The Armourcoat Acoustic® Plaster System is designed to optimise the acoustics of interior spaces. From restaurants, theatres, offices, classrooms, hotel receptions and private residences the use of hard sound reflective surfaces such as glass, wood and stone can cause excessive sound reverberation which leads to unpleasant noise levels. The correct control of sound can create a calmer and more pleasant environment. The Armourcoat Acoustic® Plaster System offers a clean flat and smooth mineral surface that can be applied seamlessly over large expanses to both flat and curved surfaces and offers excellent sound absorption.
Armourcoat Acoustic® is suitable for use in both commercial and residential interior projects including; major transport hubs, restaurants, bars and nightclubs, cinemas and theatres, shopping centres and retail units, leisure facilities such as swimming pools and gymnasiums, open plan office environments, corridors and walkways, toilet and washroom lobbies, music rooms, open plan entrance halls and living spaces.

The Armourcoat Acoustic® Plaster System comprises of a special mineral wool composite panel that is bonded onto the substrate and finished with a seamless layer of the Armourcoat Acoustic plaster. Armourcoat’s considerable expertise in the formulation of marble based plaster finishes have created an elegant finish that appears smooth and even but still allows sound energy to pass through the surface. This enables sound to be absorbed and attenuated in the layer of mineral wool beneath. The Armourcoat Acoustic® Plaster System can be pigmented to a range of standard or custom colours. Firmly established as a recognised and approved acoustic system in the UK, worldwide availability is currently being implemented.
Excellent acoustic performance
Independent tests were carried out in the UK on the Armourcoat Acoustic® Plaster System to determine the Sound Absorption Coefficient (αs), conducted in accordance with European Standard EN ISO 354. Single figure ratings of sound absorption performance, known as the Weighted Sound Absorption Coefficient (αw) and Sound Absorption Class, are derived from these measurements in accordance with European Standard EN ISO 11654. Tests were carried out by the AIRO Acoustics Laboratory, a UKAS accredited testing laboratory No. 0483, on 18th December 2019. The Armourcoat Acoustic® Plaster System achieved BS EN ISO 11654 'NRC' ratings from 0.85, class B (28mm system) to 0.95, class A (48mm system). System meets and exceeds requirements under Part E Building Regulations 2010 for acoustic treatment in common areas of residential buildings (E3 section 7).
Excellent environmental performance
Armourcoat Acoustic® panels are made in the UK to exacting quality standards - and are ready for immediate installation. The mineral wool panels incorporate 70% recycled content, with the basecoat 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 have a lambda value of 0.032 W/mK, to provide excellent thermal performance and reduce heat loss through the building envelope. The product meets the requirements under Part L Thermal Building Regulations 2010 (England & Wales) and Section 6 (Scotland).
