HD1045 Hush Multi Panel MF System Acoustic Solution

The HD1045 Hush Multi Panel MF System is ideal for adding sound insulation to a separating floor/ceiling in a conversion project where access is not possible to the floor above.

This full tested sound absorbent system is constructed from the ceiling so it does not require a floating floor in the rooms above. It complies with all UK Building Regulations - Approved Document E (England & Wales), Section 5 (Scotland) and Part G (Northern Ireland) and represents a versatile option for the acoustic treatment of separating floors in conversion/material change of use projects.

HD1045 is formed in the following way: 

• After the ceiling is removed, Hush Slab 100 Sound Absorber panels are installed within the joists. It is important to ensure the Hush Slab 100 is tightly packed between the joists and ensure there are no gaps.
• Then install the Hush MF Ceiling to the underside of the joists using the Hush Acoustic Hangers. A minimum 150mm void is to be created from the underside of the joists to the back of the ceiling lining.
• More Hush Slab 100 panels are then installed within the ceiling grid, again fitted tightly within the MF Ceiling System with no gaps.
• Hush Multi Panel is then attached to the underside of the Hush MF Ceiling System and overboarded with a layer of 15mm Fireline Plasterboard.
