Double Glazing instilation in a double brick wall

Hello everyone

I am living in a 70's construction double brick apartment, which is unfortunately fitted with some of the leakiest, flimsiest and poorly fitted aluminium frame windows in history. Pulling apart the architraves and having a closer look, it seems the window panes are virtually floating in the cavity with only a couple of think pieces of wood to hold them in place and bridge the cavity. No wonder they let in so much cold...... also they let in so much sound its as if they are permanently open :(

I was hoping to either DIY install some high grade double glazing or at least have it done for me, but im not really sure about a few things. Ordinarily I wouldn't take the risk but I happened to find some DIY double glazing kits in bunnings warehouse from a company called "polar" (http://www.polarwindows.com.au/) and the instructions for installing them into studwork seems fairly straight forward. They don't however have any instructions for double-brick.

How are these kind of windows fixed to double brick? The frames are certainly chunky enough to span the cavity but I can't really imagine you just hang sit them there, metal against brick and seal it up with a calk gun. Fixing it with pieces of wood would seem to defeat the purpose however.... so im not sure.

Any help would be greatly appreciated, even if I'll never be able to do it i'd still like to understand how it works :U
