Anyone have any experience w/ these? I get the concept, but it Seems they'd be too leaky (shimmed air space above and below) for Northern climes.

Thanks

i just use a 1-2inch ventilated feeding shim then a home made quilt box ( basically a medium super with window mesh on the bottom then filled with wood chips/shavings although some people use sack cloth) on top of the feeding shim.
Does the same job but cheap.
