vapour than Typar, which are the only two choices available
locally, but I'm building a sugar shack, which as its
primary function is to dissipate a tremendous amount of
water vapour. I don't want the water to condense on the
ceiling air barrier, otherwise it may drip back into the
syrup. What's the absolute most vapour-permeable air
barrier on the market, including those esoteric European
membranes?<o:p></o:p></span></p>
