7mm SPC Flooring vs 5mm: Which Thickness Should You Choose?

If you’re planning to upgrade your flooring, you’ve probably come across this common confusion:

👉 Should I go for 5mm SPC flooring or 7mm SPC flooring?

At Madeleine Floors, one of the best vinyl plank flooring manufacturers, we hear this question almost every day. And honestly, the answer depends on how and where you plan to use it.

Let’s simplify everything for you in a practical, easy-to-understand way.

1. Introduction: Why Thickness Matters in SPC Flooring

SPC flooring is known for durability, but thickness plays a big role in:

• Strength
  
• Comfort
  
• Sound insulation
  
• Lifespan
  

In India, flooring has to handle:

• Extreme heat (up to 45–50°C)
  
• High humidity
  
• Daily wear & tear
  

That’s why choosing the right thickness is important. A small difference like 5mm vs 7mm can impact performance by 20–30% in real-life usage.

2. What is SPC Flooring? (Quick Overview)

SPC stands for Stone Plastic Composite — a rigid core vinyl flooring made from limestone and PVC.

It consists of:

• UV coating
  
• Wear layer (0.3mm–0.5mm)
  
• Printed design layer
  
• SPC core
  
• Underlayment
  

Compared to traditional flooring:

• 100% waterproof
  
• Termite-proof
  
• Easy installation
  
• Lifespan up to 15–20 years
  

No wonder SPC flooring demand in India is growing at over 12% annually.

3. Understanding SPC Flooring Thickness

What Does 5mm and 7mm Mean?
