Why Underlayment Matters for Luxury Vinyl Floors
Underlayment is a thin layer of material installed between your subfloor and flooring. It serves several important purposes:
- Adds cushioning for better comfort underfoot
- Reduces sound between floors, great for upstairs rooms
- It helps with insulation and temperature control.
- Smooths minor subfloor imperfections
- It provides moisture protection, especially over concrete.
For homeowners choosing water-resistant flooring, the proper underlayment helps prevent mold and mildew caused by trapped moisture. Even the most advanced luxury vinyl tile styles need an adequate base to perform at their best.
Do All Luxury Vinyl Floors Need Underlayment?
Not always. Some luxury vinyl floors, especially higher-end planks, come with built-in underlayment. These options are designed for easy installation and include noise reduction and moisture barriers. If your flooring consists of this, adding another layer of underlayment may not be recommended.
However, if your product does not have underlayment or is installed over a hard subfloor like concrete, you’ll likely need a moisture-blocking underlayment for maximum protection and comfort.
Choosing the Right Underlayment
The type of underlayment you need depends on where you’re installing the floor and what you want out of the space. Acoustic underlayments are ideal for quiet bedrooms or second-floor areas, while waterproof underlayments provide added protection for basements or bathrooms.
If you're unsure what works best, your installer can help determine the best fit for your luxury vinyl plank flooring installation.
