SilentDirect PES Wall – sound absorber for walls with effective sound attenuation and flexible installation
SilentDirect PES Wall is a modern and powerful wall absorber that improves the sound environment in all types of indoor spaces. With its dimensionally stable construction, high sound absorption capacity, and stylish, fabric-free design, it is an obvious choice in both public environments 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 different needs.
Effective sound absorption for different 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 calmer and more controlled sound 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 clarity, 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 centers, offices, and children's rooms. The material is also moisture and mold resistant, which means that the absorber retains its properties even in environments with high humidity.
Since PES Wall is insensitive to water, it is also suitable for more demanding spaces such as swimming pools, restaurant kitchens, and other premises where regular cleaning and high hygiene standards are part of everyday life. The needle-felted surface is easy to keep clean and requires minimal maintenance.
Stylish design in several 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 mounted individually or in groups to create coherent acoustic solutions on walls. The product is available in five sizes: 592x592mm, 800x800mm, 1000x1000mm, 1200x600mm and 1200x900mm, which gives you great freedom when planning both small and large surfaces.
The combination of multiple formats and three color options makes it easy to adapt the solution to the room's architecture, function, and visual expression.
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 gives you complete freedom to use your own fastenings, such as glue, screws, or other solutions adapted to the wall construction.
With mounting brackets
When installing with mounting brackets, 4 pcs mounting brackets are included with each sound absorber. Choose mounting brackets – 0 mm thick for wall-to-wall installation or mounting brackets – 50 mm distance, which creates an approximately 50 mm 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, glued to the back with 100% solid, solvent-free adhesive. The number of brackets is adapted to the size of the panel and provides stable, discreet mounting without visible fittings.
What is the difference between mounting brackets – 0 mm thick and mounting brackets – 50 mm distance?
The choice between mounting brackets – 0 mm and mounting brackets – 50 mm distance is about the balance between aesthetics and acoustic performance.
Mounting brackets – 0 mm thick mount the absorber directly to the wall and extend approximately 50 mm, providing a stylish and discreet look.
Mounting brackets – 50 mm distance extend a further approx. 50 mm and create an air gap between the wall and the sound absorber. The total extension is then approx. 100 mm, which improves sound absorption, especially in rooms with clear wall reflections.
In summary, mounting brackets – 50 mm distance provide the best acoustic performance, while mounting brackets – 0 mm distance are the best choice when a more wall-close and discreet installation is prioritized.
An environmentally friendly choice with a long service life
SilentDirect PES Wall is made 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.

Hej Joakim,
Tack för din fråga.
Vi rekommenderar du använder en stickbladsåg för mjukt material,
Vill du ha lite bättre kontroll och rakare snitt är ett blad för mjuka material att föredra.
Men ett vanligt sticksågsblad för trä funkar om snittet inte behöver bli snyggt.
Särskilt när skivan ändå ska täckas efteråt.
Ha en fortsatt bra dag.

Hej Per,
Tack för din fråga.
Om du vill läsa mer om hur man på ett effektivt sätt ljuddämpar med hjälp av ljudabsorbenter hittar du fördjupad information i vår Kunskapsportal – jag länkar till den Här.
Den produkt vi rekommenderar som den mest effektiva lösningen för ljudabsorption är SilentDirect PES.
När det gäller PES-skivorna går de absolut att såga och forma efter dina önskemål, förutsatt att du använder rätt verktyg.
Ett sticksågsblad anpassat för mjuka material fungerar mycket bra för detta ändamål.
Jag länkar ett exempel så att du ser vilken typ som avses Här.
Skillnaden på 0,8 och 0.94 är väldigt stort, men det handlar också mer om egenskaper som storlek och tjocklek på materialet som används,
Pet-skivorna som har värdet 0,8 är bara 9mm tjocka och kommer inte att nå upp till samma ljudabsorbering som PES-skivorna som har en tjocklek på 50mm samt absorberingsvärda av 0,94.
Önskar dig en fortsatt bra dag.
Vänliga hälsningar,
Sebastian
