How to Choose the Right SPC Flooring for Your Project

Picking SPC flooring isn't complicated — but the wrong combination of thickness and wear layer will cost you in callbacks. Here's the contractor's shortcut to a spec that lasts.

Key Takeaways
  • Thickness: 5mm minimum for living areas; 5.5mm+ for sound and feel.
  • Wear layer: 12mil for light residential, 20mil for high-traffic, 28mil+ for rentals or commercial.
  • Underlayment: Look for attached IXPE — it adds sound deadening and moisture protection.
  • Subfloor: Flat within 3/16" per 10' span. Skip this step and you'll feel it underfoot.

What is SPC flooring?

SPC stands for Stone Polymer Composite. It's rigid-core vinyl built around a limestone-PVC core that resists dents, shrugs off water, and stays dimensionally stable through seasonal temperature swings.

For contractors, the appeal is simple: fast click-lock installation, low maintenance, premium aesthetics, and a price point that lands well below engineered hardwood at project quantities.

Picking thickness and wear layer

These are the two specs that matter most. Use the table below as a starting point — then confirm with the manufacturer.

Application Total Thickness Wear Layer
Bedrooms, light residential5mm12mil
Living areas, kitchens5mm - 5.5mm20mil
Entryways, multi-family corridors5.5mm - 6.5mm20mil
Rentals, light commercial6mm+28mil+
Our default spec For residential and multi-family work, we recommend 5mm SPC with a 20mil wear layer and attached IXPE underlayment. It's the durability-to-cost sweet spot, and it's the spec we hold across every SKU in the DURAPLEX line.

Installation best practices

SPC floats over the subfloor with a click-lock system — no glue, no nails, no specialty tools. The install is fast, but a few details separate a clean job from a callback.

  1. Acclimate the product — let planks sit in the installation space for at least 48 hours. SPC is dimensionally stable, but acclimation still matters.
  2. Prep the subfloor — flat within 3/16 inch over a 10-foot span. Fill the low spots, grind the high spots.
  3. Leave expansion gaps — 1/4 inch around all walls and fixed objects. SPC moves less than other vinyl, but proper gapping still prevents buckling.
  4. Use the right underlayment — attached IXPE pads are ideal. If your product doesn't include one, add a 1mm-1.5mm underlayment. Never use thick carpet padding.
