What is SPC Flooring?
SPC stands for Stone Plastic Composite — a rigid vinyl flooring where the core is made from limestone powder (calcium carbonate) mixed with PVC. The result is a flooring board that is 100% waterproof, dimensionally stable (does not expand/contract with humidity), and far more rigid and dense than standard flexible vinyl. SPC is also marketed as LVP (Luxury Vinyl Plank) with a rigid core, or Hybrid flooring in some markets.
SPC Flooring Structure
| Layer | Material | Function |
|---|---|---|
| Wear layer | Clear PVC (0.2–0.7mm) | Scratch and stain resistance |
| Decorative layer | Printed film | Wood or stone visual |
| SPC core | Limestone + PVC + stabilisers | Rigidity, waterproof performance, dimensional stability |
| Backing layer | IXPE foam or cork (optional) | Acoustic absorption, underfoot comfort |
SPC vs Laminate vs Engineered Wood in India
| Feature | SPC | Laminate | Engineered Wood |
|---|---|---|---|
| Waterproof | Yes (100%) | No (HDF core absorbs water) | Moisture-resistant only |
| Real wood | No | No | Yes (real veneer) |
| Price (material) | ₹95–₹250/sqft | ₹65–₹200/sqft | ₹180–₹450/sqft |
| Best climate | All climates, especially humid | Dry/moderate climates | Moderate/dry climates |
| Subfloor tolerance | High (rigid core bridges minor imperfections) | Low (follows subfloor undulations) | Moderate |
| Warmth underfoot | Moderate (with IXPE backing) | Good (12mm) | Excellent |
SPC Thickness Guide for India
- 4mm SPC: Budget option for low-traffic areas — not recommended for main living areas
- 5mm SPC: Standard residential — suitable for bedrooms, corridors
- 6mm SPC: Recommended standard — living rooms, kitchens, bathrooms, home offices
- 8mm SPC: Premium residential and light commercial — heavy foot traffic areas
Wear Layer — The Most Important Specification
The wear layer thickness determines how long the floor lasts in use. 0.3mm = 12–15 years (light residential). 0.5mm = 20–25 years (heavy residential). 0.7mm = 25+ years (light commercial). Always check the wear layer specification, not just the total board thickness — a 6mm board with 0.2mm wear layer is inferior to a 5mm board with 0.5mm wear layer.
SPC Installation in India
SPC uses click-lock floating installation — no adhesive, no nails. The subfloor must be flat to within 3mm per 3m. The rigid SPC core bridges minor imperfections better than laminate but cannot compensate for significant dips or humps. Use a 1mm moisture barrier underlay if the subfloor is concrete (standard in Indian apartments). Installation is typically 15–25% faster than laminate due to the rigid core's stability.
