Who is this for?

This is the most versatile listing in the range — the combination of three thickness options and four pack sizes means it suits every wall treatment scenario from a single bedroom wall to a complete professional studio build. If you are not sure which thickness to order, 2 inches is the right starting point for almost everyone. If you have a specific problem with bass frequencies or low-mid buildup, go to 3 inches. If you just want a subtle improvement in a living room or office, 1 inch is enough. Order 6 panels to start — most buyers order more once they hear the difference. Custom wall treatment layouts available — contact the store.

How to install on walls

Step 1

Unpack and expand

Open vacuum packaging and leave in a ventilated space for 24–48 hours. Or soak in water, wring out, and blow dry for faster expansion.

Step 2

Start with the worst wall

The wall directly opposite the main sound source generates the most reflected noise — treat this first regardless of the room type.

Step 3

Cut to fit

Use scissors for 1-inch panels. Use a sharp serrated knife for 2-inch and 3-inch panels — cut cleanly around outlets, switches, or wall features.

Step 4

Mount and expand

Use the included tape for walls — removable adhesive is renter-friendly and leaves no damage. For 3-inch panels use stronger adhesive or panel pins.

⚠️ Important note about white foam

White foam panels will oxidize and turn yellow within 3–7 days of unpacking. This does not affect wall soundproofing performance. If color matters on your wall, choose one of the other 7 available colors.

Good to know before ordering

Three thickness options: 1″, 2″, and 3″ — if unsure, choose 2″ as it suits the widest range of wall treatment needs
Available in 6, 12, 24, or 48 panel packs — 48 panels covers 4.32 m² of wall surface
High density (NRC 0.92, SGS certified) is recommended for all wall soundproofing beyond basic decoration
For 3-inch panels use stronger adhesive or panel pins — included tape may not support the extra weight long-term
Panels arrive vacuum-compressed — allow 24–48 hours after opening for full expansion
White foam turns yellow within 3–7 days — choose another color if wall appearance matters
Custom wall treatment layouts available on request — contact the store for details

Better walls. Better sound. Start with 6.

Triangular groove foam — 1″, 2″, or 3″ thick. NRC 0.92. Free tape. 6 to 48 per pack. Ships worldwide.

Виглядає дуже добре, все вийшло) зробила свою домашню студію. Тільки колір не білий, а більш жовтіший, це єдине, що хотіла чисто білий. Але гарно.

Товар приїхав доволі швидко, все ціле. Упакований був доволі щільно, навіть на початку не вірилось, що це 12 плит. Але дома вже по інструкції повторила перший метод, тільки без прання, і вони стали такими як на фото. Все ціле, вижимати від води їх не бійтесь - не рвуться. Дякую

I recommend everyone to buy the high-density style. The quality of the high-density style is indeed better than the medium-density style. I used to feel that the price was too expensive and did not choose the high-density style, so I always bought the medium-density style. But one time I really wanted to try the high-density style, so I bought a set to try it out. After receiving the goods, the quality was really different. Compared with the medium-density style I bought before, the texture and the softness of the sponge are different. Because I am a podcaster, when I changed to the high-density style and placed it next to my microphone, the sound reception effect was obviously better than the medium-density style. I think I will buy high-density styles and continue to use them in the future.

S***e

Me espanté cuando llegaron y vi que no se terminaban de “inflar” después de pasados 2 días, por aquí mismo leí que poniéndoles agua, los introduje en la bañera y tomaron incluso un poco más de los 2.5cms de espesor! Excelente!

Sehr gute absorber für kleine zimmer oder für Studios brauche noch mehr von den Absorbern für die wände top

Po 2 godzinach bez robienia niczego wszystkie już sie rozszerzyły do 4cm i przykleiłem, po 24h wszystkie na ścianie miały już 5cm, polecam

they did come as expected, even though buying the extra trick in the end only has a medium to small size density, they are big enough, and they're not as deep as they show on the pictures, though the product itself is really good and is as promise

Great product ! Come with instructions and is very easy to install

немного тоненькие, но подойдут.

wszystko ok, na drugi dzień po wyjęciu gąbka wróciła do oryginału, bez prania i suszenia. żadna nie była uszkodzona.

These are actually good They look fair and perform just as well as you'd expect them to Might steer away from sticking them directly on my wall, but overall it's a good product Definitely get the high density ones if you can tho

parfait comme je le souhaitais
