Installation of our Silver Silent underlayment is very easy and commonly done by our customers. Installation of this underlay is as follows.
  • Clean subfloor checking to make sure it is clear of any debris including nails by either sweeping or vacuuming.
  • From the corner of the room start to roll out the underlay with the aluminum on the bottom.
  • Radiant Heat: Install with aluminum foil on top for radiant heat and the recommended temperature is at or below 82° F.
  • It is recommended to lay the underlayment perpendicular to your floor installation.
  • Where moisture is evident, install vapor barrier tape to seam all seams that are not sealed by our self seal system.
  • Roll out a second roll of underlayment and butt the seams together with built-in self-seal tape and push down to adhere foam.
  • Tape the underlayment seams with a moisture resistant tape. Note: When installing underlayment in a basement or where a moisture barrier is required, we recommend extending the underlay 1-2" up the sides of all walls.
  • Continue installing the underlay repeating the previous steps until the floor is completed.

5/5 Silent Silver Underlayment
Cassandra Williams from Seattle, Washington
This product has been great for us. We used other underlayments in the past and they were good but not as great as the Silent Silver. This product really takes after its name. Silent Silver is highly recommended!!!!
