| SPC Core Composition | Rigid mineral-polymer composite, commonly based on calcium carbonate filler and PVC binder. | The core provides rigidity, moisture resistance, and resistance to indentation under normal residential and commercial loads. | Request the core formulation, product density, test reports, and declared tolerances rather than judging quality by appearance alone. |
| Overall Thickness | Common commercial constructions are approximately 3.5–8.0 mm, including the wear layer and any attached underlay. | Thickness affects joint robustness, floor height transitions, acoustic performance, and tolerance of minor substrate irregularities. | Confirm whether the stated thickness includes the attached pad. Coordinate door clearances, stair nosings, and transition profiles. |
| Core Density | Many rigid SPC products fall within roughly 1,900–2,100 kg/m³, but the specified value varies by formulation. | Higher density can support stiffness and impact resistance, while excessive weight may increase handling and logistics demands. | Compare density together with indentation, impact, and dimensional-stability results; density alone is not a complete quality indicator. |
| Wear Layer Thickness | Typical options include 0.20 mm, 0.30 mm, 0.50 mm, and 0.70 mm. | The wear layer protects the printed design from abrasion and is a major factor in suitability for residential, hospitality, retail, and office areas. | Match the thickness to traffic intensity and verify abrasion classification through an applicable test report. |
| Abrasion Classification | Common EN 16511 classifications range from 23 for heavy domestic use to 33 for heavy commercial use; some products are classified higher. | A harmonized use class helps compare products for different occupancy levels and international specifications. | Use the classification stated in the technical documentation and confirm that the test method is accepted in the destination market. |
| Surface Finish | Common finishes include matte, embossed-in-register, wood texture, stone texture, and polyurethane-treated surfaces. | Texture influences visual realism, slip behavior, cleaning effort, and the visibility of scratches or dust. | Check slip-resistance results, stain resistance, cleanability, gloss variation, and sample performance under project lighting. |
| UV and Protective Coating | UV-cured polyurethane or acrylic coatings are commonly used to improve surface protection and reduce soiling. | Sun-facing areas, glazed façades, and retail spaces can expose flooring to prolonged light and cleaning cycles. | Request light-resistance, stain-resistance, and chemical-resistance test data where the project has strong solar exposure or intensive cleaning. |
| Click Joint Geometry | Common systems include angle-angle, angle-drop, and fold-down profiles; joint design varies by plank format and core construction. | The joint affects installation speed, end-joint strength, replacement procedures, and the risk of chipping during assembly. | Test the actual production batch for locking force, joint gap, edge damage, and ease of disassembly before approval. |
| Click Joint Tolerance | A practical project target is a visually closed joint with no material step or opening under normal installation conditions; exact tolerances must be manufacturer-declared. | Tight, consistent joints reduce dirt collection, moisture entry, visual variation, and callbacks across different installation teams. | Inspect joint flatness and gap performance using multiple cartons, production lots, and installers with different experience levels. |
| Dimensional Stability | SPC products are generally more dimensionally stable than many flexible resilient floors, but expansion can still occur with temperature changes. | Global projects may involve hot climates, cold transport routes, large glazed areas, and rapid indoor temperature changes. | Review heat-aging and dimensional-stability data, follow perimeter-clearance requirements, and avoid blocking a floating floor. |
| Moisture Performance | The SPC core itself is water-resistant, but moisture can still affect the subfloor, joints, adhesives, skirtings, and adjacent materials. | Water-resistant construction is useful for kitchens, entrances, and humid regions, but it does not correct an unprepared wet substrate. | Measure subfloor moisture according to the applicable local method and design wet-area details separately from the floor covering. |
| Subfloor Flatness | Many click-floor installation guides require a flatness of approximately 3 mm over 2 m, although the exact limit is product-specific. | Rigid planks can bridge small imperfections but may show movement, hollow spots, or joint stress on uneven substrates. | State the permitted flatness, dryness, cleanliness, and structural requirements in the project installation specification. |
| Underfloor Heating Compatibility | Many SPC floors are suitable for water-based or electric systems when approved by the product documentation; surface temperature is commonly limited to about 27°C. | Incorrect heating control can cause excessive expansion, joint stress, or surface damage. | Verify the heating-system type, maximum surface temperature, commissioning procedure, and thermal resistance of any attached underlay. |
| Acoustic Construction | Attached pads commonly use PE foam, IXPE, or EVA. Impact-sound improvement depends on the complete floor-and-subfloor assembly. | Hotels, apartments, offices, and mixed-use buildings often have project-specific impact and airborne sound targets. | Use laboratory or field acoustic results for the complete assembly; do not compare underlay claims in isolation. |
| Fire Performance | Many resilient floor products are assessed under EN 13501-1, with classifications depending on the full construction and underlay. | Fire requirements vary by building type, escape route, occupancy, and national code. | Obtain a valid classification report for the exact product, thickness, backing, and adhesive or installation assembly. |
| Slip Resistance | Wet and dry slip performance depends on the surface texture, contamination, cleaning regime, and test method. | Entrances, kitchens, healthcare spaces, and humid climates require greater attention to contamination and wet-foot traffic. | Select the applicable local test standard and specify maintenance procedures together with the flooring product. |
| Indoor Air and Chemical Emissions | Emissions are influenced by the flooring, backing, packaging, adhesive, and installation environment. | Different countries and green-building systems may set limits for VOC emissions and restricted substances. | Request current third-party emission testing and declarations for the exact construction supplied to the project. |
| Format and Joint Layout | Typical plank widths are approximately 150–300 mm, with lengths commonly around 900–1,800 mm; actual formats vary widely. | Longer or wider planks can change installation productivity, waste percentage, visual scale, and joint alignment requirements. | Prepare a room-by-room layout, include expansion clearances, and calculate waste for irregular areas and directional patterns. |
| Installation Method | Most SPC click floors are installed as floating systems without full-surface adhesive, subject to product instructions. | Floating installation can shorten installation time and simplify localized replacement, but movement control remains essential. | Confirm perimeter gaps, maximum uninterrupted area, heavy-fixed-object restrictions, expansion profiles, and repair procedures. |
| Global Quality-Control Plan | Key controls include thickness, squareness, plank dimensions, joint fit, surface appearance, packaging, and batch traceability. | Consistent production is critical when the same design is installed across multiple countries and climate zones. | Approve a reference sample, define inspection levels, retain production samples, and verify that all shipments match the approved specification. |
