I have a 1890's terraced house. Ususal stone Victorian affair.

The sliding sash windows are in really good order so I am reluctant to
replace and absolutely will not replace with plastic under any
circumstances.

BUT, about 30-40m from the front of my house, runs what we
affectionately call 'the motorway'. It's actually just slow moving
town traffic but it is starting to 'do my ruddy ed in'.

One firm I spoke to said they could put 6,10,6 double glazed units in
(instead of the usual 4,20,4 size), arguing that 6mm glass would not
vibrate as much as 4mm (seems reasonable). But I am worried that the
weight of the unit will be 'weigh' (sorry) too much. The price they
quoted certainly was.

Then I was sitting in our local Pizza Express last night with cars
going by that were hardly audible, yet single pane glass. Yes, it was
damn thick glass, but it got me thinking.

So, what can everyone recommend? I am more bothered about the noise
than the heat insulating aspect, though that would be nice too, since
my house is like Budleigh Freezington on a cold winters day.

Thanks as always.
Rob
