An attractive spray applied, medium texture. Ideal for use in sports halls, offices, classrooms, auditoria, theaters, etc.
Please note that it is important not to use moisture resistant plasterboard as this can cause staining of wet applied products. Oil based stain barrier paints can be used to prevent this. Please consult Oscar Acoustics for more information.
A minimum of 12.5mm thick plasterboard, installed to British Gypsum specification should be used.
Acoustic spray application by Oscar Acoustics trained in-house teams. Consult Oscar Acoustics for relevant acoustic plaster preparation details.
An attractive, seamless, spray applied acoustic finish with a medium texture for noise reverberation control. Naturally safe recycled cellulose fibre with low embodied energy. Spray applied directly onto gypsum board, concrete, steel sheet and most other surfaces. Can be applied to flat, domed vaulted, corrugated/ profiled and other shapes of ceiling. Can be disposed of as non-hazardous waste. An excellent alternative to acoustic panel ceilings without design compromise.
Features and benefits:
B-s1,d0 & Class 0 to BS476 - 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.
90% of flangeless fittings do not work properly with any acoustic finish. If you are specifying a flangless fitting, please contact Oscar Acoustics for advice.
Acoustic testing has been carried out against concrete. Substrates likely to provide increased performance include plasterboard with the use of an air gap behind, rib deck or profiled metal sheet. Please contact Oscar Acoustics’ technical department for free design assistance.
