The sound-insulating system consists of the eco-friendly acoustic mortar for indoor comfort, based on cork, which is sound-absorbing and breathable, with excellent sound absorption capabilities, called Diathonite Acoustix. It is formulated out of cork, clay, natural hydraulic lime NHL 5, diatomaceous powders, and hydraulic binder. The plaster eliminates reverberation and reduces reflected noise. In addition, the product has high breathability and good thermal insulation characteristics. For smooth surfaces such as existing plasters or concrete, the use of Aquabond, a ready-to-use adhesion primer, is required.

The sound-absorbing plaster is then smoothed with Argacem HP, a highly breathable finishing skim coat in powder form based on hydrated lime, natural fillers, and pure mineral inerts of limestone origin. It can be sponged for a smooth finish. The system is then finished with Decork Design decorative paint for indoor applications, after priming with D20, a water-based acrylic resin bonding agent.
