Alphacrete Acoustic Block®


Alphacrete Acoustic is a unique masonry block specially developed to help control reverberation time. Achieving the right reverberation time is critical to the acoustic performance of that space. Alphacrete Acoustic has been specially developed to offer higher levels of sound absorption than standard masonry block whilst maintaining the high quality, prefinished, low maintenance appearance of the Alphacrete range.

A&G’s Alphacrete Acoustic is the only independently tested masonry block available that meets the newly published acoustic performance standards for the Department of Education’s Priority School Building Programme (PSBP).

The only fair-faced, certified Class D sound absorber independently tested to BS EN ISO354:2003 ‘The Laboratory Measurement of Random Incidence Sound Absorption’.
