Iic Rating Of Carpet

A midrange level is iic rating 60 which includes some vinyl flooring as well as wood and laminate floors.

Iic rating of carpet.

The impact insulation class iic rating is a measurement of sound transmission from the floor to a room beneath it. An iic and stc rating will generally be 5 points higher than. The higher the rating the less sound gets through. The preferred level of performance for stc and iic is 60 57 f iic.

The transmission of these sounds through floor ceiling assemblies such as those found in multi level homes and apartments will be inhibited by underlayments with higher iic and stc ratings. But when you compare products look beyond the number. It all begins with how sound is generated and the medium it transfers through. The iic rating measures impact sounds such as footfalls dropped objects etc.

An iic rating 50 means that the flooring material has minimal sound absorption capabilities. I hope this information was helpful for you. Iic 65 is a high level of impact sound transmission absorption and includes superior sound reduction materials like carpet and cork. A f iic and f stc rating.

Surfaces and areas under the floor influence impact isolation class. The subfloor ceiling assembly and presence of an underlayment during testing impact the rating from one manufacturer to. Iic values can range from as low as 25 for lightweight residential construction with no floor covering to over 65 for commercial construction with carpet. When evaluating flooring underlayment sound deadening and acoustical ratings are one of the things homeowners or hoa considers.

More typical values fall between 35 and 55. The iic rating of a condo unit floor above another condo unit should be 75 or more to match what is provided by carpet and reasonably thick carpet padding. For multi family structures some codes require an iic of 50 or more when tested in the laboratory or 45 or more when tested in the field. Some condos prohibit hardwood flooring entirely to make sure noise transmission into lower units is not increased.

The f iic and f stc is conducted in the field where sound is not as controllable hence the 5 point difference. The highest rating is iic rating 65 which includes cork flooring and carpet. The main test done by flooring industry is the impact insulation class iic ad sound transmission class stc. The iic and stc is conducted at a controlled laboratory.

The iic rating is the determined by using a standard tapping machine with five steel faced hammers to strike a test floor material generating sounds between 125 hz 4000 hz.
