What is the Minimum Thickness Required for an Underlayment for 3/4 Hardwood Flooring?
When it comes to installing 3/4 hardwood flooring, having the right underlayment is crucial for a successful and long-lasting project. But what’s the minimum thickness required for this type of flooring?
What is Underlayment?
Before diving into the thickness requirement, let’s quickly define what underlayment is. An underlayment is a layer of material installed between the subfloor and the hardwood flooring. Its primary role is to provide a smooth, even surface for the flooring to sit on, as well as to absorb sound and reduce noise.
Minimum Thickness Requirements
According to various hardwood flooring manufacturers and installation experts, the minimum thickness required for underlayment for 3/4 hardwood flooring is typically:
- 1/4 inch (6 mm) for solid hardwood flooring
- 1/8 inch (3 mm) for engineered hardwood flooring
Keep in mind that these are general guidelines and may vary depending on the specific manufacturer’s recommendations and the subfloor’s condition.
Why This Thickness is Important
- It allows for proper expansion and contraction of the hardwood flooring without buckling or warping
- It provides a smooth, even surface for the flooring to sit on, reducing the risk of unevenness and defects
- It helps to absorb sound and reduce noise, making the flooring more comfortable and quieter
Additional Tips
- Look for underlayments with a high density and low moisture content to ensure they won’t absorb moisture from the subfloor or atmosphere
- Choose underlayments with a smooth, even surface to prevent defects in the flooring
- Check the underlayment’s compressive strength to ensure it can support the weight of the flooring and any additional load
