Can I use a thick or double layer underlayment with laminate flooring?

No, it is not recommended to install a thick or double layer of underlayment with laminate flooring.

Underlayment is manufactured and meant to be used as only a single layer to allow your floor to be balanced and float properly. If you install any additional underlayment, the base for your flooring will end up being too soft and could jeopardize the integrity of the locking system.

Your Options

What you can do is install a premium underlayment that gives you exactly what you need. The reason why we get asked this questions is because people are worried about having proper sound reduction or enough cushion for accidental falls.

If these sound like your concerns, here are some options:

    I am getting ready to renovate a home I just brought. My question is I have tile in the livingroom but not in the hallway or my bedroom. The floor is uneven where the tile end. I want to do laminate flooring throughout the home is there a way to continue from room to room without breaking up the tile. I have set a strict budget

      Hi Sonya, thanks for your question. If you don’t want to do a transition molding from one height to another, you could add a plywood subfloor overtop of the tile. You will need to make sure it is sturdy, level and within the requirements of the manufacturer.

    I own a 2nd floor condo in Florida and the Condo by -laws won’t allow anything but carpet on the upper floors due to noise transmission. We use this as a rental unit part of the year to defray costs. I am trying to convince the board members to allow condo owners to have multiple options for flooring options other then carpets on the upper floors.

    I would like to know what is the best sound pad underlayment available to use with either luxury vinyl plank or floor laminate to achieve superior sound proofing equal or better then carpet.

    My goal is to provide recommendations to the condo owners with more floor options and a longer lasting product then carpet.

    Our condos have 6″ concrete flooring with no acoustical ceilings in the apartment below.

    I have a house built in 1930 ,with floors that need to be leveled due to wall removal. I don’t need a premium floor that will last a very long time but one that is nice looking and somewhat durable and seals out any imperfections in the sub floor. The house has a small crawl space under it with diagonal wood then sub floor. Which underlayment do you think I should use. The house is in North Carolina and can get some high humidity days
