Design PET felt panels with verified parameters. We calculate reverberation, design the shape and look, and deliver the material for your project.

For architects, developers and companies we prepare an acoustic solution precisely for the given space – shape, colour, size and build-up.
Walls, ceilings, screens and design panels. One material, dozens of options.
Slatted and decorative panels that turn an empty wall into an interior feature.
Flat ceiling solutions for quieter rooms without changing the layout.
Free-standing acoustic partitions for open spaces, receptions and cafés.
Milled patterns, arches and waves – the wall as a work of art.
TheFelt! was born in the Potichu team, who have worked in acoustics and soundproofing for years. We saw that people want quiet, but don't want their space to look like a studio. That's why we combine proven acoustic material with design you'll want on display.
We have worked for: Decathlon, Cisco, Kiwi.com, HB Reavis, YIT, Sygic, Markíza, Kino Lumière, Divadlo Aréna and thousands more.
72 felt shades – from pure white to deep blues and earthy tones. Click a colour to see it on the panel. Always check the real shade on a physical sample.
PET Felt is felt made from recycled plastic bottles. The fibres are needle-punched into a strong, lightweight panel that dampens sound and lasts for years.
PET bottles get a second life instead of ending up in landfill.
Sorted waste is shredded and melted into fibre.
Fibres are bonded in layers into dense acoustic felt.
A precise cut, colour and finished design feature for your interior.




The panel itself is primarily a design feature. When we place an acoustic absorber behind it, it becomes a complete acoustic solution. Behind the brand is the Potichu team of acousticians – we'll design the build-up precisely for your space.
Consult your spaceEnter your room dimensions. The Potichu calculator computes reverberation, checks the standard, suggests the number of panels and plays you the sound before and after treatment.

KitKat slatted panels in a new build – living room, kitchen and bedroom in one tone.



A clean, dry and even surface. Mark the position of the panels.
Mounting adhesive for porous surfaces in strips on the back of the panel.
Press the panel and align it. Maintenance: vacuum or wipe with a damp cloth.
The panels alone have an absorption of approximately αw 0.25, so they are mainly a design feature. With an acoustic absorber behind the panel, absorption rises up to αw 1.00.
Glue them directly to the wall with proven mounting adhesive for porous surfaces.
Yes, the panels are certified in class B-s2, d0 for interior use.
Yes, the panels are strong, light and dimensionally stable, so you can mount them on vertical and horizontal surfaces.
They meet the requirements for low VOC levels and indoor air quality standards.
Tell us what space you're working on. We'll prepare a quote, recommend colours and, if needed, design custom acoustics.
We have been working in acoustics since 2011. Every client is looked after by a professional who will discuss your project with you.
