Hi,
I haven't found any information about this anywhere else so I'm posting here. If anyone has any glazing/secondary glazing/carpentry advice it'd be most welcome.
The project stems from my wonderful victorian bay windows at the front of my house, that looks over a busy road. I don't want to get rid of them, but I've researched secondary glazing panes extensively and you need around 10cm - 15cm of air space between the original panes and the new secondary pane to get maximum decibel reduction. The windows have almost no interior sills on which to install the new secondary glazing units, however - the maximum space between the old panes and the new ones I'd be able to get would be about 2-3inches or 5-7cm. EDIT sorry have checked and this is the width of the existing sills, meaning I'd have even less space than that.
My plan is to build out a frame inside around these windows giving the necessary space for the installation of the secondary glazing panes.
Before I do this however I thought I'd seek advice about:
a) Which kind of wood to use and the best way to attach the frames around the windows (brackets? wall plugs?)
b) Whether the frames would support the weight of the units
c) how best to soundproof the frame (I was thinking sealing it with some sort of acoustic gel and buffering the edges of the secondary glazing units with foam before they go into the new frames.
My pictures give a rough idea of what I'd be doing.

Finished frame with glazing
