Hush Acoustic Decking Cradle


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.

It is the ideal solution for supporting timber joists for decking purposes on balconies and roof terraces. The unique recycled plastic body is designed to support joists keeping them off the roof deck and away from the drainage of the roof. 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.
