Acoustiblok Sound Isolation Material has been extensively tested acoustically by independent accredited facilities and is approved for use in more than 300 U.L. rated construction assemblies from typical stud partition walls, party wall and commercial solid wall construction.
An STC (Sound Transmission Class) rating is a single member rating that is used to specify and compare different partitions according to the reduction in noise levels that the partition or construction provides. As a general rule, the higher the STC rating, the better the partition’s acoustical performance. Extended frequency testing shows that a single layer of Acoustiblok 3mm Isolation Membrane installed into a standard 75mm stud wall provides an impressive Sound Transmission Class of 53dB (23dB reduction at 40Hz).
In addition, Acoustiblok is a self extinguishing material while many similar looking products are rubber based and combustible. Acoustiblok is also rated with the highest score possible (10) for protection against mould and mildew growth, is non hazardous, odour free and will not diminish in performance over time.
