I had some double glazing units replaced by a local firm when I moved into my

condensation was forming on the inside.

Now the same units have become misty again - no condensation as such, just 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
