Kinetics
Model SR Floorboard is a unique underlayment material which substantially
reduces sound transmission through hard surface floor systems. Acoustical
Lab Ratings of IIC (Impact Insulation Class) 59 to 65 have been achieved
in typical applications, compared with IIC-25 to 34 with conventional
construction.
Model SR Floorboard is a new concept in the control of noise in condominiums,
apartments, multifamily dwellings, commercial buildings, and other areas
where footfall and impact noise can be the cause of occupant complaints.
SR Floorboard is a 5/8" (16 mm) thick composite of high density molded
glass fibers separated by a rigid phenolic-treated honeycomb core and
provides a system which is stiff enough to prevent grout cracking in tile
floors while being soft enough to absorb impact loads.
Application
Many occupants have a preference for hard surface floors such as ceramic
tile, quarry tile, marble, hardwood flooring, engineered floors, or vinyl
tile. Without carpeting to cushion footfalls, impact noise will be heard
clearly in the occupied spaces below.
Many localities have adopted building codes which require minimum IIC
and STC ratings for floor/ceiling systems. An IIC of 50 or less will result
in disturbing impact sounds below. With an IIC of 50 to 60, certain sounds
may be audible in the spaces below.
Acousticians familiar with noise issues in high end condominium buildings
often recommend a lab tested assembly with ratings in the 55 to 60 range
to minimize occupant complaints.
For use with either wood frame or concrete structural floors, Model SR
Floorboard can be installed with a 1-1/2" (38 mm) reinforced mortar bed
or 7/16" (11 mm) glass mesh mortar units to provide a stable underlayment
for ceramic tile installations.
Model SR Floorboard systems have successfully met the requirements for
durability in accordance with ASTM C627 as tested with ceramic tile finished
floors.
Benefits
- SR Floorboard will withstand live loads up to 1000
psf
- SR Floorboard maintains its strength even when wet
- SR Floorboard cuts easily using standard construciton
knife
- Floor compsites with finished tile flooring can be
under two-inches (2") high
