A) Acoustic Hanger Type C
B) Resilient/Sound Breaker Bars
C) Independent Ceiling
*"Results may vary due to flanking noise and structure"
- Joists are allocated through existing ceiling
- Acoustic Hangers are then fitted to existing joists 600mm centres
- New 50mm batons are fitted to the acoustic hangers
- 19mm sound plank is fitted to the batons
- All the joints and edges are then sealed with acoustic mastic
- 12.5mm sound shield plaster board fitted as final layer
- 3 Inches of ceilling height loss
- 17db Improvement in Air Borne noise*
- 19db Improvement in Impact noise*
B) Resilient/Sound Breaker Bars
- Old ceiling would need to be removed or 50mm batons fitted to the joists
- If ceiling removed 100mm rock wool fited between exposed joists
- If ceiling left 50mm rock wool fitted between exposed joists
- 19mm sound plank fitted to resilient/sound breaker bars
- All joints and edges sealed with acoustic mastic
- 12.5mm sound shield plaster boards fitted as final layer
- If old ceiling removed 1 inch ceiling height loss
- If batons fitted 3 inch ceiling height loss
- 17db Improvement in Air Borne noise*
- 16db Improvement in Impact noise*
C) Independent Ceiling
- New joists of sufficient size to suspend a ceiling mass of 23kg/m² need to be installed typically with 400mm centres
- 100mm of RS60 rock wool to be inserted into between new timber joists
- Resilient/Soundbreaker bars to be fitted to new joists
- 19mm sound plank to be fitted to resilient/soundbreaker bars
- All joints and edges to be sealed with acoustic mastic
- 12.5mm sound shield plaster board to be fitted as final layer
- 6-7 Inch ceiling height loss
- 23db Improvement in Air Borne noise*
- 24db Improvement in Impact noise*

FAQ
What happens to the lights in the ceiling?- All existing lights will be re-fitted at no extra cost.
- There are many acoustic/fire rated spot lights on the market which are designed to let less noise to travel through the light fitting, but by keeping the insulated ceiling in tact is always advicible
- As many properties are different and there are many factors which influence the performance of any system such as "Flanking noise" internal "Stud Walls" an average of 10db will give you upto 50% (Half) noise reduction.
