It is high performance acoustic foam. This provides a four-way effect like loss of sound energy on impact, deflection and change of direction, trapping of sound waves due to engineered cell orientation and absorption and barrier properties of the cells. It’s truly the best for noise control challenges.
It comes in three different standard sizes:
Thickness: 20mm, 25mm, 50mm
Sizes: 1m x 1m
» Auditorium and architectural acoustics.
» Industrial noise control application, Railways and metro coaches
» Genset and compressor enclosures. Concert halls
» Airports, hotels, commercial acoustics, HD home theatre.
» Light weight, long lasting and non-deteriorating
» Easy handling, applications and installation
» Low adhesive consumption, environment friendly
» Exceptional sound absorbent
» Dust and fiber free, fire retarded, excellent chemical, microbial & weather resistant.
