A Better Flooring Foundation for Melbourne Homes
Laminate flooring has become a favourite among Melbourne homeowners for its durability, stylish finishes, and cost-effectiveness. But one essential question always comes up during installation: Do laminate floors need underlayment? For Dex Flooring customers across Melbourne suburbs such as Nunawading, Surrey Hills, and Doncaster, the right underlay can transform the feel, sound, and lifespan of Laminate Flooring. This guide explains everything you need to know.
What Is Underlayment and Why Does It Matter?
Underlayment is a thin supportive layer installed between the laminate planks and the subfloor. Though subtle in appearance, it makes a significant difference in comfort, sound, moisture protection, and long-term performance.
Does Laminate Flooring Need Underlay?
For nearly all laminate products, the answer is yes. Unless laminate has a factory-attached backing, an additional underlay is essential. Homes in eastern Melbourne, especially in older areas, often require moisture protection in addition to comfort enhancement.

Key Benefits of Laminate Underlayment
Enhanced Comfort
Underlay softens footsteps and creates a smoother walking experience.
Better Acoustic Performance
Reduces hollow sounds, echo, and impact noise—especially useful in multi-level homes.
Protects Flooring From Subfloor Imperfections
Creates a more even surface for laminate boards.
Helps Extend the Flooring’s Lifespan
Minimises friction and prevents unnecessary movement.
Moisture Protection & Vapour Barriers
Melbourne homes with concrete slabs benefit greatly from vapour barriers. Without moisture protection, laminate is prone to swelling, softness, and structural damage.
Best Underlayment Types for Dex Flooring Customers
Different spaces require different underlay solutions. Popular options include:
Standard Foam Underlay
A simple, affordable option suitable for general living areas.
Acoustic Underlay
Ideal for bedrooms, hallways, and multi-storey homes.
Moisture-Barrier Underlay
Essential for concrete floors or rooms near moisture sources.
Premium Felt or Rubber Underlay
Offers superior cushioning and longevity.
Timber vs Concrete Subfloors: What’s the Difference?
Concrete Subfloors
- Always require vapour barrier
- Work best with moisture-resistant underlay
Timber Subfloors
- Provide natural insulation
- Acoustic underlays perform extremely well
Laminate Flooring With Pre-Attached Underlay
Some laminate boards include integrated backing, but this does not replace the need for a moisture barrier on concrete surfaces. Additional acoustic layers may still be recommended.
Consequences of Skipping Underlayment
If underlayment is not used, homeowners may experience:
- Hollow or loud footsteps
- Flooring movement
- Moisture-related damage
- Reduced insulation and comfort
- Faster wear in busy areas
