  • Q:

    "Your responce on the difference between SP1, 2, 3 & 4 was great. Thanks. I get the STC designation now. What is the Impact Insulation Class (IIC) designation and what do those numbers mean?"

    • A:

      An Impact Insulation (IIC) rating is a measure of a reduction in impact sound transferring from a floor surface to the room underneath. The higher the number, the less the sound is transferred. (e.g. foot traffic, dropping items on the floor, etc.) This item has an IIC rating of 72 IIC which is a high rating.

  • Q:

    "What is the difference between the SP1, SP-2, SP 3 and SP-4 products sold by Less Care? The details appear to be the same for all of them, yet the prices are significantly different."

    • A:

      SP1 Is not rated SP2 has 60 Impact Insulation Class (IIC) and 53 Sound transmission class (STC) SP3 has 65 IIC and 58 STC SP4 has 72 IIC and 66 STC STC is airbornevibration and the rating is roughly how many decibles get through. Very loud shouting is roughly 85 decibles. The average wall is about 50STC so this woudl stack onto that and be blocking 116 with SP4.
