WHISPERMAT® - WM1 Barrier with foam decoupler
![[Product Image]](images/wm1.jpg)
|
Whispermat® WM1 is a barrier layer of Whispermat®
cured to a single layer of
Hushcloth® acoustical foam. When the Whispermat® is applied to sheet metal,
plastic or wood, the foam is exposed to absorb airborne noise. The barrier
then functions to both contain sound by increasing the effective mass to
the panel and to damp the structure borne resonant vibrations |
|
When the Hushcloth® acoustical foam is applied to the structure the Whispermat®
barrier is then
acoustically decoupled from the panel vibrations which creates a "Double
Glazing" effect and dramatically increases the sound transmission
insulation.
A facing can be laminated to the the exposed face of the Whispermat® barrier to increase both
durability, weather ability and appearance

Key Benefits
 | Unitary manufacturing process ensures intimate bonding between foam and
vinyl barrier material |
| Available in a wide range of weights, thickness and as sheets or rolls |
| Can be used as a carpet under-layment to increase sound isolation from the
space below the floor or deck. When moisture is of concern, as in the case
of a marine or off road application, closed cell foam can be used. |
