How important is the sealing technology used to process the vapor barrier?
It is extremely important when comparing cover manufacturers that you look at their sealing technology. Our manufacturer has invested in a very expensive, computer-controlled pneumatic impulse sealer to ensure that the vapor wrap is sealed. This machine puts a 1/4″ weld on each seam compared to other manufacturers that use hand-sealers that seal with a nicron-wire razor thin seal or, even worse, manufacturers that tape their vapor barrier shut.
