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 adjusted 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.
