IIC - Impact Insulation Class - The higher the number, the better the sound insulation.The IIC is a measure of how much impact sound (walking,
kids playing, etc.) is reduced after traveling through the floor covering, underlayment, and building structure and emerging in the room below.
------
STC - Sound Transmission Class - The higher the number, the better the sound is absorbed.The STC is a measure of how much airborne sound
(speech, TV, stereo, etc.) is reduced after traveling through the floor covering, underlayment, and building structure and emerging in the room below.
------
Delta IIC - The higher the number, the better the sound won’t transfer from another room.The Delta IIC rating is the best rating to consider when
comparing the performance of different types of underlayment.

R-Value - The higher the number, the better and the warmer the floor will feel under foot.
R-Value is a measure of the insulating ability of the underlayment.
------
Moisture Emissions Protection - The higher the number, the better the protection.
Result expresses the amount of moisture emissions the concrete emits using a calcium chloride test.
------
Water Vapor Transmission Rate - The measure of the passage of water vapor through a material during a
period of time. The lower the number expresses the less permeable the material is. ASTEM E96.
