What Thickness Underlay Is Best for Laminate Flooring?

Laminate flooring is a popular choice for its durability, affordability, and ease of installation. However, choosing the right underlay for laminate flooring is crucial to ensure a long-lasting and comfortable floor.

The thickness of the underlay plays a significant role in the overall performance and longevity of your laminate flooring. Here are the key considerations to keep in mind when selecting the best underlay thickness:

1. Subfloor Condition

The condition of your subfloor will determine the appropriate underlay thickness. Uneven or damaged subfloors require a thicker underlay (6mm or more) to provide additional support and level out the surface.

2. Foot Traffic

Heavier foot traffic areas, such as entryways or living rooms, require a thicker underlay (3-6mm) to absorb impact and reduce noise. For less-trafficked areas like bedrooms, a thinner underlay (2-3mm) may suffice.

3. Moisture Resistance

In areas prone to moisture, such as kitchens or basements, an underlay with a moisture barrier is essential. Look for underlays with a polyethylene or aluminum vapor barrier to prevent moisture from seeping through the flooring.

Regarding thickness, thicker underlays (4-6mm) provide better moisture protection than thinner ones.

4. Sound Insulation

Laminate flooring can be noisy without proper underlayment. Thicker underlays (4-6mm) offer superior sound insulation, reducing impact noise and improving acoustic comfort.

5. Thermal Insulation

Underlays can also provide thermal insulation, which is especially beneficial for floors installed over cold subfloors. Thicker underlays (3-6mm) with a closed-cell structure provide better thermal resistance.

Recommended Underlay Thicknesses

Based on the above considerations, here are some recommended underlay thicknesses for laminate flooring:

2-3mm: Suitable for bedrooms and other low-traffic areas.

3-6mm: Recommended for most residential applications, including entryways and living rooms.

Over 6mm: Ideal for areas with uneven subfloors, heavy foot traffic, or moisture concerns.

Remember, thicker underlays generally offer better performance but may increase the overall cost. It's important to strike a balance between your needs and budget when selecting the right underlay thickness.
