EN 13501-1 fire classification
B-s1,d0 level, the standard expected in public buildings. Test report from a notified laboratory, ready for the fire safety commission.

Guarantees, certifications and proven performance.
In a public building, fire compliance is not a marketing claim, it is an obligation that a fire safety commission checks. You may as well turn it into a selling point. Our acoustic panels are rated EN 13501-1 B-s1,d0, absorb up to 85% of sound (NRC 0.85) and are built on a PET felt, part of which is recycled. Every order arrives with its proof: the fire classification test report and the absorption datasheet. Enough to reassure your client, clear a commission and win a tender.
What we guarantee
Three proofs, delivered with every order.
An acoustic promise with no paperwork is worth nothing in front of an inspection body. So we built our offer around enforceable records, not slogans. Three guarantees form the foundation: the fire classification to clear a public building, measured absorption to hit the acoustic target, and a healthy, traceable material on the environmental side.
Why does it matter for selling into public buildings? Because your client isn't buying a panel from you. They are buying the assurance that their project will pass the fire safety commission, that their architect will approve the datasheet, and that their sustainability budget will hold up at audit. If you arrive with the fire classification test report and the absorption datasheet in the same envelope, you cut three objections short at once. Compliance becomes a closing argument rather than a risk to manage.
A brand-new company has to prove, not narrate. All our evidence is verifiable: a fire test comes from a notified laboratory, an absorption value from a measurement report, the recycled origin from a material datasheet. No invented testimonials, no borrowed client logos. Just the specs, the process and the real guarantees. That is what holds up in a commission, and that is what reassures a professional buyer.

The guarantees in detail
Three pillars, three technical pages.
Each guarantee has its own dedicated page, with the standards, the figures and what you need to know to defend a file.
NRC absorption coefficient
NRC 0.85, roughly 85% of noise absorbed across the voice band. Detailed absorption datasheet per frequency.
See the NRC coefficient →
Recycled PET material
Polyester felt, part of which comes from recycled bottles. Healthy, no irritating fibres, high-performing and traceable.

Everything you need for your file.
Four deliverables, every time, so nothing gets blocked on safety, acoustics or purchasing.
Fire classification report
The EN 13501-1 test report, issued by a notified laboratory. The enforceable record for a fire safety commission.
Absorption datasheet
Absorption values per frequency band and the NRC. Enough to prove the acoustic target, figures in hand.
Approved artwork proof
The proof you signed off before production: visual, dimensions, finishes. Zero surprises on delivery.
Delivery tracking
Tracked DDP shipping, duties and taxes included. You know where the order stands and when to schedule installation.
Tip. Flag your public-building constraints from the quote stage: type of establishment, occupancy, classification requirement, tender sustainability criterion. We adapt the documentation up front, rather than discovering a gap when the file is submitted. A round trip in commission costs weeks, a line in the brief costs nothing.
In a public building, fire compliance is not a box to tick. It is the condition to open the project. You may as well make it an argument, evidence in hand.

Frequently asked questions
Guarantees and compliance: your questions.
What documents come with an order of acoustic panels?
Every order arrives with its EN 13501-1 fire classification test report, the material's acoustic absorption datasheet (values per frequency band plus NRC), the artwork proof you approved before production, and delivery tracking. These are the exact records an inspection body, a fire safety commission or an architect will ask for in a public-building file. You receive them digitally, ready to drop into a fire safety file or a tender. Nothing to chase afterwards: compliance is part of the product, not an add-on to tick at the very end.
Is the EN 13501-1 B-s1,d0 classification enough for a public building?
For the vast majority of public-access buildings, yes. The B-s1,d0 level describes a material that is barely combustible (B), produces very little smoke (s1) and no flaming droplets (d0). It is the level expected for wall and ceiling finishes in spaces open to the public. Depending on the type of building and its capacity, the requirement can vary, so we check your case before starting production. The test report, issued by a notified laboratory, is the enforceable proof, not a mere marketing line. That report is what carries weight in front of a commission.
What does an NRC of 0.85 actually mean?
The NRC (Noise Reduction Coefficient) sums up in a single number the share of sound energy a material absorbs across speech frequencies. An NRC of 0.85 means the panel absorbs roughly 85% of the sound that hits it, and reflects back only 15%. A bare concrete wall sits around 0.05. The gap is enormous to the ear. Across the 250 to 4000 Hz band, the range of the human voice, PET felt works at its best, which is exactly where comfort is won. The absorption datasheet we provide breaks down the value per band, not just the average.
Is recycled PET felt as high-performing as a new material?
Yes. PET felt is made from polyester fibres, part of which comes from recycled plastic bottles. Acoustic performance comes from the fibrous structure that traps and dissipates sound energy, not from the origin of the material. A well-densified recycled PET reaches the same absorption values as virgin PET. It is also a healthy material: no mineral wool, so no irritating fibres to handle, and stable over time. You gain the environmental argument in a tender without giving up anything on the technical side or on fire compliance.
Do your guarantees hold up for a public tender?
Yes, and it is a common use case. A tender file calls for evidence: fire classification, quantified acoustic performance, sometimes an environmental section on the materials. Our documents cover these three points with official records, not brochures. We can also adapt the response format to your specifications. Flag your constraints up front (type of building, classification requirement, sustainability criterion) and we build the documentation around them. The idea is that your file goes through without back-and-forth, not that you discover a gap when the bids are submitted.
