Reverberation within the room is caused by sound bouncing off the hard floor, ceiling and wall surfaces. In order to reduce reverberation, these surfaces need to be treated with sound absorbing materials. Boral offers a range of wall and ceiling lining materials with high sound absorptive properties.

Boral Echostop perforated plasterboard is available in three attractive designs, and can be used on both ceilings and walls to provide Noise Reduction Coefficients up to NRC 0.80.

Boral also offers a complete ceiling tile system with an extensive range of acoustic ceiling tiles providing Noise Reduction Coefficients up to NRC 0.95.
