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.

配達予定日にしっかり届きました！　2.5cmを購入しましたが、薄いスポンジみたいな感じでした。開封してから12時間程度放置するだけである程度形が戻ります。急いで戻したい場合の裏技もあります！ドライヤーで当てるとすぐ膨らみます！24時間放置する予定です！
