Rigid Core Flooring: A Quick Introduction
SPC and WPC flooring are both “rigid core” vinyl floors designed to solve the problems of traditional flexible vinyl: dents, expansion, and uneven subfloors. They combine a waterproof core with a realistic printed wear layer. The core material is the main difference.
What Is SPC Flooring?
SPC (Stone Plastic Composite) flooring has a core made of limestone powder blended with PVC. This makes it extremely dense, rigid, and dimensionally stable. SPC is the most stable floor on the market for temperature changes.
What Is WPC Flooring?
WPC (Wood Plastic Composite) flooring uses a foamed wood-plastic core that is softer and more flexible than SPC. This gives WPC a warmer, slightly cushioned feel underfoot and better sound insulation.
Side-by-Side Comparison
| Factor | SPC Flooring | WPC Flooring |
|---|---|---|
| Core material | Limestone + PVC | Wood fiber + plastic foam |
| Waterproof | 100% waterproof | 100% waterproof |
| Stability | Excellent (minimal expansion) | Good |
| Comfort underfoot | Firmer, cooler | Softer, warmer |
| Sound insulation | Good | Better |
| Thickness range | 4mm-8mm | 5mm-10mm |
| Typical price | Lower | Higher |
| Best for | Commercial, kitchens, basements | Bedrooms, living rooms, rentals |
When to Choose SPC
- High-traffic commercial spaces like offices, shops, and hotels.
- Large rooms or areas with big temperature swings (sunrooms, basements).
- Projects where the floor must not shift or gap, e.g., over concrete slabs.
When to Choose WPC
- Residential spaces where comfort underfoot matters more than cost.
- Upper-floor installations where sound insulation is a priority.
- Anywhere a softer, warmer feel is desired.
Installation & Maintenance
Both floors use click-lock installation and can float over most subfloors without glue. Both are 100% waterproof, pet-friendly, and cleaned with a damp mop. No waxing, sanding, or sealing is ever needed.
Frequently Asked Questions
Is SPC or WPC flooring better?
Neither is universally better. SPC wins on stability and price; WPC wins on comfort and sound insulation. Choose based on the room’s use and your budget.
Is SPC flooring really waterproof?
Yes, SPC’s stone-plastic core absorbs no water, so it is fully submersible-proof for normal use, including kitchens, bathrooms, and basements.
Can SPC flooring be used on underfloor heating?
Yes. SPC conducts heat well and is stable under temperature change, making it one of the best flooring choices for underfloor heating systems.
Which is cheaper, SPC or WPC?
SPC is typically 15-30% cheaper than WPC at comparable quality, mainly because the stone-plastic core uses cheaper raw materials.
