| Many owner occupants of condominiums and other
multi-family dwelling share a preference for hard surface floors such as ceramic tile,
quarry tile, marble, hardwood flooring, wood parquet or vinyl tile. Foyers, kitchens,
bathrooms, work areas and special purpose spaces are typical candidates for non-carpeted
floors. Some localities have adopted building codes which
require minimum IIC (Impact Insulation Class) and STC (Sound Transmission Class) ratings
for floor/ceiling systems. California has established 50 as their minimum acceptable IIC
and STC rating for residential construction.
An IIC of 50 or less will result in disturbing impact sounds below.
With an IIC of 50 to 60 certain sounds in the spaces below may be audible, however with
IIC ratings of 60 or higher virtually no audible sounds from impact will be heard below.
Kinetics Type SR Floorboard is a proven tool in the control of
impact noise in condominiums, apartments, multi-family dwellings, commercial buildings,
and other areas where footfall and impact noise can be the cause of complaints.
Type SR Floorboard is a unique underlayment material which
substantially reduces sound transmission through hard surface floor systems. Ratings of
IIC (Impact Insulation class) of 50 to 65 have been achieved in typical applications,
compared with IIC-25 to 34 with conventional construction.
SR Floorboard is a 5/8" thick composite of high density molded
glass fibers separated by a rigid phenolic treated honeycomb core. It provides a system
which is stiff enough to prevent grout cracking in tile floors while being soft enough to
absorb impact loads.
