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 three sizes: 592x592mm, 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 disruptive wall reflections. The needle-felted 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 three sizes: 592x592mm, 1200x600mm, and 1200x900mm.

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

Without mounting hardware – gives you complete freedom to use your own methods, such as gluing or screw mounting directly onto the wall.

With brackets – choose flush brackets for discreet wall mounting, or spacer brackets to create a 50 mm air gap behind the panel, which further improves sound absorption in the room.

With concealed fasteners – CNC-milled keyhole fasteners in MDF, glued with 100% solid and solvent-free adhesive. Provides a stable and completely invisible attachment without visible fittings or holes in the wall.

What is the difference between Diktan brackets and spacer brackets?

Dictan brackets attach the panel directly to the wall and extend approximately 100 mm in total, corresponding to the thickness of the panel. This provides a stylish and discreet impression.

Spacer brackets extend a further 50 mm and create an effective air gap behind the panel. The total extension from the wall is then approximately 150 mm. This solution is recommended when maximum sound absorption is desired, especially in rooms with hard walls or high reverberation.

In summary: Spacer brackets provide the best acoustic performance, while flush brackets are the best choice for a more wall-close and discreet appearance.

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 gives it 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.
