This product is particularly effective when applied to single skin walls such as block work, brick or studwork partitioning.

Traditional methods of applying insulation to reduce airborne noise transmitted through existing walls took up approximately 150 mm of room space using timber studwork and mineral wool infill.

Significant improvements in sound insulation can now be achieved with the loss of less than 50 mm of room space using 20 mm thick CAD20-WP insulation and two layers of plasterboard. Even greater noise reduction can be obtained if the treatment is applied to both sides of the wall.


  • Specifically designed to absorb and reduce airborne noise through party walls.
  • Suitable for domestic party walls and stud partitions.
