would these work as basstraps?

Somewhat but foam really isn't nearly as effective as fiberglass or cotton. You could DIY something cheaper from either of those that would work better.

thanks for your input! i am very sceptical against fiberglass since this is in our living room and fiberglass or Rockwool stuff and kids is not a good kombination...

cotton might be a good alternative. not quite sure where to get it, though. Old clothes would do the trick, right?

old clothes will do something but who knows what. Acoustic cotton is available - though not sure where in Europe.

could you name a few producers of acoustic cotton?

I wrapped the fiberglass insulation(pink fluffy) with cotton batting. I then put some homemade diy frames over them wrapped with more cotton batting and burlap. I don't seem to be getting any fibers released into the air from the fiberglass as far as I can tell. I have bad allergies and am easily affected by dust and the like and have a wife and two kids and none of us have ever noticed or complained about it. The cotton batting seems to hold the fibers at bay pretty well IMO.
