> Are those the foil sheets that basically vaporise the object (and part of the shield) so it won't penetrate the inner hull? Yes. Orbital hypervelocity impacts basically vaporize immediately on hitting anything, so you can offset a thin material in front of what you want to protect and cause any incoming object to turn into a cone of many much smaller objects which are less likely to penetrate the main hull.
