Owners and architects usually don't want them when I mention that expected
life before replacement can be as short as 8-12 years. Where they are
already in place and failing I think we should usually replace them with
single pane glazing, but we should preserve at least one of the failed units
in place as an example of the failure so the owners are not sold a bill of
goods in the future.
