FAQ

Yes – acoustic panels have been proven to reduce unwanted reverberation and significantly improve room acoustics. Especially in living spaces, offices, or open areas, the felt backing helps absorb sound, making the environment noticeably quieter and more pleasant.

That depends on the size of the room and the desired effect.
As a rule of thumb:

  • 20–30% of wall space → noticeable improvement
  • more surface area → stronger effect

For living spaces, just a few panels are often enough to create a focal point.

Acoustic panels are easy to install - either:

Installation is easy, even without any DIY experience.

Yes, acoustic panels can be custom-cut.
You can:

  • trim them yourself using standard tools
  • or use our cutting service - for a perfect fit with no hassle

Both options are possible:

  • Gluing: fast, clean, ideal for walls
  • Screwing: maximum stability, ideal for ceilings

For ceilings, we recommend a combination of gluing and screwing.

Yes, acoustic panels can also be mounted on the ceiling, where they are particularly effective at improving room acoustics. It is important to secure them properly - ideally with screws or a combination of screws and mounting adhesive.

Several factors play an important role when buying acoustic panels:

  • Finish of the slats
    High-quality panels feature neatly finished and fully wrapped slats for a uniform overall appearance.
  • Material Quality
    A sturdy backing board and dense acoustic felt ensure better durability and noticeable sound absorption.
  • Installation & Customization
    Good panels are easy to install and can be cut to size or customized as needed.
  • Sizes & Variants
    Different dimensions and finishes allow for flexible design in any room.

👉 High-quality acoustic panels thus combine functionality, easy installation, and modern design in a single product.

Absolutely. Especially in offices, conference rooms, or studios, acoustic panels reduce disruptive noise and significantly improve speech intelligibility. 

Acoustic panels are available in various sizes, e.g.:

  • 2600 x 400 mm
  • 2400 x 600 mm
  • 2600 x 600 mm
  • 3000 x 400 mm
  • smaller sizes such as 800 x 400 mm or 400 x 400 mm

This allows them to be flexibly adapted to any wall.

Both.
Acoustic panels combine:

  • functional sound insulation
  • with modern wall design

So they are both a design element and an acoustic solution in one.

Yes, they are ideal for bedrooms.
They provide:

  • less reverberation
  • a calmer atmosphere
  • a more pleasant sense of space

Yes - especially when installed with adhesive, many panels can be removed without leaving any residue (depending on the surface).

Coated slats are coated all around - not just on the front.

Advantages:

  • No visible cut edges
  • Higher-quality appearance
  • Uniform overall appearance

This makes a huge visual difference.
