I have been watching "Grand Designs" with great interest, in particular the way they construct those window walls where sealed double glazed panels are essentially placed in a channel of some sort and siliconed together.

I am planning a glass box extension and want to use this method on 3 external walls (metal post in each corner) to give that "window wall" effect.

For the life of me I cant find anyone that can supply these type sealed double glazed panels in any size and the corresponding aluminium channels, or how to do it.

It seems quite straightfoward to do based on what I have seen.

Can anyone help ?

Many Thanks.
