What Thickness Is Best for Hardwood Flooring?
Choosing hardwood flooring involves more than just picking the right colour or timber species. One of the most important—but often overlooked factors is floorboard thickness. The thickness of your hardwood flooring directly affects its durability, stability, lifespan, and overall performance.
For homeowners and builders in Melbourne, selecting the right thickness is especially important due to changing weather conditions and varying subfloor types. The experts at Melbourne Timber Supplies explain what thickness is best for hardwood flooring and how to choose the right option for your project.
Why Thickness Matters in Hardwood Flooring?
Hardwood flooring thickness plays a key role in how the floor performs over time. Thicker boards generally offer better durability and can withstand more wear, while thinner boards may be more cost-effective and suitable for certain applications.
Key Factors Affected by Thickness:
- Strength and durability
- Ability to be sanded and refinished
- Resistance to wear and damage
- Installation method compatibility
Understanding these factors helps you make an informed decision when choosing hardwood flooring.
Common Hardwood Flooring Thickness Options
Hardwood flooring is typically available in a range of thicknesses, depending on whether it is solid timber or engineered wood.
1. Solid Hardwood Flooring
Solid hardwood is usually available in the following thicknesses:
- 12mm (½ inch) – Less common, suitable for lighter use
- 14mm–15mm – Standard thickness for residential flooring
- 18mm–20mm – Premium thickness for maximum durability
Benefits of Thicker Solid Hardwood:
- Can be sanded and refinished multiple times
- Longer lifespan (20–40+ years)
- Better resistance to heavy foot traffic
2. Engineered Hardwood Flooring
Engineered timber consists of a real hardwood top layer over a plywood or composite base. Thickness varies depending on the product.
Typical options include:
- 10mm–12mm – Suitable for apartments or light use
- 14mm–15mm – Balanced option for most homes
- 18mm+ – High-end engineered flooring
The thickness of the top veneer layer is especially important, as it determines how many times the floor can be refinished.
What Thickness Is Best for Different Applications?
Choosing the right thickness depends on how and where the flooring will be used.
Residential Living Areas
For most homes in Melbourne, 14mm–15mm hardwood flooring is ideal. It offers a good balance between durability, cost, and ease of installation.
High-Traffic Areas
For areas like hallways, living rooms, and kitchens, thicker boards (18mm–20mm) provide better resistance to wear and damage.
Apartments and Renovations
Thinner engineered boards (10mm–12mm) are often preferred where height restrictions or existing flooring levels need to be considered.
Commercial Spaces
For commercial applications, thicker hardwood flooring is recommended to handle heavy foot traffic and maintain long-term performance.
How Melbourne’s Climate Affects Flooring Thickness?
Melbourne’s climate can fluctuate between hot, dry summers and cooler, more humid winters. These changes can cause timber to expand and contract.
Why Thickness Matters:
- Thicker boards are generally more stable
- Proper installation reduces movement issues
- Engineered flooring can offer added stability in changing conditions
Choosing the right thickness, combined with proper installation, ensures your flooring performs well throughout the year.
Subfloor Considerations
The type of subfloor also influences the ideal thickness of hardwood flooring.
Common Subfloors:
- Concrete: Often paired with engineered timber or glue-down installation
- Timber/Plywood: Suitable for nail-down installation with thicker boards
Thicker boards provide better structural support, especially when installed over timber subfloors.
Impact on Installation Methods
Floor thickness can determine the installation method used.
Installation Options:
- Nail-down: Best for thicker solid hardwood
- Glue-down: Suitable for both solid and engineered boards
- Floating floors: Typically used for engineered timber
Selecting the correct thickness ensures compatibility with your chosen installation method.
Longevity and Refinishing
One of the biggest advantages of thicker hardwood flooring is its ability to be refinished multiple times.
Benefits:
- Extends the lifespan of the floor
- Allows removal of scratches and wear
- Maintains a fresh appearance over time
Thicker boards are a better long-term investment, especially for homeowners planning to stay in their property for many years.
Cost vs Value
Thicker hardwood flooring generally comes at a higher upfront cost. However, it offers greater durability and longevity, making it more cost-effective over time.
Consider:
- Initial budget
- Expected lifespan
- Maintenance requirements
- Property value impact
For many homeowners, investing in slightly thicker flooring provides better value in the long run.
Choosing the Right Thickness for Your Home
When selecting hardwood flooring, consider the following:
- Room usage and traffic levels
- Subfloor type
- Budget and long-term goals
- Environmental conditions
