How To Insulate Laminate Flooring – Best Underlayment Options

When installing laminate flooring, underlayment is an important step everyone should consider. In fact, most laminate floors require an underlayment nowadays. An underlay greatly enhances the performance and feel of the floor and also acts as insulation. 

You must use underlayment to insulate laminate flooring. You’ll need to consider different underlayment options as they all have different qualities. You should ideally look for a thick underlay with a high tog rating to ensure maximum comfort.

Can You Insulate Laminate Flooring?

Yes, it is recommended to insulate laminate flooring as there are several advantages of doing so. Proper insulation can help keep your floor warm during the winter season. Similarly, the insulating layer can help keep the floor cooler during the warm season.

This may even help lower your electricity bill as it reduces the need to run electric appliances. 

Not only does insulation regulate the room temperature, but it also protects your floors from moisture, mold, mildew, and other damage. 

Are Laminate Floors Cold In Winter?

This will depend on what the laminate flooring is laid on. If it is at ground level, straight onto a concrete / stone floor, it will be quite cold therefore insulation is highly recommended. If it is being laid onto wood or on an upper level of a property, it won’t be too cold in the winter.

In general though, laminate floors are a great choice for flooring in all climates including cool ones. It looks a lot like natural wood and has insulation properties similar to vinyl planks. It is usually comfortable to walk on without your feet getting too cold. 

That being said, laminate flooring is still much colder than a carpet. So, you might want to consider adding insulation for getting that extra warmth on cold winter mornings.

You might be surprised to know that ceiling fans can also really help in the winter.

How do I keep my laminate floor warm other than insulation?

If you have a laminate floor, there are a number of options you can consider to make it warmer and more comfortable during the winter.

1. Rugs

Wooden Floor With Rug

The simplest and most straightforward solution that always works is adding a rug on top of your laminate floor. Rugs can act as a form of insulation and prevent heat loss from the floor. Plus, they are extremely cost-effective as they’re inexpensive and can minimize the need for turning on heaters.

For bedrooms, bathrooms, and the kitchen, sheepskin rugs are usually quite effective. You can also look for runner rugs to place in the hallway or floor landings. Not only do rugs add a cozy feeling, but they can also improve the aesthetic of your home. 

2. Under-Floor Heating

Another option for keeping your laminate flooring warm is under-floor heating. Just like a regular heating system, you can adjust the temperature and set a timer according to your needs. Electric and water underfloor heating are both compatible with laminate flooring. However, this solution will be quite expensive.

Not only does the installation cost a lot, but the heating system will give you a higher electricity bill too. So, you might want to consider the pros and cons of this solution, especially from a financial perspective. 

3. Heaters

Placing a small heater in the room can easily help you keep the temperature warm with laminate flooring. Electric wall heaters are very easy to install and they do a good job at radiating warmth to the surroundings. 

Insulation for laminate flooring

Insulation under your laminate flooring can make your home much more comfortable. In fact, it’s advised to have some form of underlayment if you’re considering laminate floors.

It is a necessary step while installing laminate flooring as it acts as a cushion between the subfloor and the laminate. This makes the floor more resistant to extreme weather changes and works as a vapor barrier to prevent the floor from absorbing moisture.

Which floors should be insulated?

If you want, you can get all the floors in the house insulated. However, it is usually the most beneficial to insulate the ground floors. It isn’t always necessary to get the upper floors insulated.

Floors located above any unheated rooms should also be insulated.

Thermal Ratings For Insulation

If you’re looking for an underlayment that can also insulate your home, you need to look at thermal ratings. This rating measures the ability of the underlay to actually insulate your home.

Not all underlayments are the same, nor are they equally effective. So, thermal ratings can work as a guide for those who prioritize insulation.

An R-value is the standard measurement assigned to different types of underlayment. The higher the R-value, the more insulating effectiveness you will get from the underlayment.  A low R-value means less insulation, whereas a high R-value means there will be less heat loss from the underlay. 

People living in colder climates should look for high R-value underlays for additional heating under the floor. This also helps if you already have a floor heating system in place. Similarly, a high R-value can also keep warm air away in the hotter months. 

Most underlayments come with an R-value of 2 or 3. Of course, as the R-value goes up, so does the price point of the underlay. 

What is the warmest underlay for laminate flooring?

One of the most important factors while searching for the warmest underlay is the tog rating. A higher tog rating means that the underlay will be more effective at keeping the floor and room warm. 

In terms of material, felt is usually considered best for insulating a laminate floor. Another option is cork which has a high quality and provides a lot of comfort with similar insulating properties. 

Here are some of the top underlay recommendations for insulating a laminate floor. 

FloorLot Super Gold Laminate Underlay

FloorLot Super Gold is famous for being one of the best insulating underlays especially made for laminate floor. With a high thickness of 5mm, and a high tog rating of 0.9, you can count on it to add warmth and comfort to your living space.

Does Underlay Really Work As Heat Or Floor Insulation?

Absolutely. An insulating underlay made from high-quality material can act as a thermal barrier and help regulate room temperature significantly.

While choosing your underlay, just remember to consider all the important factors including:


When choosing your underlay, you need to take the location of the floors in account. If the laminated floor is upstairs, you should look for an underlay with noise reduction abilities. In the case of kitchens and basements, an underlay that controls moisture would be more useful. 


The thickness of the underlay needs to be just right for insulation to be truly effective. If the underlay is too thin, your floor will continue to feel hard, loud, and not provide much comfort. On the other hand, if the underlay is too thick, it may begin to warp and push the floor away.

You should also remember that the required thickness varies according to the material. If you choose a cork underlay, you will need double the thickness as compared to a felt underlay. For felt underlays, 2-3mm thickness is usually adequate. 

Tog Rating

You must have heard the term “tog rating” a lot but what does it really mean? Tog actually stands for ‘Thermal Overall Grade’ so it measures the thermal insulation of the product. 

Tog ratings are usually given to quilts, duvets and sleeping bags, but they are also given to underlays. With a higher tog rating underlay, you will get higher insulation. Remember, underlay tog ratings also vary, depending to the material of the floor you use.  


Hopefully that has helped explain everything about insulating laminate flooring. It’s a highly recommended step to take before laying your floor to keep heat in your home and to keep your feet nice and warm!
