SONODAN PLUS Autoadhesivo
Multilayer board to provide asymmetry of air noise at low frequencies.
Self-adhesive multilayer board (acoustic membrane + PE + mineral wool) for airborne sound insulation at low frequencies.
SONODAN PLUS Autoadhesivo
SONODAN PLUS Autoadhesivo is a multilayer product that is divided into two different layers. This differentiation allows the counterbalance during the installation, reducing the risk of lack of sealing.
The first layer is formed by a cross-linked polyethylene and a high-density bituminous sheet finished in a self-adhesive film with non-stick plastic. The second layer is formed by a high-density bituminous sheet finished in a self-adhesive film and an absorbent panel of ROCKWOOL.
It is used for sound insulation of music venues in tertiary buildings or located on the ground floor of residential buildings, sound insulation of machine rooms in residential buildings, and renovation of walls between different users.
How it works
The combination of membranes forms a resonator that attenuates low frequencies (a membrane resonator on elastic material — anti-impact), while the mineral wool attenuates medium and high frequencies.
Airborne sound insulation
Airborne sound insulation in music venues DnTA > 70 dBA.
Low-frequency resonator
The membrane junction forms a resonator that attenuates low frequencies.
Mineral wool
Mineral wool attenuates medium and high frequencies.
Self-adhesive
As the membranes are self-adhesive, the second layer is easy to apply.
Low thickness
Low thickness with high acoustic performance.
Flexibility
High flexibility allows for continuity of insulation in difficult encounters.
