With what type of floor covering can I use QuietDown?

Laminate, engineered wood, solid hardwood, and ceramic tile.

Does the smell of rubber go away?

Yes it does. QuietDown is manufactured using recycled rubber, which have an odour of rubber. Left in the open the smell will dissipate after a few days. Once covered by the floor covering the smell will no longer be detectable.

Can I use QuietDown in my basement?

QuietDown Max is 100% vapour proof and we have had a number of customers install it in their basements. QuietDown Max will prevent moisture from traveling upwards into your floor covering, but if you have a wet basement issue, QuietDown will not solve your problem. It is recommended that you fix the root cause of the moisture, then install your floor coverings.

What type of sound does QuietDown reduce?

Mid to high frequency impact sounds such as people walking in hard soled shoes, children dropping toys, pots, pans or items being dropped in kitchens.

I want to get rid of the sound of booming bass, will QuietDown work for this?

No. Most acoustic underlay products will not get rid of low frequency sound transmission. In order to reduce low frequency sounds you need a combination of mass and structure, similar to the egg carton products you see in sound studios. This type of shape does not lend itself to underlay.

Why does QuietDown come in sheets and not rolls?

Homeowners and contractors have told us that rolls are heavy and cumbersome on a job site. Sheets are preferred for ease of installation.

What is IIC?

IIC stands for Impact Insulation Class. It is a unit of measure used in acoustics to measure the amount of impact sound transmission that passes through a subfloor.

Does the higher IIC number mean the product is better?

Not necessarily. Unfortunately, a number of manufacturers claim that their products achieve extremely high IIC numbers. The true measure of importance is the difference between the IIC value of the floor prior to the installation of the acoustic product and the IIC value of the floor after the acoustic product is installed. Extensive laboratory and field tests of QuietDown have been conducted by independent organizations; results of these evaluations can be downloaded here.

Can QuietDown be used on walls?

QuietDown is tested and approved for use as an underlay below hard surface flooring. We do not recommend its use for any other application.
