Buying thick felt: what you need to know about thickness and acoustics

When purchasing thick felt, there is more to consider than just the colour and finish. Especially if you are using felt for acoustic purposes, thickness plays an important role. Read here everything you need to know about thick felt, which thicknesses are available, and how to make the right choice for your application.

Why choose thick felt?

Felt is not only a decorative material, but it also offers excellent acoustic properties. PET felt is often used to absorb sound in spaces where echoes or reverberation are an issue. The thicker the felt, the better the acoustic performance. This is because thicker felt can capture and absorb more sound waves.

Are there different thicknesses of felt?

PET felt is available in various thicknesses, depending on the intended use. For example, EASYfelt offers acoustic felt in:

9 mm: An excellent choice for light acoustic improvements and decoration.
12 mm: Suitable for spaces with more sound issues, such as offices or living rooms.
25 mm: Ideal for maximum sound absorption in demanding spaces, such as meeting rooms or hospitality venues.

This variation gives you the flexibility to choose the right type of felt for your specific situation.

How do you make the right choice?

When choosing thick felt, there are a number of important factors to consider:

Purpose of the felt

Do you primarily want to improve the acoustics? Then opt for a thicker variant, such as the 25 mm. If you mainly use the felt for decoration, then 9 mm is usually sufficient.

The space in which it is used

For small spaces with little reverberation, thinner felt is often sufficient. In large, open spaces with hard surfaces (such as offices or restaurants), thicker felt provides better sound absorption.

Budget and material usage

Thicker felt is often a bit more expensive, but it also offers more functionality. If you are considering a combination of aesthetics and acoustics, then 12 mm is often a good balance.

Aesthetic wishes

Choose a colour and finish that match the atmosphere of your space. Felt is versatile and available in many colours, making it a good fit for your interior design.

How thick should felt be?

The thickness of felt has a direct impact on its acoustic performance. Thinner felt (such as 9 mm) can reduce light echoes, but for noticeable sound absorption, 12 mm or more is often required. In spaces with a lot of sound reflections, such as high ceilings or hard floors, 25 mm thick felt provides the best results.

The required thickness of felt depends on its purpose and the acoustics in the room. If the acoustics are poor, then buying thick felt is the best choice. If the room already has good acoustics and you mainly use the felt for decoration, then the thickness plays a less significant role. In that case, you can focus more on the colour and how the felt fits in with the overall look of the room.
