Fair-faced Class D sound absorbing block
Alphacrete® Acoustic is a revolutionary sound-absorbing masonry block developed to help control acoustic reverberation.
Achieving the right reverberation characteristics is critical to the acoustic performance of an interior space. Alphacrete® Acoustic has been specially developed to offer higher levels of sound absorption than standard masonry block – providing a simple and cost-effective solution to reducing airborne noise and excess reverberation that reduces speech intelligibility and acoustic performance in conventional constructions.
Alphacrete® Acoustic is the only independently-tested masonry block available that meets both the acoustic performance standards for the Department of Education’s Priority School Building Programme (PSBP) and Class D sound absorption levels to BS EN ISO354:2003 ‘The Laboratory Measurement of Random Incidence Sound Absorption’.
Available in both Athena and Corinthian finishes, specifiers and contractors can choose from an extensive choice of colours and special detailing shapes to flexibly create projects with true visual impact.
AG developed the Sporting Green colour to help achieve the requirement as prescribed by Sport England in their design guidance notes (section 5) February 2011. AG’s Sporting Green colour will give sufficient contrast against sporting accessories.
Alphacrete® Acoustic block has been developed using a special aggregate mix and altered geometry. It has been comprehensively independently verified to produce significantly improved sound absorption performance over standard blocks.
A comprehensive selection of special shapes are available for detailing purposes.
Alphacrete® is produced in the UK from locally sourced materials and manufactured with 100% harvested rain water and 100% renewable energy in the production process.
