double glazing (or similar)

your Pro's and cons please.....
Does it work if you just put it on certain windows in the home or do you have to do it everywhere to get full effect? ie; just in one bedroom to shut out the noise from the traffic outside etc..
I hear it costs a small fortune so just be keen to know whether it's actually worth it.
I knew of someone once who actually ordered double glazing overseas and had it shipped here and it was still cheaper than ordering it here.
