Open Cell Acoustic Foam - Sound Absorption Sheets

Buy open cell acoustic foam at Sound Proofing Shop. Open-cell foam is specifically designed to trap and absorb sound waves, making it an effective material for reducing high-frequency noise, echo and reverberation inside your vehicle.

Why Open Cell Foam?

• Absorbs sound waves — the open-cell structure traps sound energy rather than reflecting it
• Lightweight — won't add significant weight to your vehicle
• Flexible & conformable — fits curved and irregular surfaces
• Self-adhesive — peel, stick and you're done

Choose from open-cell foam sheets and acoustic felt in 8mm to 50mm thicknesses, available as individual sheets or in bulk packs for full vehicle builds.

Perfect for campervan conversions, hi-fi installations, engine bays and any application where sound absorption is needed.

Open-cell foam absorbs sound and closed-cell foam blocks it, so many builds use the two materials together.
