Choosing between 6mm and 8mm SPC flooring is not simply a matter of selecting the thicker plank. For distributors, contractors and commercial project buyers, the correct specification depends on the application, traffic level, wear layer, rigid core structure, attached backing, subfloor condition, target price and transportation cost.

This guide compares 6mm vs 8mm SPC flooring from a B2B procurement perspective. It explains how thickness affects product positioning, cost, packing and project suitability, as well as what buyers should confirm before ordering samples or starting bulk production.

 

Quick Answer: Should Buyers Choose 6mm or 8mm SPC Flooring?

6mm SPC flooring is a practical choice for apartments, hotel guest rooms, offices, retail stores and commercial renovation projects where buyers need to balance product performance, factory cost and container utilization.

8mm SPC flooring may be considered when a project requires a thicker rigid structure, a more substantial walking feel or higher product positioning. It is commonly evaluated for hotels, offices, apartment developments and selected commercial interiors.

However, an 8mm plank is not automatically more wear-resistant than a 6mm plank. Surface durability also depends on the wear layer, UV coating and surface finish. Product stability depends on core quality, dimensional control, click-lock precision and correct installation.

What Does SPC Flooring Thickness Include?

SPC flooring thickness normally refers to the total plank thickness, but manufacturers and suppliers may describe the structure differently. Buyers must confirm whether the stated thickness includes an attached IXPE or EVA backing.

For example, the following products should not be treated as identical specifications:

• 6mm SPC plank without attached backing

• 5mm SPC core with 1mm IXPE backing

• 6mm SPC core with additional IXPE backing

• 8mm total structure including attached backing

The purchase confirmation should record the SPC core thickness, wear layer, backing material and backing thickness separately. This avoids comparing quotations for products with different structures.

6mm vs 8mm SPC Flooring Comparison

When Is 6mm SPC Flooring a Practical Choice?

For many wholesale and commercial flooring programs, 6mm SPC flooring provides a practical balance between product structure, cost and transportation efficiency. It can be manufactured with different wear layers, surface textures and backing options according to the intended application.

Common applications for 6mm waterproof SPC flooring include:

• Hotel guest rooms and serviced apartments

• Residential developments and rental apartments

• Offices and meeting rooms

• Retail stores and showrooms

• Commercial renovation projects

• Distributor stock programs

Buyers should not approve 6mm SPC flooring based on thickness alone. Wear layer, locking accuracy, plank dimensions, core structure, surface finish and subfloor requirements should be evaluated together.

 

When Should Buyers Consider 8mm SPC Flooring?

8mm SPC flooring may be selected when the buyer wants a thicker rigid structure or needs to position the flooring collection above standard stock ranges. Depending on the core and attached backing, it may provide a more substantial walking feel.

Possible applications include:

• Hotel and hospitality projects

• Higher-positioned apartment developments

• Office buildings and commercial interiors

• Projects using larger plank formats

• Distributor collections targeting thicker SPC flooring

Before selecting an 8mm SPC flooring supplier, buyers should request the complete product structure and packing information. Additional thickness increases material consumption and plank weight, which may affect both the factory price and the number of square metres loaded into a container.

 

Does Thicker SPC Flooring Mean Better Durability?

Not necessarily. Total plank thickness and surface durability describe different parts of the flooring specification.

The rigid core influences the plank structure, while the wear layer and surface coating protect the decorative film from traffic, scratches and routine cleaning. A thicker plank with an unsuitable wear layer may not be the correct choice for a busy commercial area.

Commercial buyers should compare:

• Total finished thickness

• Actual SPC core thickness

• Wear layer thickness

• UV coating and surface finish

• Core structure and dimensional stability

• Click-lock profile and machining accuracy

• IXPE or EVA backing specification

• Plank dimensions and production tolerance

How Wear Layer Affects 6mm and 8mm SPC Flooring

The wear layer should be selected according to the expected traffic and maintenance conditions. It should not be assumed that an 8mm plank automatically has a thicker wear layer than a 6mm plank.

Two SPC flooring products can have different total thicknesses but use the same wear layer. Buyers should therefore record total thickness and wear layer as separate items in the quotation and purchase confirmation.

For a commercial flooring project, the supplier should know the application, expected traffic and maintenance requirements before recommending a wear layer. This is more reliable than choosing a product from the thickness number alone.

How IXPE Backing Affects the Comparison

Attached IXPE backing may improve installation convenience, walking comfort and sound control, but backing thickness should not be confused with rigid core thickness.

When requesting SPC flooring with IXPE backing, specify:

• Backing material: IXPE, EVA or another option

• Backing thickness

• Backing density when required

• Backing adhesion requirements

• Whether the quoted total thickness includes the backing

Two suppliers may both quote “6mm SPC flooring,” while one quotation refers to a 6mm core and another refers to a total 6mm structure including backing. Written clarification is necessary before comparing prices.

Subfloor Condition Is Still Important

A thicker SPC plank cannot compensate for every subfloor problem. Excessive unevenness, movement, moisture or contamination may affect the locking joints and installation result.

Before installation, contractors should confirm:

• Subfloor flatness

• Surface strength and cleanliness

• Moisture conditions

• Expansion space requirements

• Door, wall and fixed-object transitions

• Installation instructions for the selected locking system

The product specification and installation conditions should be reviewed together, especially for commercial renovation projects.

Cost and Container Loading Considerations

When the other specifications are equal, 8mm SPC flooring normally requires more core material than 6mm SPC flooring. It may therefore have a higher factory price and higher weight per square metre.

Importers and distributors should compare:

• Factory price per square metre

• Square metres per carton

• Gross and net carton weight

• Cartons and square metres per container

• Export packaging requirements

• Loading plan and shipping terms

• Expected market selling position

A lower unit price does not always produce the lowest total purchasing cost. Buyers should compare equivalent structures and request a complete packing and container-loading sheet.

Recommended Evaluation by Project Type

Bulk Order Specification Checklist

Before asking an SPC flooring manufacturer for a final quotation, provide the following information:

• Required total thickness and core thickness

• Wear layer requirement

• Plank dimensions

• Surface texture or EIR requirement

• Color codes and quantity per color

• Click-lock or installation requirements

• IXPE or EVA backing specification

• Carton and pallet requirements

• Total order quantity or project area

• Destination country and purchasing schedule

If the final structure has not been decided, provide the application, expected traffic, target market and budget range. The manufacturer can then prepare suitable 6mm and 8mm specifications for comparison.

Factory Quality Control Before Shipment

A bulk order should be checked against the approved sample and confirmed purchase specification. Depending on the order, inspection may include thickness measurement, plank dimensions, surface appearance, color consistency, edge condition, click-lock fitting, backing adhesion and packaging checks.

 

Frequently Asked Questions

Is 8mm SPC flooring always better than 6mm SPC flooring?

No. The correct choice depends on the application, wear layer, core structure, backing, locking system, installation conditions and budget. A thicker plank does not automatically provide better surface durability.

Is 6mm SPC flooring suitable for commercial projects?

It can be suitable for offices, hotel rooms, retail spaces and commercial renovation projects when the complete specification and installation conditions meet the project requirements.

Can 8mm SPC flooring be used in high-traffic areas?

It may be used in suitable commercial applications, but total thickness alone is not enough to determine suitability. Buyers should also evaluate the wear layer, surface protection, locking system, subfloor and expected traffic.

Does SPC flooring thickness include IXPE backing?

It depends on the supplier’s product description. Buyers should request the core thickness, backing thickness and total finished thickness separately.

Does thicker SPC flooring provide better sound reduction?

Not automatically. Sound performance is influenced by the complete flooring system, including the backing material, backing thickness, subfloor and installation method. Buyers with specific acoustic requirements should provide the project requirements before ordering.

Which thickness is more suitable for hotel guest rooms?

Both 6mm and 8mm SPC flooring may be considered. The final choice should depend on project positioning, wear layer, backing, walking comfort, room conditions and budget.

Which thickness is more suitable for wholesale distribution?

The answer depends on local demand, target selling price and container cost. Some distributors use 6mm SPC flooring as a main stock specification and offer 8mm products for higher market positioning.

Is 8mm SPC flooring more expensive to ship?

It normally has a higher weight per square metre when compared with an equivalent 6mm structure. This may reduce the square metres loaded into a container, so buyers should request carton weight and container-loading information.

Can a thicker SPC plank solve an uneven subfloor problem?

No. SPC flooring still requires a properly prepared subfloor. Excessive unevenness may stress the locking joints and affect the finished installation, regardless of whether the plank is 6mm or 8mm.

What information is needed for an accurate factory quotation?

Provide the total thickness, core thickness, wear layer, plank size, surface design, backing, quantity, packaging requirements, destination country and expected purchasing schedule.

Should buyers approve a sample before bulk production?

Yes. The approved sample provides a reference for color, texture, dimensions, structure and overall appearance. The confirmed specification should also be recorded in the purchase documentation.
