I'm planning to build my traps soon as I have a load of Rockwool left over from a thermal insulation job. I was planning to use aluminum to build my frames. Thin U-channel stuff to cover the sides (and a small bit of the front and back) to ensure everything stays in place (they will be getting transported between my two locations every so often) and a piece of hardboard on the back to staple my fabric to. Is there a problem with me doing this? Do I need to keep the back open? Also, do I have to take the foil off of the back? Is there a problem using metal instead of wood?
I never even considered these issues until about 5 minutes ago when I thought about air going THROUGH the traps, with hardboard on the back, how is it getting through. Will my design be better if I keep the hardboard to a minimum (lots of large holes)?
Thanks in advance thumbsup |
you want as much insulation exposed as possible, so yes, def. want the back open...
if you have foil on the rockwool, it should be facing the front not the back. people use the foil so they dont make room too dead.
wood or metal is a matter of personal preferance, and ease of construction. I like wood better, easier to make the frame with IMO and gives you something to staple the fabric onto..
You can makes holes/design into the sides of the bass trap, makes them more efficient...whether it be metal or wood....
