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||Ease of Fit||Airborne (Dntw+Ctr)||Impact (Lntw)||Approx Price/m²||Floor height gain||Ceiling height loss|
|Regulation E Requirement (Conversions)||-||43dB||64dB||-||-||-||-|
|Isosonic type C||Original ceiling retained, Suspended Ceiling added, Minimal floor work||51dB||55dB||£29.95||Existing floor + 6mm acoustic mat+ hard flooring surface of choice||81mm||MORE|
|MF Dec18||Floating floor, Under floorboard access, Suspended ceiling.||49dB||49dB||£39.95||Existing floor + 26mm Monarfloor Deck 18||41mm||MORE|
|MF DEC 9||Floating floor, Under floorboard access, Suspended ceiling||48dB||48dB||£46.50||Existing Floor + 17mm build up from existing flooring surface on average 36mm from joists||41mm||MORE|
|MF TRI DEC||Floating floor (replacing existing floorboards), NO suspended ceiling required *.||46dB||56dB||£43.60||35mm build up from joists. Note with Lath and plaster ceiling no resilient bars need adding||0mm||MORE|
|Independent Ceiling||New Independently joisted ceiling Required||50dB||42dB||£28.00||No Work to floor required||180mm (typical)||MORE|
|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||MORE|
|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|
