Large-Format SPC Wall Panels — A High-Resilient Rapid Walling System
A lightweight, fast-track non-structural interior cladding system engineered to replace tile and wood slips in heavy-traffic commercial spaces. Panels install directly over existing tile or drywall with high-grab adhesive — zero-cure, zero wet-work — in floor-to-ceiling heights up to 2900 mm with no horizontal seams.
Ecoflors large-format SPC wall panels are lightweight, non-structural interior cladding made from a high-density stone-polymer composite core (1.95–2.05 g/cm³). Engineered as a rapid walling system, they install directly over existing tile, drywall or cement board with high-grab adhesive — no cure time and no wet trades — in floor-to-ceiling panels up to 2900 mm tall and 1250 mm wide, from 2.5 to 5.0 mm thick. Panels can be supplied tested to EN 13501-1 B-s1,d0 and ASTM E84 Class A surface-burning ratings for commercial interiors. Factory-direct from Changzhou and Jiaxing, China since 2017; MOQ 800 m² per SKU. Contact: WhatsApp +86 134 8633 9267 or sales@ecoflors.com.
Why specifiers choose the system
Three engineering decisions separate a large-format SPC walling system from commodity wall cladding — each one written for the realities of a commercial fit-out programme.
Floor-to-Ceiling Monolithic Design
Single panels up to 2900 mm run floor-to-ceiling with no horizontal joints. That removes the primary path for moisture ingress, lowers mould risk in wet zones, and gives a seamless architectural scale that tiled walls cannot match.
Substrate Load Optimisation
A thin 2.5–5.0 mm profile on a 1.95–2.05 g/cm³ rigid core delivers high impact resistance without heavy dead-load on gypsum drywall or lightweight partition systems — so the system suits renovation and stud-wall construction alike.
Complete System, Not a Commodity
Matching heavy-duty trims — internal & external corners, J-trims and H-splices — are indexed to every panel format, positioning the system as a full modular cladding solution rather than a raw panel supply.
Unlike horizontal flooring, a vertical surface faces scuffs and impact — not heavy foot-traffic friction. The system therefore specifies a 0.2 mm wear layer: a deliberate engineering optimisation that delivers full scratch and stain resistance for wall use while removing the redundant dead-load that a thicker, flooring-grade wear layer would add to a large vertical span. It is right-sized for the application, not under-built.
Engineering specification
Verified performance thresholds for the panel core and surface. Batch values are confirmed on the technical data sheet (TDS) and third-party test report for each article.
| Property | Value | Standard / Note |
|---|---|---|
| Core density | 1.95–2.05 g/cm³ | High-density rigid stone-polymer core (ISO 1183) |
| Wear layer | 0.2 mm | Engineered for vertical scuff resistance; minimises dead load |
| Dimensional stability | ≤ 0.10% | EN ISO 23999 — zero joint separation under thermal shift |
| Curling resistance | ≤ 2 mm | Flush, long-term flat adhesion over large vertical spans |
| Peel strength | ≥ 50 N/50mm | Anti-delamination of decor film and rigid core |
| Thickness | 2.5 – 5.0 mm | Optimised profile range |
| Dimension | Available sizes (mm) | Design rationale |
|---|---|---|
| Width | 950 · 1220 · 1230 · 1240 · 1250 | Matches modular drywall / stud spacing |
| Length / Height | 2440 · 2500 · 2600 · 2700 · 2800 · 2900 | Floor-to-ceiling single-panel layout — eliminates horizontal seams |
Exact tolerances, squareness and panel weights per format are confirmed on the TDS for each article.
Surface-burning classification for wall use
For commercial interiors — hospitality corridors, public washrooms, retail — wall finishes carry a fire requirement distinct from flooring. The system can be supplied tested to the recognised wall-surface classifications below. Note these are reaction-to-fire / surface-burning classes for the panel, reported from the third-party test for each article and decor.
| Region | Standard | Classification | What it covers |
|---|---|---|---|
| Europe | EN 13501-1 | B-s1,d0 | Reaction to fire (B), low smoke (s1), no flaming droplets (d0) — a wall class (not the Bfl floor class) |
| United States | ASTM E84 | Class A | Surface burning: flame spread ≤ 25, smoke developed ≤ 450 (Steiner Tunnel Test) |
| Smoke / droplets | EN 13823 · EN ISO 11925-2 | s1 · d0 | Single-flame and ignitability sub-tests behind the EN class |
Specification boundary: a surface-burning class (ASTM E84 Class A or Euroclass B-s1,d0) describes the panel finish, not a whole-wall fire-resistance rating. The two standards use different test methods and are not interchangeable for code compliance. For combustible cladding on buildings above local height thresholds, full-system tests such as NFPA 285 may apply — confirm the requirement with the project’s fire engineer and authority having jurisdiction (AHJ). Our engineering team supplies the third-party report for the exact article to support that submittal.
SPC wall panel vs. traditional wall finishes
How the rapid walling system compares with the materials it most often replaces in commercial fit-outs. Indicative comparison for specification screening; confirm project-specific values against test reports.
| Criterion | SPC Wall Panel | Ceramic Tile | ACP (Alu. Composite) | Wood Slip / Veneer |
|---|---|---|---|---|
| Install speed | Fast — dry, adhesive, no cure | Slow — wet trades, grout, cure | Medium — framing / fixings | Medium — adhesive + finishing |
| Wet-work on site | None | High (mortar / grout) | Low | Low |
| Horizontal joints | None to 2900 mm | Many (tile grid) | Per panel size | Per plank |
| Water absorption | 0% (core) | Low (body) · grout porous | 0% | Absorbs / swells |
| Dead load on partition | Low (2.5–5 mm) | High (tile + mortar bed) | Low–medium | Medium |
| Fire (wall surface) | B-s1,d0 / Class A (tested) | Non-combustible | Varies (core dependent) | Combustible unless treated |
| Impact / scuff | High (rigid core) | Brittle — chips / cracks | Dents | Scratches / dents |
| Renovate over old tile | Yes — direct overlay | Usually strip first | Sub-frame needed | Prep needed |
Matching heavy-duty trim profiles
Every panel format is supported by a coordinated trim set, so the system delivers a finished detail at every junction — not just flat sheets.
Internal Corners
Clean 90° inside-corner transition without on-site mitring.
External Corners
Impact-protected outside-corner profile for high-traffic edges.
J-Trims
Edge termination at openings, ceilings and floor lines.
H-Splices
Flush vertical panel-to-panel join where width splicing is needed.
Direct overlay, dry installation
Substrates & adhesive
The system is designed for direct overlay onto sound, flat, dry substrates using a high-grab adhesive — eliminating wet trades and cure time on site.
- Existing ceramic tile (sound, well-bonded)
- Gypsum drywall / plasterboard
- Cement board and skimmed masonry
Substrate flatness tolerance, primer requirements and the exact adhesive grade are confirmed on the installation guide and TDS for the project — our engineering team advises on the correct system for your substrate.
Movement & joints
Large vertical spans need correct perimeter and movement-joint clearance to stay flush as the building moves and temperatures shift. The ≤ 0.10% dimensional stability (EN ISO 23999) and ≤ 2 mm curling figures support flat, long-term adhesion, but design clearances must still follow the installation guide.
