Can 3D wall panels be EI30? No, and no decorative cladding from any manufacturer can be. EI30 is a fire-resistance class that belongs to a complete wall assembly, not to the finish applied to its face. That is not a gap in the product; it is what the classification means. The question worth answering is the one behind it: can a decorative panel go onto a wall that has to hold a fire rating, and what do you need to check before it does? This page separates the two fire properties specifiers routinely conflate, and sets out where a gypsum panel sits between them.

Can 3D wall panels be EI30?
The direct answer is no, and it is worth understanding why the question cannot be answered any other way. EI30 describes how long a building element goes on doing its job in a fire. It is measured on an assembly: a stud partition with its boards, framing, joints and fixings, or a masonry or concrete wall. A decorative panel adhered to the face of that wall is not the element being classified. Ask any manufacturer of decorative cladding for an EI30 certificate for their panel alone and they will tell you the same thing.
This matters because the two properties are governed by different parts of the same European standard, and the numbers look similar enough to blur. As one firestop engineering guide puts it, resistance to fire is a system-oriented measurement, referring to a construction element, in contrast to the purely material-oriented reaction-to-fire criterion. Once that distinction is clear, the specification question becomes answerable.
Fire resistance vs reaction to fire: two different questions
Reaction to fire asks what a material does when fire reaches it: does it ignite, does it spread flame, does it add fuel. Fire resistance asks how long an assembly holds back a fire that is already burning. A material can score well on one and be irrelevant to the other.
| Reaction to fire | Fire resistance | |
|---|---|---|
| Standard | EN 13501-1 | EN 13501-2 (non-loadbearing walls tested to EN 1364-1) |
| Classes | A1, A2, B, C, D, E, F | E, I and R combinations with minutes, such as EI30 |
| What is classified | the material or product | the complete building element as tested |
| The question it answers | does this add fuel to a fire? | how long does this barrier hold? |
| Kandes gypsum panels | classified A1, non-combustible | not applicable to a panel on its own |
On the reaction-to-fire scale, classes A1 and A1fl are considered non-combustible, and A1 is the most stringent rating the scale offers. That is the class Kandes 3D gypsum wall panels hold: classified A1 (EN 13501-1), non-combustible. Passive fire protection guidance describes what non-combustibility means in practice, namely that at no stage of a fire, even a fully developed one, does the material increase the fire load. The panels are produced in the European Union and classified to that European standard, so the documentation sits inside the framework a European specifier already works in.
What EI30 actually measures
The letters are not decoration. E stands for integrity: the element must keep flames and hot gases from passing through, with no sustained flaming on the unexposed face. I stands for insulation: the element must limit the heat conducted through it, so the far side stays below defined temperature rises. The number is the duration in minutes for which both criteria are held under the standard fire curve. In German practice the same pairing is written literally as E for Raumabschluss and I for Wärmedämmung, classified for Bauteile, building elements.
An EI30 wall, then, is a wall that has been shown to stop fire passing and to keep the unexposed face cool enough for thirty minutes. Fire-glass guidance makes the same split plainly: E provides an effective barrier against smoke and flame, while I addresses heat transfer. Both are properties of a tested build-up, which is why the classification travels with the assembly and not with any layer inside it.
Where an A1 gypsum panel fits on a fire-rated wall
Here is the part that needs stating carefully, because it is where good intentions turn into a claim nobody can stand behind. An EI rating always belongs to the complete wall assembly as it was tested, never to any single material within it, and assemblies containing combustible components can and do achieve fire-resistance ratings. A material's reaction-to-fire class is a separate property. What an A1 material contributes is not the EI rating itself, but the certainty that it adds no fuel to the fire.
So the honest position for a gypsum relief panel from Kandes is this. Because it is classified A1, non-combustible, the cladding adds no fuel and no fire load. In typical build-ups it does not degrade the wall's fire performance. But an EI rating is certified only for the wall system's tested configuration, and the classification report defines the field of application, the scope of allowable changes from what was actually tested. Whether the rated wall retains its classification with the cladding and its fixings attached must be confirmed for the specific project with the wall-system manufacturer or the fire-safety planner.
That is not a formality to be waved through. The things that can affect a rated wall are mostly independent of the panel being non-combustible: fixings that penetrate the fire boards, a batten sub-frame that introduces a cavity, an adhesive that is not itself A1, additional mass on a non-loadbearing stud. None of these are exotic. All of them are ordinary decisions taken on site, which is why they belong in the specification rather than in an assumption.
What to ask for at specification stage
For the panel itself, the document that answers the fire question is the reaction-to-fire classification and the Declaration of Performance. Kandes publishes both, alongside the technical data sheets, and the panels are specified on commercial projects on that basis. Those two documents answer almost every fire question a specifier puts to a finish supplier.
For the wall, the document that matters is the wall system's own classification report, held by whoever supplies that system. The practical sequence is straightforward: confirm the wall build-up and its classification report, confirm the fixing method against that report's field of application, and get the fire-safety planner's sign-off on the combination. Kandes is a Swiss brand and supplies the panel side of that conversation - the classification, the Declaration of Performance and the data sheets - which is what the fire engineer needs from the finish supplier.
One last point worth making to a client. A gypsum relief wall is chosen because of how it looks and how it takes light, and the fire classification is what lets that choice survive a specification review. The reasoning behind the material itself is covered in our guide to what makes a 3D wall panel premium, and the practical detailing sits in the installation and maintenance guide.
Frequently asked questions
Can 3D wall panels be EI30?
No, and no decorative cladding can be. EI30 is a fire-resistance class under EN 13501-2 that applies to a complete building element, such as an entire partition with its boards, framing and fixings. A panel applied to the face of that wall is not the element being classified, so it cannot carry the rating on its own.
What is the difference between fire resistance and reaction to fire?
Reaction to fire describes how a material behaves when fire reaches it; fire resistance describes how long an assembly holds a fire back. The first is classified under EN 13501-1 on the A1 to F scale and applies to the material. The second is classified under EN 13501-2 in classes such as EI30 and applies to the built element.
What fire class do Kandes panels hold?
Kandes 3D gypsum wall panels are classified A1 (EN 13501-1), non-combustible. A1 is the most stringent class on the reaction-to-fire scale, and it means the panel does not ignite and adds no fire load. The classification documents and the Declaration of Performance are open downloads on the downloads page.
Can I install decorative panels on an EI30-rated wall?
Usually yes, but it has to be confirmed for the specific project rather than assumed. A non-combustible cladding adds no fuel, and in typical build-ups it does not degrade the wall's performance. Because the wall's rating is certified only for its tested configuration, the fixing method and the finished build-up need checking against the wall system's classification report with the system manufacturer or the fire-safety planner.
Does adding a panel change the wall's fire rating?
It can change the basis on which the rating is claimed, which is why the check matters. The panel being non-combustible removes the fuel concern, but fixings through the fire boards, a batten cavity or a non-A1 adhesive are all part of the build-up that was not in the original test. The wall-system manufacturer or fire-safety planner confirms whether the classification still applies as detailed.

If a fire classification is going into a specification, the documents are more useful than any summary of them.
