Hi Cojo, have a question for you, read as far as your second set of traps which look great, am going to copy you, but hey imitation is the sincerest form of flattery and all that
I'm in Copenhagen so figure I can source pretty much the same materials as you, and the price certainly sounds good.
Any chance you could list the names/brands of the materials you used - brand and exact type of mineral wool especially, and type of wood (if it matters), then I can find some dealers. I've not really done any furniture style DIY before and would like to give it a go, but haven't a clue as to this stuff.
Also, I've seen many traps that extend all the way from floor to ceiling, but yours look quite short, does it matter? And if they're only half the height of the room, should they be hung up from the top or stand on the floor?
How did your response tests turn out in the end, or did you get side-tracked with all that single malt?
I'm gathering that a 6" deep trap in each of the 4 corners, plus a 2" deep cloud and 2 x 2" sides should be the minimum..?
Thanks in advance for some pointers!
