What is SPC flooring, and how does it differ from other types of vinyl flooring?
Mar 31, 2025
SPC (Stone Plastic Composite) flooring is a type of rigid core vinyl flooring known for its durability, waterproof properties, and stability. It differs significantly from traditional vinyl flooring options like LVT (Luxury Vinyl Tile) and WPC (Wood Plastic Composite) in terms of composition, performance, and application. Here's a detailed breakdown:
1. What is SPC Flooring?
Core Composition: SPC flooring features a dense core made of limestone powder (calcium carbonate), PVC, and stabilizers. This combination creates a rigid, stone-like structure that resists denting and temperature fluctuations
Layered Structure:
Wear Layer: A transparent top layer (0.3–0.5mm thick) protects against scratches and stains
.Design Layer: High-definition printed patterns mimic wood, stone, or tile aesthetics
.SPC Core: The rigid limestone-PVC core provides dimensional stability
.Underlayment: Optional foam or cork backing for noise reduction and subfloor smoothing
Key Features:
100% Waterproof: Ideal for bathrooms, kitchens, and basements
.High Durability: Resists scratches, dents, and heavy foot traffic, with a lifespan of 20–30+ years
.Low Maintenance: Requires only sweeping and occasional mopping
2. How SPC Differs from Other Vinyl Flooring
SPC vs. LVT (Luxury Vinyl Tile)
| Aspect | SPC Flooring | LVT |
|---|---|---|
| Core Material | Rigid limestone-PVC core
1 4 |
Flexible vinyl or fiberglass layers
2 5 |
| Thickness | 4–9.7mm (thinner cores possible due to rigidity)
2 3 |
2–5mm (thinner and more flexible)
2 5 |
| Installation | Click-lock floating system
1 4 |
Glue-down or loose-lay
2 5 |
| Stability | Highly stable; minimal expansion/contraction
1 4 |
Prone to warping if subfloor is uneven
2 |
| Comfort | Harder underfoot due to rigid core
1 5 |
Softer, more flexible feel

SPC vs. WPC (Wood Plastic Composite)
| Aspect | SPC Flooring | WPC |
|---|---|---|
| Core Material | Solid limestone-PVC core | Foamed PVC with wood flour or fibers |
| Weight | Heavier due to dense stone content | Lighter (aerated core) |
| Dent Resistance | Superior (rigid structure) | Moderate (softer core) |
| Thickness | Typically 4–9.7mm | 6.5mm+ (thicker for structural strength)
|
| Comfort | Harder underfoot
|
Softer, with better sound absorption

SPC vs. Traditional Vinyl Sheet/Plank
Durability: SPC outperforms traditional vinyl in scratch and dent resistance due to its rigid core
.Waterproofing: Both are waterproof, but SPC's stability prevents warping in humid conditions
.Cost: SPC is pricier (3.50–3.50–8/sq.ft.) than basic LVT (2–2–7/sq.ft.) but offers longer-term value
3. Ideal Applications for SPC Flooring
High-Traffic Areas: Commercial spaces, entryways, and kitchens
.Moisture-Prone Zones: Bathrooms, laundry rooms, and basements
.Climate Variability: Stable performance in regions with temperature/humidity swings
4. Limitations of SPC Flooring
Comfort: Harder underfoot compared to WPC or cushioned LVT
.Subfloor Requirements: Requires a flat surface; uneven subfloors may necessitate leveling
.Cost: Higher initial investment than basic vinyl options
Summary
SPC flooring stands out for its rigid, stone-based core, offering unmatched durability and stability compared to traditional vinyl or WPC. While it may lack the softness of WPC, its resistance to moisture, dents, and wear makes it ideal for demanding environments. For those prioritizing longevity over cushioning, SPC is a top choice
