Decorative Wall Panels for Architects & Designers | Kandes

Type "decorative wall panels" into a search engine and most of what comes back is sold on price and the promise of a peel-and-stick afternoon: thin PVC sheets, polyurethane foam tiles, printed boards. For a private living room that may be the end of the story. For an architect writing a specification, whether for a hotel lobby, a clinic, a retail flagship, or a house that has to pass a building-control sign-off, it is the start of a different question. Which of these actually holds up as a specified material? The short answer this page argues: an architectural 3D gypsum panel, because it is A1 non-combustible to EN 13501-1, painted on-site to any colour you choose, and joined into one continuous relief rather than a grid of small tiles. The rest is the reasoning a specifier needs.

What "decorative wall panels" actually covers

The phrase is a catch-all. It covers acoustic slat-wood, high-pressure laminate, mineral boards, and, most visibly in search results, lightweight PVC and polyurethane foam panels marketed at homeowners. They share a category name and almost nothing else: fire behaviour, finish, format, and installation method all differ by an order of magnitude across that range. That category confusion is the first thing a specifier has to clear.

It matters now because the surface itself is back in the brief. Interior design through 2025 and 2026 has moved away from flat, refined planes toward tactile, sculptural relief. ArchDaily has described a shift in how interior surfaces are conceived, from applied finishes to architectural frameworks. We covered the same movement in our own look at 2025 textured-wall surface trends. The design appetite is for depth on the wall, for a 3D wall design that reads as architecture. The specification question is which material delivers that depth without creating a compliance or durability problem later.

This is where the category splits. A decorative panel chosen for a quick refresh and an architectural wall panel chosen for a public interior are different decisions. Kandes sits firmly 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.

Three things to verify before you specify

Three properties separate a specification-grade panel from a decorative one. Each is checkable against a document, not a sales claim.

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. A1 is reserved for materials that make no contribution to a fire. The test underneath it, ISO 1182, exposes a sample to roughly 750 °C and allows no sustained flaming. Gypsum earns it honestly: it is a mineral that holds chemically combined water, which is why, per Eurogypsum, it contributes no fuel to a fire. A panel that only claims to be "fire-resistant" with no class and no standard has told you nothing. If you want the full picture of what the classification means on a project, we wrote a dedicated guide to A1 non-combustible panels and EN 13501-1.

Finish control. A commodity panel arrives finished, so you take the colour and sheen the factory chose. A Kandes panel arrives raw and is painted on-site, in any colour, as part of installation. For a specifier 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. That is the design-freedom argument for paintable panels, and it is the reason a fixed-glaze product rarely survives a considered colour brief.

Format and pattern. Commodity decorative panels tend to be small-format and to repeat, so the eye reads a grid and the seams that come with it. Architectural gypsum panels are large-format wall cladding panels designed to join into a continuous pattern, so the relief runs across the wall as one composition rather than a tiled field. The Geometric collection is built around exactly that continuity; a panel such as the NEXUS profile reads as a single architectural surface, not a mosaic.

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

3D gypsum versus commodity PVC and PU-foam panels

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

Two clarifications keep this honest. First, the fire line is the hard one: A1 is a mineral-material class, and an organic plastic cannot reach it. That is chemistry, per the Eurogypsum fire factsheet, not a marketing position. A panel's 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 exactly what a public-interior brief turns on. The same reasoning is why Kandes panels 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

Because the panels are A1 non-combustible and painted on-site, they go where commodity panels cannot. Kandes panels are specified across residential, commercial, hospitality, retail, wellness, office, and public-building interiors, anywhere a feature wall has to satisfy both a design intent and a compliance audit. A Swiss producer sits behind that range, which matters when a project needs documentation as much as it needs a finish.

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 whole point of choosing texture over a flat finish. That 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.

There is one boundary worth stating plainly. The panels are suitable for use in wet areas on walls without direct water contact, and not for steam rooms or constant high-humidity environments; 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 CAD to installed wall

For a designer, the difference between a material they will specify and one they admire is usually workflow. Kandes is built around the specification path: CAD and 3D models for drawing the panel into a scheme, samples on request, and a stock policy that helps a programme hold its dates. Because Kandes is the producer and holds stock of every catalogue model, the lead time is dispatch, not manufacture. The panels are sold directly through kandes.eu and through a curated distributor network, 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 is a briefing aid for that contractor, not a green light for a DIY afternoon. The seamless result is precisely what an unpractised hand tends to lose. The checklist below is what we would confirm on any 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 tiles 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 given project. For a specified interior, 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?

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 under EN 13501-1, the highest European reaction-to-fire class. Many commodity PVC and foam decorative panels are combustible polymers that fall well below A1, 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 decorative commodity panel is typically combustible, factory-finished, small-format, and DIY-oriented. Kandes panels are architectural wall panels that happen to answer the "decorative" search.

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

For a specified interior, gypsum is the stronger choice on the axes that carry compliance and longevity. It is A1 non-combustible 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 in a later cycle. 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 project?

Kandes panels are specified across residential, commercial, hospitality, retail, wellness, office, and public-building interiors. 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?

Kandes panel material starts from around €150/m² excluding VAT, with installation and on-site painting from about €100/m² in the EU, so a fully installed feature wall starts near €250/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.
