SOUNDPROOFING ABSORPTION MATERIALS


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:

  1. Foam Pad - composit products that consist of acoustic foam laminated to vibration damping sheets.
  2. Film Faced Absorbers - a range of oil and waterproof noise absorbers
  3. Trim Foams - provided with decorative vinyl facings
  4. Acoustic Foam - a range of sheet foams produced to two different flame retardent specifications.
All supplied self-adhesive if required

Acoustic Foam and Foam Pads SA12, SA25, SA12SA, SA25SA

Applications

Applications for acoustic foam and foam pad are found in a wide variety of noise control treatments such as machinery enclosures, plant machinery and cabs, office equipment and domestic appliances. Acoustic foam is normally employed as an internal lining to machinery guards or enclosures. Foam pad is used when additional vibration damping is required to reduce noise produced by resonant vibration of metal panels.

General Description

The absorption element of acoustic foam and foam pad is provided by a special grade of polyurethane foam produced to an exacting structural specification. The vibration damping sheet of foam pad is provided by a laminated backing of damping sheet type SD1

Fire Retardent Acoustic Foam SA12(FR), SA12(FR)SA, SA25(FR), SA25(FR)SA

Applications

Fire 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.

General Description

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.
