Sound absorption for walls - PES wall

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 creates a better sound environment in all types of indoor spaces. With its dimensionally stable construction, high sound absorption capacity, and stylish appearance, 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 – making it easy to integrate into different types of interiors. In addition, it can be ordered with several different mounting options, making it more flexible and adaptable than ever.

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 noise reflected from walls. It works equally well in open-plan offices, classrooms, and conference rooms as it does in studios, bedrooms, or industrial environments. The result is a calmer, more focused, and pleasant atmosphere.

Hypoallergenic and safe in sensitive environments

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 resistant to moisture and mold, which means it retains its properties even in humid indoor environments. As the sound absorbers are completely insensitive to water, they are also suitable for more demanding spaces such as swimming pools, restaurant kitchens, and other premises where high humidity or regular cleaning is part of everyday life. The needle-felted surface is easy to clean and requires minimal maintenance, making the product particularly practical in environments with high hygiene requirements.

Stylish design in three colors

With its fabric-free appearance and discreet textile structure, SilentDirect PES Wall 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 a complete solution. They are available in three sizes – 592x592mm, 1200x600mm and 1200x900mm – and in three colors: white, gray and black. This makes it easy to create an acoustic solution that both meets the functional needs of the room and complements its aesthetic expression.

Multiple mounting options

SilentDirect PES Wall can be ordered with three different mounting solutions – choose the one that best suits your environment and project:

Without mounting hardware – gives you complete freedom to use your own methods, such as glue or screws.

With brackets – choose flat brackets for wall-mounted installation or spacer brackets to create a 50 mm air gap, which improves sound absorption.

With concealed fasteners – CNC-milled keyhole fasteners in MDF, glued to the back with solvent-free glue. The number of fasteners is adapted to the panel size and provides a stable and discreet attachment without visible details.

What is the difference between flush and spacer brackets?

The choice between flush and spacer brackets is a matter of balancing appearance and sound performance.

Dictan brackets – attach the absorber directly to the wall and extend approximately 50 mm. Provides a stylish, discreet result.

Spacer brackets – extend a further 50 mm and create an air gap. The total extension is approximately 100 mm, which improves sound absorption, especially in rooms with clear wall reflections.

Summary – spacer brackets provide the best acoustic performance, while Diktan brackets are the best choice for a more discreet installation.

An environmentally friendly choice with a long service life

SilentDirect PES Wall is made from at least 50% recycled polyester, where PET bottles are reused to create a high-performance acoustic solution. The material can be recycled again, making the product a circular and sustainable option. The robust construction ensures that the absorber retains both its function and appearance over time, even in high-traffic environments. Resistance to moisture and microbial growth further extends its lifespan, making it a safe choice for long-term projects.
