Le feutre PET est-il inflammable ? Guide de sécurité incendie pour les panneaux acoustiques en feutre de polyester

You want quieter rooms and a warm, soft finish. But you also worry about fire. If the walls are covered in fabric-like panels, will they feed a blaze or help control it? PET felt looks like cloth, so it raises real safety questions. Let’s clear them up.

On its own, polyester PET felt can burn, but modern acoustic PET felt panels are designed to be flame retardant rather than highly flammable. With the right density and additives, many products reach Class A or B fire ratings in tests such as ASTM E84, so they can meet fire safety requirements when correctly installed.

What is PET felt and how is it made?

Feutre PET is a type of polyester felt made from fine fibers of polyéthylène téréphtalate, the same plastique pour animaux de compagnie used in drink bottles. In simple terms, this matériau en feutre is a soft but dense textile sheet created when the fibers are carded, layered, and heat-pressed together. Modern pet felt made for interior projects usually comes as rigid panneau de feutre boards in standard sizes and thicknesses.

Le base material est high-quality polyester fiber, and the raw material is carefully cleaned and prepared before production. In many factories, the sheets are fabriqués à partir de matériaux recyclés PET flakes or fabriqué à partir de matériaux recyclés fibers blended with virgin content to balance cost, color stability, and stiffness.

Le felt is made without weaving or knitting; instead, pressure and heat bond each fibre de polyester into a strong and durable mat. This gives PET felt its mix of softness, form stability, and impact resistance that designers like for wall and ceiling finishes.

As a professional manufacturer in China, we run this process in-house, which lets us control color, density, and thickness for different architectural and acoustic needs.

Is PET felt flammable or fire resistant in real projects?

Like any polymer, PET can catch fire if exposed to enough heat. But dense PET felt used on walls and ceilings is engineered to slow flame spread and improve fire resistance. The fibers melt and shrink away from the flame, and the panel structure tends to char rather than flash up like paper.

In other words, with the right recipe, the material becomes more fire resistant than many decorative fabrics or thin foams used in interiors. Additives and controlled density boost the flame retardancy of the panel, so it does not drip burning material and does not support a high fire growth rate the way some plastics do.

When PET felt is engineered and tested correctly, you can specify it as a fire-resistant finish within the limits of local code, while still keeping the good propriétés acoustiques that make it attractive for noisy rooms. That balance of safety and comfort is exactly what most architects, interior designers, and contractors are looking for.

What makes PET felt fire retardant?

The key is chemistry and structure. During production, the resin is modified into flame-retardant polyester before it becomes fiber. In our own lines, we use carefully selected flame-retardant polyester fibers so the protective behavior is “inside” the fiber, not just sprayed on the surface.

Inside each panel, the dense tangle of fibers creates a complex path for heat and oxygen. This slows burning and keeps the surface more stable. A small amount of retardant additives helps the char layer form quickly, which protects the inner layers and reduces smoke release compared with untreated fabrics.

This combination lets PET felt reach demanding fire classes while still behaving like a soft, workable panel that can be cut, beveled, or CNC-milled into patterns without losing its safety performance.

Which fire ratings and tests do PET felt acoustic panels meet?

Fire performance is not a guess; it is measured. Around the world, PET panneaux acoustiques en fibre de polyester are tested to well-known international standards such as:

• ASTM E84 (U.S. “Tunnel Test” for surface burning characteristics)
• EN 13501 (European fire classification for construction products)
• GB 8624 (China’s burning behavior standard for building materials) 

Quand les panneaux acoustiques sont fabriqués for export markets, manufacturers like us typically test them to at least one of these systems. High-quality PET felt boards often achieve Class A or B under these methods, meaning they resist ignition, limit surface burning, and keep smoke at controlled levels. 

To make life easier for specifiers, many of our products meet ASTM E84 class A, which is widely accepted in schools, offices, and other commercial interiors. 

Here is a simplified comparison for typical 9–12 mm PET felt panels, based on common published data:

What are the benefits of PET felt acoustic panels for acoustics and design?

One of the big benefits of pet felt is how it helps with l'absorption acoustique and overall performance acoustique while still looking clean and modern. By tuning density and thickness, PET felt can reach high NRC (Noise Reduction Coefficient) values. Tests show that 12–25 mm polyester panels can offer excellente absorption du son, especially in the speech range, making meeting rooms, classrooms, and open offices more comfortable. 

When you use matériaux absorbant le son like PET in an traitement acoustique plan, you reduce echoes and lower bruit ambiant. The panels don’t block all noise like heavy concrete; instead, they act as absorbant le son “sponges,” turning sound energy into a tiny amount of heat inside the fiber network. This also adds modest l'isolation acoustique between adjacent spaces when panels are combined with solid backing.

For designers, Panneaux acoustiques en feutre PET are flexible tools:

• They can be cut into baffles, clouds, and wall art.
• Colors and patterns can be customized to match branding.
• Panels can double as pin boards or feature walls.

Because the panels are lightweight, panels are an excellent choice for renovation projects where you want to improve the acoustics of your space sans construction lourde.

Is PET felt safe for schools, offices, and other public spaces?

Most projects we support are public spaces like schools, libraries, offices, and transport hubs. In these environments, safety, durability, and ease of maintenance matter as much as acoustics.

Well-designed PET felt can handle daily wear and tear while staying stable on the wall or ceiling. The finished panel is a durable material that is dent-resistant, cleanable, and reasonably resistant to heat from sunlight or nearby light fixtures. Combined with proper fire tests, this gives specifiers confidence. 

Because the panneaux muraux are tested and certified, they help you meet fire safety codes in many regions when installed according to the manufacturer’s details. At the same time, a felt wall surface creates a warm, quiet feel that people enjoy far more than bare concrete or metal. For busy corridors or open-plan offices, these panels are easy to integrate with lighting, signage, and other interior elements.

PET felt vs traditional felt and other acoustic panel materials

Compared with feutre traditionnel made from wool or mixed fibers, PET felt is more consistent, more dimensionally stable, and easier to fabricate at large sizes. Wool can char nicely in a fire, but it is harder to standardize and more sensitive to humidity and moth damage.

If you compare PET felt to other acoustic panels on the market, you will see that panneaux acoustiques en polyester often sit between soft fabrics and rigid mineral boards. They offer better design freedom than typical fiberglass tiles while avoiding the brittle feel of some hard boards. For feature panneaux de feutre acoustique, baffles, and ceiling rafts, this balance of stiffness and softness is very useful. 

From a product family view, panneaux pour animaux de compagnie come in many matériaux disponibles such as plain sheets, slatted profiles, 3D tiles, and printed surfaces. For distributors and brand owners, this is a chance to build a rich product line using one core technology.

How recycled plastic bottles become PET acoustic panels

A big advantage of PET felt is sustainability. Most boards use a high percentage of plastique recyclé. In many cases, they use PET flakes from bouteilles en plastique that have been sorted and cleaned. These are melted and spun into fibers, then turned into panels. Some products are even fabriqué à partir de bouteilles en plastique recyclées at rates of 60–75%. 

This process supports the recycle economy by turning fabriqué à partir de bouteilles en plastique recyclées waste into long-life building components. It is both écologique et l'environnement responsible, especially when panels can be recycled again at end of life.

For architects and brand owners working on green buildings, PET felt is often promoted as fabriqué à partir de matériaux recyclés content. When combined with low-VOC binders and clean production, this can help contribute to sustainability certifications and client targets.

FAQs about PET felt fire safety and acoustic performance

Is PET felt safe enough for code-regulated projects?

Yes—when you choose tested panels from a reputable manufacturer, PET felt can be used in many code-regulated interiors. In China, high-quality polyester boards typically reach B1 flame-retardant levels under GB 8624, meaning they are not easily ignited and self-extinguish after flame removal, satisfying the fire safety requirements of most indoor projects.

How does PET felt compare to other sound-absorbing materials?

PET felt is one of several matériaux absorbant le son used for traitement acoustique. Compared with mineral wool, it is cleaner to handle and easier to shape. Compared with thin foam, it is more robust and long-lasting. For many designers, PET-based feutre acoustique strikes a good balance between performance, cost, and design freedom.

Can PET felt improve the acoustics of my space on its own?

Yes. When you add enough coverage, especially on hard parallel walls, PET felt helps control echoes and bruit ambiant. Panels installed at key reflection points change the propriétés acoustiques of the room, making speech clearer and reducing fatigue. For many offices and classrooms, this single step makes the room feel calmer and more focused.

Are PET felt wall and ceiling panels easy to install?

Most panneaux de feutre acoustique are designed so that installers can cut them on site and glue or mechanically fix them to substrates. This makes the system fast to fit, even on curved surfaces or complex shapes. For contractors, this is one reason these panneaux muraux and ceilings are popular: they save labor without sacrificing safety.

Does PET felt offer any thermal insulation benefits?

PET felt boards add a small amount of isolation et l'isolation acoustique, because trapped air in the panel slows both heat flow and sound. They do not replace dedicated insulation in the building envelope, but they can boost comfort when combined with other layers in a wall or ceiling build-up.
