Introduction: Comparing WPC, SPC, and LVT Flooring
Choosing the right flooring material is crucial for both residential and commercial projects, especially in regions with variable climates and high traffic. Wood-Plastic Composite (WPC), Stone-Plastic Composite (SPC), and Luxury Vinyl Tile (LVT) represent the leading rigid and semi-rigid flooring solutions, each offering a unique balance of durability, comfort, water resistance, and cost.
WPC flooring combines wood-like materials with a foamed PVC core, resulting in a soft, cushioned feel underfoot. It excels in comfort, sound absorption, and warmth, making it ideal for bedrooms, living rooms, and low-traffic residential areas. While fully waterproof, its lower density makes it slightly more susceptible to dents and scratches compared to SPC.
SPC flooring is constructed from a dense stone-plastic composite, with a high calcium carbonate content that provides rigidity and stability. Its superior impact and scratch resistance make it suitable for high-traffic areas, commercial spaces, kitchens, and bathrooms. Though firm underfoot, SPC offers unmatched long-term durability and minimal expansion or warping.
LVT flooring consists mostly of flexible PVC with a semi-rigid structure. It is lightweight, highly versatile, and budget-friendly, with moderate water resistance depending on installation quality. LVT is ideal for cost-sensitive projects or areas requiring design flexibility, but it generally has a shorter lifespan and lower impact resistance compared to WPC and SPC.
Understanding these differences helps architects, designers, and homeowners select the flooring type that best balances comfort, performance, aesthetics, and budget for each project.
Material Composition and Core Structure
WPC (Wood Plastic Composite) Flooring Composition
Core materials: Polyvinyl chloride, calcium carbonate, plasticizers, foaming agents, and wood-like materials. Note that manufacturers often use wood flour or wood-like plasticizers instead of real wood.
Structure: Features an expanded PVC core with foam-injected limestone.
Properties: The foam expansion creates a multilayered construction. The base is about half as dense as rigid SPC. This design gives WPC a softer, lighter feel under your feet.
Real-world impact: The softer core makes WPC more prone to dents. I’ve noticed it’s less stable in size compared to SPC.
SPC (Stone Plastic Composite) Flooring Composition
Core materials: Up to 75% calcium carbonate powder (about 60% is limestone), polyvinyl chloride, and plasticizers.
Structure: Has a thin, dense, and heavy core because of the stone content.
Properties: The concentrated limestone creates a rigid sheet. It’s much denser and harder than WPC.
Real-world impact: The high density makes this product much heavier. Based on my experience, it offers more stability and resists dents better.
LVT (Luxury Vinyl Tile) Flooring Composition
Core materials: Mostly polyvinyl chloride with a small amount of calcium carbonate powder.
Structure: Classified as a semi-rigid or flexible sheet flooring.
Properties: The high vinyl content keeps LVT flexible and resilient. You can even roll it for transport.
Real-world impact: LVT’s core is less dense than SPC. I recommend it for spaces that need a resilient surface because of its flexibility.
Thickness and Density Specifications
Standard Thickness and Density Ranges
WPC Flooring (Wood Plastic Composite)
Thickness: Ranges from 5.5 to 9 mm.
Density: Lower than SPC. The foamed core makes this happen. Exact values vary and are often not listed.
Key trait: Thicker build gives a cushioned feel underfoot.
SPC Flooring (Stone Plastic Composite)
Thickness: Ranges from 3.5 to 8 mm. Most products fall between 4 and 6 mm.
Density: 1.9 to 2.05 g/cm³. This makes it the densest option.
Key trait: Thinner design. Much firmer and heavier than WPC or LVT.
LVT (Luxury Vinyl Tile)
Thickness: Ranges from 2 to 4 mm. Some plank versions reach up to 8 mm.
Density: 1.8 to 1.98 g/cm³.
Key trait: Thin and flexible. Resilient with a softer touch compared to stone or wood composites.
Comparative Specifications Table
| Type | Common Thickness Range | Density (g/cm³) | Core Structure | Underfoot Feel |
|---|---|---|---|---|
| WPC | 5.5 – 9 mm | Lower/Variable | Wood/polymer, foamed core | Softer, cushioned |
| SPC | 3.5 – 8 mm (most are 4-6) | 1.9 – 2.05 | Dense limestone-polymer mix | Firmer, denser |
| LVT | 2 – 4 mm (up to 8 mm LVP) | 1.8 – 1.98 | Flexible PVC core | Soft, flexible |
Durability and Impact Resistance in WPC vs SPC vs LVT Flooring
SPC Flooring: Highest Durability and Impact Resistance
Core Strength: Built with dense limestone composite (up to 75% calcium carbonate). SPC flooring is made for maximum rigidity.
Impact and Dent Resistance: Handles heavy traffic and impacts well. Drop a heavy object? It leaves no mark in most cases.
Lifespan: 20–30 years. This makes it the leader in long-term value.
Scratch Resistance: Superior performance. I recommend it for commercial spaces, malls, and busy offices.
Stability: Resists warping, buckling, or structural changes under stress.
Foot Feel: Hard underfoot. But it provides unmatched durability for high-traffic areas.
Common Thickness: 4–6 mm.
Example: I’ve seen SPC in shopping malls and office buildings. Its dense core withstands rolling carts and dragged furniture. No damage.
WPC Flooring: Moderate Durability, More Comfort
Core Composition: Uses a wood flour/polymer foamed core. This offers both strength and resilience.
Impact Resistance: Moderate level. The softer, cushioned core absorbs some impact. But it dents more than SPC.
Lifespan: 15–25 years in most cases.
Scratch Resistance: Good for homes. Not as tough as SPC though.
Sound Absorption & Comfort: Softer and warmer than SPC. I like it for bedrooms and homes.
Common Thickness: 6–8 mm.
Example: I suggest WPC flooring for living rooms or bedrooms. It gives a warm, comfortable feel. It absorbs sound. Heavy impacts can leave marks though.
LVT Flooring: Lower Durability, Flexible Budget Solution
Core Type: Made from flexible PVC with some calcium carbonate. Much less dense than the others.
Impact Resistance: Lowest among the three. Heavy objects cause dents.
Lifespan: 5–20 years. This depends on wear layer thickness and core quality.
Scratch Resistance: Varies by product. The thicker the wear layer, the better it performs.
Flexibility: Good for moderate-traffic projects on a budget.
Common Thickness: 2–4 mm.
Example: Drop a tool or heavy item on LVT? It will dent the flooring. Extra underlayment can help. But it won’t match SPC or WPC performance.

Water Resistance: WPC vs SPC vs LVT
100% Waterproof Performance: SPC and WPC Compared
SPC (Stone Plastic Composite) and WPC (Wood Plastic Composite) are both 100% waterproof flooring options.
SPC has a dense, rigid stone-plastic composite core. It blocks water. Moisture can’t penetrate or cause swelling. I’ve seen SPC floors submerged for days without damage. This makes SPC perfect for bathrooms, kitchens, basements, or commercial spaces with frequent spills or flooding.
WPC’s core mixes wood-plastic composite with a foaming agent. It delivers comfort and strength. It stays 100% waterproof. The closed-cell core stops water from getting in. WPC has lower density than SPC. But this doesn’t hurt its waterproof power indoors. I recommend WPC for homes that need water protection and a softer feel underfoot.
LVT: High Water Resistance, with Some Limits
LVT (Luxury Vinyl Tile) ranges from water-resistant to waterproof. This varies by product and how you install it.
Many modern LVT products have upgraded waterproof cores. But water can seep between the seams if the floor isn’t installed well. This differs from rigid-core floors. You need proper seam sealing and underlayment in humid or high-risk areas.
Flexible LVT sheet floors work like a waterproof membrane with professional installation. But click-lock or glue-down LVT planks can be weak at the joints.
Summary Table: Water Resistance in SPC, WPC, and LVT
| Flooring Type | Core Material | Waterproof Status | Real-World Water Performance | Dent Resistance |
|---|---|---|---|---|
| SPC | Stone-plastic composite | 100% Waterproof | Excels in kitchens, bathrooms, basements, and commercial use | High |
| WPC | Wood-plastic composite | 100% Waterproof | Reliable in all household wet areas; softer surface | Moderate-High |
| LVT | Flexible PVC/plastics | Water-resistant to Waterproof (varies) | Effective with proper install; seam issues possible | Moderate |
