ambience. This was the case with the Holland Park Grand Designs house in London series 7 episode 16 (pictured right).
During refurbishment, acoustic spray plaster was applied to the ceiling and inside the light well, resulting in superb acoustics without compromising the beautiful, flat and smooth surfaces. Oscar Elite was selected for its super smooth, seamless finish and exceptional sound absorbing properties.

acoustic plaster frequently asked questions
Acoustic plaster is a form of plaster that contains particular fibres that have sound absorbing properties. Once applied, acoustic plaster absorbs sound energy in a space, significantly reducing reverberation (echo) and limiting unwanted noise.
Yes, acoustic plaster helps with reverberation. If you’re hoping to use regular plaster and achieve quality acoustics, you might end up disappointed. With Oscar Elite, you can be sure that you’re using a high quality acoustic plaster solution in your spaces.
