Sonacoustic:
Approved Sonacoustic installers in Ireland: Acoustic plasterboard for perfect sound clarity.
Sonacoustic is a wall and ceiling acoustic & thermal plaster board. This high-end acoustic finish, suitable for galleries, museums, restaurants, libraries, even houses.
Sonacoustic boasts very high levels of sound absorption and minimal heatloss. Due to the trowelled/sanded plaster finish, the powerful acoustics are invisible. As a result, it is perfect if you just don’t like baffles, fabrics, or panels.
It has the ability to be applied to any shaped substrate, therefore making it particularily useful in bespoke spacial designs, where good speech intelligibility is key. Available in any colour.
This is an artisan acoustic finish and our team have 20 years experience working with this kind of product.
Sonacoustic® Composition:
Sonacoustic acoustic plaster board is constructed in two layers. The substrate is first coated with a mineral wool base with a high density. This provides for thermal/sound insulation and absorption. The thickness can be ajusted according to acoustic requirements.
This mineral wool base is then finished with a Sonaplaster® (about 5mm) (available in any colour), which is sanded to a smooth finish.
Acoustic Control
With a mineral wool base beneath the smooth finish, Sonacoustic offers very high sound absorption coefficients.
Tests have been performed on Sonacoustic in various thicknesses which produces a NRC rating. (Noise reduction coefficient).
