Choose plastic sheeting with the appropriate thickness so that you may install plastic on the exterior of your windows. Next, take the measurements of the windows, then cut the sheeting to those dimensions. In order to completely enclose the window frame, secure the plastic with double-sided tape.
How do you insulate windows with window film?
During the colder months of the year, installing window insulation film will create an insulating layer over your windows and will help to trap warm air inside of your home. In order to use it, you will need to apply it by first sticking the adhesive side of the insulating film directly onto the surface of the window. After that, you should use a hair drier to apply hot air to the film.
