Noisedeck 28 is an acoustic floating floor soundproofing solution installed over floor joists, reducing sound transmission between floors. It comprises an 18mm P5 V313 moisture resistant interlocking chipboard bonded to a 10mm recycled PET mat. When installed as part of a complete sound reduction system, it enables a timber floor to meet the sound transmission regulations of Approved Document E 2003 and subsequent amendments in 2004, 2010, 2013 and 2015.

Fitting Noisedeck 28
- Ensure the sub-floor or joist is suitably even, clean and dry to allow the Noisedeck 28 to be laid flat.
- You should install perimeter isolation tapes on the edges of the walls to isolate the boards from the walls.
- Commence the installation of the flooring from the furthest point from the entrance and try to avoid off-cuts of less than 200mm.
- Noisedeck 28 is laid in a broken brick bond pattern with the tongue and groove edges glued together. Avoid mechanical fixings into the joist.
Direct to Joist
Separating Ceiling to Meet Part E Building Regulations
Comply with Part E Building Regulations by installing the Noisedeck 28 using the following ceiling construction method. Fit the Noisedeck 28 directly over the floor joist or as an overlay system if the floor is in place.

Floor 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 floating floor soundproofing 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. Use acoustic underlays or floating floors to absorb footfall through timber and concrete flooring.
