Peel and stick vinyl plank flooring requires an underlayment, which typically acts as a protective barrier between the flooring and the subfloor. However, given the variety of available options, selecting the best underlayment for peel and stick tiles in the market may be challenging. Luckily, we have done the work for you.

We have outlined the best underlayments for peel and stick tiles and discussed the important factors to consider while buying one that matches your needs.

What is a Good Underlayment for Peel and Stick Tile?

One of the most flexible flooring materials on the market is vinyl. A type of vinyl flooring is the peel and stick tiles which can be a quick and inexpensive design option because of the variety of styles available in this category.

The term "peel and stick tile," also known as "self-stick" or "self-adhesive vinyl tile," refers to vinyl planks or tiles that have an adhesive backing. Simply lay down planks or tiles like stickers and presto. The idea is the same if you've ever looked at peel-and-stick carpet tiles.

It is crucial to check with the manufacturer to determine whether an underlayment is required for peel and stick vinyl tiles. Some companies will state the kind of underlayment that can be used. Some even state that using the incorrect kind of underlayment may void the flooring's warranty.

With a 3-millimeter thickness and recycled felt construction, we found this underlayment to be perfect for insulating against sound. It will greatly minimize noise thanks to its STC rating of 66 and IIC rating of 71. Due to its Greenguard-Gold certification, the material is guaranteed to have few volatile organic compounds (VOCs).

This underlayment is suitable for laminate, engineered wood, and bamboo flooring, and we also noted that radiant in-floor heating systems could use it. This is because the underlayment allows heat to move evenly on vinyl plank floors, ensuring the floor is well protected from thermal shock.

What Do You Consider When Picking the Best Underlayment for Peel and Stick Tiles?

Although it's simple to believe that all peel and stick or underlayment perform similarly, a variety of things influence the performance and functionality. Below we have discussed some items that affect the underlayment for peel and stick tiles.

1. Subfloor Types

The type of underlayment you choose largely depends on your subfloor.

i. Concrete

Due to their extreme hardness, concrete subfloors require additional padding in the form of soft underlayments consisting of foam, felt, or cork.

Considering an underlayment that offers heat insulation and moisture control is recommended when installing the underlayment on concrete.

II. Wood

Felt underlayment works well with wood subfloors since they don't absorb sound and do a wonderful job of regulating temperatures and controlling moisture.

III. Existing Floors

Sometimes, a subfloor is made from an existing floor. Since they equal out any unevenness, rigid underlayments are the best option in this situation.

2. Types of Underlayment

Underlayments for peel and stick vinyl tiles come in various forms, each of which has particular benefits. Here are a few of them:

  • Foam- This is a popular option because it's affordable and efficient. Plywood subfloors go particularly well with foam. It's crucial to remember that foam isn't the best option for rooms with moisture problems.
  • Felt- This is an excellent option for sound insulation, but because it is mostly thin, it doesn't give much comfort. It is an environmentally beneficial alternative because it is manufactured from recycled fibers.
  • Cork- Cork is a good option for areas that experience mold and mildew and offers excellent sound insulation. For households with people with allergies, it's a brilliant option.
  • Particleboard- Although particleboard is a less expensive option, it lacks strength and cannot withstand moisture exposure.
  • Plywood- Similar to particleboard, plywood is a superior choice since it is less susceptible to damage from moisture.
  • Rubber- This offers excellent sound and heat insulation and protects against moisture.
  • Oriented Strand Board(OSB)- Even though it is made similarly to plywood, Oriented Strand Board (OSB) is more resilient.

3. Thickness

Underlayments for vinyl flooring typically range in thickness from 2 to 3 millimeters, but they can also be as thin as 1 millimeter or as thick as 6 millimeters.

It would be easy to assume that a thicker underlayment would signify a higher degree of performance. However, advancements in manufacturing have allowed thin underlayments to provide excellent comfort and insulation too.

Laying Laminate Flooring. Green foam underlayment.

Underlayment thickness is largely considered when installing various types of flooring throughout a house. When determining the underlayment's thickness, it's crucial to ensure that the vinyl tile flooring is the same thickness as the vinyl tiles.

4. Sound Insulation

Sound insulation is one of the crucial advantages of vinyl flooring underlayment. Impact Insulation Class (IIC) or Sound Transmission Class (STC) ratings, as well as negative decibels (-dB), are two ways to indicate how much sound insulation an underlayment offers.

5. Thermal Insulation

By adding an extra layer of thermal insulation, underlayment helps to prevent cold floors in the winter. As a result, the cost of heating is reduced, saving money over time.

Finishing materials for flooring. Laying parquet boards on natural cork for underlayment.

Some underlayment types will be given an R-value rating depending on the thermal insulation they offer. A greater R-value indicates better insulation. An R-value between 0.2 and 0.4 is considered ideal.

6. Moisture Protection

Despite some peel and stick tiles having a waterproof design, they can warp when exposed to moisture from the subfloor. In moist places like basements, a vapor or moisture barrier may be required in addition to a regular underlayment.

In order to stop the growth of mold spores in moist or humid environments, some underlayments are made with antimicrobial qualities.

Tips for Installing Underlayment for Peel and Stick Tiles

After selecting the ideal underlayment for your peel and stick vinyl floors, it's time to think about installation.

It's important to carefully follow the manufacturer's instructions that come with the majority of products in order to ensure that the installation is done correctly. Here are some tips you should consider regarding self-adhesive vinyl tiles installation;

  • Clean the subfloor and ensure there are no dusty floors
  • Cut out the underlayment to ensure it fits as you lay it out from wall to wall.
  • Connect the individual components together by using adhesive.
  • Make sure gaps do not separate the components.
  • Always follow the manufacturer instructions

Frequently Asked Questions (FAQs) on Underlayment for Peel and Stick Tiles

1. Does peel and stick tile need underlayment?

Yes, it is crucial to have an underlayment for self-adhesive tiles. However, the underlayment must be completely flat and clean to apply peel-and-stick vinyl tile successfully. An uneven, damp, or dusty flooring may prevent good adhesion. If the underlayment is not stable and clean, peel-and-stick flooring tiles become loose over time.

2. Can you get peel and stick tile wet?

Peel and stick tiles are moisture- and water-resistant in humid areas since they are made of multi-layer vinyl. However, water can seep through the cracks and harm the flooring or wall if water is left on them. Avoid this by applying a sealer to the tiles or simply mopping up any spills.
