HD1025 Hush System MF17 Acoustic Floor Solution - Acoustic Floor and Ceiling System

A fully developed economical sound insulation system used to form separating floor/ ceiling constructions in conversion, refurbishment and new build developments.

The HD1025 is a complete acoustic system that can be used as a flooring and ceiling solution. The system is a separating floor solution compromising of a Hush Panel 17 floating floor - a thin overlay board which minimises floor build where required without compromising performance – an 18mm chipboard deck and the Hush MF ceiling system.

To ensure acoustic insulation levels are maximised, the system also makes use of the Hush Slab 100 sound absorbing in-fill panels and Gyproc Soundbloc boards.

Hush HD1025 complies to all UK Building Regulations - Approved Document E (England & Wales), Section 5 (Scotland) and Part G (Northern Ireland)
