Making our windows more efficient, part 2

As promissed, here is the update to the window insulation film project. I decided to go with the Artscape’s Energy Film Window Film because there was no adhesive required. I thought it was going to be a simple “stick it on the window and forget it” type of a deal, but I was mistaken. It turned out to be more involved than I thought.


The biggest problem was that the package didn’t have any installation instructions, I had to go to the Artscape website and click on the “Installation” tab at the top of the screen. That’s where I found out that I needed a soapy water solution sprayed on the window and the film for it to adhere to the window.


Our windows have a faux window pane effect – i.e. they have these vinyl strips glued to the window to look like individual panes. I would love to take those pieces off but it would probably damage the window or leave a residue from the glue. Unfortunately, this means I have to cut out 12 12″x9″ pieces of the film per window. I’ve never really liked that style of window, but as much as I dislike them we’re going to have to live with them for a while, otherwise I wouldn’t have to be going through this effort.


Because of all of the individual pieces I needed to cut out and the extra time involved I was only able put up a test piece on one section. According to the instructions, the window can’t be hot when it is applied so I had to wait until the evening. The next day I did a hand test and found that the part of the window with the film on it was at least 20 degrees cooler than the unprotected “pane”. I’m going to finish the installation this week and then do some temperature checks to get a more accurate figure of the temperature difference between the filmed and unfilmed windows.
