All About Underlay
An underlayment’s main job is to insulate against sound. To ensure they can do their job, most underlays undergo a series of tests. We don’t need to go into specifics of these tests, just like we don’t need to know the specifics of the alien tests they do in Area 51. There are two numbers that come from these tests that you will want to pay attention to: the STC and IIC ratings. STC stands for Sound Transmission Class and IIC stands for Impact Insulation Class. STC evaluates the ability for the underlay to reduce room noise. This would be noise from talking, TVs, radios and the like. And who wants to hear their neighbor playing Europe’s “The Final Countdown” on loop? IIC evaluates the ability for an underlay to block impact sound, which would be footsteps, children dropping toys or adults pretending to be the Ultimate Warrior and dropping suplexes all night. So what do these mean to me, you ask? Well what you need to take from these is that the BIGGER the number of either test, the better the underlay is at insulating against sound. Bigger is better in the underlay world.

Types of Underlayments
- Rubber Underlayment Rubber underlayment is one of the best underlays for most flooring types. This underlay features some of the best sound resistance and one is of the most versatile underlays we offer. This underlay can be installed in areas where water may be an issue and is great over wood and concrete subfloors. When installing rubber underlay, it is recommended that it be loose laid, but you can install it with double sided tape, glue, nails, or staples. Rubber underlay is mold and mildew resistant and helps keep the cold air from down in the subfloor from coming up to your feet.
- Cork Underlayment Cork underlay is the most popular underlayment used in condos, apartments and other high rise buildings. This is because cork is great at inhibiting sound from floor to floor and it can be installed under any flooring type. Cork underlayment is typically adhered to the subfloor, but can be installed with double sided tape or floated. We do not recommend putting nails or staples through the underlay since that will diminish the cork’s acoustical value. Cork is naturally resistant to mold, mildew, and water. However, on ground floors or in basements, it is recommended that the cork be installed with a vapor barrier underneath. This is due to moisture being able to flow through the cork underlay which can damage your beautiful new flooring. Cork underlay also has great thermal properties, keeping the cold air from coming up from your subfloor.
- Rubber Cork Underlayment Rubber Cork underlay is composed of cork and rubber. Just like Paul McCartney and Stevie Wonder, these two materials make great music...I mean, a great underlay...together. Rubber cork underlayment is great for crack suppression. Have you ever installed a tile floor on the first level or in a basement and then, after a year, you start noticing cracks appearing in your floor? This is due to your foundation settling. Homes are meant to move, but this movement can spell trouble for your floor. This is where rubber cork underlay comes to the rescue. It will help to prevent the subfloor cracks from affecting your floor. Rubber cork underlayment can be installed under most flooring types, but it’s great under hardwood and tile floors. These rolls are mold and mildew resistant and feature the same thermal properties that cork has. Rubber Cork rolls are typically installed loose laid, but can be installed with double sided tape or adhesive.
- Foam Underlayment Foam underlay is the most popular underlayment for flooring. This is due to the fact that foam is the cheapest underlay option, but still provides excellent sound reduction properties. Foam is very easy to install and is popular under carpet and floating floors. Many foam underlays have an attached vapor barrier which helps protect both the floor and underlay. Some foam underlays come with attached adhesive strips which makes installation a breeze, while others have to be glued, nailed, stapled or taped. Foam is mold and mildew resistant and has thermal properties.
