SPC Flooring Thickness Guide
Choosing the right SPC flooring thickness is essential for durability, comfort, and long-term performance. SPC (Stone Plastic Composite) flooring is available in different thickness levels, each suited to specific applications such as residential use, high-traffic areas, or commercial spaces. This guide explains SPC flooring thickness options and how to select the best one for your project.
What Does SPC Flooring Thickness Mean?
SPC flooring thickness refers to the total thickness of the plank, including the rigid core, decorative layer, wear layer, and any attached underlay. While thickness alone does not determine quality, it plays an important role in stability, sound absorption, and resistance to impact.
Common SPC Flooring Thickness Options
1. 3.5 mm – 4 mm SPC Flooring
This thinner SPC flooring is lightweight and cost-effective, suitable for low-traffic areas where minimal impact resistance is required.
Best For:
- Bedrooms
- Guest rooms
- Light-use residential spaces
2. 4.5 mm – 5 mm SPC Flooring
Medium-thickness SPC flooring offers improved stability and durability compared to thinner options. It provides a good balance between cost and performance.
Best For:
- Living rooms
- Kitchens
- Apartments and flats
3. 5.5 mm – 6 mm SPC Flooring
This thickness range is popular for residential and light commercial use, offering better impact resistance and improved comfort underfoot.
Best For:
- Open-plan homes
- Hallways and corridors
- Small offices
4. 6.5 mm – 7 mm SPC Flooring
Thicker SPC flooring provides enhanced rigidity, noise reduction, and resistance to heavy foot traffic. It is often chosen for demanding environments.
Best For:
- Commercial spaces
- Retail shops
- High-traffic areas
5. SPC Flooring with Attached Underlay
Some SPC floors include an attached underlay, increasing total thickness while improving sound absorption and comfort. This option helps reduce installation time and enhances overall performance.
Best For:
- Apartments
- Upper floors
- Offices and shared spaces
Does Thicker SPC Flooring Mean Better Quality?
Not always. While thicker SPC flooring can improve comfort and noise control, wear layer thickness and core density are equally important. A thinner SPC plank with a strong wear layer may outperform a thicker plank with lower-quality materials.
How to Choose the Right SPC Flooring Thickness
Traffic Level:
Higher traffic areas require thicker SPC flooring with better impact resistance.
Subfloor Condition:
Slightly uneven subfloors benefit from thicker planks or SPC with underlay.
Sound Requirements:
Apartments and offices may need thicker SPC flooring for noise reduction.
Budget Considerations:
Balance thickness with wear layer quality and long-term durability.
Frequently Asked Questions (FAQ)
1. What is the best SPC flooring thickness for homes?
For most homes, 4.5 mm to 6 mm SPC flooring offers a good balance of durability and comfort.
2. Is thicker SPC flooring more durable?
Thicker SPC can improve stability, but durability mainly depends on the wear layer and core quality.
3. Can thin SPC flooring be used in kitchens?
Yes, as long as it has a waterproof core and adequate wear layer.
4. Is SPC flooring thickness important for installation?
Yes, thickness affects subfloor tolerance, sound absorption, and overall floor feel.
5. Does SPC flooring need underlay?
Some SPC flooring includes built-in underlay, while others may require separate underlay based on project needs.
