PLEASE HELP: Has anyone got secondary glazing in thier house

[arworld]

I am thinking of putting secondary glazing in our bed room as I hear outside noise early in the morning and it really does have impact on me.

The problem is we already have double glazing windows and thick curtains but I still hear the noise.

We are now thinking of putting secondary glazing.

Has anyone got secondary glazing in their house. And are they effective in terms of reducing noise?

And would anyone be able to offer for me to come and see those in action? thank you!

I had them put in last year by this company - http://www.stormwindows.co.uk

My main aim was to make the house warmer but they have reduced noise too.
