    Part E approval documnet

    I am planning on convwering my property into 2 flats. I have some experience as I did this quite a few years ago, but before Part E. Then a sound test wasn't needed. I have building regs and planning approval. The specifications for the building regs, regarding sound proofing, require me to lift up my floorboards and replace with t&g chipboard. I don't want to rip up the original floorboards. I am looking for a cost effective floor sound proofing method thst doesn't need the floorboards to be ripped up. There will be ceiling proofing underneath i,e resilient bars 2 layers plasterboard etc.
    Also Yje link through the Planning Portal doesn't work. Is there another link?

    http://www.planningportal.gov.uk/upl...F_ADE_2003.pdf works fine for me.

    I am assuming the property is timber framed. I would have thought a Celotex insulation board above the ceiling space would be sufficient, providing it gave enough protection to the structure??
    [I]The opinions I give are simply my opinions and interpretations of what I have learnt, in numerous years as a property professional, I would not rely upon them without consulting with a paid advisor and providing them with all the relevant facts[I]

      You should be able to relay the existing floor boards - assuming you're using the British Gypsum Silent Floor System - and fix them to the isolating channels / sound board. Adding extra mineral wool (150mm instead of 100mm) insulation should compensate for the additional gaps between the floor boards.

      Workmanship is far more important that the system used though. Properly sealing and/or separating at junctions, abutments etc... will be far more effective.

      I am assuming that who ever has done the specification for you has seen the property and has provided you with a suitable design. Sounds like you need to go back to them to adapt this design to retain the floor boards.
      There is always scope for misinterpretation.

      If my posts can be interpreted in two ways, one that makes you feel angry and one that doesn't, I meant the latter.

      Everyday is an opportunity to learn something new.

        We used an approved system floor in our 3 flat conversion.

        We left the original floorboards in place (they were in good condition, fitted well and I saw no reason to pay for them to be ripped up and dumped!) and added an approved dense chipboard floor with resilient backing over the top. The joist space was filled with dense rockwool and the underside was fitted with two layers of accoustic plasterboard attached to resilient bars. In fact one specialist suppliers stated that leaving the original floorboards with all damage/gaps repaired would add to the sound proofing.

        It passed the 'sound test' with flying colours!

          Keeping the floor boards floating ceiling no floor works?

          Tipper interesting you didn't remove the floorboards. We are midway through a 3 flat conversion (so I may be back asking more questions as you seem to be the most recent person to have completed a 3 flat conversion.

          We are trying to comply with the soundproofing without losing headheight.

          1. Can you confirm that you did your rockwool, doubleboarded acoustic plasterboard with resilent bars for the ceilings BUT for the floor did you actually seal between floorboards before chipboarding over - in an ideal world don't really want to have to touch the floors but we are faced with either screwing down the boards properly and sealing and using a really good acoustic matting instead of underlay or removing boards and gyrocing over but thats a pain from a future plumbing leak perspective.

          There was a post sometime ago by cdr karen who said that she passed with just a floating ceiling.

          Finally did you have to soundproof your communal corridors and stairwells? Were these actually tested or were the habitable rooms tested?

          Apologies for so many questions first up - its a minefield!

              Sorry not been on recently.

              The floorboarding was T&G so in the main didn't require sealing but any missing bits or damage was repaired but not actually sealed either.

              It was special acoustic heavy chipbaird that was laid over and it was about 25mm thick with a resilient backing. This was also T&G and was a floating floor but sealed around the walls IIRC. The skirtings had to be isolated from the floating floor also. We did this by using sponge filler strip around the edge which was turned over the edge under the skirting. This was further enanced by wrapping the laminate floor over the edge under the skirting too, but only because we were using the laminate floor.

              No communal parts as all flats have separate entrances due to the terraced layout of the site.

              Because the 2 intermediate floors were all done to the same spec/system the sound test was agreed to be upwards and downwards between each flat but only between 3 representative rooms, ie one on each floor (3 storey build with ne flat oper floor)

              Incidently I did have to cut into the floor to repair a water leak (faulty fitting, not my plumbing skills!) and made sure I sealed the repair cuts properly with acoustic mastic.

              Hope that helps.

              BTW we used standard acoustic floor/ceiling materials that came from Sheffield Insulations. Can't remember what the Brand name was, could be Karma?
