I currently have several broken window panes that I need to replace. I am fairly handy with woodwokring and was hoping to upgrade my nice 80 year old wooden sinlge pane windows to something better (like from 3/32nd glass to maybe 1/8th tempered low-E glass to help with sound and insulation.) Has anyone ever done such an upgrade and if so do you have any comments, tips, techniques or informational websites you used? Thanks.

I converting a family room into a bedroom. I have an opening that is 91-1/4" high and 57-1/2" wide. Initially I was going to install french doors but the guy in the door department informed me that french doors come standard as 60" wide by 80" high or 47"wide by 80" high. He then told me I needed to construct a frame. I know you guys have custom ordering is there a way that I can just order something to fit? Or should I give up the whole french door thing and ATTEMPT to install a sliding pocket door? Either way it looks like I need to invest in some power tools because all I have at the moment is a borrowed power drill :D. Thanks for the help.
