It's basically double glazing, but with a vacuum, and a spacer to keep the glass apart. There's only a 1mm gap, as a larger gap is no advantage with a vacuum. The spacer was a grid of regularly spaced 1mm balls (or so it appeared), so it's not invisible. The glass panes can be thinner too, as they act together as one. This means it can be used in places which can't take even the thinnest double glazing. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

It's basically double glazing, but with a vacuum, and a spacer to keep the glass apart. There's only a 1mm gap, as a larger gap is no advantage with a vacuum. Just 0.2mm in some Pilkington stuff The spacer was a grid of regularly spaced 1mm balls (or so it appeared), so it's not invisible. The glass panes can be thinner too, as they act together as one. This means it can be used in places which can't take even the thinnest double glazing. Pilkington claim just 6mm overall. I'd need to win the lottery first as it ain't cheap but I know someone whose been looking at it as he reckons it his best bet to get double glazing into a listed property (or at least where period glass has already been replaced by float). And I'm told you can tell when it leaks as its balls drop. I don't know if it then starts squeaking funnily as well when washed:/ -- Robin reply to address is (meant to be) valid |
