At Nyquista Acoustic Design, we work with both of these materials every day - we offer Wooden Fiber wood wool panels and the EcoLine series made of PET felt. We understand their potential and specifics, which is why we share objective knowledge so your vision can become a functional reality.

Quick choice: Which material is right for you?

Before we dive into the details, here is a quick comparison to help guide your decision:

Choose wood wool (our Wooden Fiber panels) when your priorities are:

• Natural aesthetics and biophilic design: A warm, organic texture that pairs perfectly with wood, concrete, and greenery.

• Top fire safety: Natural A2-s1,d0 or B-s1,d0 class without chemical additives, crucial in facilities with stricter requirements (schools, hospitals).

• Mechanical durability: Exceptional impact resistance, ideal for high-traffic zones (corridors, gymnasiums).

• Healthy indoor microclimate: Natural ability to regulate room humidity.

Choose PET felt (our EcoLine series) when the following are key for you:

• Unlimited design freedom: A huge color palette, easy cutting into any shape, and creation of 3D forms.

• Lightweight and easy installation: The low panel weight significantly simplifies and speeds up installation, reducing labor costs.

• Maximum acoustic performance: The highest sound absorption coefficients (Class A), especially in the form of lightweight baffles and ceiling clouds.

• Circular-economy-focused sustainability: The material is made from at least 60% recycled content and is itself 100% recyclable.

Comparison of key parameters

Detail showdown: What does this mean for your project?

1. Aesthetics and Design

Wood wool is a tribute to nature. Its irregular, fibrous structure brings depth and authenticity to interiors. At Nyquista, we offer Wooden Fiber panels both in natural shades and painted in any color, allowing you to preserve their organic character while fully matching your project palette.
PET felt, on the other hand, is a blank canvas for your creativity. It enables bold color compositions, precise geometric patterns, or organic, three-dimensional forms. Our EcoLine series leverages this potential, making it possible to realize even the boldest visions – from minimalist panels to complex artistic installations.

2. Acoustic performance

Both materials offer excellent sound absorption (Class A in many configurations), effectively reducing reverberation and improving speech intelligibility. Thanks to its mass and structure, wood wool performs very well across a broad frequency spectrum. PET felt, despite its thinner profile, achieves outstanding results, and its lightness makes it an unmatched material for suspended elements (baffles, clouds), which act on sound from both sides, maximizing efficiency.

3. Fire safety

This is where the key difference lies. Wood wool owes its fire resistance to a mineral binder (cement) that surrounds each fiber. This is an inherent property, not an added one. PET felt, as a polyester material, achieves a high fire reaction class (B-s1,d0) through safe, certified flame-retardant treatments. For most commercial projects, both solutions more than meet standards. However, in facilities with the strictest safety requirements, the natural non-combustibility of wood wool can be the deciding factor.

4. Sustainability: Two paths to sustainable development

By choosing wood wool, you opt for a renewable material sourced from responsibly managed forests, with an exceptionally low carbon footprint. By choosing PET felt, you actively participate in a circular economy, giving plastic waste a second life. Both paths support green building and can help you earn valuable points in LEED or BREEAM certifications.

Summary: A partner in delivering your vision

The final choice between wood wool and PET felt is not about one material being superior to the other, but about matching their unique strengths to your project priorities.

• For a project that should radiate natural warmth, durability, and uncompromising safety, Wooden Fiber panels are the ideal solution.

• If your vision calls for design boldness, color, lightweight form, and sustainable innovation, the best answer is the EcoLine PET felt series.

At Nyquista Acoustic Design, we do more than deliver products. We provide knowledge and experience to help you make an informed choice that perfectly complements your vision.
