Quiet spaces without design compromise

A visually appealling interior with simple surfaces such as wooden or stone floors and plain flat walls may not be the most pleasurable place to spend time due to poor acoustics.  This same visual impact combined with a calm acoustic ambience is made possible with Oscar Elite. The exceptionally smooth acoustic plaster is spray applied to create a seamless acoustic ceiling for optimal reverberation control.

Unlike traditional plaster our Oscar Elite synthetic, A2-s1,d0 & Class 0 fire rated acoustic plaster, absorbs sound energy instead of reflecting it, reducing reverberation times and overall noise levels within a space, giving all important clarity to speech and music.

When designing One Mabledon Place (pictured above), Steffian Bradley Architects required the smoothest of acoustic plaster finishes, to not only realise the minimal design intent but also treat the noise reverberation issue in the large open space.  Oscar Elite was specified and expertly applied by our specialist in-house installation team achieving superb acoustic results without design compromise.  

Fire rated acoustic plaster

All our products significantly better the new fire requirement required under the updated Approved Document B.

Its Class 0 to BS476 & A2-s1,d0 fire rating provide significant benefits over the new Approved Document B requirements by providing little to no smoke and absolutely no droplets, assisting in the safe escape of occupants. 

Note:   Always insist on obtaining a copy of the fire test report before using a product.

Acoustic plaster testimonials

"Oscar Elite is the perfect acoustic product: effective and completely invisible; it delivers the perfect customer experience."

Noam Bar
5 star review rating  

"Yotam Ottolenghi used Oscar Acoustics to render shiny surfaces softly spoken."

Oscar Acoustics are very proud to have been mentioned in the Evening Standard, for the superb acoustic result achieved in the beautiful restaurant NOPI by using our exceptionally smooth Oscar Elite acoustic plaster.

Fay continues...

“It’s time to talk about noise in restaurants…I don’t always – just sometimes – harp on about the unpleasantness of sound ricocheting off unforgiving surfaces, thumping music shivering your timbers and having to give up on the idea of conversation with dinner.  Hiring an acoustic engineer when a new restaurant is planned is an expensive move but two of the most successful operators I know make it top of their list of priorities.”

45 Jermyn St, London - Restaurant Acoustics

45 Jermyn St

For this exquisite dining room, the restaurant and bar acoustics had to be dealt with using cutting edge acoustic plaster technology so as to not compromise any of the design brief.  Martin Brudnizki Design Studio wanted to redesign Fortnum & Mason’s original Fountain Restaurant with a design that fused the glamour of contemporary London with the heritage of the truly iconic department store.

NOPI Restaurant - Restaurant Acoustics

NOPI Restaurant

When designing Nopi, the owner Noam Bar had a clear vision: plaster smooth ceilings, painted brick and tiled walls, hard table tops and marble floors; poor restaurant acoustics were a certainty.

Oxford New College - College Acoustics

Oxford New College

The main dining hall in the original wing of this New College building had always suffered from poor school acoustics, with escalating noise levels when fully occupied.  Meal times were unnecessarily stressful and potentially damaging to the hearing of all those in attendance, including the serving staff.  Oscar Elite was presented to Oxford New Colleges’ committee as a product that would be in keeping with the centuries old building and it was well received because Oscar Elite appears as a normal flat white acoustic plaster.

Holborn Dining Room, Rosewood Hotel, London - Restaurant Acoustics

Holborn Dining Room acoustics

Oscar Elite installation structure

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, trained staff in order to guarantee optimal workmanship.

  • 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.

Bonding to substrate

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 products ability to be sanded into smooth shapes.

Specification assistance

  • BIM Objects available
  • Included within all NBS software.
  • Standard details drawings for most situations.
  • Bespoke detailing solutions possible.
  • Recessed & surface mounted items possible.

Maintenance & cleaning

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 of the product.

Repairing & servicing

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 items

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.
