How Thick Should Underlayment Be For Laminate Flooring?

When installing laminate flooring, the thickness of the underlayment plays a crucial role in ensuring the longevity and performance of the flooring. Using an underlayment that is too thin or too thick can lead to various problems, such as a spongy feel underfoot, noise issues, or even damage to the flooring itself. Here's an in-depth look at how thick underlayment should be for laminate flooring and the factors to consider when making your choice:

Recommended Thickness Range:

Generally, underlayment for laminate flooring should have a thickness ranging from 2mm (0.079 inches) to 10mm (0.39 inches). This range provides an optimal balance between impact absorption, noise reduction, and support for the flooring.

Factors to Consider:

Subfloor Condition: The condition of the subfloor should influence the thickness of the underlayment. If the subfloor is uneven or has minor imperfections, a thicker underlayment (6mm-10mm) can help smooth out the surface and provide additional support.
Noise Reduction: Thicker underlayments are generally more effective at reducing impact noise and sound transmission. If minimizing noise is a priority, consider using an underlayment with a thickness of 6mm or more.
Moisture Resistance: In areas with potential moisture exposure, such as basements or kitchens, it's advisable to use an underlayment with a moisture barrier. These barriers can help protect the laminate flooring from moisture damage.
Thermal Insulation: Underlayments with a higher R-value provide better thermal insulation. If you live in a cold climate or want to improve energy efficiency, consider using an underlayment with a high R-value.
Laminate Flooring Type: Different types of laminate flooring may require specific underlayment thicknesses. Consult the manufacturer's recommendations for your specific flooring to ensure compatibility.

Additional Tips:

Always use an underlayment that is specifically designed for laminate flooring.
Install the underlayment according to the manufacturer's instructions to ensure proper performance.
If you're unsure about the appropriate thickness for your needs, consult with a flooring professional.

By carefully considering the thickness and other factors outlined above, you can select the right underlayment for your laminate flooring installation. This will not only enhance the performance and longevity of your flooring but also contribute to a more comfortable and enjoyable living environment.
