Double pane window installation
 

I have a single pane windows with aluminum frame, and would like to replace it with double pane windows. I would like to hear from any person who has experience in replacing the windows or window replacement professionals. I would like detailed instructions.

Fine Homebuilding magazine has an article on installing vinyl replacement windows in this months issue. I used Jeld Wen vinyl replacements, pocket windows, from Home Depot. I down loaded the instructions from the Jeld Wen website.
