Gypsum Wall Panels vs 3D Tiles: Swiss Spec Guide | Kandes

On a Swiss project, the choice between a 3D gypsum wall panel and a 3D wall tile is a specification call, not a matter of taste. When the design needs an unbroken pattern across a feature wall, the answer is a large-format gypsum panel: its joints are filled and sanded so the surface reads as one continuous relief, and it carries an A1 non-combustible classification under EN 13501-1, the class Swiss fire practice recognises through the VKF. Reach for 3D wall tiles when the layout genuinely calls for a small, modular, jointed unit, or when the wall sits in a fully wetted zone a panel was never meant for. The sections below set out which to specify, and when.

What separates panels from tiles

Search results blur the two terms, and that is where the confusion begins. They describe different products. A 3D wall tile is a small modular unit, laid in a grid and parted from its neighbours by a grouted joint, exactly as floor and bathroom tiles are. A 3D gypsum wall panel, sometimes searched as a "plaster wall panel", is a large-format element made so that its edges vanish into the wall once fitted and the pattern carries on without a break.

Format is the root of nearly every other difference: how the pattern reads, how the wall is finished, how it is cleaned, and what the installation costs. Swiss interiors have moved firmly toward tactile, sculptural surfaces, the same direction ArchDaily's 2025 interiors review records across the year. The specifier's question is which of the two delivers that effect cleanly, with no compromise tucked away in the detail.

Kandes is a Swiss brand, and it treats every panel as a single architectural surface rather than a tray of small parts. The panels are sold directly through the Kandes website and through a curated network of design-led distributors, so a Swiss studio can specify straight from the catalogue or work through a local partner.

The continuous pattern: the joint question

This is the strongest reason a designer chooses panels over tiles. Any tile layout carries a grid. However tight the grout line, the eye locates it, and the pattern restarts at every joint. For a geometric or flowing relief meant to run the length of a wall, that restart is what undoes the effect.

Kandes panels are drawn so the pattern continues from one panel into the next. Once a skilled installer fills the joints and sands them flush, the separate pieces resolve into a single sculptural surface with no line to break the relief. Plaster-family wall finishes are a familiar register in current interiors, as Dezeen's lookbook of earthy plaster interiors shows; a large-format 3D gypsum panel is the structural-relief form of that look, scaled up and made repeatable.

Put plainly: a 3D wall tile keeps its grid, and a 3D gypsum wall panel is finished to lose it. Where the brief depends on an unbroken pattern, that is the line that decides it.

That seamless field is not the only look Kandes offers, and the join is a choice rather than a fixed property of every panel. When a Swiss project wants defined borders, the Geometric collection is built for exactly that: distinct square panels carrying geometric patterns, with the joint between them kept as part of the design rather than filled away. It reads as a deliberate, modular grid, the crisp look a designer might otherwise reach for tiles to get, but in the same A1 non-combustible (EN 13501-1), paintable, large-format gypsum. With a tile the grid is unavoidable; with Kandes it is something you decide.

Fire class: A1 non-combustible (EN 13501-1, VKF, SIA)

For any public-occupancy interior in Switzerland, the fire question is resolved on paper before the visual brief opens, so it sits near the top of the comparison. EN 13501-1 is the European standard that classifies a construction product's reaction to fire, with classes running from A1 down to F. A1 is the highest: a product that adds no fuel load and releases no flaming droplets at any stage of a fire, per the RISE classification overview. Reaching it means passing the non-combustibility test in EN ISO 1182, where a sample is held near 750°C with almost no temperature rise, mass loss or sustained flaming (Measurlabs on the EN 13501-1 criteria; RISE on the EN ISO 1182 method). In Switzerland these European classes are administered through the VKF (Vereinigung Kantonaler Feuerversicherungen), and they sit inside the fire-protection framework a project documents under SIA practice, so an A1 line item reads cleanly for cantonal building control.

A 3D wall tile has no single fire answer, because "tile" names a format, not a material. Glazed ceramic and porcelain tiles usually sit high on the scale; tiles cut from PVC or polyurethane foam sit far lower and can carry a genuine fuel load. So the fire behaviour of a tiled wall depends on the specific tile, and that is a line the specifier has to verify product by product against the VKF or EN class.

Kandes gypsum wall panels hold the A1 non-combustible classification under EN 13501-1. The class follows from the panel's mineral make-up rather than any coating laid over it. Gypsum behaves well in fire for a concrete reason: it holds chemically bound water that leaves as steam when heated, an endothermic reaction that slows the spread of heat, documented in peer-reviewed work on gypsum plasterboard under natural fire and in Eurogypsum's guidance on gypsum in buildings. The panels are produced in the European Union to that standard and shipped into Switzerland with the classification documented. Our earlier piece on A1 non-combustible wall panels and EN 13501-1 reads the standard in full.

Finish, colour and durability

A glazed tile arrives in its final colour, and the maker's range is the ceiling. A Kandes panel arrives uncoated and is painted on-site in the colour the project specifies, with the chosen paint system. The surface is the structure; the colour is a separate decision the designer keeps. That lifts the catalogue-colour constraint entirely, which is why Swiss studios tend to value the paintable property more than they expect at the outset.

Gypsum is a low-VOC mineral material, useful where indoor air is part of the brief, and the finished panel contains no toxic or hazardous binders. For durability, the panels are made to hold their structure and appearance over time, and they are repaintable in the first four years of a normal interior refresh cycle, with on-site touch-ups for handling marks rather than any special cleaning routine.

The wet-area rule is where an honest answer matters. Gypsum wall panels suit wet-adjacent rooms such as bathrooms and kitchens, on walls without direct water contact and without constant high humidity; on secondary walls in those rooms, the installer applies a splash-resistant paint as the on-site finish. Steam rooms, saunas, pool surrounds and direct shower-spray zones fall outside what the panel is built for. That is the one place where a fully wetted, glazed-tile system is the correct specification and a panel is not.

Gypsum wall panels vs 3D tiles at a glance

The table sets the two side by side on the axes a Swiss specifier actually weighs. The tile column is the typical case; a given tile may sit higher or lower on any row by material.

3D gypsum wall panels vs 3D wall tiles: the specification view

Where each fits on a Swiss project, and how it goes in

Read the table as a routing rule, not a scoreboard. Specify 3D wall tiles where the design wants a deliberate grid, a mosaic detail, or full coverage of a wetted surface, and where small modular units suit the geometry. Specify 3D gypsum wall panels where the pattern has to run unbroken: the reception wall a guest meets on entering a Zurich hotel, a Geneva boutique's brand wall, or the principal wall of a room where one surface is meant to carry the space.

For the geometric, architectural register this comparison tends to attract, the relevant range is the Geometric range; the full Kandes catalogue also runs to flowing and classic patterns. Swiss specifiers working to SIA documentation can request the specification details for the chosen panels.

On installation, treat the panel as architectural work. We advise professional installation: a gypsum or plaster finishing contractor is the right trade, because the continuous-pattern result rests entirely on the joints being filled and sanded correctly and the substrate being prepared properly. Self-installation is realistic only for someone with real prior tiling or plastering experience, and even then it warrants caution on larger walls. The joint detailing, substrate preparation and finishing are set out in the installation and maintenance guide.

Frequently asked questions

Are 3D gypsum wall panels better than 3D wall tiles?

Neither wins outright; they answer different briefs. Gypsum panels lead where the design needs an unbroken, continuous pattern and a documented A1 fire classification across a large feature wall. Tiles lead in small modular layouts and in fully wetted zones such as showers, where a glazed system is the right call. The brief decides, not a ranking.

What is the difference between 3D wall panels and 3D wall tiles?

A 3D wall tile is a small modular unit set in a grid with grouted joints; a 3D gypsum wall panel, often searched as a plaster wall panel, is a large-format element whose joints are filled and sanded so the relief reads as one continuous surface. That format gap drives how the pattern reads, how the wall is finished, and which trade installs it.

Are 3D gypsum wall panels fire rated for Swiss projects?

Kandes gypsum wall panels are A1 non-combustible under EN 13501-1, the highest reaction-to-fire class, recognised in Switzerland through the VKF and consistent with SIA fire-protection practice. A1 means the panel adds no fuel load and produces no flaming droplets. A 3D wall tile's fire behaviour depends on its material, so it has to be checked product by product.

Are 3D gypsum wall panels seamless, or do they show joints?

Most Kandes panels are designed to read seamless: they join so the pattern carries from one to the next, and once an installer fills and sands the joints, the pieces merge into a single continuous relief with no visible grid line. If a project wants defined borders instead, the Geometric collection is made for that, keeping the joint between its distinct square panels as part of the design. The difference from a tile is that with gypsum you decide whether the grid shows.

Can 3D gypsum wall panels be painted to a Swiss project's colour?

Yes. Every Kandes panel is fitted uncoated and painted on-site in any colour, with the project's specified paint system. The colour is the designer's decision rather than a pick from a fixed catalogue, which is a clear difference from a glazed tile that arrives in its final finish.

Can 3D gypsum wall panels be used in bathrooms or wet areas?

They can be used on wet-adjacent walls, such as in bathrooms, where there is no direct water contact and no constant high humidity; on secondary walls in wet rooms, the installer applies a splash-resistant paint. They are not for steam rooms, saunas, pool surrounds or direct shower-spray zones, where a fully wetted glazed-tile system is the right specification instead.

Can I install 3D gypsum wall panels myself?

We advise professional installation. A gypsum or plaster finishing contractor is the appropriate trade, because the seamless result depends on correct joint filling, sanding and substrate preparation. Self-installation is realistic only with genuine prior tiling or plastering experience, and even then we suggest caution on larger walls; the installation guide is a briefing aid, not a green light for a first-time fitter.
