Why Thickness Matters – The 21mm Advantage

Most standard acoustic panels range between 9mm and 15mm in thickness. The 21mm thick Acupanel offers a significantly denser core, which directly improves sound dampening across a broader frequency range – especially low-end noises like traffic rumble, HVAC hum, or bass from speakers. The extra thickness also enhances the physical durability and perceived quality, making panels resistant to warping or denting over time.

Natural Walnut Finish – Timeless Elegance

Walnut wood has long been prized for its rich, chocolate-brown hues and subtle grain variations. These panels showcase real wood veneer over a high-density MDF or PET core, giving you the authentic texture and look of solid walnut at a fraction of the weight and cost. The slatted design (typically 40–50mm between slats) creates a modern linear aesthetic that elongates walls visually, making rooms feel taller and more spacious. It complements both Scandinavian minimalism and industrial loft styles.

Black Acoustic Tissue – Invisible Powerhouse

Behind each slat lies a layer of black acoustic tissue – a non-woven fabric specifically engineered for sound absorption. Unlike exposed foam or fiberglass, this dark backing is almost invisible when viewed from standard angles, but it plays a critical role:

• Traps mid-to-high frequency sounds (voices, keyboard clicks, ambient chatter)
• Prevents sound reflection between the slats and the wall
• Acts as a dust barrier for the inner acoustic felt

The black color also eliminates any “see-through” effect, giving the wall a clean, shadowed depth that enhances the walnut slats’ contrast.
