Why this product
At 3 mm thick, this cork underlay is an effective, exceptionally thin solution for projects where you want to improve sound insulation without raising the floor height.
Especially suitable for apartments, renovations and anywhere footfall noise between floors needs to be reduced.
Technical description
The cork sheet is made from compressed natural cork granules (Agglomerated Cork), which have a unique cellular structure containing microscopic air pockets.
This structure provides:
- Cushioning of shock and vibration
- Reduction of impact (footfall) noise
- Damping of sound transmission through the floor
The cork is highly flexible and returns to its original shape after compression, ensuring stable performance over time.
The material also combines acoustic and thermal properties, and serves as a separating layer between the flooring and the subfloor.
Applications
- Under parquet
- Under floating floors
- Apartments and residential buildings
- Offices and commercial spaces
- Renovations and low-profile installations
- Light vibration damping
