Sound absorption for walls - PES wall Deep Absorb

PES Wall Deep Absorb – wall absorber with extra depth and maximum sound attenuation

PES Wall Deep Absorb is an extra powerful wall-mounted sound absorber with double thickness, designed for environments where traditional panels are not sufficient. By combining two layers of SilentDirect PES Wall into a uniform 100 mm thick absorber, the product offers significantly improved sound absorption in both mid and low frequencies. The result is more controlled and comfortable acoustics – whether in work environments, studios, technical rooms, or private homes.

The panel is available in five sizes: 592x592mm, 800x800mm, 1000x1000mm, 1200x600mm, and 1200x900mm, and in white, gray, and black. The discreet structure and fabric-free surface make it easy to integrate PES Wall Deep Absorb into both modern and classic interiors – as individual panels or larger complete solutions.

Sound absorption for demanding environments

With a thickness of 100 mm, PES Wall Deep Absorb effectively reduces reverberation, echo and disturbing wall reflections. The needle-punched polyester core captures sound waves on first contact and contributes to a calmer, more focused indoor environment. The panel is particularly suitable for open-plan offices, conference rooms, classrooms, studios, bedrooms, or other places where improved sound comfort is crucial for function, well-being, and concentration.

Hygienic, moisture-resistant, and safe

PES Wall Deep Absorb is made from OEKO-TEX®-certified polyester that is free from harmful substances, odors, and emissions. The material is mold-resistant, unaffected by moisture, and completely safe to use even in sensitive environments such as schools, children's rooms, restaurant kitchens, or healthcare facilities. The fabric-free needle-felted surface is durable and easy to clean with a vacuum cleaner or light wiping – without losing its shape, volume or function over time.

Stylish design with flexible mounting options

With its fabric-free appearance and discreet textile structure, PES Wall Deep Absorb fits into both modern and classic interiors. The panels have a straight-cut edge profile and can be mounted individually or in groups to create an effective and harmonious sound environment. Choose from three colors – white, gray, and black – and five sizes: 592x592mm, 800x800mm, 1000x1000mm, 1200x600mm, or 1200x900mm.

PES Wall Deep Absorb can be ordered with several different mounting options to suit different environments and needs:

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 mounting with mounting brackets, 4 pcs mounting brackets are included with each sound absorber. Choose mounting brackets – 0mm thick for wall-mounted installation or mounting brackets – 50mm spacer that 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, 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 a matter of balancing 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.

Sustainability and long service life

PES Wall Deep Absorb is made from recycled polyester and is itself fully recyclable. This makes the product a circular and environmentally friendly alternative. The material is stable, moisture-resistant, and dimensionally stable, which ensures a long service life even in environments with high wear or high humidity. For anyone looking for a durable, hygienic, and sustainable wall absorber with maximum acoustic properties, this is a safe and future-proof choice.
