Acoustic Ceiling Pads should be placed loosely over the back of ceiling tiles, ensuring complete coverage without compressing the material. Avoid blocking air vents, lighting fixtures, or other ceiling services.
Supplied in compression-packed polythene bags for ease of handling. Store in a dry, covered area, off the ground, and away from moisture.
Wear appropriate PPE including gloves, long sleeves, and a dust mask when handling. Refer to the product Safety Data Sheet for full details.
Rock mineral fibre is highly effective at absorbing airborne sound, reducing reverberation time within a room and improving overall acoustic comfort. When placed above suspended ceiling systems, Acoustic Ceiling Pads act as an additional barrier to airborne sound, minimising room-to-room transmission through the ceiling void.
Laboratory testing shows that a 50 mm thick 45 kg/m³ pad can achieve a Noise Reduction Coefficient (NRC) of up to 0.95, making it suitable for applications where speech intelligibility and privacy are critical. The reduction in sound transmission between adjacent rooms can be as high as 10–15 dB, depending on the ceiling tile type and installation method. Used in conjunction with a suspended ceiling grid.
Typical room to room reduction:
38dB (50MM pad located over suspended ceiling grid)
32dB (25MM pad located over suspended ceiling grid)
These properties make the Acoustic Ceiling Pad particularly effective in open-plan offices, call centres, healthcare facilities, classrooms, and other spaces where control of both internal acoustics and sound leakage is essential.
