Hardwood Flooring: When and Why Underlayments are Required?



Date Posted : August 15, 2016


Underlayment is required for any installation of laminate flooring or engineered real wood flooring. Both types of flooring are installed by a "floated" or "free-floating," method, meaning they are not actually attached to the sub-floor. The individual boards are only secured to each other by gluing the mating tongue and groove edges or by simply clicking together the special joints of the "no-glue" type. The underlayment is placed over the sub-floor first then the flooring is assembled on top of the underlayment.

The underlayment is placed over the sub-floor first then the flooring is assembled on top of the underlayment.

The function of underlayment is to absorb some of the minor (very minor) imperfections in the sub-floor; to help deaden sound when walking on the floor (since it is not attached to the sub-floor); and to slightly (very, very slightly) soften the feel when walking on the floor. It is very important to understand that underlayment for laminate and floating wood floors is not the same as padding for carpet. Unlike padding for carpet, a thicker underlayment will not make laminate or wood flooring feel softer. It will, however, reduce overhead sound in rooms below the flooring in addition to lessening the affects of sub-floor imperfections.

Solid cork underlayment can be used under most all floating laminate or wood floors. However, as with some foam underlayments, you may need to install a moisture barrier under the cork, if applicable. Most manufacturers accept 6mil think plastic sheeting as a moisture barrier, but to be sure check with your specific flooring manufacturer or with one of our flooring consultants.

Another benefit of cork underlayment is that it can be used with most all wood flooring installations, including glued down, nailed down and stapled down. It can also be used under ceramic tile, cork flooring, and bamboo flooring. One important note: whenever you are installing flooring by a method other than free-floating, the cork underlayment must be glued to the sub-flooring as opposed to simply laying it down.

Note: If you live on the second floor, or higher, of a condo building, there may be rules that dictate the type of underlayment required. The requirement may call for one that reduces sound even more than the modified or upgraded types. In such cases, cork is often the specified underlayment. However, if cork is not specified, then we highly recommend "The Silencer" as a less expensive alternative that will provide excellent sound reduction. If you do live in a condo, we strongly suggest getting a copy of the rules and verifying their requirements before buying any material. We also suggest that you get a letter signed by the condo board, prior to starting any flooring work, stating that your choice of underlayment is acceptable.
