What is acoustic felt?
Have you ever been in a restaurant where you had to raise your voice for the waiter to hear you at all? Or in an office where a colleague’s phone conversation turned into the background of the entire floor? Or at home, when you turn on a movie in the evening and, despite the volume, you still feel like the dialogues are “escaping” in the reverberation? Throughout the house you have to spread carpets to somehow improve the quality of conversations?
These are just examples of bad acoustics. An invisible problem that can fatigue more than a misaligned light or an uncomfortable chair.
And this is where acoustic felt enters the scene. A material that at first glance looks like a decorative wall panel, but in practice acts as a silent ally, that is, it absorbs noise, reduces echoes and makes the space calm. Thanks to it, interiors become not only pretty, but above all comfortable to use.
That’s the magic of acoustic felt. But what exactly is acoustic felt and why does it handle noise so well?
For many people, “felt” sounds familiar – it’s associated with a hat, laptop case or mug pad. Meanwhile, acoustic felt is a completely different story. It’s a material that not only decorates, but realistically changes the way you perceive a space.
The easiest way to visualize this is with a simple example. Sounds in a room behave like ping-pong balls – they bounce off the walls and ceiling, return and overlap, creating reverberation. When felt panels are involved, the balls hit the dense, fibrous structure of the material and are absorbed instead of jumping endlessly.
The secret is in the technology. PET felt is made from recycled plastic bottles, and its fibers form a kind of “trap network.” Each fiber traps a sound wave and dissipates its energy within its structure, so noise is effectively dampened.
How does it work in practice?
The paneled ceiling catches the waves that tend to come back from above and create an echo. The side walls stop acting as a mirror. Panels installed with distance from the wall also absorb lower tones, such as the rumble of footsteps in the hallway or bass from the home theater.
The effect can be heard immediately:
- In the office, phones stop disturbing people at neighboring desks,
- In the conference room, every sentence is clear, without raising the voice,
- At home, the movie sounds like a theater, and the volume remote can finally rest,
- In a museum or art gallery, silence becomes a natural background to focus on the exhibits.
So we can say that acoustic felt organizes sound. From chaos it makes harmony, and from reverberation: a friendly, quiet space.

Applications of acoustic felt
Felt acoustic panels are a solution that you can use in many types of spaces. They are most commonly found in:
- living room and home theater – improve the reception of movies and music,
- Children’s room – they dampen play and noise,
- bedrooms – increase sleeping comfort and privacy,
- Open-plan offices – reduce the noise of conversations and telephones,
- Conference rooms, schools, lecture halls – improve speech intelligibility,
- Restaurants and hotels – they eliminate reverberation and build a pleasant atmosphere.
Ecology and safety – arguments that make a difference
Today’s architecture does not stop with aesthetics. Increasingly, customers are asking about the environmental impact of materials and the safety of users. Acoustic felt made of PET is an example of a solution that meets these requirements 100%.
Ecology – the second life of PET bottles
Each Feltdecor panel is created from recycled plastic. This means that bottles that would normally go to the landfill are turned into aesthetically pleasing and functional interior elements. In commercial and bidding projects, this is a huge advantage – you can clearly tell the client: “This product is not just a design, but a real contribution to the closed loop economy.”
Safety and health
PET felt is hypoallergenic and safe for everyday use – it does not dust, does not emit toxic substances, and does not irritate the skin or respiratory system. This is important both in office spaces and in schools and kindergartens.
Fire resistance – a requirement of public spaces
Feltdecor panels have a fire rating of B-s1,d0 (flame-retardant material with very limited smoke release and no flaming droplets).
In practice, this means that in the event of a fire, the panels do not spread fire and emit minimal smoke, making them safe for use in public spaces. For an architect, this is a ready argument in a conversation with an investor – a safe and compliant product, approved for public spaces. Which can be used without fear in offices, hotels, restaurants or public facilities.
Durability – an investment for years
Unlike acoustic foams, which yellow and crumble after a few years, PET felt retains its appearance and properties for more than 10-15 years. It does not require frequent replacement or expensive maintenance. This means that the project not only looks good at the time of commissioning, but also maintains its quality for a long time.
Therefore, acoustic felt is not a fad, but a material that responds to the real challenges of modern architecture.
PET felt vs. other materials – which to choose?
There are several popular acoustic solutions on the market. Therefore, customers often ask us: “Why should I choose PET felt when there are cheaper options?”. Here is a brief comparison in practical terms to help you choose:
Acoustic foam 
Foam is the cheapest and simplest solution. Lightweight, readily available, it is often found in recording studios or garages converted into rehearsal rooms. The problem is that it ages quickly: it turns yellow, crumbles, and on top of that it doesn’t meet fire safety standards. The acoustic effect is there, but the aesthetics and durability are rather lacking.
Mineral wool
And here comes PET felt – a material that combines technology, aesthetics and durability. At first glance it looks like an elegant wall fabric, but its properties go far beyond decoration. PET felt is made from recycled plastic bottles, making it the answer to today’s environmental challenges.
It is safe (fire class B-s1,d0), color stable and easy to maintain – it will not dust, fade or yellow over time. A simple vacuum cleaner or a damp cloth is enough to restore its perfect appearance.
Although its initial price is higher than that of acoustic foam, its durability of more than 10-15 years makes it a far more cost-effective solution in the long run.
Why choose Feltdecor acoustic felt?
Acoustic felt is a material that combines functionality with design. Architects and designers value it not only for its effectiveness in reducing noise, but also for the fact that it fits naturally into a variety of interior styles – from minimalist offices to modern restaurants.
An informed choice
Feltdecor panels are made from recycled PET material. This means that by improving acoustics, you support sustainable design and reduce the amount of waste going to landfills.
Aesthetics and form
These are not technical mats that need to be hidden. Panels from the TileFlex or TileScratch collections create geometric compositions, decorative textures and an interesting play of light and shadow. In this way, acoustics become part of the aesthetics of the interior, not just a hidden technical element.
Comfort and safety
The PET felt used in the panels has a fire rating of B-s1,d0 (a flame-retardant material with minimal smoke release and no flaming droplets). In practice, this means that the panels are safe for use – both in offices and in hotels or public spaces.
Durability and everyday comfort
PET felt does not lose color, does not deform and retains its acoustic properties for many years.
It requires no maintenance or replacement, and literally takes a moment to clean. It’s a solution that maintains the quality of your project over time, without additional cost or labor.
PET felt is an investment in comfort, aesthetics and durability.
It works well wherever quiet, style and longevity are important – from home living rooms to modern offices.
Types of PET felt panels.
Acoustic panels made of PET felt are not technical contraptions that need to be hidden somewhere, but full-fledged elements of interior design. Thanks to their aesthetics and form, they can become a subtle background of an arrangement or its distinctive accent.
In the hands of an architect and designer, they gain a whole new dimension – they allow to combine acoustic function with aesthetics, creating spaces that are both beautiful and pleasing to look at.
Each Feltdecor collection has its own individual character and different application possibilities. Choosing the right model depends on what effect you want to achieve in your project – whether you want a minimalist geometry, a decorative structure or a solution that discreetly blends into the background.
TileFlex – geometry and simplicity of installation 
TileFlex are 600 × 600 mm square modules that can be arranged in various patterns. Thanks to adhesive mounting, installation is quick and requires no additional construction. This solution will be especially appreciated by designers working in offices that need a quick and aesthetically pleasing improvement of acoustics, in conference rooms where speech intelligibility matters, and in apartments – behind the TV, in the bedroom or in the children’s room.
SilentScape – silence under the ceiling
SilentScape is a system of suspended islands and baffles. Mounted on the ceiling – that is, where sound waves reflect most intensely – they act as an acoustic shield. In open spaces they reduce the noise of conversations and telephones, in restaurants they introduce an atmosphere of tranquility, and in hotel lobbies or performance spaces they allow to control the difficult acoustics of large, high volumes.
TileScratch – acoustics meets art
TileScratch is a collection created for those who expect more from panels than just acoustic function. It is a combination of technology and artistic form – the panels not only absorb sound, but also decorate the space in a unique way.
Delicate linocut-inspired patterns create a subtle depth effect, while the play of light and shadow gives the wall a sculptural feel.
This is an ideal choice for hotel lobbies, elegant restaurants or meeting rooms, where atmosphere, aesthetics and first impressions matter.
PET felt is a material that allows you to design interiors that are beautiful and functional at the same time. It is a way to make the design work not only visually, but also acoustically. It is ecological, safe and durable, while giving the architect freedom of choice – from simple modules to artistic panels. With it, reverberation ceases to be a problem and the design really starts to work: less noise, more peace and comfort.
