What Is SPC Click Flooring?
SPC (Stone Plastic Composite) flooring is a multilayer rigid-core resilient floor covering. Its core is typically made from calcium carbonate and PVC-based materials, giving planks greater rigidity than conventional flexible vinyl flooring. A mechanical click-lock system is commonly used for floating installation over suitable, properly prepared subfloors.
Flooring performance depends on more than overall thickness. When evaluating a specific product, review its wear layer, dimensional stability, locking system, installation limitations and verified testing results.
SPC Flooring Layer Structure
Each layer serves a different function; construction and materials vary by model.
Technical Specifications
These configurations are illustrative of this product range. Confirm the exact SKU and agreed values before an order.
| Parameter | Specification |
|---|---|
| Product Type | SPC Rigid Core Vinyl Plank Flooring |
| Core Composition | Calcium Carbonate / PVC-Based Composite |
| Total Thickness | 3–7 mm (depending on model) |
| Plank Size | 152.4 × 914.4 mm / 182 × 1220 mm |
| Wear Layer | 0.3 / 0.5 / 0.7 mm (verify model availability) |
| Installation | Mechanical Click Lock / Floating |
| Surface Finish | Wood-Look and Stone-Look Designs |
| Underlayment | IXPE Optional, subject to product configuration |
| Water Resistance | Water-resistant core; installed floor is not structural waterproofing |
| Fire Classification | Verify the EN 13501-1 report for the exact configuration |
| Application | Residential and commercial interiors where approved by model specifications |
Choosing the Right Wear Layer
Wear layer thickness is separate from overall plank thickness. It helps guide selection but is not, by itself, a formal commercial durability rating.
| Wear Layer | Example Application | What to Check |
|---|---|---|
| 0.3 mm | Homes, apartments and living areas | Expected foot traffic and maintenance conditions |
| 0.5 mm | Offices and rental properties | Use class, abrasion and indentation test data |
| 0.7 mm | Busier retail and commercial projects | Joint performance and project-specific requirements |
Performance Testing & Standards
These standards identify methods or classifications relevant to resilient floor coverings. Listing them here does not claim that every SPC model has been tested or certified.
| Evaluation | Reference | Purpose |
|---|---|---|
| Overall Thickness | ISO 24346 | Measures total flooring thickness |
| Layer Thickness | ISO 24340 | Measures thickness of individual layers |
| Dimensional Stability | ISO 23999 | Assesses heat-related dimensional changes and curling |
| Dimensions | ISO 24342 | Measures plank geometrical characteristics |
| Reaction to Fire | EN 13501-1 | Defines reaction-to-fire classification |
| Mechanical Locking | EN 16511* | Requirements for specified multilayer mechanically locked coverings |
Installation Requirements
Click-lock installation still requires a suitable, prepared substrate and compliance with the selected manufacturer's instructions.
- Subfloor flatness: Subfloor level and surface regularity must be within the model-specific tolerances.
- Moisture control: Test moisture conditions, especially over new concrete.
- Perimeter gaps: Follow prescribed expansion gaps and transition details.
- Underlay compatibility: Do not add underlay unless approved for that locking profile.
- Wet areas: Water-resistant planks do not replace a designed waterproofing system.
- Maintenance: Use appropriate cleaning methods and entrance matting to reduce abrasive soil.
SPC vs. Flexible Vinyl Flooring
| Property | SPC Flooring | Flexible Vinyl |
|---|---|---|
| Core | Rigid composite | Typically flexible PVC-based |
| Flexibility | Relatively low | Generally higher |
| Installation | Commonly click-lock floating | Often glue-down; other methods exist |
| Subfloor | Flatness and moisture restrictions apply | Flatness and moisture restrictions apply |
| Wear Performance | Depends on material and test results | Depends on material and test results |
No product type is universally superior; the appropriate system depends on traffic, substrate, maintenance, project design and cost.
Frequently Asked Questions
Is SPC click flooring completely waterproof?
The SPC core is highly water-resistant, but water may pass through joints or perimeter openings. The installed floor does not replace substrate waterproofing.
Does thicker SPC always last longer?
Can SPC be installed over existing tiles?
Does IXPE make the flooring soundproof?
