Aluminum Framed Vacumn Bonded Lamination

I think the best construction method to prevent delamination is not the vacuum bonded process but a hung wall like a Newell or Newmar. Leaks can occur around any opening if not properly sealed but no delamination can occur because the walls are not laminated. Without getting too technical a vacuum bond is not the best way to bond skin to substrate, resin will boil under vacuum and bond lines are weaker than autoclave or press molding.
