The Best Underlayment for Vinyl Plank Flooring | Top 8 Picks

Best Underlayment for Vinyl Plank Flooring

There are a gazillion different choices you have to make when building a home of your own. When it comes to flooring, vinyl can be a great affordable option. But choosing the right flooring will not give you the best results by itself; you have to take note of the underlayment too.

I created this article to help you find the best underlayment for vinyl plank flooring. The right underlayment will not only create a great base for your flooring to go on, but it will also provide certain benefits. I will discuss these specific features in the reviews and provide some additional information.

Without further ado, let’s begin!

Best Type of Underlayment for Vinyl Plank Flooring

The material of vinyl plank flooring is quite resilient, so you really do not require much help from the underlayment. It is affordable, moisture-resistant, and also scratch-resistant.

When it comes to the underlayment, the types of vinyl plank floorings vary, and so do their underlayment requirement. Here is the best type of underlayment for each different type –

Felt, Foam, Or Cork Underlayment for SPC Vinyl Plank

The core of SPCs (Stone-Plastic Composite), as you may guess from the name, have stone powder mixed in. This provides durability but at the cost of thickness. As the stone powder has to be mixed in, these planks cannot be made too thick. Moreover, they do not feel very comfortable on their feet due to their robustness.

For SPC, you should get felt, foam, or cork underlayment. Softer underlayment pairs are better with this type of flooring.

Thin Underlayment for WPC Vinyl Plank

WPC Vinyl Plank (Wood-Plastic Composite) is similar to SPC, but instead of stone powder, ultra fine powdered wood is mixed inside the core. As a result, they are not as hardy as SPC flooring, but the softness is not a bad thing. It is more comfortable to walk on.

This type of flooring is comfortable, with a natural feel that has more bounce. They also tend to be thick. Because of that, thin underlayment pairs best with WPC. Try to find 1 mm underlayment for WPC planks.

Plywood Underlayment for Pure Vinyl Plank

You can also find vinyl planks that do not have any mix-ins in their core. The core is made of vinyl foam, which is neither as robust as SPC cores nor as comfortable as WPC cores.

For this type of vinyl plank, you need more specific underlayment meant to be used with pure vinyl planks. Consider getting plywood underlayment for added durability.

How Thick Should Underlayment Be for Vinyl Flooring

For vinyl flooring, you do not require as thick of underlayment as you would for other types of flooring. Usually, underlayment for vinyl sheet flooring has a thickness in the range of 1 to 1.5 millimeters. It is the same for other types of vinyl flooring, too.

Buying Guide

In this section, we will highlight a few aspects that should be kept in mind when you are shopping for underlayment for vinyl plank flooring. These factors will help you choose best rated underlayment for vinyl plank flooring.

Subfloor Compatibility

Depending on the type of subfloor you have, your requirements for underlayment will change. For example, concrete lets in moisture easily, so it needs underlayment that can absorb the moisture. Wood subfloor also requires underlayment that can prevent vapor build-up, as it may cause the wood to warp.

The location of the subfloor matters, too. If you are not on the ground floor, get something that will cancel out noise so as not to disturb your downstairs neighbors. For the ground floor, vapor protection is a must from the underlayment.

Flooring Compatibility

We have already discussed the type of underlayment you should get for different types of vinyl plank flooring. As vinyl planks utilize a click and lock setting, the underlayment should provide enough support to the joints. Also, thick underlayment is generally not a good option for glue down vinyl planks.

Material

Different materials have different benefits and shortcomings. You should consider what you want from the underlayment and choose the material that meets that standard the best. The common underlayment materials are –

  • Foam

These are the industry standards and the most affordable kind of underlayment. They are soft, making the floor more comfortable to walk on. However, they do not provide any protection from excess vapor, so stay clear of them is moisture is an issue.

  • Cork

Corks are great at concealing minor irregularities on the subfloor. They are also good for protection against mold. However, cork is not recommended for vinyl plank flooring. Also, they struggle if there is a lot of moisture.

  • 2-in-1

This underlayment consists of two layers – one provides padding, making it more comfortable. The other is a vapor barrier for protection against humidity. This is basically the best of both worlds.

  • 3-in-1

As you can guess, this one consists of three layers – one for cushioning, one for vapor protection, and one for sound concealing. This is perfect if you need help with both noise and moisture.

  • Felt

Felt is a great insulator, and therefore, will keep your rooms warm during colder days. They also absorb sound well. However, as they are denser than foam, you will not get the same level of comfort.

  • Plywood

This is the best material for combatting moisture. However, it is not the most rigid, so you will not get much support. Beware of this if you have heavy furniture.

Frequently Asked Questions

Why should I get vinyl underlayment?

An underlayment, while not always needed, can smooth out minor imperfections, make the floor more comfortable, add thermal insulation, absorb noise, and dissipate trapped moisture. This is why you should consider getting them unless the manufacturer of the flooring suggests not getting any.

Which underlayment material is best for absorbing sound?

Felt and cork are great materials that conceal noise well. Among them, felt is thermally insulating but does not feel very comfortable. On the other hand, cork is good at dealing with mold and mildew, but it does not fare the best with excess moisture.

How do luxury vinyl planks (LVP) and luxury vinyl tiles (LVT) vary?

LVP comes in a plank shape and mimics the look of real wooden planks. LVT comes in a tile shape and mimics the look of a stone floor. So, the difference lies in size and looks.

What do STC, IIC, and R-value indicate?

STC value indicates how good underlayment is at absorbing ambient noise, such as TV, talking, etc. IIC indicates how good it is at absorbing sounds caused by impact, such as walking, stomping, jumping, etc. R-value indicates heat insulation.

Conclusion

As you have seen, picking out the best underlayment for vinyl plank flooring is not a piece of cake. It takes a lot of consideration, careful planning, and research. We hope this article has been able to aid you in the process, as that was our goal when we started researching for it.
