  • Delivery direct to your door within 48 hours

 
  • A very effective solution for those with 7 -9 inches to spare

  • New joists will be installed to effect complete separation

  • Separation form old ceiling and extra resilience ensure maximum soundproofing

  • Online calculator will work out your exact requirements

 
Independent Ceiling Soundproofing - How it works

Where the impact sound from above is very bad, this is a ceiling 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 soundproofing system comprises of the following.
For customers looking to insulate noisy pipes please see our acoustic pipe wrap.

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.

Soundproofing fitting instructions

 

 
Sound proofing basics

When soundproofing a ceiling it is necessary to improve three components.

1) The mass of the wall- This we achieve by adding by adding acoustic plasterboard and high density products. In addition to this mass the independent ceiling achieves complete separation fro the vibrating surface. So vibrational sound through the ceiling is avoided.

2) The Resilience of the ceiling- This is the springiness of the new ceiling is key. Although you have removed direct vibrational contact the sound waves will still be passing in an airborne way. The resilient bars will mean the attached plasterboard mass performs up to 35% better.

3) The sound "absorbency" of the veiling. By adding different components the sound gets trapped more easily within the ceiling; here we prescribe the 100mm AMW 60. This is a key component in absorbing what is often low frequency impact sound.

 

Understanding Performance

To the right you will see a performance table.

The total performance which is normally quoted on most sites refers to the performance of an average wall with soundproofing materials added

We also give an indication of performance uplift. Remember that every 10dB of performance uplift corresponds to roughly a 50% improvement in the performance of the wall. So 20dB would indicate a 75% Improvement over and above the original wall.

The action of the SBx board materially improves the performance of all solutions with particular emphasis on airborne sound. Improving it by around 8db over and above the stated performance.
*Please note figures stated for total system are based on a a timber joist ceiling floor construction with 200mm joist. The figures are Lab figures and are Ctr corrected. So are not comparable to regulation E Systems. The improvement figures state improvement over a regular timber floor and plasterboard ceiling.

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. Spotlight hoods
