Do You Need an Underlayment for Vinyl Plank Flooring?

An underlayment is recommended for vinyl plank flooring as it provides several benefits. It helps smooth out subfloor imperfections, adds cushioning for comfort, reduces noise transmission, and protects against moisture damage. 

While not strictly required, an underlayment enhances the performance and longevity of vinyl plank floors, making it a worthwhile addition.

Understanding Vinyl Plank Flooring

Vinyl plank flooring is a modern and popular flooring option that combines the aesthetic appeal of hardwood with exceptional durability and moisture resistance. 

It typically features a rigid core made of either wood-plastic composite (WPC) or stone-plastic composite (SPC) – a printed decorative film that mimics wood or stone patterns, and a protective wear layer to safeguard the surface.

Installation methods include click-lock systems for floating installations. There are also glue-down methods to ensure a firm and stable fit. Loose-lay options that don’t require adhesives or locking mechanisms are another alternative.

Key advantages of vinyl plank flooring include its waterproof nature, making it suitable for moisture-prone areas. It also has the ability to withstand heavy foot traffic and daily wear and tear. Moreover, its relative ease of installation makes it a convenient option for both DIY enthusiasts and professionals.

Factors To Consider When Adding Vinyl Plank Flooring

Subfloor condition

The condition of the subfloor plays a crucial role in determining the necessity of underlayment for vinyl plank flooring. A smooth, level and dry subfloor may not require an underlayment, as the planks can be installed directly on top.

However, if the subfloor is uneven, has minor imperfections, or is susceptible to moisture, an underlayment can help create a stable and moisture-resistant base for vinyl planks. It can also help smooth out minor subfloor irregularities, ensuring a more comfortable and consistent installation.

Type of vinyl plank

Some vinyl plank flooring products come with pre-attached underlayment, which can eliminate the need for an additional layer. This integrated solution often includes a foam or cork backing that provides cushioning, sound insulation, and moisture protection.

However, if the vinyl planks do not have a pre-attached underlayment, an additional layer may be recommended to achieve optimal performance, comfort, and longevity.

Acoustic requirements

In multi-story buildings or homes with open floor plans, sound transmission can be a concern. Underlayment can play a crucial role in reducing the impact of noise and minimizing sound transfer between floors.

Adding an underlayment with sound-dampening properties, such as cork or foam, can create a quieter living environment. It helps prevent disturbances from footsteps or dropped objects.

Moisture considerations

When installing vinyl plank flooring over concrete subfloors, moisture can be a significant concern. Concrete is prone to moisture vapor transmission, which can potentially damage the flooring over time.

In such cases, a moisture barrier underlayment is highly recommended. These underlayments are designed to prevent moisture from seeping through the concrete. They ensure long-lasting protection for the vinyl planks and prevent potential issues like mold or mildew growth.

Choosing the Right Underlayment for Vinyl Plank Flooring

When choosing the right underlayment for vinyl plank flooring, it’s essential to consider the installation environment, flooring type, and specific needs. Areas with moisture concerns require moisture-resistant underlayments. High-traffic zones benefit from denser, compression-resistant options. 

The type of vinyl plank and any pre-attached underlayment may also dictate the additional underlayment needed. Soundproofing, thermal insulation, and moisture resistance are important factors to evaluate as well. 

The right underlayment can enhance acoustic comfort and regulate floor temperatures. It protects against water damage, ensuring optimal performance and longevity for your vinyl plank flooring.
