    I was in a similar position a few years ago, triple for not much more than double. I went with the triple and it's great, hardly noticeable light wise but great noise wise.
    Yes, I was really surprised that it wasn't that much more than double glazing.
    Yes, it was a no brainer for us for that reason. A good selling point later on, too.
    Ours were for bi-folds, so arguably more significant than just windows.
    My main concern was reflections or distortions as they lead out into the garden, but no such worries. 
    As I said, if I didn't know, then I wouldn't be able to tell.
