HD1016 Hush System HF25

A fully developed economical sound insulation system between separating floors for use in refurbishment projects using timber joists.

It is principally for use in refurbishment and conversion developments where a joisted structure is in place. And as HD1016 is tested as a complete system, it is designed to delivers on its promise.

Product data sheets can be found in the ‘literature’ section.

HD1016 works by providing a floating floor offering maximum sound insulation – it ensures that the cavities between the floor joists are filled with high grade absorption materials, in conjunction with a resilient bar solution.

Hush products combine effectively to achieve the excellent performance standard. Hush-Felt 25 Resilient Strip and Hush-Slab 100 sound absorber are key, reducing impact and airborne sound transmission, to contribute to the high performing acoustic solution.

It is fully compliant with all the UK Building Regulations relating to sound insulation - Approved Document E (England & Wales), Part G (Northern Ireland) and Section 5 (Scotland). It also offers assurance with respect to fire safety with a 1 hour fire resistance at ceiling level.
