Composite Foam
|
|
|
|
Composite foams combine
BlockAid® Barrier, acoustical
foam (either
Polyurethane
or
FireFlex™)
and a ¼" Foam/Barrier Decoupler. Composite Foam
is used when you need increased noise
absorption, sound transmission loss and/or
vibration damping. Composite foams can be used
to create soundproof enclosures for machinery
and noisy equipment. |
