Sound absorption for walls - PES wall, second-grade

SilentDirect PES Wall – wall-mounted sound absorber with effective sound absorption and flexible installation

NOTE! Second-grade – Same sound absorption, minor cosmetic flaws

Our second-grade products maintain the same high sound-absorbing properties as our standard products, but do not meet our strict requirements for appearance, shape, or dimensions.

Possible deviations may include:

Appearance
Color variations, minor dirt, or superficial marks.

Shape and size
Small indentations, uneven cuts, edge damage, or dimensional deviations outside our standard tolerance of ±1 mm to ±3 mm.

These variations affect only the aesthetics—sound absorption remains as effective as ever. An affordable option for those who prioritize function over appearance!

SilentDirect PES Wall is a modern and powerful wall absorber that improves the acoustic environment in all types of indoor spaces. With its dimensionally stable construction, high sound absorption capacity, and sleek, fabric-free design, it is an obvious choice in both public spaces and private homes where aesthetics and acoustics need to work together. The product is available in three colors—white, gray, and black—and can be ordered with several different mounting options, making it flexible and easy to adapt to various needs.

Effective sound absorption for various environments

With a thickness of 50 mm and a core of high-density needle-punched polyester, SilentDirect PES Wall effectively reduces reverberation and sound reflections from wall surfaces. It contributes to a quieter and more controlled acoustic environment in open-plan offices, classrooms, and conference rooms, but works just as well in studios, bedrooms, stairwells, and industrial environments. The result is improved speech intelligibility, increased concentration, and greater comfort.

Hypoallergenic and safe in sensitive environments

SilentDirect PES Wall is made from OEKO-TEX®-certified polyester and is free from allergens, emissions, and strong odors. It is therefore safe to use in sensitive environments such as schools, healthcare facilities, offices, and children’s rooms. The material is also moisture- and mold-resistant, ensuring the absorbent retains its properties even in high-humidity environments.

Since PES Wall is impervious to water, it is also suitable for more demanding spaces such as swimming pools, restaurant kitchens, and other facilities where regular cleaning and high hygiene standards are part of daily life. The needle-punched surface is easy to keep clean and requires minimal maintenance.

Stylish design in multiple formats and colors

With its discreet textile surface and straight-cut edge profile, SilentDirect PES Wall fits into both modern and classic interiors. The panels can be installed individually or in groups to create continuous acoustic solutions on walls. The product is available in five sizes: 592x592mm, 800x800mm, 1000x1000mm, 1200x600mm, and 1200x900mm, offering great flexibility when planning both small and large spaces.

The combination of multiple formats and three color options makes it easy to adapt the solution to the room’s architecture, function, and visual aesthetic.

Multiple mounting options

SilentDirect PES Wall can be ordered with several different mounting solutions, depending on how and where the sound absorber is to be installed.

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 mounting with mounting brackets, 4 mounting brackets are included with each sound absorber. Choose 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, 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, discreet installation without visible hardware.

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

The choice between mounting brackets – 0 mm and mounting brackets – 50 mm spacing is a matter of balancing aesthetics and acoustic performance.

Mounting brackets – 0mm thickness 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 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 manufactured from at least 50% recycled polyester, using recycled PET bottles as raw material. The product is fully recyclable and designed for a long service life even in high-traffic environments. Its robust construction, combined with resistance to moisture and microbial growth, makes PES Wall a safe and sustainable choice for long-term acoustic solutions.
