Sound absorption for walls – PES Wall

SilentDirect PES Wall – Wall mounted sound absorber with effective acoustic performance and sleek design

SilentDirect PES Wall is a powerful and stylish wall-mounted sound absorber that improves the acoustic environment in all types of indoor spaces. With its clean white surface, dimensionally stable construction, and superior sound absorption, it is the obvious choice for both public spaces and private rooms where acoustics and aesthetics go hand in hand.

Effective sound absorption for various environments

SilentDirect PES Wall is specifically developed to reduce reverberation and unwanted noise by effectively absorbing sound waves reflected off wall surfaces. The product is 50mm thick and made of needlefelt polyester with high density, which provides a high level of sound absorption even at low frequencies. Whether you need to improve acoustics in an open office landscape, a classroom, a conference room, a studio, or a bedroom, PES Wall creates a calmer and more focused environment. It is also well-suited for industrial spaces where noise from machinery needs to be reduced to create a safer work environment.

Allergy-friendly and safe for sensitive environments

SilentDirect PES Wall is made from OEKO-TEX® certified polyester and contains no allergenic substances or harmful emissions. The product emits no odors or irritating particles, making it ideal for use in sensitive environments such as schools, medical centers, offices, or children’s rooms. The material is also resistant to moisture and mold, making it stable and durable even in humid indoor conditions. The compact needlefelt surface is easy to clean and requires minimal maintenance – a feature that makes PES Wall particularly practical in areas with high hygiene standards and long service life requirements.

Stylish design that blends in

With its clean white color and subtle textile texture, PES Wall fits seamlessly into both modern and traditional interiors. The surface has a slightly mottled textile feel and a straight-cut edge profile, allowing panels to be mounted individually or in groups to create a stylish visual impact. The product is available in three sizes – 592x592mm, 1200x600mm, and 1200x900mm – offering great flexibility for both small wall areas and larger installations. You can combine different sizes to create custom patterns or solutions tailored to the room’s acoustic needs and visual design.

Easy installation – ready to use immediately

On the back of PES Wall are CNC-milled keyhole mounts that make installation both discreet and secure. Each sound absorber in sizes 1200x600mm and 1200x900mm is equipped with up to six mounts, while the 592x592mm model has two. The mounts are attached with an eco-friendly, solvent-free adhesive for long-lasting durability – without compromising safety.

This smart mounting system allows you to hang the absorber with just one screw if sufficient for the environment, but also enables multiple attachment points if needed. Thanks to its thoughtful design, no visible screws or framing are needed, resulting in a clean and professional look. The absorbers can be mounted vertically or horizontally, depending on your desired visual expression.

An environmentally friendly choice with long lifespan

SilentDirect PES Wall is made from at least 50% recycled polyester, where recycled PET bottles are given new life as a high-performance acoustic solution. The material can in turn be recycled, making the product a circular and sustainable option for environmentally conscious consumers and projects. Its robust, dimensionally stable structure ensures that the product retains its function and appearance over time, even with long-term use in public spaces. It is unaffected by humidity and has natural resistance to microbial growth, further reinforcing its longevity.
