Soundproof Ceiling Solutions


The floor ceiling divide is usually the single biggest expense when soundproofing to regulation E standard. It is important to understand that regulation E soundproofing solutions can be achieved in a number of ways and the acoustic solution you ultimately choose may not just be driven by materials cost, but by ease of fitting and by floor ceiling height constraints . For overall value and simplicity of fit we would recommend the Isosonic hanger solution.

Please click on any of the following solutions below to see more information about that solution. All systems have been tested by manufacturer to regulation E standard and the test results are listed here. For ease of fitting and overall cost we recommend the Isosonic hanger solution listed below.

System Notes on Solutions Relative Labour Intensity  
In a typical conversion this the preferred choice is to keep the existing ceiling in place, the new suspended ceiling is attached via hangers screwed the ceiling. The simplicity of the work on the floor above and the lack of need to add mineral wool beneath the floor boards reduces considerably the labour associated with this solution Low/Medium
MF Dec18 Being a floating floor system it tends to perform a little better from the impact sound perspective. Where flanking sound issues or poor intrinsic performance of the existing floor is suspected this solution will offer extra impact sound performance. High MORE
MF DEC 9 The choice of Monarfloor deck 9 over deck 18 is usually driven by the desire to minimise floor height build up High MORE
MF TRI DEC In a situation where an existing lath and plaster ceiling is present or the desire to keep ornate coving or period features is important then this solution is ideal as only work on the floor is required to achieve Regulation E success. Please note this solution will not be adequate with a single plasterboard ceiling. Low MORE
Independent Ceiling This is a good choice for those who can afford to lose around about 200mm+ ( 8 inches+) of ceiling height. Note that for larger span rooms the independent joist may have to be thicker than the 125mm joists assumed here. Medium MORE
