Fire classification
Fire-rated mesh for hoarding and scaffold — what your specification is asking for
A line on a specification that reads "banner material to be fire retardant" is not a requirement anyone can price or prove. A line that names a standard and a class is. This page sets out what the classifications mean, which ones come up on UAE sites, and what we need from you to answer for your project — because on a hoarding or a scaffold, the certificate is checked at the submittal and again at handover.
What the classifications on your sheet mean
Different consultants write different systems, often on the same project. These are the ones that appear most often on flexible banner and membrane material.
| What it says | The system behind it | What it is measuring |
|---|---|---|
| B1 | DIN 4102-1 (German) | A "low flammability" building-material class. The most commonly quoted line on fit-out and hoarding sheets in this region, often written without naming DIN at all. |
| M1 / M2 | NF P92-507 (French) | A reaction-to-fire classification for flexible materials. M1 is the stricter of the two and is sometimes specified for membranes and tensile fabrics. |
| Class 1 / Class 0 | BS 476 Parts 6 & 7 (British) | Surface spread of flame, and fire propagation. Legacy British wording that still appears on specifications written to older templates. |
| NFPA 701 | NFPA 701 (US) | A flame-propagation test for textiles and films used vertically — the standard most often referenced for banners, drapes and temporary enclosures. |
| Euroclass B-s1,d0 | EN 13501-1 (European) | The current European reaction-to-fire system, with separate ratings for smoke (s) and flaming droplets (d). Increasingly replaces B1 on newer sheets. |
If your sheet says only "fire retardant", ask the consultant which standard and which class. Without that, two suppliers will quote two different materials and both will say they comply.
The certificate matters as much as the material
A material that passes a test is not the same as a material you can prove passed it. What a main contractor actually files is a test report or certificate that names the manufacturer, the product, the standard, the class and a date — and that is traceable to the roll delivered to site. A generic statement on a supplier letterhead is not a certificate, and it is usually rejected at the second review rather than the first. So when a fire classification is in scope, we specify material from a manufacturer that issues that documentation, and we supply the certificate with the submittal rather than after someone asks for it.
What tends to be asked for here
On Abu Dhabi and Dubai sites, temporary enclosure materials — hoarding graphics, scaffold wrap, facade sheeting — are generally expected to carry a recognised reaction-to-fire classification, and the civil defence authority and the main contractor both have a view. The exact requirement is set by the project specification and by the authority having jurisdiction over that site, not by a general rule we could print here. That is why this page explains rather than asserts: the right answer for a villa compound hoarding and for a high-rise facade wrap are not the same, and we would rather read your clause than guess at it.
What to send us for a specified job
Four things, and we can answer precisely instead of generally.
- The specification clause itself — a screenshot of the line is enough
- The application: hoarding, scaffold wrap, facade sheeting or internal
- Which authority or consultant is approving the submittal
- Sizes and quantities, so the material is specified against a real order and not in the abstract
What we will not tell you
We will not tell you that our mesh "is B1" or "is fire rated" as a property of our company. A classification belongs to a specific material from a specific manufacturer, evidenced by a specific certificate — and it is the certificate, not the claim, that gets filed. What we will do is read your clause, specify material that carries the documentation it asks for, and supply that documentation with the pack. If a clause asks for something we cannot source for the quantity or the programme, we will say so while there is still time to change it, rather than at handover.
Questions we are asked
Is your mesh banner fire rated?
That is the wrong question to ask any supplier, and a supplier who answers it with a flat yes should worry you. A classification belongs to a material and is evidenced by a certificate for that material. Send us the clause and we will specify something that meets it and supply the certificate with the submittal.
Our spec just says "fire retardant". Is that enough?
No, and it is worth going back to the consultant. Without a named standard and class, two suppliers can quote two completely different materials and both claim compliance — and the difference surfaces when the certificate is reviewed, usually after the banner is already printed.
Does fire classification change the look of the banner?
Not meaningfully. It changes the material you are buying and what it costs, not what the print looks like. What does change is lead time, because a specified material is ordered rather than taken from stock.
Can you supply the certificate with the submittal?
Yes, when the classification is agreed at enquiry. That is the point of asking early: the certificate has to come from the manufacturer of the material actually supplied, so it is decided when the material is specified, not when the submittal is due.
Does the certificate cover the printed banner or just the base material?
The classification is held by the base material. Ask your consultant whether they require evidence covering the printed and finished article, because some specifications do, and that is a different conversation to have before production rather than after.
