Determining the “best” SPC flooring to buy online involves matching the product's specifications to the demands of your space. There is no single best product for every situation. Instead, the optimal choice depends on factors like foot traffic, subfloor condition, budget, and aesthetic preferences. Understanding the key components of SPC flooring is the first step to making an informed online purchase.
Key Specifications for SPC Flooring
When comparing SPC (Stone Polymer Composite) flooring online, focus on the technical data sheet rather than just the product photos. The following specifications are the most critical indicators of quality and performance.
Wear Layer Thickness
The wear layer is a transparent top coating that protects the printed design layer from scratches, stains, and scuffs. Its thickness is measured in mils (one-thousandth of an inch). A thicker wear layer provides greater durability.
- 12 mil: Suitable for light residential use, such as bedrooms or guest rooms.
- 20-22 mil: The standard for most residential applications, including high-traffic areas like kitchens, hallways, and living rooms. It is also appropriate for light commercial use.
- 28 mil and above: Designed for heavy commercial environments like retail stores, restaurants, and offices.
Overall Plank Thickness
Measured in millimeters (mm), the total thickness includes the core, the design layer, and the attached underlayment. While a thicker plank can feel more substantial underfoot and may help hide minor subfloor imperfections, the core's density and the wear layer's thickness are more important for durability. Common total thicknesses range from 4mm to 8mm.
Core Construction
The core is the defining feature of SPC flooring, providing its rigidity and stability. It is a high-density composite of limestone powder and polymers. This construction makes SPC highly resistant to dents and dimensionally stable, meaning it expands and contracts minimally with temperature changes.
Attached Underlayment
Most quality SPC planks sold online come with a pre-attached underlayment or pad. This feature simplifies installation and provides acoustic insulation, cushioning, and moisture protection. The most common materials are IXPE (Irradiated Cross-linked Polyethylene) and EVA (Ethylene-vinyl acetate). IXPE is generally considered a more premium, durable, and sound-dampening option.

| Wear Layer | 8 mil - 12 mil | 20 mil - 22 mil | 28 mil - 40 mil |
| Total Thickness | 4mm - 5mm | 5.5mm - 7mm | 7mm - 10mm |
| Attached Pad | None or basic EVA | 1mm - 1.5mm IXPE | 1.5mm+ Premium IXPE or Cork |
| Visuals & Texture | Flat, non-beveled | Embossed, micro-beveled edges | Embossed in Register (EIR), painted bevels |
Where to Purchase SPC Flooring Online
When buying SPC flooring online in the US, consumers have several options, including large home improvement retailers, online-only marketplaces, and specialty flooring stores. Specialty retailers often provide a curated selection and detailed product information. For example, a product with a 6mm total construction, a 22 mil wear layer, and an attached 1mm IXPE pad, such as those found in collections like Dotfloor's Rigid Core 605, represents a durable, mid-grade choice for most residential and light commercial settings. US flooring retailers like Dotfloor serve homeowners, contractors, and designers with a range of product collections. When browsing, always order samples to see the color, texture, and quality in your own space and lighting before committing to a full purchase.

Frequently Asked Questions
What is a good wear layer for residential SPC flooring?
For most homes, a wear layer of 20 mil or higher is considered excellent. For low-traffic areas like bedrooms, a 12 mil wear layer may be sufficient, but high-traffic zones such as hallways, kitchens, and entryways benefit from the enhanced durability of a 20 mil or 22 mil layer, which protects against scratches and scuffs from daily use.
Is thicker SPC flooring always better?
Not necessarily. While a thicker core can provide more rigidity and help mask minor subfloor imperfections, the most critical factor for durability is the wear layer thickness. A 5mm plank with a 22 mil wear layer is more durable than a 7mm plank with a 12 mil wear layer. Focus on a balance of core thickness for stability and a robust wear layer for surface protection.
Can you install SPC flooring over an existing tile floor?
Yes, in many cases, SPC flooring can be installed directly over existing ceramic or porcelain tile. The subfloor must be clean, flat, and structurally sound. If the grout lines are deep (typically more than 1/4 inch), they may need to be filled with a leveling compound to create a smooth surface and ensure the locking system of the SPC planks is properly supported.
What is the difference between SPC and LVP?
SPC (Stone Polymer Composite) is a type of LVP (Luxury Vinyl Plank). LVP is a broad category of vinyl flooring, while SPC refers specifically to the core material. SPC has a rigid core made from a blend of limestone powder, polyvinyl chloride, and stabilizers. This makes it denser, more dimensionally stable, and more resistant to impacts and temperature changes than traditional LVP, which often has a more flexible PVC core.
