Key features

🔷 3D diamond groove surface
The geometric groove pattern increases surface area, breaking up sound waves more effectively than flat panels
🔇 NRC 0.92 rated
High-density option absorbs 92% of sound energy — one of the highest ratings available for foam panels
🔥 Flame retardant (high density)
High-density panels contain flame retardant materials — safe for offices and public spaces
✅ SGS certified
Independently tested and certified to E1 eco-friendly material standards — no formaldehyde, no toxins
📦 Vacuum compressed shipping
Panels arrive vacuum-packed for efficient delivery — they expand back to full size within 24–48 hours
🎁 Free double-sided tape included
Every pack includes tape for immediate installation — or use your own preferred mounting method
✂️ Easy to cut and shape
Trim to fit walls, ceilings, doors, or under rugs — sound performance is not affected
🧒 Safe for children and pets
No odor, no toxicity, no formaldehyde — safe for all household environments

⚠️ Important note about white foam

White foam panels are prone to oxidation and will begin to turn yellow within 3–7 days of unpacking. This is a natural property of white polyurethane foam and does not affect sound performance. If color consistency is important to you, choose one of the other color options.

Perfect for these spaces

Recording studio  |  Home studio  |  Podcast booth  |  Vocal room  |  YouTube / content creation setup  |  Home office  |  Control room  |  Home theater  |  Bedroom  |  Living room  |  Baby room  |  KTV / karaoke room  |  Rehearsal room  |  Church / concert hall  |  Office  |  Pet kennel

Who is this for?

These foam panels are the first choice for anyone who needs measurable, professional-grade sound control. The NRC 0.92 rating on the high-density option makes them suitable for serious studio setups, content creators who need clean audio for YouTube, podcasting, or streaming, office managers treating noisy open-plan spaces, and anyone who wants a proven acoustic solution rather than a decorative panel that makes minimal difference. Custom acoustic design drawings are available on request — contact the store for bespoke solutions.

How to install

Step 1
Unpack and expand
Open the vacuum packaging and leave panels in a ventilated space for 24–48 hours to return to full size. Alternatively soak briefly in water, wring out, and air dry or use a hair dryer.
Step 2
Plan your layout
Arrange panels on the floor first to plan the arrangement. Prioritize the wall directly in front of or behind the sound source.
Step 3
Cut if needed
Trim to fit corners, edges, or around fixtures using a sharp knife or scissors — no impact on performance.
Step 4
Attach to surface
Use the included double-sided tape, your own adhesive strips, or panel pins on walls, ceilings, or doors.

Good to know before ordering

  • Panels are shipped vacuum-compressed — allow 24–48 hours after opening for full expansion
  • White foam will oxidize and turn yellow within 3–7 days — choose another color if this is a concern
  • Medium density does not contain flame retardant materials — choose high density for fire-safe installations
  • High density is SGS certified with NRC 0.92 — the recommended choice for serious acoustic treatment
  • Custom soundproofing design drawings are available — contact the store for details
  • Slight color variation between batches is possible — contact the store if an exact match is needed

ottimo pannello riduce un po' il rumore. ed è ignifugo. solo gli adesivi in dotazione non tengono bene e va utilizzato biadesivo di qualità (consigliato)

Le principe de tremper le pack pour séparer les plaques, puis de les mettre au sèche-linge avant d’y apposer les pastilles adhésives double face, est surprenante mais efficace. Je vais les poser au plafond de la chaufferie. J’espère que l’insonorisation est réelle…

I bought white and black. The two colors look really good together. The contrasting colors are great. This corner is where I work. I need an independent space for solitude. This makes me feel comfortable. After the installation, the noise from next door has been significantly reduced, which has achieved the effect I want.
