What insulated glass unit means
An insulated glass unit is two or three panes of glass sealed around a spacer with air or gas between them, the glass package in most modern windows.
Also called IGU, double pane, dual pane.
Where it matters on a glass job
A failed seal shows up as fog between the panes. Replacing just the IGU in a good frame is often far cheaper than a new window, which is a good option to offer.
