I used acoustic insulation as i wanted to sound proof my office from the noise downstairs. This was rockwool acoustic insulation but it also has thermal qualities.
Hi Marcus, you could try and wedge it into place as it is quite rigid. The alternative option would be to cut come thin strips of wood (ceiling battening or 2"x1") and wedge it between the joists to support the Rockwool sound insulation.
great video ! did it make much difference ? how long did it take from start to finish ? ... maybe rename video acoustic flooring install , might get more hit s : )
+Neil, thanks for your comment! it's made a massive difference. Including lifting the floor, it took about half a day. I think your right about re-naming the video! 😀
I have live in a flat and apparently the insulation is Ash. It does nothing. How necessary is it to clean out the space before installing the rockwool. My plan had been to just put it on top
Hi, unfortunately, i wouldn't know without seeing it. If it's a ground floor flat, you need to take into account damp. However, if it's upstairs, it shouldn't be a problem!
Hi, mine are led and firerated and dont generate much heat, so i left a gap around the sides . The top layer of insulation went over the top but didn't touch the spotlights. Hope that helps!
Hi, my floor space was 170 mm deep, and the insulation was 100 mm deep, so i ended up with a gap of around 70mm from the top of the insulation to the underside of the floor boards.
@@FixitwithFowler I have a choice between filling it up fully to the top or leaving the gap. Just trying to understand if I should leave some gap for air circulation

I appreciated you taking the time and effort to give us a view under the flooring.
No problem, this sound insulation has made a massive difference in my office! Thanks for your comment!
How heavy is the double layer of insulation?
We have an old asbestos ceiling are we are afraid it will not hold the insulation.
Does it help with thermal insulation or just acoustic ?

Great video buddy. Planning on putting this in, but have no downstairs ceilings (ripped them all down), so need to put in some sort of netting first.

@@FixitwithFowler thanks for the reply buddy. I will definitely try that.

Hi, just a question is it ok not to use membrane?
And do you leave a gap where it’s outside wall?
Why would you need a membrane? No I didn't leave any gaps as the sound can travel straight through!

Thanks yes it's an upstairs flat :)
So long as you can achieve 100mm of insulation it will definitely make a difference
Hi what if the room below has spot lights in the ceiling do you need to box them off?

Hi really appreciate your reply. Yes mine are LED and fire rated as well again thanks antony @@FixitwithFowler
@antonytompkins5486 No problem, let me know how you get on!
Should I leave a gap for air circulation?
Hi, my floor space was 170 mm deep, and the insulation was 100 mm deep, so i ended up with a gap of around 70mm from the top of the insulation to the underside of the floor boards.

Hi, yeah sorry. I would leave a gap to allow the wooden floor to breathe. Hope that helps!
@@FixitwithFowler thank you
Was a bit loose lol
It's perfect for this application 😍
Just so you know all cables in contact with insulation are de-rated by 50% haha
