Foamed core: warmer, quieter and softer than SPC — and thicker. Typical installed cost, durability, where it works and how to care for it.
WPC stands for wood-plastic composite. It's built the same basic way as SPC vinyl plank — a rigid, waterproof core under a printed wood or stone layer — but the core is a foamed plastic-and-wood-flour blend instead of solid stone powder. That foam is what makes it feel warmer, softer and quieter underfoot than SPC, at the cost of denting more easily under something heavy.
WPC uses a foamed composite core containing wood flour and PVC. The air trapped in that foam makes the plank thicker, lighter, warmer to the touch and noticeably quieter than SPC. It's also more forgiving of small subfloor imperfections, thanks to that same foam.
The tradeoff is indentation resistance: a heavy point load — a refrigerator foot, a piano caster — can leave a permanent dimple. WPC is still fully waterproof, though; the "wood" in it is encapsulated flour, not actual lumber.
Warmer and quieter underfoot than SPC, which matters if the dog sleeps on it, but the foamed core dents more readily under a heavy dog and under furniture. Same wear layer rules apply.

Workable, but the foamed core that makes WPC warmer and quieter underfoot also makes it a worse conductor — the system has to work harder to deliver the same heat SPC would pass through. Manufacturer surface-temperature limit: about 85°F.
Floating click — tools run roughly $150–$400 to buy
A bedroom in a day; a whole floor over a long weekend. Same floating-click job as SPC, with a thicker, softer plank that's slightly more forgiving over minor subfloor irregularity.
Air pockets reduce weight and thermal conductivity. WPC floors feel roughly 5–10 °F warmer to bare feet than SPC over the same slab.
Look for a static load / residual indentation number. WPC typically lags SPC here by a wide margin — the number, not the marketing, tells the story.
WPC with an attached pad commonly reaches IIC 60+ and STC 50+ in tested assemblies, which is why condo boards often accept it where SPC needs added underlayment.
All vinyl moves with temperature. WPC moves more than SPC. Follow expansion-gap requirements exactly and avoid uncontrolled direct sun.

Choose WPC upstairs and in bedrooms for comfort and quiet; choose SPC downstairs and in kitchens for dent resistance. Many homes use both.
Each feature paired with the benefit it delivers. A spec on its own tells you nothing about whether it is worth paying for.
Air pockets make it warmer to bare feet than SPC over the same slab, and noticeably quieter underfoot — the two things people notice first.
Bridges minor subfloor imperfections that would telegraph through a thin rigid plank, cutting floor-prep cost on an older house.
Commonly reaches IIC 60+ and STC 50+, which is what condo boards ask for before they approve hard surface over a neighbor.
Same immunity to water as SPC — the wood content is encapsulated flour, not lumber, so there is nothing for moisture to attack.
Meaningfully more forgiving for standing and for dropped glassware, which matters in kitchens and second-floor bedrooms.
The specifications below decide how this floor performs. Ask for them in writing — a sample board and a price per square foot do not tell you any of it.
Luxury Vinyl Plank — WPC (Wood-Plastic Core) runs $5.00–$13.00 per square foot installed in 2026 — $3.00 to $8.00 for material and $2.00 to $5.00 for professional labor. Spread across an expected 15 to 25 year service life that works out near $0.45 per square foot per year. Regional variation of 20 to 40% is normal, and demolition, subfloor prep and trim are extra.
15 to 25 years, assuming it went into an appropriate room over a properly prepared substrate and gets the maintenance it needs. Choose WPC upstairs and in bedrooms for comfort and quiet; choose SPC downstairs and in kitchens for dent resistance. Many homes use both.
Basement (below grade), Bedroom, Living / Family Room, Home Office. Bedrooms, living rooms and second floors. Homes wanting quieter, warmer waterproof floors.
Sunroom / Four-Season Room. Rooms with very heavy point loads. Commercial and retail traffic.
Yes — WPC vinyl plank is unaffected by water, which is why it works in bathrooms, laundries and below grade. Note that a waterproof material does not make a waterproof floor: water can still travel through seams to the subfloor beneath.
Sweep and damp-mop with pH-neutral cleaner. Use the largest-diameter, softest casters you can on rolling furniture. Critically: never use rubber-backed rugs.
