SPC vinyl plank (Stone Plastic Composite) is a 100% waterproof rigid-core flooring made from a dense blend of limestone powder, polyvinyl chloride, and stabilizers. Its stone-based core does not absorb moisture, expand, or warp under humidity, making it the technically correct choice for Florida’s year-round humid climate. At Rios Floor in Orlando, SPC vinyl starts at $1.29/sqft with no minimum order and same-day pickup available.

What Is SPC Flooring?
SPC stands for Stone Plastic Composite. It is a type of rigid-core vinyl flooring engineered around a dense mixture of natural limestone powder, polyvinyl chloride (PVC), and chemical stabilizers. According to ASTM F3261, the standard specification for rigid core luxury vinyl flooring, SPC cores achieve a minimum density of 1.95 g/cm³, significantly denser than flexible LVP or WPC cores. That density is the technical reason the core is inorganic, dimensionally stable, and physically incapable of absorbing moisture.
SPC is not the same as older vinyl flooring or laminate. It belongs to a distinct product category developed to solve the performance problems that wood-based and flexible vinyl floors have in humid, high-traffic environments. The result is a plank that floats over the subfloor on a click-lock system, installs without adhesive, and performs without acclimation, even in Florida’s year-round humidity.

Technical Summary
SPC is defined by a rigid limestone-based core with minimum density of 1.95 g/cm³ per ASTM F3261. The limestone content (65 to 75% by weight) makes the core inorganic and dimensionally stable, producing a maximum of 0.05% dimensional change under humidity variation per ASTM F1914. No wood-based material achieves this stability under Florida’s operating humidity range.
The 5 Layers of an SPC Plank Explained
An SPC plank is a multi-layer engineered product. Each layer has a specific function. Understanding the layers explains why SPC outperforms flexible vinyl and laminate in demanding environments like Florida kitchens and bathrooms.
Section Summary
A 5-layer SPC plank is a precision-engineered product. The wear layer controls surface longevity. The UV coating controls color stability. The EIR design layer controls visual realism. The SPC rigid core controls dimensional stability and waterproofing. The IXPE pad controls acoustic performance. Each layer serves a distinct function and can be evaluated independently when comparing products.
Why SPC Vinyl Was Built for Florida’s Climate
According to NOAA data compiled by the Florida Climate Center (Florida State University), Orlando’s average annual relative humidity is 74%, with peak humidity reaching 79% in August. The Florida Climate Center confirms that morning humidity readings in Central Florida regularly exceed 90% during summer months. NOAA’s 2022 State Climate Summary classifies Florida as the most humid state in the continental United States.
Wood-based materials, including solid hardwood, engineered hardwood, and laminate, absorb and release moisture as humidity fluctuates. That process, called wood movement, produces cupping (edges rising above center), crowning (center rising above edges), and gap formation between boards. In Florida’s climate, it is not a rare event. It is a seasonal cycle that repeats until the floor fails structurally.
SPC vinyl’s limestone-based core is inorganic. Calcium carbonate (CaCO₃) does not participate in moisture absorption at the molecular level. The ASTM F1914 test for dimensional stability measures a maximum of 0.05% change under the conditions governing SPC performance. Solid hardwood, by comparison, exhibits 1% to 3% dimensional change under the same humidity range, according to National Wood Flooring Association (NWFA) technical guidelines.
Florida Climate Data: Orlando
Average annual humidity: 74% | August peak: 79% | Morning summer readings: above 90%
SPC dimensional change: up to 0.05% (ASTM F1914) | Solid hardwood: 1% to 3% (NWFA)

12 Mil vs 20 Mil Wear Layer: Which One Do You Need?
The wear layer is the single most important spec on any SPC plank. It determines how long the floor’s surface resists scratches, scuffs, and visible wear under real-use conditions. The number is measured in mils, where one mil equals one thousandth of an inch. A 12 mil wear layer is 0.30mm. A 20 mil wear layer is 0.50mm. That 0.20mm difference represents the threshold between standard residential and commercial-grade classification per the Resilient Floor Covering Institute (RFCI) wear layer performance standards.
Price premium for 20 mil over 12 mil: $0.40 to $0.80/sqft. Classification reference: Resilient Floor Covering Institute (RFCI) wear layer performance standards.
Section Summary
The wear layer does not affect waterproofing. That is a function of the SPC core. The wear layer controls surface durability only. For most Florida homes, 20 mil is the correct default specification. The $0.40 to $0.80/sqft premium is consistently recovered through extended surface longevity in Florida’s demanding residential conditions.
SPC vs LVP vs WPC vs Laminate vs Hardwood
SPC is frequently confused with LVP and WPC because all three are vinyl-based flooring options sold in plank format. The differences are structural and traceable to core composition. Each category has specific performance characteristics under Florida’s humidity conditions that determine long-term suitability.
| Category | SPC Vinyl | LVP (Flexible) | WPC Vinyl | Laminate | Hardwood |
|---|---|---|---|---|---|
| Core material | Limestone (CaCO₃) + PVC | Flexible PVC | Wood polymer + foam | HDF (wood fiber) | Solid wood |
| Core density | 1.95+ g/cm³ (ASTM F3261) | Below 1.5 g/cm³ | 0.6 to 1.0 g/cm³ | 0.8 to 0.9 g/cm³ | 0.5 to 0.9 g/cm³ |
| 100% waterproof | Yes | Surface only | Yes | No | No |
| Dimensional change (humidity) | Max 0.05% (ASTM F1914) | 0.1 to 0.3% | 0.05 to 0.1% | 0.5 to 1.5% | 1 to 3% (NWFA) |
| Florida humidity | Recommended | Use with caution | Acceptable | Not recommended | Not recommended |
| Price range (material) | $1.29 to $4.50/sqft | $1.00 to $3.50/sqft | $2.00 to $5.00/sqft | $1.50 to $3.50/sqft | $5.00 to $14.00/sqft |
| Lifespan in FL climate | 20 to 30 years (20 mil) | 10 to 15 years | 15 to 25 years | 3 to 5 years | 8 to 15 years |

SPC vs WPC — The Core Distinction
WPC uses a foamed wood-polymer core (0.6 to 1.0 g/cm³) that is softer and warmer underfoot than SPC’s dense limestone core (1.95+ g/cm³). Both are 100% waterproof. SPC’s higher density makes it more dent-resistant and better suited for kitchens, rental properties, and pet households. WPC is preferred where underfoot comfort is the priority over maximum surface hardness.

Frequently Asked Questions
SPC stands for Stone Plastic Composite (also called Stone Polymer Composite). It refers to the rigid core layer made from a dense blend of natural limestone powder (calcium carbonate, CaCO₃), polyvinyl chloride (PVC), and stabilizers. Per ASTM F3261, the standard specification for rigid core luxury vinyl flooring, the SPC core achieves a minimum density of 1.95 g/cm³. This core is what differentiates SPC from older flexible LVP and from WPC (Wood Plastic Composite), which uses a foamed wood-polymer core instead.
Yes. According to NOAA data cited by the Florida Climate Center (Florida State University), Orlando’s average annual relative humidity is 74%, with summer morning readings regularly exceeding 90%. Under these conditions, SPC vinyl shows a maximum 0.05% dimensional change per ASTM F1914, compared to 1% to 3% for solid hardwood per NWFA technical guidelines. SPC requires no acclimation period and can be installed the same day material is picked up from the warehouse.
The wear layer thickness. 12 mil (0.30mm) is the standard residential classification per RFCI wear layer performance standards, appropriate for bedrooms and low-to-moderate traffic areas. 20 mil (0.50mm) is the commercial-grade threshold, recommended for kitchens, bathrooms, rental properties, households with pets, and any space with sustained heavy traffic. The price premium for 20 mil over 12 mil is $0.40 to $0.80/sqft. Note: the wear layer does not affect waterproofing. Waterproofing is a function of the SPC core, not the wear layer.
At Rios Floor, SPC vinyl starts at $1.29/sqft at wholesale pricing, available to homeowners and contractors at the same rate with no minimum order. The full 2026 collection ranges from $1.29 to approximately $4.50/sqft depending on wear layer specification and format.

Yes. SPC vinyl is 100% waterproof through its full core thickness and performs reliably in bathroom applications. One installation requirement: because SPC is a floating floor that does not bond to the subfloor with adhesive, all perimeter edges, toilet bases, and shower thresholds must be sealed with silicone to prevent water from migrating under the planks over time. This is a standard requirement for any floating floor installation in wet areas, not specific to SPC vinyl.
