DeTomaso Mailing List: January 99, Message #245

Richard,
When double pane windows are made for your home the mfg will sometimes
replace the air between the glass with an inert gas. I think they do this to
keep the windows from forming condensation between the panes. This would be
a major bummer if your back window fogged up and you couldn't do anythink
about it.

Cary
