Hybrid Iso Hanger System
Airborne and Impact Noises. Very robust solution for people wanting maximum soundproofing in 4 inches. This is a Iso Hanger system with an additional layer of 100mm Acoustic mineral wool installed between the exposed joists after the original ceiling has been removed. The main aim of the extra mineral wool is to start absorbing the noise as close to the source as possible. It will reduce “the speaker box effect” that the cavity between old ceiling and floorboards creates. The Isonic Hangers are fixed to the exposed joists. Batons are fitted through these hangers to form a base for the new soundproofed ceiling. We incorporate resilient bars onto the batons for added impact performance. This system also utilise acoustic mineral wool between new frame structure and two layers of acoustic plasterboard 19mm and 12,5mm. The perimeter and all joints on 1st layer off board will be sealed with acoustic mastic.
