Fire class B1, explained.

Putting up a panel is quick. But in a school, office or restaurant that panel has to be provably fire safe. Our PET-felt is fire retardant to class B1, with a certificate.

The problem

What fire class B1 means, and what goes wrong without it.

Building materials are classified by how they behave in a fire. Class B1 means flame retardant: in the early stage of a fire, the material barely contributes to the spread of flames. For wall coverings in public and commercial spaces, that is a requirement.

Schools, childcare, offices and restaurants get the same question during inspections, permits and insurance claims: can you prove what is on your walls? Without a certificate the answer is no, and in the worst case the material has to come down.

That is where many cheap felt panels from DIY stores and marketplaces fall short: they don't publish a fire class. Fine at home, but in practice unusable in a commercial space. Our PET-felt is B1 certified in all 28 colours, and the certificate comes with every quote as standard.

B1applies to the whole Viltr range: walls, hanging panels, tiles and custom work. One certificate for everything we cut.

The solutions

Where the fire class makes the difference.

Schools & childcare

Materials in school and childcare buildings must be provably fire safe. B1 with a certificate makes the choice easy to justify to the board and inspectors.

Offices

Facility managers and insurers ask for documentation. With the B1 certificate, you have it ready.

Restaurants and cafés

For permits and fire safety checks, what hangs on walls and ceilings counts. Certified felt passes the check.

Business, sorted

Certified, documented, sorted.

You don't have to ask for it: the B1 certificate comes with every business quote as standard, together with the material specifications architects and facility managers need.

Frequently asked questions

Fire safety: what you want to know.

Is fire class B1 mandatory?

It depends on the building and its use: for public and commercial spaces, building regulations, municipalities and insurers set requirements for how wall coverings behave in a fire. In practice, provably fire retardant material is the norm there, and without a certificate you can't prove anything.

What exactly does B1 mean?

B1 is a fire class for flame retardant material: it doesn't catch fire easily and barely contributes to the spread of flames in the early stage of a fire. It says nothing about sound absorption; the felt does that on top.

Does the fire class apply to all colours and shapes?

Yes. All 28 colours come from the same B1-certified PET-felt, and our cutting doesn't change the class. Walls, hexagons, tiles and custom work all carry the same certification.

How do I get the certificate?

It comes with every business quote as standard. Already a customer and need it after all? Email hello@viltr.nl and you'll have it the same working day.

My current panels have no fire class. What now?

Panels without a published fire class are a risk in a commercial space during inspections or after damage. Replacing them with certified material is the safe route; we are happy to work out what that costs for your space.
