How are energy efficient windows like (available in Britain)?
Before having new windows put into our house I was hoping to find out what the best choice would be; so far we've only been told they should have 20 mm distance between the two glass panes which we think is not right. We would very much appreciate if someone could tell us what characteristics we have to look out for in order to optimize energy efficiency if we are to get new windows (the old ones in there are mahogany wood and some of them are double glazed but not all; apparently having them upgraded with double glazing is not possible due to the large distance required between the two glass panes..we are a bit reluctant throwing these old windows out as they are still very good)
Again ,we would be most grateful for a little guidance there

Answers:
There appear to be regulations stipulating a minimum space of 12mm (see link below). You can also save energy by having special energy glass (K?), but this is likely to be in any replacement windows you choose.
You might want to speak to your local council planning department to find out what the building regulations requirements actually are, as I am sure that part of what you are getting is the sales talk from window people. Urgh.
Good luck.
Argon gas filled sealed unit double glazed windows are by far the most energy efficient.
If your old window frames are good and you wish to keep them, you could consider secondary glazing.
they measure the efficiency in wmks
k glass coupled with the argon fill are by far the best.
the only company i am aware of that do argon gas fill as standard is Anglian windows. (expensive but great product)
why not get some advice from them http://www.anglianhome.co.uk/
I would not consider their fitters(contractors)
The gap between panes they do is 4 mill glass 16 mill gap.
if you go for a cheap company make sure you get 4 glass 20 gap
That's the most efficient non gas fill size
ask the double glazer
