Acoustic material

Acoustic innovation with
sustainable commitment

At Harmonium®, we have developed an advanced manufacturing process that improves the stability, strength, and acoustic performance of our panels, enhancing the sound experience in any space. Our acoustic panel is made from 100% polyester PET fiber, with a minimum of 75% post-consumer recycled content, reaffirming our commitment to sustainability.

We also incorporate a needle-punch reinforcement technique that:

Thanks to the quality of our low-melting-point PET fiber, the material offers excellent acoustic properties, optimizing sound absorption.

At Harmonium®, we have developed an innovative manufacturing process to enhance the stability and durability of our acoustic material and improve the sound experience. As part of this advancement, we created the Recycled PET Acoustic Panel, a material made of 100% polyester fiber with at least 70% post-consumer recycled content, reaffirming our commitment to sustainability. We have also implemented a structural reinforcement process using a needle-punching technique.

This stitching not only improves panel stability, preventing deformation over time, but also increases bending resistance, allowing for safer and longer-lasting installation. Thanks to the quality of our low-melting-point PET fiber, the material provides excellent acoustic properties, helping to improve sound absorption in various spaces. Functionality above all.

Frequently Asked
Questions

What are Harmonium products used for?

Our panels are designed for acoustic conditioning and interior decoration. They are ideal for reducing echo and improving sound quality in spaces such as offices, classrooms, restaurants, homes, or shops. Important: they do not soundproof, but improve interior acoustics.

They are made of 100% polyester (PET) fibers, with 75% post-consumer recycled material. This includes plastic bottles that are transformed into a technical, sustainable, and decorative product.

Yes. We use high-density polyester felt, which guarantees dimensional stability, resistance to use, and long lifespan, without deformations or loss of acoustic properties.

Our panels reach very high levels of acoustic absorption (up to aw 0.80 depending on installation). In simple terms: they effectively reduce echo and improve speech intelligibility.

– RAW format: 1225 x 2800 mm – Flawless format: 1205 x 2780 mm – Standard thickness: 12 mm

– Formato Flawless: 1205 x 2780 mm

– Grosor estándar: 12 mm

We offer a wide color range with more than 24 shades, including solid tones.

Very little. They are easily cleaned with a dry or slightly damp cloth, air compressor, vacuum cleaner, or medium-bristle brush. They do not generate dust or release fibers. Check our instructions for proper maintenance.

¿Ofrecéis servicio de instalación?
