Iic Rating Flooring

Resilient flooring containing a foamed layer yields a higher better iic rating than one without it.

Iic rating flooring.

The international code council recommends that an acceptable level of performance for both stc and iic is 55 52 f iic. 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. Iic test the ability to block impact sound by measuring the resistance to transmission of impact noise or structure born noise. Iic is used to determine the amount of impact noise isolation.

The preferred level of performance for stc and iic is 60 57 f iic. Smoke mirrors and stc iic ratings stc is a sound rating that attempts to measure the effectiveness of an assembly in addressing ambient or airborne sound. Iic values and our floors. This is measured on a scale between 0 and 1.

More typical values fall between 35 and 55. A rating of 0 means that sound energy perfectly reflects off of a surface. The impact creates vibrations that travel through the flooring and produce sounds on the other side. An iic and stc rating will generally be 5 points higher than.

A midrange level is iic rating 60 which includes some vinyl flooring as well as wood and laminate floors. The test measures airborne sound transmission loss between 125 and 4000 hz iic. Impact insulation class iic sound rating. Sound transmission class stc.

The highest rating is iic rating 65 which includes cork flooring and carpet. The impact insulation class rating or iic measures how well a material blocks structure borne noise that s caused by one object impacting another. Examples include objects falling on floor kids jumping off couches tap dancing anything that stimulates footfall. As the stc rating iic tests measure sounds between 125 to 4 000 hz but in this case it measures the amount of vibrations that travel through the floor ceiling assembly.

That means that relatively small differences in stc ratings can mean big differences in sound blocking. It offers credible sound reduction for structure borne noise with exceptional iic ratings for all assemblies and does help increase the stc rating when used in a soundproof flooring assembly. Iic impact insulation class. The average wood floor has an stc in the neighborhood of 40.
