For obvious reasons (27 pages) I haven't read every post here but I was wondering something...

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
