Decorative Wall Panels for Swiss Architects | Kandes

In a Swiss specification, a decorative wall panel has to clear two gates at once: the design intent and the cantonal fire rules. Search "decorative wall panels" and most results are commodity PVC and polyurethane foam sold on price and a peel-and-stick weekend. For a private flat that may be enough. For an architect specifying a hotel lobby in Zurich, a clinic in Geneva, or a retail interior that has to satisfy a VKF fire review, it is the start of a harder question: which of these holds up as a specified material? The short answer this page makes is an architectural 3D gypsum panel from Kandes, because it is A1 non-combustible to EN 13501-1, painted on-site to any colour, and joined into one continuous relief rather than a grid of small tiles.

What "decorative wall panels" actually covers

The term is a catch-all. Swiss searches reach it through several doors: 3D wall covering, 3D wall panelling, dimensional wall panels, modern 3D wall panels. They all land on the same crowded category: acoustic slat-wood, high-pressure laminate, mineral boards, and the lightweight PVC and foam panels aimed at homeowners. These share a name and little else. Reaction to fire, finish, format, and installation differ by an order of magnitude across the range, and clearing that confusion is the specifier's first job.

The surface is back in the brief. Interior design through 2025 and 2026 has shifted away from flat, refined planes toward tactile, sculptural relief, a move ArchDaily traces from applied finishes to architectural frameworks. A Swiss specifier reading that trend wants depth on the wall that still passes a building-control review. The question is which material delivers it without creating a compliance or durability problem later.

This is where the category splits. A panel chosen for a quick refresh and an architectural panel chosen for a public Swiss interior are different decisions. Kandes sits at the second end: these are architectural 3D gypsum wall panels, not commodity decorative panels. The distinction is not branding. It is fire class, finish control, and format, and each one is verifiable against a document.

Three things a Swiss specifier should verify

Three properties separate a specification-grade panel from a decorative one. Each is checkable, which matters more in Switzerland than almost anywhere.

Fire classification. Ask for the reaction-to-fire class and the standard behind it. Kandes panels are A1 non-combustible under EN 13501-1, the top of the European scale, which runs from A1 down to F. In the Swiss framework that A1 class corresponds to the VKF (Vereinigung Kantonaler Feuerversicherungen) reaction-to-fire category RF1, the no-contribution-to-fire grade that cantonal fire rules require in commercial buildings. The test underneath the class, ISO 1182, holds a sample at roughly 750 °C with no sustained flaming. Gypsum earns it: it is a mineral that holds chemically combined water, which is why, per Eurogypsum, it adds no fuel to a fire. A panel that only claims to be "fire-resistant" with no class and no standard has told you nothing. For the full picture, we wrote a guide to A1 non-combustible panels and EN 13501-1.

Finish control. A commodity panel arrives finished, so you take the factory's colour and sheen. A Kandes panel arrives raw and is painted on-site, in any colour, as part of installation. That removes a constraint: the wall matches the scheme exactly, in the same paint system as the rest of the interior, and can be refreshed to a new colour in a later cycle. It is the design-freedom argument for paintable panels, and the reason a fixed-glaze product rarely survives a considered Swiss colour brief.

Format and pattern. Commodity decorative panels tend to be small-format and to repeat, so the eye reads a grid and its joints. Architectural gypsum panels are large-format and designed to join into a continuous pattern, so the relief runs across the wall as one composition. The Soft Forms range is built around that continuity, a dimensional wall panel that reads as a single architectural surface, not a mosaic.

One fact belongs to the material rather than to any single property. Kandes panels are produced in the European Union, from natural gypsum with reinforcement and no toxic or hazardous binders in the finished panel. Gypsum is a low-VOC mineral material, which reads well in interiors where indoor-air quality is part of the brief. None of that is true of a printed plastic sheet.

3D gypsum versus commodity PVC and PU-foam panels

The gap is clearest side by side. The comparison sets an architectural 3D gypsum panel against the two commodity formats that dominate the "decorative wall panels" category in Switzerland, PVC and polyurethane foam, on the axes a Swiss specifier weighs.

Two clarifications keep this honest. First, the fire line is the hard one: A1 (and its VKF RF1 equivalent) is a mineral-material class, and an organic plastic cannot reach it. That is chemistry, per the Eurogypsum fire factsheet, not a marketing position. Smoke and droplet behaviour sit alongside the main class as the s and d sub-ratings within the EN 13501-1 system. Second, none of this makes PVC or foam "bad." For a temporary install or a tight budget they do a job. It makes them a different specification, and the difference is what a Swiss public-interior brief turns on. The same reasoning is why these read as a premium material rather than a decorative add-on, which we set out in what makes a 3D wall panel premium.

Where 3D gypsum panels are specified in Switzerland

Because the panels are A1 non-combustible and painted on-site, they go where commodity panels cannot. Across Switzerland they are specified in hospitality, retail, wellness, office, residential, and public-building interiors, from a Zurich hotel lobby to a Geneva boutique to a clinic reception, anywhere a feature wall has to satisfy both a design intent and a cantonal compliance review. A Swiss producer sits behind that range, with the SIA-based documentation and VKF fire framing a specifier needs to close out a submission.

Light is part of the specification, not a complication. Daylight and artificial light rake across the relief and reveal its depth through the day; the surface stays alive as the light moves, which is the point of choosing texture over a flat finish. It holds behind a media wall too. The shifting glow of a screen keeps the relief reading, and the panel frames the screen as a deliberate backdrop that gives the media wall depth even when the television is off.

One boundary is worth stating plainly. The panels suit wet areas on walls without direct water contact, and not steam rooms or constant high-humidity zones; on secondary walls in wet rooms, the installer applies a splash-resistant paint as the on-site finish. That keeps a bathroom feature wall in scope while keeping the panel away from the conditions it is not made for.

Specifying Kandes: from sample to installed wall

For a Swiss designer, the difference between a material they specify and one they admire is usually workflow and certainty. Kandes is built around that path: samples on request, and a stock policy that helps a Swiss programme hold its dates. Because Kandes is the producer and holds stock of every catalogue model, the lead time is dispatch rather than manufacture. The panels are sold directly through kandes.ch and through an official Swiss distribution partner Hochwert, so a specifier can source them through whichever channel suits the project.

Installation is a trade job, and the specification should say so. We advise professional installation by a gypsum or plaster finishing contractor: the panels are bonded to a prepared substrate, and the continuous pattern depends on a properly aligned, filled, and sanded joint before painting. The installation and maintenance guide briefs that contractor; it is not a DIY green light, because the seamless result is exactly what an unpractised hand tends to lose. The checklist below is what we would confirm on any Swiss decorative-panel specification before it goes into a drawing set.

Frequently asked questions

What are decorative wall panels?

Decorative wall panels are surface-mounted panels that add pattern, texture, or relief to a wall, ranging from commodity PVC and foam to specification-grade architectural panels. The category spans a wide range of materials and fire behaviours, so the name alone tells you little about whether a panel suits a Swiss project. The meaningful question is the material: an architectural 3D gypsum panel behaves very differently from a printed plastic sheet.

Are decorative wall panels fire rated for Swiss buildings?

Some are and most are not, which is why the class and the standard matter more than the word "fire-rated." Kandes architectural gypsum panels are A1 non-combustible to EN 13501-1, the class that corresponds to the Swiss VKF reaction-to-fire category RF1 required in commercial buildings. Many commodity PVC and foam panels are combustible polymers well below that grade, so on any public-interior project the classification has to be confirmed, not assumed.

What is the difference between decorative wall panels and architectural wall panels?

"Decorative wall panel" describes an effect; "architectural wall panel" describes a material that can be specified into a building. The practical differences are fire class, finish control, format, and installation: an architectural 3D gypsum panel is A1 non-combustible, painted on-site, large-format, and contractor-installed, where a commodity panel is typically combustible, factory-finished, small-format, and DIY-oriented.

Are 3D gypsum wall panels better than PVC or foam decorative panels?

For a specified Swiss interior, gypsum is the stronger choice on the axes that carry compliance and longevity. It is A1 non-combustible (VKF RF1) rather than a combustible plastic, painted to your exact colour rather than a fixed factory finish, and joined into a seamless pattern rather than a visible grid. PVC and foam remain reasonable for a temporary or low-budget private refresh. They are simply a different specification.

Can decorative wall panels be painted?

Kandes gypsum panels are designed to be painted on-site in any colour, as part of installation. That gives the specifier exact control of the finish and lets the wall be refreshed to a new colour later. Most commodity PVC and foam panels arrive factory-finished and cannot be repainted to match a scheme.

Where can decorative wall panels be used in a Swiss project?

Kandes panels are specified across residential, commercial, hospitality, retail, wellness, office, and public-building interiors in Switzerland. They suit wet-adjacent rooms such as bathrooms on walls without direct water contact, but not steam rooms, saunas, or constant high-humidity zones. On secondary walls in wet rooms, the installer applies a splash-resistant paint as the finish.

Can I install decorative wall panels myself?

We advise professional installation by a gypsum or plaster finishing contractor. The panels are bonded to a prepared substrate, and the seamless continuous pattern depends on a correctly aligned, filled, and sanded joint before painting, the part most likely to go wrong by hand. Self-installation is realistic only for someone with genuine prior plastering or gypsum experience, and even then we would advise caution on larger walls.

How much do 3D gypsum decorative wall panels cost in Switzerland?

Kandes panel material starts from around CHF 150/m² excluding VAT, with installation and on-site painting from about CHF 150/m², so a fully installed feature wall starts near CHF 300/m². The figure reflects a specification-grade, A1 non-combustible, on-site-painted architectural surface rather than a commodity decorative panel. Final cost depends on the panel family, the wall area, and the finish specified.
