Detailed Benefits of Having Underlayment on Plywood

We can’t exaggerate the importance of installing underlayment or laminate flooring on plywood. According to, underlayment plays a very important role for any residential and commercial flooring setting. In this case, you should select and install the correct underlayment and subfloors, hence you can ensure right wear and stability of flooring.

We figure out a couple of benefits of having underlayment on plywood. Let’s figure out those from the following. 

Underlayment is basically a thin material that needs to be installed between the floor and subfloor.

  1. First, after installing the underlayment on plywood, you will get a sound absorption facility. Because of the compression resistance, you will get a solid footing facility for the laminate flooring. Naturally, sounds will be created when you are walking around the floor. 

If the floor has underlayment, it will dampen and absorb sound transmission. With the sound absorption feature, the noise level will become lower. Here the sound will be transmitted via air-waves or impacts. This is the main amenity for those who want to keep the noise minimal or down. 

  1. Secondly, this material will add an insulation layer. With that insulation, the temperature that you want will stay in your room. On the other hand, if you don’t install underlayment, your plywood subfloor will release the air from the room.
  1. Another amenity is you can ensure a harmful moisture free floor. You will get a moisture vapor barrier in the underlayment which keeps your floor safe from mildew, mold and moisture. Moreover, the underlayment smooths out minor imperfections in the subfloor therefore; the floor becomes supported and stable. 

Note: If the crawl space is higher than your house’s main level, then you had better ensure sealing the crawl space of moisture properly. If you don’t do that, then the moisture alone will be blocked via underlayment.

  1. Finally, without installing underlayment, you can’t ensure flat flooring. So, installing the underlayment will help you hide the small minor imperfections, hence your room’s look will become perfect.

Different Types of Laminate Underlayment

Standard Foam Underlayment

Standard foam underlayment is thin and padded with foam. You will find it as the most common type today. Typically, the size it offers is ⅛ inch thick. Also, you have the option to choose your desired one from different roll sizes. 

Although you can’t use this type on any concrete sub floors, it will give you great service for timber sub floors. Plus, this underlayment is ideal to use on which demands minimal moisture. Because the standard foam underlayment doesn’t offer built-in moisture barrier.

Also, the price is a bit much lower, hopefully, it would be best for the low budget customer.

Combination Underlayment

The combination underlayment comes with almost the same feature as the standard foam underlayment. But, one major difference is here you will find moisture barrier attachment. After installing, the moisture can’t seep from underneath into the laminate. That’s why you can install this material on where the expected moisture level is higher such as the kitchen or basements. 

Cork/Sound Dampening Underlayment

Imagine, you don’t install underlayment on your plywood, what could happen then? The hard floor surface will create much sound. The inside hack is that the two hard surfaces will hit one another and create much sound. If that is your case, then use sound dampening underlayment. You don’t get only the sound reducing feature; rather this underlayment offers a moisture barrier.

Therefore, the material becomes very thin.

So, the question is which underlayment offers the best result in plywood subfloors? The best underlay option is the breathable foam-type underlayment, for plywood subfloors. Another option like vapor-barrier-type underlayment can’t provide you with a better result in plywood subfloor.
