Scope
- Impact sound insulation of floorboards.
- Self-adhesive anti-resonant strip for the improvement of the plasterboard structure.
- Anti-resonant strip for metal structures on tiled roofs.
Advantages & Benefits
- Acoustic insulation DnTA>50 dBA.
- By shifting the frequency of coincidence, the lack of privacy that occurs due to the loss of insulation at the previous frequencies (where the human ear is most sensitive) decreases.
- Easy and quick to install.
- High resistance to tearing.
- Improvement of airborne sound level between rigid elements ΔRA>3 dBA.
- Improves the sound insulation of partition walls or wall linings in single-panel systems by minimising the hollow sound.
