Armourcoat Acoustic® Plaster System
The Armourcoat Acoustic® Plaster System is designed to optimize the acoustics of interior spaces, such as concert halls, lecture theaters, hotels, restaurants and lobbies, reception areas, shopping malls and public interior spaces of all types. The control of unwanted sound can create a more enjoyable experience for building occupants and more pleasant environment for visitors. Reflected sound, or reverberation, is now a well-accepted, but negative, by-product of using hard interior surfaces like polished stone, or areas of glass. Reflected sound waves can cause serious reductions in speech or amplified sound quality, which leads to an unpleasant experience for occupants of such spaces – both presenters and audiences. The Armourcoat Acoustic® Plaster System can provide a solution to interior noise problems, and also provide an aesthetically pleasing seamless, joint-free finish over large expanses, including both flat and curved surfaces.
Quiet, Comfortable Interiors The Armourcoat Acoustic® Plaster System combines the well-known insulation and sound absorption performance of mineral fiber baseboard with an elegant marble plaster finish. The finishing plaster is troweled on to provide a uniform seamless surface, yet it is thin enough to allow sound waves to pass through and be absorbed by the fibrous base layer underneath.
Armourcoat Acoustic® Plaster System can be pigmented to a range of standard or custom colors.
Excellent acoustic performance
The Armourcoat Acoustic® Plaster System has been tested in a Reverberation Chamber by the University of Southampton (ISVR Consulting) to BS EN ISO 354:2003 (Airborne sound absorption measured in a reverberation chamber), using a Type A mounting. The Armourcoat Acoustic® Plaster System achieved Noise Reduction Coefficients (NRC Ratings) to BS EN ISO 11654 of –
NRC 0.8 class C (30mm system).
NRC 0.9 class A (50mm system).
Excellent environmental performance
The mineral wool substrate used in the Armourcoat Acoustic System incorporate 70% recycled content. The plaster basecoat is made from expanded glass with 85% recycled content, and the topcoat plaster made from 80% recycled marble. The system contains no VOCs and is resistant to bacteria, mould and mildew.
Excellent thermal performance
Armourcoat Acoustic® mineral wool panels provide excellent thermal performance and red uce heat loss through the building envelope.
