What Thickness Underlay is Best for Laminate Flooring?

Choosing the right thickness of underlay for laminate flooring is an important consideration when installing a new floor. Underlay not only provides support and insulation but also helps to reduce noise and smooth out imperfections in the subfloor. The ideal thickness of underlay for laminate flooring can vary depending on several factors, including the type of subfloor, the specific laminate product, and the desired comfort level.

What thickness underlay is best for laminate flooring?

Here are some guidelines to help you determine the best thickness of underlay for your laminate flooring:

1. Subfloor Type:

- If you have a concrete subfloor, it's generally recommended to use thicker underlay, as concrete tends to be less forgiving and can transmit more cold and noise. A thickness of 3mm to 5mm or more is suitable for concrete subfloors.

- For wood subfloors, which are generally more forgiving and have some natural insulation properties, you can use a thinner underlay. A thickness of 2mm to 3mm is usually sufficient for wood subfloors.

2. Laminate Product:

- Check the manufacturer's recommendations for the laminate flooring you've chosen. Some laminate products may come with specific underlay thickness requirements to maintain their warranty.

- Higher-quality laminate flooring may be more forgiving of thinner underlay, while lower-quality laminates may benefit from thicker underlay to compensate for their lower density and rigidity.

3. Comfort and Noise Reduction:

- Thicker underlay provides better cushioning underfoot, making it more comfortable to walk on. If comfort is a priority, consider using thicker underlay, especially in areas where you'll be standing for extended periods.

- If noise reduction is a concern, thicker underlay can also help dampen sound transmission. This is particularly important in multi-story homes or apartments.

4. Subfloor Imperfections:

- Thicker underlay can help smooth out minor imperfections in the subfloor, providing a more even surface for the laminate flooring. If your subfloor has significant irregularities, a thicker underlay may be necessary to create a level base.

5. Climate Considerations:

- In areas with extreme temperature fluctuations or high humidity levels, thicker underlay can provide better insulation and protection for your laminate flooring.

In summary, there is no one-size-fits-all answer to the question of the best underlay thickness for laminate flooring. It depends on various factors, including the type of subfloor, the specific laminate product, and your personal preferences for comfort and noise reduction. It's essential to consult the manufacturer's recommendations and consider your unique circumstances when selecting the appropriate underlay thickness for your laminate flooring project.
