CHATTERBLOCK+® Acoustic Insulation provides a strong sound barrier between walls, midfloor and outside, thanks to wool's remarkable sound dampening qualities and high density of at least 18kg/m3. It is also an excellent thermal insulator.
Terra Lana CHATTERBLOCK+® Acoustic Insulation can be substituted within all GIB noise control systems (including inter-tenancy walls).
- Intertenancy walls and floors
- Residential and commercial buildings
- Absorber behind perforated ceiling systems
- Internal walls between living areas, bedrooms and midfloor.
