ISO Hanger System
This system is one of the best options if the height of the room is sufficient to lower the ceiling by 100mm. This is one of the cleanest systems to install because the original ceiling remains intact. The old ceiling will be left on the first layer of protection against airborne noise with the hangers attached to the existing joists. Through these hangers, beams are attached which form the basis for a new soundproof ceiling. We place resilient bars on the beams to provide additional impact resistance. The system also uses mineral acoustic wool between the new frame structure and two layers of 19 mm and 12.5 mm acoustic plasterboard. The circuit and all joints on the 1-layer acoustic plasterboard will be sealed with acoustic silicone.
