Ceiling System 2
Ceiling System 2 is the slimmest ceiling soundproofing solution suitable for soundproofing ceilings in hoses and flats needing to reduce airborne and impact sounds. With only minimal ceiling height loss, this ceiling sound insulation kit achieves a good level of noise reduction thanks to the combination of materials. Ceiling System 2 will increase timber ceilings’ mass and density, which reduces airborne sound transfer. Vibration and impact sounds are reduced due to the isolation created by the soundbreaker bars.
- Noise reduction against airborne and impact sound
- 58dB airborne sound
- 59dB impact sound
- 30-minute fire protection
- DIY soundproofing solution
- Part E compliant for separating floors
Noise reduction and decibels – A three dB increase is equivalent to halving the sound level. The higher the value for the airborne sound, the better the product performs. The lower the figure for impact sound, the better the product performs. Read the decibels explained guide for more help.
Ceiling System 2 Features
- DFM acoustic insulation – 100mm DFM acoustic insulation layer blocks and absorbs airborne sound transfer through the ceiling.
- Soundbreaker Bars – The separation, which is key to ceiling soundproofing, is created by fitting the soundbreaker bars acoustic hangers that reduce vibration through the structure of the building. The final layer of boards is applied directly to the soundbreaker bars.
- Noisestop 1+ panels – Supplied as part of this solution, Noisestop 1+ Panels combine a 12.5mm acoustic plasterboard and a 10kg mass-loaded vinyl sheet. The resultant panel blocks sound and reduces vibration through the plasterboard. Both impact and airborne sound are significantly reduced when the entire solution is combined.
- AC50 acoustic sealants – Apply AC50 acoustic sealant to the edges of the panels and the perimeter of the new ceiling.

Fitting Ceiling System 2
- If you are soundproofing an existing ceiling, you will have to remove it before fitting Ceiling System 2.
- Infill the joist cavity with 100mm acoustic insulation. Ensure the whole area is filled. Acoustic insulation slabs will friction fit between the joist if you cut them wider than the opening.
- Fit the soundbreaker bars at 400mm centres. The bars are attached to the ceiling joist by screwing through the pre-drilled holes.
- Attach the Noisestop 1+ panels to the bars by screwing through the boards into the wide corrugated flange on the soundbreaker bar.
- Use the acoustic sealant to seal the edges of the panels and around the perimeter of the ceiling.
- Install onto existing or new ceilings
- The system’s thickness from the ceiling joist is 35mm
- 58dB airborne sound
- 59dB impact sound
- 30-minute fire rating
- A competent DIYer can carry out the installation
Alternative ceiling sound insulation solutions offer different levels of soundproofing or another kind of installation method that might suit your requirements.
Wall and Ceiling Soundproofing
Make sure you are getting the right soundproofing for your needs. Understanding the most common types of noise and how to stop them will help you decide the right solution.
Different Types of Sound
- Airborne sounds – Conversation, TV noise and radios are examples of airborne sound. The best way to stop airborne sounds is to add mass/density to the walls or ceilings.
- Impact/vibration sounds – Footfall and moving furniture across a floor are examples of impact sounds. The best way to reduce these sounds is to create separation.
In summary, the best way to reduce airborne sounds is by increasing the mass of the area you would like to soundproof. Reducing impact/vibration sounds is achieved by creating separation within the structure.
Reducing Impact and Airborne Sounds
By following some of these steps, you will ensure you get the best level of soundproofing for your room.
- Mass/Density – Increasing the mass and density of the area you are soundproofing will block airborne sounds from transferring between rooms. You will increase the mass of walls and ceilings using materials such as soundproof panels or high-density acoustic insulation slabs.
- Separation – Incorporating separation within the structure will reduce vibration and impact sounds transferring between rooms. Achieve separation by building independent stud walls and ceilings. If you don’t have the space in the room, you can use acoustic clips and resilient channels to decouple the wall and ceiling.
- Absorption – Use materials that are going to absorb sounds. Acoustic insulation is suitable for sound absorption as it converts the sound waves into heat as it passes through the insulation. Dense mass loaded barriers will also dampen and absorb sound.
