A Beginner’s Guide to Insulation – Acoustics

Has spending more time indoors over the past year had you wondering how to soundproof your walls from noisy neighbours?

You’re not alone.

According to TED, noise pollution costs Europe £24Bn every year in lost productivity, health costs and impaired learning!

Building regulations such as Approved Document E specify minimum levels of sound insulation performance for building elements, but going beyond the minimum requirements is important for creating homes, offices, schools and hospitals that are quieter, healthier and more productive.

So how does acoustic insulation work?

Mineral Wool is the best insulation for soundproofing your property, as it is the most effective insulant at reducing sound transmission and reverberations due to its structure.

The fibre matrix of Mineral Wool encourages the absorption of sound waves, converting them into heat energy, whereas other insulation types simply let the sound pass through, which is not ideal if you have noisy neighbours!

Watch our video here to understand how Mineral Wool reduces sound compared to other insulants.

Both Glass and Rock Mineral Wool insulation can be used to achieve the desired acoustic performance, but the right solution depends on your application.

Soundproofing for different applications

Installing sound insulation between floors, such as separating floors, is an effective way to reduce excess noise within a home, as the layer of Glass or Rock Mineral Wool absorbs energy from airborne sound waves coming from above and below the storey.

Mineral Wool is also the best insulation for soundproofing walls, especially internal walls. It works with plasterboard to reduce the sound transmission between dwellings (helping with those noisy neighbours), and can also give an extra benefit of fire protection. All of our Glass and Rock Mineral Wool products are non-combustible.

If you’re not sure which product is best for your application, our Noise Reduction Insulation Product Finder can give you recommendations depending on details such as the location of your project, the application, and the build-up.
