What Do I Put Under Vinyl Flooring?

Installing vinyl flooring can be a great way to update your home's look, but it's important to start with a solid foundation. The right underlayment can make all the difference in the performance and longevity of your new floor.

Purpose of Underlayment

Underlayment serves several important purposes for vinyl flooring, including:

Moisture and vapor barrier: Prevents moisture from seeping up through the subfloor and damaging the vinyl flooring
Sound reduction: Absorbs noise and reduces impact sound
Thermal insulation: Helps keep the floor warmer underfoot
Leveling: Smooths out any unevenness in the subfloor

Types of Underlayment

There are several different types of underlayment available, each with its own advantages and disadvantages:

Cork: Provides excellent sound and thermal insulation, but is more expensive
Foam: The most common type of underlayment, available in a range of thicknesses and densities. Provides good sound reduction and is relatively inexpensive
Rubber: Very durable and water-resistant, but more expensive than other options
Composite: A combination of materials, such as cork and rubber, offering a balance of performance and cost

Choosing the Right Underlayment

The best underlayment for your vinyl flooring will depend on several factors, including:

Type of vinyl flooring: Some types of vinyl flooring, such as luxury vinyl tile (LVT), require a specific type of underlayment
Subfloor condition: If the subfloor is uneven or has moisture issues, you may need a thicker or more durable underlayment
Desired performance: If you want maximum sound reduction or thermal insulation, you will need to choose an underlayment with higher ratings in those areas

Installation

Once you have chosen the right underlayment, it's important to install it properly to ensure optimal performance. Here are the steps involved:

Prepare the subfloor by cleaning and removing any debris
Roll out the underlayment over the subfloor and cut it to fit the room
Tape the seams of the underlayment together using a moisture-resistant tape
Install the vinyl flooring over the underlayment according to the manufacturer's instructions

Conclusion

Installing the right underlayment for your vinyl flooring is essential for maximizing its performance and longevity. By following these tips, you can choose the best underlayment for your needs and ensure a successful installation.
