The panels are manufactured from imported Mineral Wool in a non-directional fibre orientation which allows a higher density, which traps sound waves and dampens vibration.  The panels repel water, are vapour permeable, and rot and mould resistant.  With such a demanding market products are continually improved and tested.


The Noise Reduction Coefficient (commonly abbreviated NRC) is a scalar representing of the amount of sound and energy absorbed upon striking a particular surface. An NRC of 0 indicates perfect absorption; an NRC of 1 Indicates perfect absorption. These panels are made with ridges fiber cavity that has a 0.95-1.05 NRC rating.


Acoustic foam bases products range between 3" Thick = 0.45 and 4" Thick = 0.65 NRC Rating.Similar products are usually manufactured from foam which does not absorb any low frequency sound waves or bass with a frequency less than 200 Hz and the density does not dampen higher frequency sounds.
