Best Laminate Flooring Underlayments

Laminate flooring has been widely used by many homeowners in recent years because it looks and feels good under the feet, has almost the qualities of hardwood flooring, and comes at a cheaper price   

Many manufacturers in recent make the laminates attached to the underlayment however, some laminates don’t come with underlayment. You have to know the best underlayment to choose for your laminate flooring.

Qualities of a Good Underlayment:

I recently changed the floor in my dad’s old house and definitely I choose laminate flooring because I still wanted to maintain the classic look of our old house.

Before I had no idea there were different materials used for underlayment. Luckily, my supplier was good enough to explain them to me and gave me some ideas on what a good underlayment should be like.

According to many suppliers, a good underlayment should have the following qualities:

  • Act as a water barrier between the subfloor and your laminate flooring. It should protect your floor from moisture
  • Act as a good insulation material. Should protect your floor from being too cold during winters
  • be easy to install
  • Add a level of comfort to your laminate flooring.
  • Have good soundproofing qualities
  • Cost-effective

From the above, I narrowed it down to foam and cork. They are the most commonly used underlayment materials, so it was not hard for me to figure that out because they act as a moisture barrier and make sure your floor is not cold.

Foam and Cork are the best because these properties appear to them naturally unlike others that are manufactured to attain these properties

So why do you need an Underlayment for Laminate Flooring?

Unlike other floors, laminate flooring is a floating floor. Floating floors means that the floor is not nailed or glued down to the subfloor. To avoid friction between the laminate planks and the subfloor, you need a cushion for protection. In this case, an underlayment.

An underlayment has to be laid first to provide a good, smooth surface for the laminate to float.

Which Underlayment should I use for my Laminate Flooring?

The following factors will determine the underlayment you use for your laminate flooring-

  • The type of subfloor
  • The environment you’re in.
  • The purpose/the usage of the room.

1. The Type of Subfloor

Laminate flooring is greatly affected by water. For floors that are porous; for example, concrete, you will need to use an underlayment that is waterproof or rather an underlayment that acts as a water barrier.

This is because, concrete will allow water to seep up and without a water barrier, the moisture will weaken the joints on your laminate planks and damage your floor.

Also, when moisture sits for too long under your laminate flooring, you will start experiencing mold and mildew.

A good underlayment material that acts as a water barrier is polyethylene. It comes in sheets that you roll out and lay on your subfloor.

In case you are installing your laminate flooring on a plywood subfloor; you will need to use an underlayment material that is breathable.

Naturally wood is a material that needs to breathe. Using an underlayment with a water barrier may trap moisture under your subfloor which will only cause damage

2. The Environment you’re in

Living in cold areas, you do not want to step on a cold floor. In this case, you should choose an underlayment with a high R-value. The higher the R-value of your underlayment the warmer your floor feels in winter.

R-Value refers to the heat conductivity of your underlayment.

3. The purpose/The Usage of the Room

A commonly repeated mistake, mostly in areas that are of heavy traffic like the living room, is using a thick soft underlayment or a carpet in order to absorb the weight and feel comfortable while walking on it.

This will however flex your laminate and weaken the joints.

A good underlayment is Thin and does not allow movement of your laminate flooring.

Types of Laminate Flooring Underlayments

Underlayments will come in different types, they will differ in design, price, mode of application, etc.

Below are the three general classifications of underlayments.

  1. Standard Foam underlayment.
  2. Sound dampening underlayments.
  3. Combination Underlayment

1. Standard Foam Underlayment

This is the widely used form of underlayment.

It is made of thin foam padding which acts as a cushion between your subfloor and the laminate flooring. Usually, around 1/8 inches and comes in rolls of different sizes and lengths.

Standard Foam Underlayment is suitable in areas where you expect less or no moisture at all, as it does not act as a water barrier. However, if need be, you can combine it with polythene to make it waterproof.

2. Sound Dampening Underlayment

This type of underlayment is usually made from cork. Basically, it cancels out the noise produced when walking on laminate flooring.

It is ideal in places where noise cancellation is essential. This type of underlayment is not moisture resistant and if you want to use it in wet areas, you can lay polythene under it.

3. Combination Underlayment

This type of underlayment, as the name suggests, it combines standard foam underlayment with a moisture barrier. This type of underlayment prevents moisture damage to your laminate flooring through rising dampness.

It is slightly expensive compared to standard foam underlayment, but, the good thing is it can be laid almost anywhere. From bathrooms, basements to living rooms and can be used with many floors from plywood to concrete subfloors.
