a
faint film on the inside which looks very ugly (particularly in sunlight).
A
glazier who came to look at them told me that this was quite normal and
that
one couldn't expect any double glazed units to last more than 8 to 10
years.
Is this true? Are there cheapo units around that will fail more quickly?
(Or
conversely more expensive ones that last longer?).

I would appreciate any advice before I go ahead and replace them again.
Thanks


The "faint film" you're getting is also condensation but, unless it's
between the 2 panes, there's probably nothing wrong with the units. If
it's only just started, it may be to do with the strange weather we're
having. I'd reserve judgment until that wind gets back to SW and brings
us some warm stuff

Sorry, I didn't make myself clear. The film is between the two panes. If it
were not I could simply wipe it off (i.e. clean the windows!).

I was told that the space between the panes was originally evacuated, and
when the vacuum fails (after 8 - 10 years) the filming occurs and the unit
needs to be replaced. If this is true I would be tempted to get rid of the
double glazing and go back to normal windows that at least could be cleaned
properly.
