Sonoguard™ Sound absorption materials control airborne noise by reducing the reflection of sound from boundary surfaces thus reducing the overall noise levels. The complete range of our sound absorption materials include the following:
Sonoguard™ Fire retardant Acoustic Foam is based on a remarkable cellular bi-elastomer which is incapable of supporting combustion and will protect other materials from a wide range of dangerous ignition sources. The material is soft, pliant and resilient therefore making it easy to fit, but hardwearing when in place.
Fire Sonoguard™ Retardant Acoustic Foam is totally non-flammable. It can be used in the same way as ordinary acoustic foam but is far more versatile. It is of particular use in heating and ventilation ducts, machinery guards and enclosures and even buildings. It also offers good thermal insulation and has the advantage over other types of insulation of not losing dust or fibre particles.
