SPONGE CAKE Plain Acoustic Wallpaper - 90% Wool

Acoustic wallpaper is a sound-absorbing decorative wall covering designed to reduce echo and improve acoustic comfort in interior spaces. Made from high-density wool felt, this material helps absorb mid and high-frequency sound waves, making it ideal for use in homes, offices, and commercial interiors. Unlike bulky panels, wool acoustic wallpaper offers a seamless look and is perfect for enhancing both design and acoustics in modern interiors.

Installation is simple and does not require special tools. Apply the recommended Fluffo adhesive directly to the wall using a roller or brush - do not apply glue to the wallpaper itself. Join the panels edge to edge (not overlapping), as the thickness makes overlapping unsuitable. Thanks to the wallpaper’s stabilizing paper backing, it can be gently stretched during installation without deforming or tearing. For best results, use a wallpaper brush to smooth out seams and reduce joint visibility.

We recommend using WallFix Adhesive, specially designed for acoustic wallpapers products. This strong, solvent-free adhesive is applied only to the wall surface and ensures proper bonding with wool felt. It is suitable for clean, dry, and primed walls including plasterboard and painted surfaces. Avoid using standard wallpaper glues, which may not provide sufficient adhesion due to the thickness and texture of the felt material.

Yes, wool acoustic wallpaper is safe for indoor use and meets strict European safety standards. It is classified as B-s1, d0 under the EN 13501-1 fire resistance standard — meaning it is flame-retardant, produces very limited smoke, and does not emit flaming droplets. These properties make it suitable for residential, office, and commercial environments where fire safety is a priority. Additionally, wool is a natural material that is low in VOCs (volatile organic compounds), making it a healthy choice for interiors with high air quality requirements.

Wool felt acoustic wallpaper is designed to absorb sound, especially in the mid and high frequencies. While it doesn’t completely block noise like heavy acoustic panels, it significantly reduces echo and enhances speech clarity, making it ideal for open-plan interiors, meeting rooms, or living spaces. The thickness of the wallpaper (approx. 5–6 mm) helps soften hard surfaces without compromising on style.

To clean wool acoustic wallpaper, gently vacuum the surface using a soft brush attachment or textile nozzle. You can also use a dry, soft brush to remove dust. Do not wash, scrub, or use wet cloths, steam, or chemical cleaners, as they can damage the wool surface. For long-term durability, avoid installing in areas prone to frequent dirt, grease, or moisture exposure.
