Sound absorption for walls - PES wall

Wall Sound Absorption – PES Wall for Better Acoustics and Increased Comfort

SilentDirect PES Wall is an effective wall absorber designed to reduce reverberation, echo, and disruptive sound reflections in all types of indoor environments. By installing sound absorbers on walls, sound waves are captured before they have a chance to bounce off the room’s hard surfaces, creating a quieter, more pleasant, and functional acoustic environment. The product is equally suitable for offices, schools, conference rooms, and restaurants, as well as home offices, living rooms, studios, and public spaces where acoustics need improvement.

SilentDirect PES Wall is available in both a Basic version with a visible white polyester surface and a fabric-covered version with removable fabric covers. The fabric-covered models are available in white, gray, black, blue, beige, red, turquoise, green, light gray, and brown, making it easy to match the sound absorber to the room’s interior design and visual aesthetic. All versions are built around the same high-performance core of needle-punched polyester with a thickness of 50 mm.

Effective sound absorption in multiple sizes

The 50mm-thick core of compact polyester is designed to absorb sound energy across a wide frequency range. This reduces reverberation and sound reflections while improving speech intelligibility and making the sound level feel more comfortable. The result is an acoustic improvement that is immediately noticeable in both small and large rooms.

SilentDirect PES Wall is available in sizes 592x592mm, 800x800mm, 1000x1000mm, 1200x600mm, and 1200x900mm. The various formats make it possible to create both discreet installations and larger, cohesive acoustic solutions tailored to the room’s size and needs.

Improved acoustics in all types of environments

Wall surfaces are often one of the main causes of reverberation and disruptive sound reflections in a room. By placing sound absorbers on the walls, sound energy can be captured and reduced before it spreads further into the room. This creates significantly improved acoustics and reduces the acoustic stress that often arises in environments with hard materials such as glass, concrete, drywall, and wood.

In offices and conference rooms, PES Wall contributes to better concentration and clearer conversations. In schools and educational settings, it improves the study environment while making the teacher’s voice clearer. Restaurants, hotels, and public spaces achieve a more comfortable sound level where guests and visitors can converse without having to raise their voices.

In home environments, PES Wall is often used in living rooms, home offices, bedrooms, music rooms, and home theaters where reverberation and echoes need to be reduced. The product is also valued in studios, podcast rooms, and creative environments where a more controlled soundscape is important.

Choose between the basic or fabric-covered version

The white Basic version features a visible surface of needle-punched polyester, creating a clean, modern, and functional look. This design is particularly popular in schools, industrial settings, technical rooms, warehouses, and other environments where functionality and durability are key.

The fabric-covered versions give the absorber a softer and more exclusive look. The removable fabric cover is available in several colors and makes it possible to create an acoustic solution that harmonizes with the rest of the interior. For this reason, the fabric-covered models are particularly popular in offices, hotels, restaurants, meeting rooms, and private homes where design is an important part of the overall impression.

OEKO-TEX-certified acoustic fabric – removable and washable

The fabric-covered models are upholstered with a durable, OEKO-TEX-certified acoustic fabric that combines high durability with a soft and elegant look. The fabric is removable and can be washed at up to 40°C using a gentle cycle in the machine or by hand. It must not be bleached, tumble-dried, or mangled, but can be ironed at a low temperature up to 110°C and is also approved for dry cleaning.

The fabric is designed to allow sound waves to pass through to the absorber’s core without compromising sound absorption. This means that acoustic performance is maintained while the absorber takes on a more exclusive and interior-friendly appearance.

Hypoallergenic, safe, and sustainable construction

SilentDirect PES Wall is made from at least 50% recycled polyester and is free from irritating fibers, strong odors, and harmful substances. The material emits no emissions and is safe to use in sensitive environments such as schools, healthcare facilities, offices, and homes.

The product is also resistant to moisture and mold, allowing it to retain its properties even in environments with varying humidity levels. The robust construction ensures a long service life while requiring minimal maintenance.

Multiple installation options

SilentDirect PES Wall can be ordered with several different installation solutions depending on wall type, aesthetic preferences, and acoustic requirements.

Without mounting accessories
This option provides complete freedom to use your own mounting method, such as adhesive, screws, or another solution tailored to the wall’s construction.

With mounting brackets
When installing with mounting brackets, 4 mounting brackets are included with each sound absorber. Choose between mounting brackets – 0mm spacing for wall-hugging installation or mounting brackets – 50mm spacing, which creates an approximately 50mm air gap between the wall and the sound absorber. The air gap contributes to improved sound absorption.

With concealed mounting brackets
The sound absorber can also be supplied with CNC-milled keyhole brackets in MDF that are permanently glued to the back with 100% solid, solvent-free adhesive. The number of brackets is adapted to the panel’s size and provides a stable and discreet installation without visible hardware.

What is the difference between mounting brackets – 0mm thickness and mounting brackets – 50mm spacing?

The choice between mounting brackets – 0mm depth and mounting brackets – 50mm spacing is about balancing aesthetics and acoustic performance.

Mounting brackets – 0mm clearance mount the absorber directly against the wall and protrude approximately 50mm, creating a sleek and discreet look.

Mounting brackets – 50mm spacing extend an additional approximately 50mm and create an air gap between the wall and the sound absorber. The total projection is then approximately 100mm, which further improves sound absorption, especially in rooms with significant wall reflections.

In summary, mounting brackets – 50mm spacing provide the best acoustic performance, while mounting brackets – 0mm spacing are the best choice when a more wall-hugging and discreet installation is prioritized.

An eco-friendly choice with a long lifespan

SilentDirect PES Wall is designed to deliver high sound absorption for many years. The combination of recycled materials, robust construction, and resistance to moisture and microbial growth makes the product a long-term investment in both acoustics and indoor environment.

Whether you choose the Basic version or one of the fabric-covered models, you get a professional sound absorber that combines effective sound damping, flexible design, and easy installation in a single solution.
