How it works

Underlayment is the layer of your flooring system between the subfloor and surface covering. The primary role of underlayment is to provide a flat, smooth surface for the floor covering. In addition, underlayments are critical for supporting your floor’s locking system while helping remedy imperfections in your subfloor, like minor degrees of leveling and small cracks.


Our high-performing underlayment for vinyl floors provides peace of mind against moisture, mold and mildew. FloorMuffler Encore offers additional acoustic performance and moisture protection to attached-pad flooring. As a result, they yield excellent value for homes and businesses, providing a cost-effective solution for protecting your flooring investment and extending its life span.

Installation methods

  • Floating

    An installation method that can be used with a variety of materials, including laminates, engineered hardwood, luxury vinyl and rigid core flooring. In this method, individual planks (or in some cases tiles) interlock edge-to-edge to form a single mat-like surface that simply rests on the underlayment.

How Does FloorMuffler® Encore Improve the Performance of Attached Pad Flooring?

There are numerous reasons to consider FloorMuffler® Encore for flooring with attached padding.

  •  It delivers outstanding acoustic performance. FloorMuffler® Encore provides additional sound reduction for attached pad floors. Attached pads often fail to meet the requirements for sound reduction that HOAs demand. FloorMuffler® Encore can help the flooring system achieve the required results.
  • It offers moisture protection. Moisture penetration from the subfloor can interfere with the finished flooring’s appearance and integrity. Our Encore underlayment for rigid core flooring provides superior moisture protection without the need for additional barriers.
  • It provides a comfortable and durable walking surface. Premium-grade underlayments are dense and resist compression. This allows the underlayment to provide a stable surface that protects the floor covering’s locking mechanism by limiting the amount of bending in the planks.
  • It can boost energy efficiency. Our high-performance underlayment offers additional insulation to keep your floors warm and help maintain more consistent indoor temperatures.
  • It can extend your floor’s life span. Minor subfloor imperfections, such as cracks and uneven surfaces, can shorten the life span of your floor covering. FloorMuffler® Encore reduces the effects of minor subfloor imperfections and helps your floor last longer.
  • It offers peace of mind. FloorMuffler® Encore is backed by our limited lifetime warranty. Manufactured in our ISO 9001:2015 certified facility, FloorMuffler® Encore is an industry leader in quality.
