The structure of SPC wall panels

An SPC wall panel consists of five layers. At the bottom: a thin acoustic foam backing that compensates for small wall unevenness and provides a mild sound-absorption effect. Above that sits the main body — the SPC core of limestone, polymer and stabilizing additives. The core is the structural heart of the panel, giving it rigidity and water resistance.

On top of the core is a print layer: photorealistic décor — marble, concrete, wood, stone — at 4K resolution. Above that, the wear layer of transparent polymer 0.3–0.5 mm thick. It protects the décor from scratches and UV. Finally, a PU coating (polyurethane seal) that can smooth or texture the surface — depending on the high-gloss or matte variant.

SPC vs. PVC — what is the difference?

PVC (polyvinyl chloride) is the older, cheaper material. PVC panels are cheaper to produce, but have three key drawbacks: they expand more with temperature swings (at 30 °C summer wall temperature, cheap PVC panels can shift out of their click joint), they are softer and more prone to dents, and they often contain plasticisers (phthalates) that can off-gas into the air.

SPC is harder, more temperature-stable and (in our panels) plasticiser-free. The price difference vs. cheap PVC is about 15–25%; the quality difference is more substantial.

SPC vs. MDF panels

MDF (medium-density fibreboard) is a valid alternative in dry areas — bedrooms, living rooms, offices — and is significantly cheaper. The problem: MDF is not waterproof. In the bathroom, kitchen, near radiators or windows with condensation, MDF swells within a few years and is then beyond repair.

For areas with occasional moisture contact, SPC is the safe choice. For strictly dry rooms MDF can be sufficient, but the price saving is modest.

SPC vs. real wood panels

A real wood panel (solid wood, veneer on a carrier board) has its own qualities: incomparable feel, real scent, character. But: maintenance-intensive, prone to cracking in heated air, expensive (€80–150 per m²), moisture-sensitive, can fade over time.

SPC panels in wood look are visually indistinguishable from real wood at arm's length. Whether you prefer real wood or SPC depends heavily on your priorities: if low maintenance and water resistance are key, SPC. If the authenticity of the material itself matters, real wood.

Is SPC safe for health?

High-quality SPC panels (like our NordPaneele) are tested to the TVOC standard (Total Volatile Organic Compounds) and are well below the limits of the EU chemicals regulation REACH. Phthalate-free, PFC-free, formaldehyde-free to E1 standard.

In contrast to some cheap imported panels from uncertain supply chains: their plasticiser content can be detectable by a slight chemical smell when opening the packaging. With our German/European panels there is no such smell — for good reason.
