Why cant I install static cling on my double pane windows? Well that is a question that gets asked a lot. In addition as does the question of can I install static cling window tint on my double pane windows? The answer to the second question is no, you cannot. Or you can but it will damage your windows. And the answer to the first takes a lot longer. You cant because there is a gap between the panes known as dead space which acts as an insulator. When static cling window tint is installed on the interior pane of glass it causes the SHGC or Solar heat gain coefficient to increase, which means that the interior pane of glass absorbs and holds more heat. This normally wouldn’t be an issue if it wasn’t for the frame around the two panes. You see, the exterior pane of glass not having the film on it means that the exterior pane of glass will expand at a different rate than the interior pane of glass, the frame which was normally slightly moved by the slight but even expansion of two panes of glass now is being expanded against by one thin pane of glass. This puts strain on the single pane of glass, which in some cases is enough to crack the glass. This is the main reason why many window manufacturers will void the warranty of their windows should a static cling window tint be put on them.
