Understanding SPC and WPC Cores
When shopping for luxury vinyl flooring, you will encounter two main core types: SPC (Stone Plastic Composite) and WPC (Wood Plastic Composite). Understanding the differences helps you make the right choice.
What is SPC Flooring?
SPC flooring features a rigid core made from limestone and PVC:
- Composition: 60-70% limestone, 25-30% PVC, plasticizers
- Thickness: Typically 3.5-7mm total
- Density: Very dense and rigid
SPC Advantages
- Extremely durable and dent-resistant
- Best for commercial applications
- More temperature stable
- Thinner profile for easier transitions
- Generally more affordable
SPC Disadvantages
- Harder underfoot, less comfortable
- Can feel cold without underlayment
- Transmits more sound
What is WPC Flooring?
WPC flooring has a foamed core that provides cushioning:
- Composition: Wood flour, PVC, plasticizers, foaming agents
- Thickness: Typically 5-8mm total
- Density: Less dense due to foam structure
WPC Advantages
- Warmer and softer underfoot
- Better sound absorption
- More comfortable for standing
- Often feels more premium
WPC Disadvantages
- Can dent from heavy furniture
- Less temperature stable in unconditioned spaces
- Usually costs more than SPC
