SPC Flooring with IXPE Backing
SPC Flooring with IXPE Backing Definition
SPC flooring with IXPE backing is a rigid-core vinyl flooring system combining a stone–plastic composite core and an integrated IXPE acoustic layer. It offers dimensionally stable, waterproof, and noise-reducing performance for residential and commercial applications.

Structure & Material Composition
UV Coating: Scratch resistance with anti-stain performance.
Wear Layer: Transparent PVC wear-resistant film.
Decor Film: High-resolution printed wood or stone pattern.
SPC Rigid Core: CaCO₃ + PVC composite for high stability.
IXPE Backing: Cross-linked polyethylene foam for sound reduction and comfort.
Manufacturing Process & Engineering Workflow
Raw material dosing and PVC/CaCO₃ blending.
SPC extrusion through a twin-screw line (continuous extrusion).
Cooling, stabilization, and dimensional conditioning.
Decor film and wear layer lamination using hot-press equipment.
UV coating and surface texturing (EIR, embossed, matte).
CNC profiling to form locking systems with high precision.
Application of IXPE layer using hot-melt lamination.
Final inspection: dimensional tolerance, click strength, curling, stability.
Packing, carton sealing, and palletizing.
Material Comparison
| Flooring Type | Advantages | Limitations | Typical Projects |
|---|---|---|---|
| SPC Flooring with IXPE | Waterproof, rigid core, acoustically improved | Heavier density | Hotels, offices, apartments |
| Laminate Flooring | Cost-effective, scratch-resistant | Not waterproof | Homes, commercial rooms |
| WPC Flooring | Soft underfoot, warm surface | Lower stability | Retail, residential |
Applications in Engineering Projects
Commercial office buildings requiring acoustic performance.
Hotel rooms and corridors with high foot traffic.
Residential apartments requiring waterproof floors.
Shopping malls, retail stores, and hospitality venues.
Educational facilities and healthcare spaces.
Core Pain Points & Engineering Solutions
Noise transmission: IXPE backing reduces sound impact rating by 18–20 dB.
Click-lock failure: CNC profiling ensures tight engagement and minimizes gaps.
Dimensional instability: SPC rigid core maintains low expansion rate even under temperature variance.
Installation difficulty: Integrated IXPE backing eliminates the need for separate underlayment.
Risk Warnings & Mitigation
Avoid installing over uneven substrates; leveling tolerance must be ≤ 2 mm.
Protect from direct sunlight to minimize thermal expansion.
Confirm substrate moisture ≤ 3% to avoid vapor pressure issues.
Use certified click systems to prevent long-term seam separation.
Procurement Selection Guide
Determine required wear layer thickness based on traffic (0.3–0.7 mm).
Check SPC core density and dimensional stability test reports.
Select the IXPE thickness based on acoustic requirements.
Review locking system certification (Unilin / Valinge).
Evaluate surface finish durability through sample testing.
Request batch test reports (formaldehyde, slip resistance, fire rating).
Verify supplier’s extrusion and profiling equipment capabilities.
Engineering Case Example
A 12,000 m² hotel renovation project adopted 5.0 mm SPC flooring with 1.5 mm IXPE backing and 0.5 mm wear layer. The installation achieved 20 dB sound reduction and passed EN ISO 23999 stability tests. After 6 months of operation, the flooring maintained tight seams and uniform acoustics throughout all guest floors.
FAQ
1. What IXPE thickness is recommended? 1.0–1.5 mm for commercial use.
2. Does SPC flooring require separate underlay? Not when IXPE is integrated.
3. Is SPC fully waterproof? Yes, due to the rigid PVC–CaCO₃ core.
4. Can it be installed over tiles? Yes, if the surface is flat.
5. What wear layer is suitable for hotels? 0.5 mm or above.
6. Is the IXPE layer removable? No, it is factory-laminated.
7. Can SPC be used with underfloor heating? Yes, with controlled temperature.
8. What affects click system quality? CNC precision and material stability.
9. What certifications matter? EN ISO standards, FloorScore, CE.
10. Is SPC suitable for heavy commercial traffic? With ≥0.5 mm wear layer, yes.
