Reduce Noise with Sound Insulation
To help decide whether or not you need acoustic wall insulation it can help to ask yourself the following questions:
- Which internal rooms would you prioritise first? Typically walls between adjoining bedrooms, bathrooms and laundries are given priority.
- How thick are the wall studs? This will determine the maximum R-value (and also the maximum sound insulation benefit which you can achieve.
- How much will noise transfer really matter? If you live in a home with children, then upgrading to acoustic insulation may be a good idea.
- What about outside noise? Barking dogs, lawn-mowers and even traffic noise – these factors can make a case for installing Earthwool acoustic wall insulation in the outside walls.
The highest R-Value and density achievable with a single layer of insulation in a standard 90mm wall stud is R2.7. These batts are available in widths of 430mm and 580mm to suit typical stud spacings of 450mm and 600mm. Acoustic insulation is rated by density in kilograms per cubic meter, and Earthwool Super HD, with a high density of 27kg/m³, delivers outstanding thermal and acoustic performance—making it a popular choice for TV rooms and home studios.

Not Sheep Wool – Just Super Soft Glasswool!
The entire Earthwool Insulation range, including its sound insulation products, is made from glasswool, primarily composed of natural sand and recycled glass bottles. Thanks to Knauf’s innovative ECOSE® Technology, this next-generation binder eliminates the need for added dyes or harsh chemicals—resulting in a product that is virtually odourless and much softer to touch than traditional glasswool. The insulation’s earthy brown colour and gentle feel might remind you of natural wool, but it’s actually a high-performance glasswool solution, engineered to provide outstanding comfort and efficiency for both homeowners and professional installers.
