Understanding Acoustic Insulation
At its core, Acoustic Insulation is designed to absorb, dampen, or block sound waves. This technology is not just for recording studios or luxury apartments; it's a practical solution for anyone aiming to minimize noise intrusion or contain sound within a specific area.
The Benefits of Acoustic Insulation
The primary advantage of installing Acoustic Insulation is the significant reduction in both external and internal noise levels. This can lead to:
- Protection from external noise
- Comfort and privacy
- Reduction of sound transmission and vibration passing through building elements
- Applications for both renovation projects and new builds
How much insulation do I need?
Building acoustics focus on sound transmission mainly through the perimeter wall, as well as internal walls, floors and ceilings.
Transmission loss (TL) or Sound Reduction Index (R) express the effectiveness of blocking sound, which is frequency-dependent.
This is expressed in decibels (dB). The higher the loss, the better the insulation works as a barrier to unwanted noise.
The amount of acoustic insulation roll, slabs, granulates or panels required will depend on the material you choose, the size of the area being insulated and how much direct, flanking and other sound transmission there is.
