Acoustic Wall Coverings, Wall Absorbers

Decorative Textile Wall Coverings for Acoustic Improvement and Thermal Insulation

High-quality acoustic wall coverings improve room acoustics while creating a balanced, comfortable indoor environment. These systems combine sound absorption class A with vapor-permeable thermal insulation, providing acoustic comfort and energy efficiency in a single product.

Whether used as large-area wall coverings or as a targeted solution for individual wall sections, these acoustic panels offer flexible design options. They reduce reverberation, improve speech intelligibility, and also serve as an aesthetic design element. Ideal for offices and living spaces, hospitality venues, schools, public buildings, and creative interior design projects.

Acoustic Panels with Versatile Design Options

The design possibilities for acoustic panels are virtually unlimited. The panels can be color-coordinated, combined in contrasting colors, or deliberately used as a graphic design element. With over 50 available shades, you can create both calm, harmonious surfaces and vibrant wall patterns. Depending on the arrangement and color selection, crisp lines or flowing transitions can be created to shape the room's overall appearance.

In addition to color, surface textures play a key role. Precisely cut V-Cut lines or pressed relief patterns create depth, shadow effects, and a tactile dimension that goes beyond color alone. From orderly geometric grids to organic-looking textures, virtually any design can be achieved. Multiple textures can also be combined within a single wall surface.

Acoustic panels can also be customized with graphic motifs or image-based elements on request. High-resolution CMYK direct printing enables both subtle surface designs and striking visuals, for example for corporate architecture, wayfinding systems, or design accents in public spaces.

Custom Dimensions and Easy Installation

The acoustic panels are precision-manufactured using CNC technology. Standard sizes such as 2400 × 1200 mm or 2800 × 1200 mm are available, as are custom dimensions and panels cut to size for your project. The lightweight, rigid PET felt allows the panels to be installed directly on existing wall surfaces, including plaster, concrete, wallpaper, or drywall. Existing wall coverings generally do not need to be removed.

Adhesive, screw, or rail systems are used for mounting. All elements are supplied ready to install, allowing even large-area installations to be completed quickly and cleanly.

Tiles – Modular Wall Design with a Building-Block System

Tiles offer a particularly flexible solution: manageable acoustic modules measuring 1200 × 600 mm that are easy to ship, easy to install, and visually versatile. Tiles can be manufactured in the same colors and material thicknesses as large-format panels and combined to create custom patterns or continuous surfaces.

Different textures and surface patterns create a versatile building-block system for creative wall design. Colors and textures can be freely mixed to create individual designs. Versions with a nonwoven composite (9 + 40 mm) are available as an option for improved broadband sound absorption.

The combinable structure allows for modular acoustic walls that can be expanded or color-adjusted at any time – ideal for dynamic room layouts and projects with flexible uses.

Acoustic Effects and Applications

Hard wall and floor surfaces reflect sound and cause disruptive reverberation. Wall absorbers reduce this effect by absorbing sound energy and converting it into heat. The result is a noticeably quieter acoustic environment, better speech intelligibility, and a pleasant sound quality. This improves concentration, well-being, and indoor comfort.

Acoustic Performance – Tested to ISO 354 / Rated to DIN EN ISO 11654

The acoustic performance of our PET felt wall coverings has been measured by independent laboratories in accordance with ISO 354 and rated in accordance with DIN EN ISO 11654. The achievable sound absorption class depends on the selected mounting configuration:

• NRC 0.35 | Sound absorption class E – when mounted directly on the wall without an air gap (0 mm)
• NRC 0.85 | Sound absorption class B – when mounted with a 50 mm air gap – extremely absorptive
• Sound absorption class A – with a nonwoven composite (PET + 40 mm nonwoven) – broadband absorption from 250 Hz, even without an air gap

For maximum acoustic performance, we recommend mounting on a supporting framework (furring strips or Z-rail) that creates a uniform air gap of 30–50 mm from the wall. Alternatively, the nonwoven composite (9 mm PET + 40 mm nonwoven) achieves the highest sound absorption class A even when mounted flat directly on the wall.

PET felt acoustic wall coverings support compliance with DIN 18041 for reducing reverberation time, particularly in rooms with demanding speech intelligibility requirements, such as conference rooms, schools, medical offices, and restaurants.

Certifications and Fire Safety

• Flame-resistant in accordance with EN 13501-1 (B-s1,d0) – tested by Intertek, meets DIN 4102 B1
• OekoTex 100 – tested for harmful substances, suitable for kindergartens, schools, and hospitals
• Greenguard Gold – low VOC emissions for healthy indoor air
• EPD (Environmental Product Declaration) – relevant to DGNB and LEED certification
• SCS Recycled Content – certified recycled content from PET bottles

Material, Quality, and Sustainability

The base material consists of PET felt with a high proportion of recycled plastic fibers. The felt is dimensionally stable, low-emitting, flame-resistant (B-s1, d0), and Oeko-Tex® certified. Thermal bonding keeps the material dimensionally stable over the long term, even in large-format applications. An optional nonwoven composite can be laminated to the back to improve both acoustic and thermal properties.

The materials are easy to maintain, UV-resistant, and colorfast. This makes them ideal for long-lasting indoor acoustic solutions, from offices to residential and educational spaces.

A Wide Range of Applications

PET felt acoustic wall coverings are used in virtually every area of interior design:

• Offices and open-plan spaces – reduced reverberation for focused work
• Conference and meeting rooms – improved speech intelligibility for productive meetings
• Schools, daycare centers, and universities – OekoTex-tested and B1-certified for safe learning environments
• Restaurants, hotels, and hospitality venues – a comfortable atmosphere for guest conversations
• Medical offices, hospitals, and therapy rooms – speech privacy and a quiet atmosphere
• Retail interiors and showrooms – acoustic and visual improvements to sales spaces
• Living spaces, hallways, and stairwells – decorative accents with an acoustic function
• Studios, music rooms, and creative studios – targeted sound control for recording and production

In both new construction and renovation projects, acoustic wall coverings offer an efficient, aesthetic solution for improving room acoustics without altering the building structure.

Made-to-Measure Design

All panels can be custom-manufactured. In addition to classic rectangular formats, round, diagonal, or free-form shapes are also possible. Edge treatments with chamfers or miters allow for sculpted transitions or shadow gaps. The result is three-dimensional wall surfaces that blend harmoniously into any architectural concept.
