Your iic rating or impact insulation class is a major factor in how much sound tenants will hear directly below a floor ceiling assembly.
Iic rating carpet amp.
The iic number is roughly the reduction in decibels that a partition creates in the 100 hz to 3 150 hz range when tapped by the testing machine.
Iic 60 indicates a medium impact sound absorption quality and encompasses floorings such as wood laminates and some vinyls.
I am doing reno s on a condo and they have a specific requirement.
The rating is determined by using a tapping machine on an existing assembly and measuring the amount of sound that comes through below.
An iic rating 50 means that the flooring material has minimal sound absorption capabilities.
The results of the test are rated in terms of the impact insulation class iic.
The international building code suggests a rating of 50 or more for iic and stc but allows 45 or more for fiic or fiic field tests.
Iic 60 considered a medium level of impact sound transmission reduction.
Iic 65 is a high level of impact sound transmission absorption and includes superior sound reduction materials like carpet and cork.
The highest rating is iic rating 65 which includes cork flooring and carpet.
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.
Without the addition of sound isolation products the iic rating of basic wood structures will rate better than concrete structures because they are naturally more resilient.
The easiest way to achieve the required iic rating of 50 is to use carpet and underlayment as your flooring which can give you 20 points.
The iic ratings for basic wood structure with no resilient underlayment is around 40 to 45 iic.
The iic ratings for basic concrete sub floor with no resilient underlayment is around 28 to 35 iic.
Surfaces and areas under the floor influence impact isolation class.
Luxury vinyl flooring and iic stc ratings.
Iic 50 the least amount of impact sound transmission reduction considered effective.
How do i find out the impact insulation class rating and sound transmission class ratings for the lifeproof luxury vinyl flooring.
Iic impact insulation class fiic field impact insulation class stc sound transmission class and fstc field sound transmission class sound testing procedures are all included in the international building code as official test methods for sound evaluation.
There are also a number of underlayment options for harder surfaces.
More typical values fall between 35 and 55.
Iic 65 considered a high level of impact sound transmission reduction that would satisfy most occupants.
