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.

Foam Underlayment

  • Why foam underlayment?

Foam underlayment is a wonderfully affordable underlay product that provides some sound dampening qualities. This inexpensive solution can be used underneath any floor surface, but may not be idea in situations where you need to add a lot of height, as you are limited on options for thickness. Foam underlay provides excellent moisture protection, is mold and mildew resistant, and is easy to install, however, may not provide the ideal sound resistance compared to other underlay types.

Do I REALLY need underlay?

  • Yes, most definitely.

Underlayment is an amazing invention created by the flooring gods out of necessity. Underlay has an impressive list of benefits, including: adding warmth to your floors so your feet aren’t so cold on new tile flooring, adding comfort and a slight ‘give’ underneath wood or vinyl floors, reduced sound transmission (great for houses with noisy teenagers!), as well as reducing in room step noise. The image to the left is a very simplified example of using underlayment versus not using it, but as you can see the benefits greatly outweigh any reason not to.

Making your house a home

  • Products that work together

Foam underlays are incredibly versatile, since they do not contain any materials that could leak and stain a flooring surface. Foam is the perfect underlay option for virtually any floor, including underneath laminates, vinyl, engineered wood, cork, and bamboo. For tile flooring, a different type of underlayment is typically recommended.


  • What does it mean?

Foam underlayments are typically around 2mm or 3 mm thick. If adding height to your floor is important to your installation, we recommend choosing another product type such as rubber or cork, which come in substantially thicker options for your needs.

IIC / STC Ratings

  • What do they mean?

IIC stands for Impact Insulation Class, which refers to impact sounds such as shoes hitting the ground, dropping a cell phone, or other scenarios where something it dropped or impacts the floor. STC stands for Sound Transmission Class, which refers to any audible noise (not an impact) such as music playing aloud, a conversation, or a loud television, for example. With both of these ratings systems, the higher the number rating is for the underlayment, the better it will suppress sound, and the quieter a room will be. You may want to pay close attention to these ratings when shopping for underlayment if sound reduction is important to you.

Underlayment + Moisture Barrier + Improved Sound Reduction

  • The ultimate option in underlayment

3-in-1 underlayment product really are the best of the best. Not only do they save you time and money on not having to put down yet another product during installation, but they also have improved added sound reduction properties. This product may meet the quality level required by a professional, but it also works wonders in DIY-er or Weekend Warrior home installations as well.

We used this for a ceiling silencer between an aluminum ceiling panel and the beadboard we covered it with to help reduce rain noise. Works amazingly well.

  Not suitable for tile floors

I was not permitted to use this underlayment as it did not meet TCNA (Tile Council of North America) standards. It is suitable for laminate but not tile so be careful.
