How do I install a insulating glazing film?

1- To install an insulating glazing film you should first clean your hands. 2- Wash glass and dry thoroughly using a clean cloth. 3- Clean window frame thoroughly removing dust and grease. 4- Cut adhesive tape to lengths required and apply to top, bottom and sides of window frame. If the room is very cold warm the window frame with a hairdryer before applying the tape. 5- Unfold and cut the film slightly larger than the taped area of the window. Ensure that the inside fold of the film faces the window ready for application. 7- Remove backing paper from tape and press film firmly into place along the length of the tape. Keep the film as smooth as possible to avoid wrinkles. 8- Allow approximately 30 min for the tape adhesive to cure before proceeding to the next step. 9- Holding a hairdryer a few inches away from the film, apply heat starting at the top and working downwards. Keep the hairdryer moving around all the time until the film tightens and wrinkles smooth out. 10- Leave the film to cool for 10 minutes then flock it lightly with your finger: if it makes a drum sound, fitting is complete. 11- Trim off surplus film overlapping adhesive tape.
