Do I Need Underlayment for Vinyl Plank Flooring

Yes, underlayment is often recommended for vinyl plank flooring to provide additional cushioning, sound absorption, and moisture protection. However, it may not be necessary in all cases. Check manufacturer guidelines and consider your specific installation environment before deciding whether to use underlayment.

To ensure a successful installation and maximize the benefits of vinyl plank flooring, it’s crucial to pay attention to the underlayment. In this article, we’ll explore the importance of underlayment in vinyl plank flooring installations and provide a comprehensive guide to help you choose the right underlayment for your project.

Underlayment refers to the layer of material that is installed beneath the vinyl plank flooring. Its primary purpose is to provide support, cushioning, and stability to the flooring, as well as to address specific issues such as moisture protection and sound insulation. Underlayment materials vary widely, ranging from foam to cork to rubber, each with its own unique properties and benefits.

Benefits of Underlayment for Vinyl Plank Flooring

Provides Cushioning and Comfort Underfoot: Underlayment adds a layer of cushioning between the vinyl planks and the subfloor, creating a softer and more comfortable surface to walk on.

Enhances Sound Insulation: Certain underlayment materials, such as cork and rubber, are excellent at absorbing sound, reducing noise transmission between floors and rooms.

Offers Moisture Protection: In areas prone to moisture, such as basements or bathrooms, underlayment with built-in moisture barriers can help prevent water damage and mold growth by creating a protective barrier between the subfloor and the vinyl planks.

Factors to Consider When Choosing Underlayment

Several factors should be taken into account when selecting underlayment for vinyl plank flooring:

  1. Subfloor Type: The type of subfloor you have (concrete, plywood, or existing flooring) will influence the choice of underlayment material and thickness.
  2. Room Location and Moisture Levels: Consider the moisture levels in the room where the vinyl plank flooring will be installed. High-moisture areas may require underlayment with superior moisture resistance.
  3. Noise Reduction Requirements: If reducing sound transmission is a priority, opt for underlayment materials with excellent sound-dampening properties, such as cork or rubber.
  4. Compatibility with Vinyl Plank Flooring: Ensure that the underlayment material is compatible with the specific type of vinyl plank flooring you’ve chosen, and check the manufacturer’s recommendations for compatibility.

Installation Tips for Underlayment and Vinyl Plank Flooring

Proper installation of underlayment is essential for the success of your vinyl plank flooring project. Here are some tips to ensure a smooth installation process:

  1. Proper Preparation of Subfloor: Clean and level the subfloor before installing underlayment to ensure a flat and stable surface for the vinyl planks.
  2. Installation Methods and Techniques: Follow the manufacturer’s guidelines for installing the underlayment, including the recommended installation method (floating, glued, or nailed) and any specific techniques for securing the underlayment to the subfloor.
  3. Importance of Following Manufacturer Guidelines: Always refer to the manufacturer’s instructions for both the underlayment and vinyl plank flooring to ensure proper installation and warranty compliance.


Can I install vinyl plank flooring without underlayment?

Yes, you can install vinyl plank flooring without underlayment. While underlayment can provide benefits such as cushioning, sound insulation, and moisture protection, it is not always necessary. Vinyl plank flooring is designed to be installed directly over a smooth, flat subfloor, such as plywood or concrete.

However, if you prefer additional comfort underfoot or want to reduce noise transmission, you may choose to install underlayment before laying the vinyl planks. Ultimately, the decision to use underlayment depends on your specific preferences and the conditions of your installation environment.

How thick should underlayment be for vinyl plank flooring?

The thickness of underlayment for vinyl plank flooring typically ranges from 1mm to 3mm. However, the ideal thickness depends on factors such as the condition of the subfloor and the desired level of cushioning.

Thicker underlayment provides more cushioning and can help smooth out minor imperfections in the subfloor, while thinner underlayment may be sufficient for flat surfaces with minimal irregularities.

It’s essential to follow the manufacturer’s recommendations for underlayment thickness to ensure proper installation and optimal performance of the vinyl plank flooring.

Can I use underlayment with radiant floor heating?

Yes, you can use underlayment with radiant floor heating systems. However, it’s crucial to select an underlayment material that is compatible with radiant heat and does not hinder the transfer of heat from the heating elements to the flooring surface.

Look for underlayment products specifically designed for use with radiant floor heating, as they are typically constructed from materials that conduct heat effectively without causing damage to the heating system or compromising the performance of the flooring.

Always follow the manufacturer’s guidelines and recommendations for installing underlayment with radiant floor heating to ensure safety and optimal heating efficiency.
