Resilient Flooring Guide

Product Definition

Herringbone SPC Flooring is a rigid stone-plastic composite flooring solution designed in a herringbone interlocking pattern, offering dimensional stability, water resistance, and enhanced visual aesthetics for commercial and residential environments.

• Fire Rating: Bfl-s1 (EN 13501-1)

Structure & Material Composition

• UV Coating: Surface protection against scratches and chemicals

• Wear Layer: Transparent PVC wear layer resistant to abrasion

• Décor Film: High-resolution printed wood pattern for herringbone aesthetics

• SPC Rigid Core: Limestone + PVC composite for dimensional stability

• Underlay (Optional): IXPE/EVA pad for acoustic and installation performance

Manufacturing Process

1. Raw Material Blending: PVC resin, limestone powder, and stabilizers mixed under controlled temperature.

2. Extrusion: SPC sheets extruded through a twin-screw extruder to ensure uniform density.

3. Lamination: Heat and pressure applied to bond décor film and wear layer.

4. Cooling & Stabilization: Sheets enter a cooling conveyor to regain structural balance.

5. Cutting: Precision cutting machines form herringbone-size planks.

6. Profiling: CNC milling creates angle–tap herringbone locks with ±0.02 mm accuracy.

7. UV Coating: Multi-layer UV coating enhances wear, stain, and chemical resistance.

8. Quality Test: Dimensional stability, peel strength, fire reaction, and surface abrasion tests.

Industry Comparison

Application Scenarios

• Distributors supplying premium flooring ranges

• EPC contractors delivering hotel, office, and retail upgrades

• Commercial developers targeting luxury interior finishes

• Residential renovation projects requiring stable waterproof flooring

• Hospitality: restaurants, boutique hotels, lounges

• Showrooms and high-traffic indoor commercial zones

Core Pain Points & Solutions

• Pattern Misalignment: CNC profiling ensures consistent angle–tap joint geometry.

• Dimensional Deformation: SPC rigid core maintains ≤0.05% expansion under heat.

• Surface Scratching: UV wear coating improves scratch resistance.

• Subfloor Unevenness: Optional IXPE pad increases tolerance to minor irregularities.

Risk Warnings & Mitigation

• Do not install over unstable subfloors; check moisture ≤ 2.0% CM.

• Avoid direct sunlight > 45°C; blinds recommended for large window areas.

• Use transition profiles for large areas exceeding 15 m in length.

• Verify locking mechanism compatibility for herringbone directionality.

Procurement & Selection Guide

1. Confirm thickness and wear layer based on traffic level (0.5–0.7 mm for commercial).

2. Check CNC profiling accuracy for smooth herringbone installation.

3. Verify décor film resolution and synchronous EIR quality.

4. Request EN 13501-1 fire rating and dimensional stability test results.

5. Evaluate underlay option based on acoustic requirements.

6. Inspect locking precision through sample assembly.

7. Review UV coating test data for stain and scratch resistance.

Engineering Case Example

A 3,200 m² boutique hotel renovation selected 5.0 mm Herringbone SPC Flooring with a 0.5 mm wear layer. Installation teams achieved an average efficiency of 150–180 m²/day due to pre-cut herringbone profiles. Dimensional stability testing ensured zero complaints after seasonal humidity shifts, and the acoustic underlay improved room sound insulation by 18–20 dB.

FAQ

• Is Herringbone SPC Flooring fully waterproof? Yes, due to the rigid SPC core.

• Can it be used in hotels? Yes, widely applied in commercial hospitality zones.

• Does herringbone require special installers? Experienced installers recommended for patterned layouts.

• Is underlay necessary? Optional but beneficial for acoustics.

• Can it be installed over tiles? Yes, if leveled properly.

• What is the recommended wear layer? 0.5 mm or above for commercial projects.

• Does it fade under sunlight? UV exposure may cause slight fading; shading advised.

• What is the expected service life? 15–25 years depending on usage.

• Is it scratch-proof? Not scratch-proof, but highly resistant with UV coating.

• Can damaged panels be replaced? Yes, individual plank replacement is possible.
