Thermal vs Acoustic Insulation

Thermal insulation creates a barrier that’s key purpose is to reduce heat transfer but, since you’re adding an extra layer to your building, the product does also have sound insulating benefits. Similarly, acoustic insulation creates a sound barrier but it also has thermal benefits.

The key differences between acoustic and thermal insulation to note are:

  • The thicker the insulation, the higher the thermal properties
  • The denser the insulation, the higher the acoustic properties
  • Thermal insulation is rated by R-value
  • Acoustic insulation is rated by density in kilograms

There are some insulation products, such as Ecolife Solutions’ recommended Earthwool® HD insulation, that are sufficiently thick and dense enough to be multipurpose with effective thermal and acoustic properties. These high density insulations are the ideal choice for maximum comfort.

What density do you need?

The higher the density in kilograms, the more effective the insulation will be at absorbing sound. If the noise from busy roads, trains, flight paths or pesky neighbours is particularly loud, we recommend choosing the highest density you can afford to create maximum comfort.

With Earthwool’s HD (high density) insulation products, you’ll also gain the added benefit of fantastic thermal performance.
