Ceiling Solution 3
Independent Ceiling
If you wish to buy this solution online we can calculate the materials you need.
Where the impact sound from above is very bad, this is a soundproofing choice worth considering. Typically hanger systems and resilient bars are not able to cope with heavy vibration, the type that you might experience with young children thundering around in rooms above you, which might even result in your windows shaking. If you are able to lose ceiling height, which, depending on the span of your room could be up to 225mm (7-9 inches) then this will be the best performing system.
The independent ceiling comprises of the following system.
New Ceiling joists of sufficient size to suspend a ceiling of mass 23kg/m2 need to be installed typically with 400-500mm centres. This information can be obtained from building regulations.
The materials required are the same as those found in the resilient bar ceiling solution.
These are resilient bars, acoustic mineral wool, friction fitted between the joists and a double plasterboard ceiling ideally of 19mm and 12.5mm SoundBloc plasterboard.
Important note on recessed lights
If you are adding recessed spotlights in this ceiling you will need to add an acoustic fire retardant light hood to each light, otherwise your soundproofing efforts will be severely compromised due to the hole you have created. These can be purchased from our on-line store.
