Best Underlayment for LVT Flooring

Choosing the right underlayment for luxury vinyl tile (LVT) flooring can significantly impact the performance and lifespan of your floors. Underlayment plays a crucial role in providing sound absorption, moisture protection, and overall comfort underfoot.

With various underlayment options available, it’s essential to select one specifically designed for LVT flooring. Some of the most popular choices include the SmartCore Premium LVT Flooring Underlayment and Floorlot Laminate Flooring Underlayment. Considering your unique needs and preferences, these underlayments can enhance the overall performance and feel of your luxury vinyl floors.

Importance of Underlayment

The underlayment plays a crucial role in the installation and performance of Luxury Vinyl Tile (LVT) flooring. It serves a variety of functions, and choosing the right underlayment can enhance the overall performance and comfort of your LVT floor.

One of the primary purposes of underlayment is to provide a smooth and consistent surface for the LVT flooring. This helps to ensure that any imperfections in the subfloor do not telegraph through the vinyl, preventing potential damage and improving the overall appearance of the floor.

Another significant benefit of underlayment is the improved underfoot comfort. A good quality underlayment can offer increased cushioning and support, making it more comfortable to walk and stand on for extended periods of time.

Acoustic performance is another reason to consider using an underlayment with your LVT flooring. Proper underlayment can help dampen sound, reducing the amount of noise transmitted between floors and rooms.

Additionally, underlayments can provide a layer of protection against moisture intrusion. A moisture barrier underlayment can help prevent moisture from penetrating the subfloor and potentially damaging your LVT flooring.

In some cases, installing an underlayment for LVT flooring may also be required to maintain the manufacturer’s warranty. Be sure to consult your flooring manufacturer’s guidelines when selecting an underlayment to ensure compatibility and warranty compliance.

Types of Underlayment for LVT Flooring

Foam Underlayment

Foam underlayment is a popular option for LVT flooring due to its affordability and versatility. It provides excellent noise reduction and thermal insulation, making it suitable for rooms like living rooms and bedrooms. Additionally, it’s also lightweight and easy to install, which makes it a favorite for DIY enthusiasts.

Some foam underlayments come with an included moisture/vapor barrier, ideal for areas with high humidity, such as basements and bathrooms. There are various foam underlayment options available, so be sure to choose one that is specifically designed for LVT flooring for the best results.

Cork Underlayment

Cork underlayment is an eco-friendly option and offers excellent sound absorption, making it ideal for rooms where noise reduction is a priority, such as home offices and entertainment rooms. It’s also a natural insulator, providing added thermal comfort in both warm and cool climates.

One disadvantage of cork underlayment is its higher cost compared to foam underlayments. However, its durability and environmentally-friendly properties make it worth considering for LVT flooring installations, especially in high-traffic areas.

Rubber Underlayment

Rubber underlayment is a resilient and durable option for LVT flooring with exceptional sound-dampening properties. This makes it an excellent choice for areas where impact noise reduction is important, such as fitness rooms or playrooms. It also offers thermal insulation, adding an extra layer of comfort underfoot.

While rubber underlayment can be more expensive than foam underlayment, its durability, and enhanced soundproofing capabilities make it a worthwhile investment for specific rooms and applications.

Felt Underlayment

Felt underlayment is a dense, fibrous material known for its superior sound absorption and excellent cushioning. Its thickness and density make it perfect for rooms that require added comfort, such as bedrooms and living spaces. Furthermore, felt underlayment can help smooth out minor subfloor imperfections, ensuring a stable and level surface for LVT installation.

Despite its higher cost compared to other underlayment options, felt underlayment’s longevity and effective sound reduction make it a popular choice for LVT flooring in residential and commercial settings.

Factors to Consider When Choosing Underlayment

When selecting the best underlayment for LVT flooring, there are a few key factors to keep in mind. The right choice will depend on your specific needs and the type of flooring being installed. In this section, we will examine the following sub-factors:


Underlayment thickness can greatly impact the performance and longevity of your LVT flooring. Thicker underlayments tend to offer better sound absorption, insulation, and cushioning, while thinner options may be more suitable for installations with limited height clearance. Consider the specific requirements of your flooring project before deciding on the ideal thickness for your underlayment.

Sound Absorption

Sound absorption is an important consideration for many homeowners, especially those living in multi-level homes or apartment units. Many underlayments, including the Premium LVT Underlayment, have a high Impact Insulation Class (IIC) rating, which measures the ability of the underlayment to absorb and reduce sound transmission.

Moisture Resistance

For LVT flooring installations in areas that may be prone to moisture, such as basements or kitchens, moisture resistance is a crucial factor. Look for underlayments that provide a moisture barrier, such as those made from dense, flexible foam. These materials can help safeguard against mildew, mold growth, and water damage.


Underlayments with good heat insulation properties are especially important when installing LVT flooring over concrete subfloors. Insulation not only provides added comfort by regulating temperature but can also save on heating and cooling costs in the long run.


Prioritize underlayments that are specifically designed for LVT flooring, as these products will be engineered to provide the best performance and protection for your investment. It’s also essential to consider the type of LVT installation you have, whether it be floating or glue-down, as this can impact the kind of underlayment best suited for the job.
