The acronym soup around modern vinyl flooring confuses many homeowners, and the marketing copy doesn’t always clarify what the different terms actually mean. LVP, LVT, SPC, WPC — these aren’t different brand names but different product constructions with meaningfully different characteristics, costs, and appropriate use cases. Understanding the differences helps both at the buying decision and when evaluating quotes from different providers.
This guide walks through what each acronym actually describes, how the constructions compare in real-world performance, and how to choose between them for your specific application.

The Short Answer
Two of these four acronyms describe a shape and two describe a construction. LVP and LVT are plank-shaped and tile-shaped luxury vinyl. SPC and WPC are the rigid cores that can sit inside either of them. That single distinction resolves most of the confusion in a showroom.
For most Ontario homes the answer is mid-range SPC at 20 mil, stepping to WPC where acoustics or softness underfoot matter more than indentation resistance. The wear-layer half of that decision is narrower than it looks: we stock 20, 22 and 30 mil and nothing thinner.
What All These Acronyms Mean
Four terms do most of the confusing, and two of them are not what people assume:
- LVP — Luxury Vinyl Plank. Vinyl flooring made to look like hardwood, sold in plank-shaped pieces. A shape, not a construction.
- LVT — Luxury Vinyl Tile. The same product family in tile-shaped pieces, usually designed to look like ceramic or stone. Also a shape.
- SPC — Stone-Plastic Composite. A rigid-core construction built on limestone powder and polymer. This one is a construction.
- WPC — Wood-Plastic Composite. The other rigid-core construction, built on wood flour and polymer.
The relationships are what the marketing copy tends to blur. LVP and LVT are the same product family in different shapes — only the visual design and the piece dimensions differ. SPC and WPC are constructions that can be sold as either. And standard flexible LVP and LVT still exist alongside both, particularly at the lower price points, and two products described with the same three letters can perform nothing alike.
The Three Constructions Side by Side
| Construction | Core | Typical thickness | Underfoot and sound | Indentation resistance | Where it sits on price |
|---|---|---|---|---|---|
| Flexible LVP / LVT | Vinyl, no rigid core | 2 to 4 mm | Soft, but transmits substrate hardness directly | Lowest | The cheapest of the three, and most of that market is product we do not stock |
| SPC | Limestone powder and polymer | 5 to 7 mm | Firmest of the three | Highest — the dense mineral core takes point loads | Mid to upper, and most of what we sell |
| WPC | Wood flour and polymer | 6 to 8 mm | Softest of the rigid cores; dampens sound best | Below SPC | Alongside SPC, sometimes a little above it |
Construction shows up in the plank and nowhere in the work: a click-lock floor is laid the same way whichever core is inside it. Across the whole vinyl category, installed runs $4 to $13.50 per square foot — plank, underlayment where the product needs one, and labour — and most of our projects land between $6 and $9. Vinyl Flooring Cost in Ontario sets out what sits outside that figure.
SPC: The Practical Mainstream
SPC is the most popular rigid-core vinyl construction in current Ontario residential applications. The core is a composite of limestone powder and polymer materials, producing a rigid, dimensionally stable, dense product typically 5 to 7 mm thick. The rigidity bridges minor substrate variations gracefully, the dimensional stability handles temperature and humidity variations well, and the dense composite resists indentation from heavy furniture and appliances.
Within SPC, products vary by core thickness, wear layer thickness, integrated underlayment and surface finish. Premium SPC products combine 6 to 7 mm cores with 30-mil wear layers and integrated underlayment with vapour barrier function. These products perform well in nearly any residential application and represent the practical mainstream for modern vinyl plank installations.
WPC, the Softer Core, and Where Flexible Vinyl Still Fits
WPC uses a wood flour and polymer composite core similar to SPC in concept but with slightly different characteristics. The wood-based core is generally slightly thicker (6 to 8 mm), slightly softer underfoot than SPC, and provides somewhat better acoustic dampening. The trade-off is slightly less indentation resistance than SPC and slightly higher cost for equivalent quality.
WPC fits applications where the slightly softer feel and acoustic improvement matter. Bedrooms, home offices, and rooms where comfort underfoot is a priority sometimes warrant WPC over SPC. For most applications, the differences are subtle enough that SPC is usually the practical choice; for specific situations where the WPC advantages matter, the premium is worth it.
The flexible constructions are cheapest and the limitations are real. They show minor substrate imperfections more readily than rigid-core alternatives, they are more vulnerable to dimensional change from temperature and humidity, and they typically carry shorter warranties. They also need a flat substrate, because a 2 mm product bridges nothing.
That leaves them a genuine but narrow place: budget-constrained projects, light-use rooms, and flat subfloors. For anything busier, or over a substrate that is not already flat, the modest premium for a rigid core is the easiest money in the category to justify.
SPC and WPC read almost identically on a specification sheet and feel nothing alike underfoot. Compare the cores in one of our showrooms and the difference settles itself in about a minute — in-home visits on request.
What Actually Drives Durability
Wear layer thickness drives more of the durability difference than the core construction does. The thin end of the market is where the disappointments collect, and it is a large part of why we do not stock it. Across the range we do carry — SPC and WPC at 20 to 30 mil — two products with identical cores and different wear layers are still not the same floor, but the gap between them is a matter of margin rather than of one working and one failing.
Indentation resistance is where the cores themselves diverge. SPC’s dense mineral core takes point loads from heavy appliances and furniture legs better than WPC’s wood composite or a flexible product. Kitchen islands, large refrigerators and heavy gym equipment all argue for SPC on that basis alone.
Worth keeping in view while comparing constructions: the failures we get called out to are rarely about which of these was chosen. A recent condo job — eight hundred square feet of luxury vinyl tile, a year old, seams buckling and sections separating — came down to levelling, transitions, expansion gaps, uncontrolled humidity, and heavy furniture standing on a floating floor. Every one of those would have done the same to any construction on this page.
Which Construction Belongs in Which Room
| Room | Construction | Why |
|---|---|---|
| Kitchens | SPC, thick wear layer | Heavy traffic, dropped items, appliance loads |
| Bathrooms | Either rigid core | Moisture handling; the overall installation matters more than the choice between them |
| Basements | SPC with appropriate underlayment | Substrate variation and moisture |
| Bedrooms | WPC, or SPC for general capability | Acoustics and comfort underfoot |
| Main-floor public rooms | Premium SPC or WPC | Visibility and traffic together |
These are best-fit defaults rather than universal answers, and household preferences, design priorities and budget all shift them. Basements in particular carry conditions the table cannot capture — Best Vinyl Flooring for Basements covers what changes below grade.
Getting the Specification Right
Most Ontario homes land on mid-range to premium SPC through the house, which is where Vinyl Flooring Guide for Ontario Homes starts too, with WPC where comfort or sound matters and flexible LVP in low-use spaces. Working out which:
- Start with the room, not the product. Traffic, moisture, and how flat the subfloor actually is.
- Pick the construction from that. SPC at 20 mil is the default for general residential use.
- Match the wear layer to real traffic. SPC at 30 mil for active families, pets and busy main floors.
- Check the spec against the room one more time. The two wrong answers are commercial-grade in a guest bedroom and entry-level LVP in a busy kitchen, and they cost about the same amount of regret.
Brand matters less here than people expect. Most established manufacturers offer comparable products at comparable specifications, so the decision comes down to construction type, wear layer, and which one you like the look of — in that order.

Frequently Asked Questions
What is SPC vinyl flooring?
Stone Plastic Composite—rigid-core vinyl plank with a stone-and-plastic core. The most popular rigid-core vinyl for Canadian residential applications.
Is SPC or WPC better?
Both are rigid-core vinyl. SPC is harder and more durable; WPC is softer and warmer underfoot. Choose based on whether durability or comfort is the priority.
Should I choose flexible or rigid-core vinyl?
Rigid-core (SPC or WPC) is typically the better choice for most residential applications. Flexible LVP works well in budget-conscious projects and rooms with flat subfloors.
Can rigid-core vinyl install over uneven subfloors?
Better than flexible vinyl, but significant subfloor unevenness still requires correction before any vinyl installation.
