Anyone ever cut holes in their ceiling and filled the loft with insulation/mineral wool?

Hi all

Just a thought really.....

I'm converting my spare bedroom and wondered whether this would be a good idea..... cut large holes in the plasterboard ceiling and put a mega depth of mineral wool in the loft, to form a bass trap. This would be in the back half of the room, as I have clouds already in the front half (needed to deal with first reflections).

I have not come across many people doing what I propose (the holes/insulation), but cannot see why it would not work.

If I went for it, should I make the holes as large as possible to allow the LF waves to reach the mineral wool?

Also, from a DIY point of view would it be a real bngger to put things right when we come to move?

Cheers

Yep, I did this with my first commercial studio back in the 80s. Loads of peg-board with rockwool behind it, including a lowered, angled ceiling. I also filled big cardboard boxes with rockwool, cut a big hole in one side of the boxes and placed these hole-down against the peg-board ceiling.

It seemed to work well at the time, but I was just wild-guessing, so have no idea how effective it really was!

To remove it all would have left a hell of a mess, but we were in commercial property that was later demolished!

Once you start cutting holes in the ceiling it won't be as effective at stopping sound from getting out. If soundproofing isn't an issue then it might work.
