ALTERNATIVE METHOD OF APPLICATION OF ADHESIVE TAPE
For certain types of windows and some angles it is better to install the hook and loop tape on the side of the window. In this way, the window can always be closed when the fabric is installed. IF YOUR WINDOW HAS A SPECIAL SHAPE AND IT CANNOT CLOSE EASILY WHEN THE INSULATION FABRIC IS INSTALLED, YOU CAN JUST REMOVE THE FABRIC FROM THE WINDOW AND CLOSE IT WITHOUT WORRIES.
Another trick is to glue selvage tape to the outside edge of your window frame. This will allow you to open and close your window effortlessly
