add-on window films
does anybody have any experience with add-on window films? I've got an 8 foot sliding glass door (andersen) I inherited when I bought my home. Although they are double pane, I notice a significant difference in heat coming though the glass compared to my newly installed triple-panes on the same wall. The glass etching does not say "HP" or "High perormance", which a local dealer told me would indicate that it was low-e. The door and frame seem in good condition, and I'm trying to find out if add-on window films such as 3m scotchtint is a reasonable option compared to changing out the whole unit. Thanks in advance for any advice.
