Why do I need underlayment for laminate flooring installation?

Underlayment for laminate flooring is a must. Since laminate is a floating floor, it must be evenly distributed across your subfloor. Underlayment is what allows the floor to float, gives it stability, support, noise reduction, and supports the locking systems in between planks to assure the sturdiest flooring project. There are a number of different underlayment options and selecting the right one for your project can get somewhat complicated.

How to Choose Your Underlayment

The best way to determine which underlayment you need is by looking at your subfloor. The two most common subfloors are wood and cement and there are special differences you must pay attention to when looking for the proper underlayment.

Wood Subfloor

If you are installing laminate flooring on a wood subfloor, you should use standard to premium underlayment. If you wood subfloor is pretty sturdy, you won’t need any special underlayment. If your subfloor is a little uneven or creaky, you may want to get a premium underlayment that has noise reduction and cushion capabilities. Here are a few options:

Cement Subfloor

If you are installing laminate flooring on a cement subfloor, you should use a vapor underlayment. Vapor underlayments protect your flooring from any moisture that could seep up from the cement subfloor. You should also use one of these underlayments if you are installing in a below-ground level installation to help with moisture control. Here are a few options:

Some Exceptions

Pre Attached Underlayment

Pay close attention to the back of your laminate flooring. If you have purchased a laminate flooring that has underlayment already attached, then you should not use extra underlayment. Having too much cushion can destroy the integrity of the locking system and cause the floor to become unstable. There are some exceptions to pay attention to, however.

Wood Subfloor

If you are installing laminate flooring with pre-attached underlayment on a wood subfloor, you do not need any additional underlayment. The attached underlayment will allow your flooring to float just as standard underlayment would. Be sure to prepare your subfloor before installation to assure a seamless and smooth surface.

Cement Subfloor

If you are installing laminate flooring with pre-attached underlayment on a cement subfloor, you need to install a vapor barrier to prevent moisture from seeping up through the subfloor. Do not install a vapor barrier that has extra cushioning. Here are your options:

  1. I want to install laminate floors. I didn’t realize that they need to have underlayment! I think I’m going to rely on a professional to handle this stuff for me. I feel like I’ll make a mistake and mess it all up.
