Sound Transmission Class (STC). Impact Insulation Class (IIC). And even Delta versions of these ratings. This oftentimes competing and confusing information has the capacity to overwhelm when assessing the best sound control product for a flooring installation. Which ratings should contractors go by? How are they measured? What do they really mean?
We asked manufacturers in the segment to weigh in. They responded at such a high volume that we’ve decided to split this story into two parts over the next two issues. We hope this deep-dive into sound control helps clear up some confusion about how these products are tested and how they are designed to perform.
