Barrier
materials with decoupling layers or underlayments can be used
to control floor to floor sound. In addition to reducing airbourne
sound, the separated barriers help to reduce the sound energy
that can get into the structure and travel to other parts of
the building.
These treatments can be particularly useful in buildings and
homes where ceilings are finished. It is a common way to control
unwanted sound in multi-floor homes that are converted into
separate apartments. |

BM
-1C is a barrier material within an attached foam
decoupling layer that can be placed directly on the floor then
covered with carpet. The barrier lays flat and does not need
to be glued or fastened to the floor. The sound transmission
loss that is a achieved is significant compared to other methods
that usually require a great deal more mass in the assembly. |
Plain barrier material like the
5
B-OB can be used in conjunction with Duracoustic
underlayment. This combination increases transmission
loss and provides impact isolation to reduce the sound of people
walking or moving around overhead.
The Duracoustic
is laid out on the floor with no installation requirements other
than taping the seams. The
5
B-OB barrier is rolled out on top – perpendicular
to the runs of Duracoustic
( seams also taped) carpet is installed directly over the
decoupled barrier to complete the floor finish. |
