Acoustic cradle used to create a unique self-levelling support system for decking areas. The unique patented product has been fully assessed and tested at Swansea University Materials Centre of Excellence and conforms to the loading conditions for the flooring as laid down in BS 5399.

The cradle is designed with a cellular rubber base support to help spread and soften impact noise, as well as the impact of the imposed load.
