Chatterblock+ Acoustic Insulation

CHATTERBLOCK+ Acoustic Interior Insulation

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). 

 

Applications

  • Intertenancy walls and floors
  • Residential and commercial buildings
  • Absorber behind perforated ceiling systems
  • Internal walls between living areas, bedrooms and midfloor.

 

Acoustic test reports

CHATTERBLOCK+® has been assessed for its acoustic performance by Marshall Day Acoustics.

Marshall Day Acoustics generally recommend a flow resistance of 140-200 Rayls or greater, for an acoustic insulation product to be used with double stud or similar wall construction
