SPC Flooring: 5 Pros & 4 Cons You Must Know Before Buying

Product Definition

SPC flooring, short for Stone Plastic Composite flooring, is a rigid-core vinyl flooring system engineered with a high-density limestone-based core. It is designed for dimensional stability, commercial durability, and moisture resistance, making it suitable for high-traffic residential and commercial environments.

Technical Parameters & Specifications

SPC flooring performance is determined by standardized, measurable parameters used across international projects and procurement documents.

• Total thickness: 3.5–7.0 mm

• Wear layer thickness: 0.3 / 0.5 / 0.7 mm

• Core density: 1900–2100 kg/m³

• Locking system: Unilin / Valinge compatible

• Slip resistance: R9–R10

• Fire rating: Bfl-s1 (EN 13501-1)

• Formaldehyde emission: E1 / CARB Phase II compliant

Structure & Material Composition

SPC flooring uses a multi-layer engineered structure optimized for stability and long-term performance.

• UV Coating Layer: Scratch resistance and surface protection

• Wear Layer: Transparent PVC layer resisting abrasion

• Decor Film: High-definition printed wood or stone visuals

• SPC Core: Limestone powder + PVC resin composite

• Balance Layer: Optional IXPE/EVA acoustic underlayment

Manufacturing Process

Industrial SPC flooring production follows a continuous, tightly controlled process to ensure consistency.

1. Raw material batching (PVC resin, calcium carbonate, stabilizers)

2. High-speed hot mixing and cooling system

3. Extrusion molding via twin-screw extruder

4. Calendering and thickness calibration

5. UV coating curing and surface treatment

6. Precision profiling and locking milling

7. Final inspection, packaging, and palletization

Industry Comparison

Application Scenarios

SPC flooring is widely adopted across projects requiring stability and predictable lifecycle costs.

• Commercial offices and business centers

• Hospitality projects and serviced apartments

• Retail chains and shopping malls

• Education and healthcare facilities

• Residential renovation and new builds

Core Pain Points & Solutions

• Concern: Floor expansion in varying climates
       Solution: Rigid SPC core minimizes thermal movement

• Concern: Moisture damage
       Solution: Waterproof composite structure

• Concern: Long-term wear in high traffic
       Solution: Commercial-grade wear layers (≥0.5 mm)

• Concern: Installation complexity
       Solution: Click-lock floating installation systems

Risk Warnings & Mitigation

While SPC flooring offers robust performance, improper selection or installation can introduce risks.

• Avoid ultra-thin products below 3.5 mm for commercial use

• Ensure subfloor flatness within ±2 mm per 2 meters

• Confirm wear layer thickness meets project traffic load

• Verify acoustic requirements before selecting underlayment

Procurement & Selection Guide

1. Define project application (commercial vs residential)

2. Confirm required thickness and wear layer class

3. Request compliance documents and test reports

4. Evaluate locking system compatibility

5. Check batch consistency and color tolerance

6. Review warranty terms and lifecycle cost

Engineering Case Example

In a 12,000 m² mixed-use commercial complex, SPC flooring with a 5.0 mm total thickness and 0.5 mm wear layer was specified. The project required minimal downtime, moisture tolerance, and acoustic control. Post-installation inspections after 24 months showed no visible deformation, joint failure, or surface wear.

FAQ

• Is SPC flooring suitable for heavy commercial traffic?
  Yes, with ≥0.5 mm wear layer.

• Does SPC flooring require acclimation?
  Short acclimation is recommended.

• Can SPC be installed over existing tiles?
  Yes, if the surface is flat.

• Is SPC flooring waterproof or water-resistant?
  The core is waterproof.

• What is the expected service life?
  15–25 years depending on use.

• Does SPC flooring emit VOCs?
  Certified products meet E1 standards.

• Is underlayment mandatory?
  Optional, project-dependent.

• Can SPC flooring be repaired?
  Damaged planks can be replaced individually.

• Is it suitable for underfloor heating?
  Yes, within temperature limits.

• What maintenance is required?
  Routine cleaning only.
