Walk any flooring trade show and you will hear SPC, LVT, and WPC used almost interchangeably - and mistakenly. All three are vinyl floors that can look like wood or stone, but they differ in core material, dimensional stability, thickness limits, and price. Choosing the wrong one leads to callbacks, especially in hot or humid markets.
LVT (Luxury Vinyl Tile) is the veteran. It is flexible vinyl - limestone and plasticizers without a rigid core - sold in glue-down planks and tiles. LVT conforms to subfloors, works well over raised-access floors in offices, and is the cheapest to produce in thin gauges. Its weakness: it needs adhesive, a skilled installer, and a very flat subfloor. In floating formats, flexible LVT needs to be at least 5mm and still telegraphs subfloor imperfections.
WPC (Wood Plastic Composite) was the first rigid-core floor. Its core blends wood flour and plastic, giving a warmer, slightly cushioned feel underfoot and excellent sound absorption. WPC is 100% waterproof and forgiving over minor subfloor flaws. The trade-offs: wood fiber makes it slightly less dimensionally stable in extreme heat, it is usually thicker (5-8mm) and pricier per square meter, and very heavy designs can be costlier to ship.
SPC (Stone Plastic Composite) replaces wood fiber with limestone. The result is the densest, most stable core of the three: it does not expand or contract meaningfully even in direct sun, under 28°C floor heating, or in tropical humidity. SPC clicks together without glue, tolerates rolling chairs and retail traffic when specified with a 0.5mm wear layer, and is typically the most affordable rigid-core option - limestone is cheaper than wood fiber. The feel is firmer than WPC, which many commercial buyers actually prefer.
Temperature stability is the decisive factor in many markets. In the Middle East, Southeast Asia, and any container that sits in a hot port, WPC cores can edge-cup; SPC shrugs it off. For projects in Russia and Central Asia with underfloor heating and winter delivery, SPC again handles the thermal cycling better. This is why SPC has taken the dominant share of Chinese rigid-core exports since 2020.
Price ranking, FOB China, as a rule of thumb: glue-down LVT is cheapest in thin gauges (2-3mm), SPC sits in the middle (4mm SPC often undercuts 8mm laminate), and WPC commands a 10-20% premium over comparable SPC. For distributors, SPC offers the best margin-to-risk balance: mid price point, near-zero complaint rate, and one SKU family covers residential and light commercial.
Installation differs mainly by format. Glue-down LVT needs full adhesive and ideally a leveler coat - budget 30-50% more installation labor. WPC and SPC both float on click over a foam underlay in half the time. For DIY-oriented retail markets, click SPC is the clear winner; for commercial glue-down specifications and raised floors, classic LVT still holds its ground.
So which should you stock? If you serve one market with mild climate and premium residential buyers, WPC's softer feel sells. If you serve hot climates, commercial projects, or want one resilient line for everything, SPC is the rational default. Keep thin glue-down LVT only if you bid on office or renovation jobs that specify it. SHUCHAN FLOORING manufactures SPC in 3.5-8mm with wear layers from 0.3 to 0.55mm and can supply WPC skirting to color-match - ask our sales team for sample boxes of each to feel the difference yourself.
