SPC, WPC and traditional vinyl plank are all members of the same vinyl family, but the core construction is different in each one — and that core decides how the floor feels underfoot, how it copes with heat, and how forgiving it is on an imperfect subfloor. Here’s the practical breakdown so you can pick the right one for your room.
What all three have in common
Every vinyl plank is built on the same idea: a PVC base layer, a printed photographic decor layer that mimics timber or stone, and a clear wear layer on top. That’s why all three options share the same headline benefits — fully waterproof, low maintenance, scratch-resistant, and a wide range of timber and stone looks. The differences start one layer down, in the core.
The core is what separates them
Traditional vinyl plank has a thin, flexible PVC core. WPC stands for wood plastic composite — a rigid core made of PVC mixed with wood-flour and a foaming agent that adds cushion. SPC stands for stone plastic composite — a rigid core made of PVC mixed with limestone powder, which gives it density and dimensional stability. Same family, three different recipes. If you want the longer comparison between SPC and the broader hybrid category, we’ve covered that in what’s the difference between hybrid and SPC.
Traditional vinyl plank — the budget option
Traditional luxury vinyl plank is the thinnest and most flexible of the three. Most products in this category are glue-down — the plank is bonded directly to the subfloor with adhesive, not floated. That makes the install a bit more involved, and it means any bumps or hollows in your subfloor will telegraph through the surface. Pricing typically lands around $20 to $30 per square metre on the product itself, before underlay and labour.
Where it suits: tight budgets, smaller rooms, level subfloors, and households that don’t mind a softer underfoot feel. Where it struggles: rooms with big temperature swings (it expands and contracts more than the rigid options), and any subfloor that hasn’t been levelled properly.
WPC — the comfort option
WPC’s wood-composite core has a foaming agent baked in, which gives it the most cushion of the three. It’s quieter underfoot, warmer in winter (the wood content holds heat better than stone), and noticeably softer on the legs in rooms you stand in for long stretches — kitchens, home offices. Most WPC products are floating floors with a click-lock joinery system, so they don’t need adhesive and they tolerate small subfloor undulations.
The trade-offs: WPC is generally the most expensive of the three, and the softer core means it dents under heavy point loads more readily than SPC. A dropped cast-iron pan or a stiletto heel will leave a mark.
SPC — the durable, dimensionally stable option
SPC’s limestone-loaded core is denser and more stable than WPC. It’s the hardest of the three to dent, and it barely moves with temperature changes — which matters in Australian rooms with large north-facing windows or non-shaded sliding doors where the floor temperature can swing 20 degrees through the day. SPC is usually a click-lock floating install (5G or 2G systems are the most common — see 5G vs 2G click systems), and many SPC ranges ship with a pre-attached IXPE acoustic underlay. Pricing typically sits around $30 to $50 per square metre.
The trade-off: SPC is hard underfoot. The stone-loaded core conducts heat away rather than holding it, so the floor reads colder in winter than WPC. In an upstairs apartment, the IXPE underlay helps with sound transmission to the room below, but a body-corporate acoustic spec may still demand a thicker underlay on top of that.

Side-by-side: how they compare
- Price. Traditional vinyl is cheapest, SPC sits in the middle, WPC is the most expensive.
- Install. Traditional vinyl is usually glue-down. WPC and SPC are floating click-lock installs.
- Subfloor tolerance. Rigid cores (WPC, SPC) hide more imperfection than traditional vinyl. None of them like undulation outside roughly 3 mm over a 2 m span.
- Comfort. WPC is softest, traditional vinyl is in the middle, SPC is hardest.
- Heat retention. WPC reads warmest, traditional vinyl middle, SPC coldest.
- Sound absorption. WPC absorbs the most, SPC is in the middle, traditional vinyl is the loudest.
- Dent resistance. SPC is hardest, traditional vinyl middle, WPC is the softest.
- Temperature stability. SPC is the most stable, WPC second, traditional vinyl least.
Which one should you pick?
If your priority is the cheapest plank and your subfloor is in good shape, traditional vinyl plank does the job. If you want the most comfortable underfoot and the warmest feel, and you’re not laying it in a sun-drenched room, WPC is worth the premium. If you want the most durable, most stable floor that handles temperature swings and heavy traffic — including kitchens, hallways and rooms with big glazing — SPC is the practical pick for most Australian households.
